Text User Task instead of Manual Task

  • Key: BPMN2-301
  • Legacy Issue Number: 15681
  • Status: closed  
  • Source: scch.at ( Christine Natschlär)
  • Summary:

    The first sentence on page 171 states:
    The User Task inherits the attributes and model associations of Activity (see Table 10.3), but does not have any
    additional attributes or model associations.

    I think that in the mentioned sentence "User Task" should be replaced by "Manual Task".
    The sentence is still in the section of the Manual Task and the User Tasks starts afterwards also providing its own statement stating that the User Task inherits the attributes and model associtations of Activity.

    The purpose of this paragraph is to explain that both Choreography Task and Sub-Choreography can have loop markers. Figure 11.12 shows Choreography Task Markers, and Figure 11.22 shows Sub-Choreography Markers

    Then, it should say:
    “Both Choreography Activities can have standard loops and multi-instances. Examples of Choreography Activities with the appropriate markers can be seen in Figure 11.12 and Figure 11.22.”

Conflicting content regarding choreographies.

  • Key: BPMN2-296
  • Legacy Issue Number: 17094

  • Source: Anonymous
  • Summary:

    I was going through the BPMN 2.0 Specifications and found some conflicting
    content regarding choreographies. In section 7.4 Use of Text, Color, Size,
    and Lines in a Diagram, the third indented point of the bullet "The fills
    that are used for the graphical elements MAY be white or clear" states
    that "Participant Bands for Choreography Tasks and Sub-Choreographies that
    are not the initiator of the activity MUST have a light fill. This does
    not seem to be consistent with what is depicted in Figure 7.7 An example
    of a stand-alone choreography diagram. It is also not consistent with the
    discussions on Choreography in the same document in Section 11.4.1

  • Summary:

Merge Collaboration and Choreography in Metamodel

  • Key: BPMN2-278
  • Legacy Issue Number: 15119
  • Status: closed  
  • Source: BPM Advantage Consulting ( Stephen White)
  • Summary:

    Collaborations and Choreographies have a large degree of overlap in underlying capabilities--basically being a collection of Participants and Message Flow. Choreography only adds the sequencing of the Message Flow. It would be useful to be able to take the same interaction model and display it as either a Collaboration or a Choreography. The definition of those views would determine what should be displayed and how they are displayed.
    A merger of the two diagrams in the metamodel would greatly simplify the implementation, add flexibility, and improve BPMN support of other specifications, such as SoaML.

  • Status: closed  
  • Source: BPM Advantage Consulting ( Stephen White)
  • Summary:

    The names Call Conversation and Call Choreography are confusing and incorrect. Conversations and Choreographies are not elements that can be "called."
    Also the Call Activity may be technically correct, it is a term not oriented for business modelers. It would be best to change the terminology for all elements that "call."

  • Reported: BPMN 2.0b1 — Thu, 4 Mar 2010 05:00 GMT
  • Disposition: Resolved — BPMN 2.0
  • Disposition Summary:

    Reason:

    • The change will cause a lot of instability in the spec as it touches so much.
    • As the CallActivity in Orchestration keeps the term "Call" the spec becomes inconsistent.
    • Even if "Call" is a technical term, it seems to be accepted by the BPMN community at least for the Orchestration case. Why should it be inaceptable in the
      Choreagraphy area?
    • "Use" is a very unspecific and frequently used term that makes is difficult to explain the meaning of the C-Activites in sentences like "Use a UseConversation actity to
      reference conversations that are used".
    • Even if the spec is not final, the community starts using the terms from the Beta. These people will be confused by such significant term change.

XML Schema is not strict enough

  • Key: BPMN2-276
  • Legacy Issue Number: 15105
  • Status: closed  
  • Source: SAP SE ( Reiner Hille-Doering)
  • Summary:

    The XML Schemas BPMN20.xsd and Semantic.xsd define lots of global elements. This allows the elements to be used as XML file root. I don't think that this is intended: BPMN 2.0 files should be always rooted with "bpmn:definitions", and only a few elements are allowed as sub elements (including imports, diagrams and all root elements).

    The current design would e.g. make a file be a valid BPMN 2.0 file which consists of a single activity only.

    Document Structure
    A domain-specific set of model elements is interchanged in one or more BPMN files. The root element of each file MUST be <bpmn:definitions>. The set of files must
    be self-contained, i.e. all definitions that are used in a file MUST be imported directly or indirectly using the <bpmn:import> element.
    Each file must declare a "targetNamespace" which MAY differ between multiple files of one model.
    BPMN files MAY import non-BPMN files (such as XSDs and WSDLs) if the contained elements use external definitions.

How to reference particular instances of Data Objects that are Collections

  • Key: BPMN2-275
  • Legacy Issue Number: 15104
  • Status: closed  
  • Source: International Business Machines ( Frank Leymann)
  • Summary:

    How can one address (in an <assignment>, for example) a particular instance of a multi-instance data object, i.e. a data object with attribute isCollection value set to "true"?

    It is unclear why the ioSpecification must be defined with isCollection=true to result in multi-instance execution of the task. Why isn't it sufficient to refer (via the dataInputAssociation/sourceRef element) to a multi-instance data object to trigger multi-instance exection of the task. Is the attribute isCollection needed as attribute of dataInput and dataOutput at all? [Multi Instance Tasks controlled by loopDataInput (Section 10.2.8)]

    I assume that defining a data object with isCollection=false based on an itemDefinition with isCollection=true is not allowed, correct? But the reverse is allowed as shown in the document. The question is why supporting isCollection as attribute of an item definition at all; supporting isCollection with elements using the item definition would suffice. [Item Definition as multi-instance (Section 8.3.12)]

    A corresponding document (BPMN Script invocation.DOCX) with more background has been sent to Tammo van Lessen.

Allow referencing scripts instead of enfocing inline specification

  • Key: BPMN2-274
  • Legacy Issue Number: 15103
  • Status: closed  
  • Source: International Business Machines ( Frank Leymann)
  • Summary:

    Use Case: When using BPMN 2.0 in systems management environments many tasks will be implemented as scripts. Especially, a huge amount of scripts already exist in these environments and BPMN 2.0 should support an easy and straightforward way to allow making use of them as script activity implementations.

    Issue: Scripts to be performed must be copied to the already defined @script attribute to make it inline to the script task. In practice, this is not only redundant but also introduces a lot of potential consistency problems because the proper script might be subject to change; in that case, all copies in all script tasks must be found and adapted accordingly.

    Prososed resolution: Add a new attribute @scriptRef (of type URI or QName) to the scriptTask element. This allows to point to the script to be executed.

    Minor comments: There is no need to introduce the script separately as an operation of some (artificial) interface. This should be clarified.

    The script task refers to a NONE task which has been renamed into Abstract Task: needs to be fixed.

For DI: All graphical elements should have a Semantic Counterpart

  • Key: BPMN2-273
  • Legacy Issue Number: 15102
  • Status: closed  
  • Source: BPM Advantage Consulting ( Stephen White)
  • Summary:

    Most graphical elements have a semantic counterpart. It should be a design principle that all elements follow this pattern. One exception is the Communication Link, which is merely an association between two Elements. The Communication Link, and any other similar DI situations, should be given its own semantic element.

Missing definition of the participant Buyer

  • Key: BPMN2-291

  • Status: closed  
  • Source: Camunda Services GmbH ( Gerardo Navarro Suarez)
  • Summary:

    Table 10.19, the XML serialization of the Buyer process in figure 10.23 (pg. 150) is shown. The process model in figure 10.23 shows a Pool named Buyer. The metamodell provides the possibility to define pools as participants, which have a reference to the process definition. But Table 10.19 doesn’t contain any definition of a participant.

    ##Proposed Resolution: Fixed

    (a) Update Table 10.19 by replacing the XML with the following XML,which adds a collaboration with a participant and a laneSet. The collaboration represents the pool Buyer in figure 10.23 (pg. 150).

Exporter Information Required for BPMN 2 files

  • Key: BPMN2-290
  • Legacy Issue Number: 15161
  • Status: closed  
  • Source: Trisotech ( Denis Gagne)
  • Summary:

    There is a requirement for the “Exporter” of a BPMN 2 file to be identified. Such identification will allow an importing tool to take various appropriate actions to ensure ease of exchange and interchange of BPMN 2 files (for both semantic and diagrams).

    There is substantial practical evidence of the benefits of such information. In fact XMI provides support for such information. You can refer to MOF 2.0/XMI Mapping Specification, v2.1.1, section 4.5.2 and section 4.5. in the XMI spec for description of the <documentation> class, which is part of the XMI model. It contains the nested element <exporter>, and <exporterVersion> which serves this purpose.

    The intention is that any model that is an instance of MOF and serialized in XMI is able to include an instance of <documentation> nested in the root. As the example given by Pete shows:

    More specifically there is the following in the XMI spec :

    <xsd:complexType name="Documentation">

    …

    <xsd:element name="exporter" type="xsd:string"/>

    <xsd:element name="exporterVersion" type="xsd:string"/>

    For example:

    <xmi:XMI>

    <documentation xmi:type=xmi:Documentation>

    <exporter>MagicDraw UML</exporter>

    <exporterVersion>16.8 Beta</exporterVersion>

    </documentation>

    …

    This would require changes to section 8.1 and 8.1.3 of the BPMN 2 spec

    Proposal:

    Add to the tDefinitions xsd complexType:

    <xsd:attribute name="exporter" type="xsd:string" />

    <xsd:attribute name="exporterVersion" type="xsd:string"/>

    This will give two new optional properties (exporter and exporterVersion).

    • At least one incoming sequence flow has at least one Token and
    • for each empty incoming sequence flow, there is no Token in the
    graph anywhere upstream of this sequence flow, i.e., there is no
    directed path (formed by Sequence Flow) from a Token to this
    sequence flow unless

    • the path visits the inclusive gateway or
    • the path visits a node that has a directed path to a non-empty
      incoming sequence flow of the inclusive gateway.

    it does not get clear that the latter path is also not allowed to visit the inclusive gateway.

    I suggest to reword the entire sentence.

    The same applies to the semantics of the complex gateway.

    there is also a directed path formed by sequence flow that
    iv. starts with f,
    v. ends with an incoming sequence flow of the inclusive gateway that has a Token, and
    vi. does not visit the inclusive gateway.
    If the inclusive gateway is contained in a sub-process, then no paths are considered that cross the boundary of that sub-process.
    Upon execution, a Token is consumed from each incoming sequence flow that has a Token. A Token will be produced on some of the outgoing sequence flows.
    In order to determine the outgoing sequence flows that receive a Token, all conditions on the outgoing sequence flows are evaluated. The evaluation does not have to
    respect a certain order.
    For every condition, which evaluates to true, a Token must be passed on the respective sequence flow.
    If and only if none of the conditions evaluates to true, the Token is passed on the default sequence flow.
    In case all conditions evaluate to false and a default flow has not been specified, the inclusive gateway throws an exception."

  • Disposition Summary:

    This issue concerns multiple data objects icons appearing on the same
    diagram, but with the same name and different states, intending to
    represent the same runtime object for the duration of each execution of
    the diagram. The resolution addresses abstract syntax for this, leaving
    execution semantics to be filed as an issue in the RTF.
    In the sentence above Figure 10.47 (ItemAware class diagram), after
    "Data Objects," add "Data Object References,".
    In Figure 10.47 (ItemAware class diagram) add metaclass named
    "DataObjectReference", subclass of ItemAwareElement.
    DataObjectReference has one unidirectional association from it to
    DataObject. This association has multiplicity * on the
    DataObjectReference end and 1 on the DataObject end. The name on
    DataObject end is named dataObjectRef.
    In Section 10.3.1 (Data Modeling), Data Objects subsection, at the end
    of the first paragraph, add:
    Data Object References are a way to reuse Data Objects in the same
    diagram. They can specify different states of the same data object at
    different points in a process. Data Object Reference cannot specify
    item definitions, and Data Objects cannot specify states. The names
    of Data Object References are derived by concatenating the name of the
    referenced Data Object with the state of the Data Object Reference in
    square brackets as follows: <Data Object Name> [ <Data Object Reference
    State> ].
    In Figure 10.48 (DataObject class diagram) add metaclass named
    "DataObjectReference", subclass of FlowElement and ItemAwareElement.
    DataObjectReference with one unidirectional associations from it

    by message flow grouping constructs.
    Remove Subsection 12.3.3 (Correlations) and the sentence in it.

    from ChoreographyActivity. This association has multiplicity 0..1 on
    the ChoreographyActivity end and * on the CorrelationKey end. The
    association end on the CorrelationKey end is named correlationKeys, which

  • Disposition Summary:

    Conversation links are groupings of message flows, so they can be linked
    to activities and events just as message flow can. The resolution
    supports conversation links to activities and events, but not message
    flow to conversation nodes a requested by the issue. This restriction
    is only by textual constraint, if a future RTF would like to loosen it.
    Conversation Link is added to the metamodel to simplify implementation
    of this resolution. The notation for conversation links is changed to a
    double lines, to distinguish them from sequence flows when used with
    activities and events. The forked line end notation for conversation
    links ("crow's feet") is removed to simplify usage and implementation,
    since it is redundant with participant multiplicity notation.
    The resolution assumes the resolution of 14654.

How to represent Process Diagrams and Lanes?

  • Key: BPMN2-259
  • Legacy Issue Number: 15063
  • Status: closed  
  • Source: Adaptive ( Pete Rivett)
  • Summary:

    Taking Figure 10.121 as an example, it’s unclear what the outer box represents in the diagram – is it a graphical Pool representing a Participant named Supplier linked to a PartnerEntityRole also named ‘Supplier’ in turn linked to a Process also called Supplier? Or is it merely a Process called Supplier (in which case it could be better named ‘Supply Process’)? I would have thought the latter, but that does not tie in with my reading of 13.2.3 which states that “A Lane is a sub-partition with a Pool” and “A Pool is the graphical representation of a Participant in a Collaboration (see page 146). It is also acts as a graphical container for partitioning a set of Activities from other Pools, usually in the context of B2B situations.” Likewise Figure 13.4 provides only one interpretation – as Lanes within a Pool not within a Process.

    Though Table 13.1 states that a Process Diagram has at least one LaneCompartment (which is inconsistent with 13.2.3 which states that Lanes are only within Pools) this is inconsistent with the serialization (in Table 10.19) of Figure 10.23 which has no instance of Lane at all. And Figure 10.23 appears to use the Pool notation shown in Figure 13.3

Missing in XML example

  • Key: BPMN2-284
  • Legacy Issue Number: 15147

  • Source: Camunda Services GmbH ( Gerardo Navarro Suarez)
  • Summary:

    On page 180 begins the serialized XML example (table 10.19) of the process model shown in figure 10.23 . The definition of a sequence flow is missing in the serialized XML.

    The process model has 11 flows, but in the XML example there are only 10 sequence flows defined. So one is missing.

    The missing flow is that one between AND - Join (called "OrderAndShipmentMerge") and the user task "Review order".

    I suggest to add a paragraph to 14.1 that describes the instantiating behavior of a receive task.

    In addition, is it intentional that in "In order for the Task to Instantiate the Process it must meet one of the following conditions" on p139, "Instantiate" is written with a capital I?

  • Source: BPM Advantage Consulting ( Stephen White)
  • Summary:

    The two versions of the Multi-Instance loop marker should be reversed. The three horizontal lines looks more like parallism and the three vertical lines look more like sequentialism.

  • Reported: BPMN 2.0b1 — Fri, 9 Apr 2010 04:00 GMT
  • Disposition: Resolved — BPMN 2.0
  • Disposition Summary:

    Reason: Changing the icon for multi-instance activities now will cause a lot of confusions. It will be difficult to ensure that the whole document stays in a consistent state.
    There are also already publications out on the market that use the current notation.
    Even for BPMN 1.x there are examples that use the current "vertical" notation for parallel, e.g. see Steves
    http://www.bpmn.org/Documents/Notations_and_Workflow_Patterns.pdf , Figure 30. So, there would be some kind of incompatibility introduced.
    Which orientation is better to understand for parallel and sequential depends mainly on taste on which axis one assumes time. If you model vertically top to bottom, the
    current notation is good. This is similar like writing a text, or also similar to UML activity and sequence diagrams. Only for the case that you model left-to-right the other
    proposal might make little more sense.
    Conclusion: Changing the meaning now has much higher risk than advantages.

Simplify Use of Callable Elements

  • Key: BPMN2-256
  • Legacy Issue Number: 15060
  • Status: closed  
  • Source: BPM Advantage Consulting ( Stephen White)
  • Summary:

    Callable elements can be simplified. For example, a Global Choreography Task can be a sub-type of Choreography. It would be defined as an "empty" Choreography. A Global Task could be a sub-type of Process, with the same restriction.
    By doing this, then calling elements within the diagram can be more specific about what kind of element they can reference. Thus, a CallActivity can reference a Process and a Call Choreography can reference a Choreography, instead of both referencing Callable Elements with an text based restriction as to what kind of callable element can be referenced.

Clarification of Temporal Sematics of Sequence Flow

  • Key: BPMN2-252
  • Legacy Issue Number: 15049
  • Status: closed  
  • Source: Agile Enterprise Design ( Fred Cummins)
  • Summary:

    While tokens may help explain behavior, the specification should not rely on the concept of tokens to define the normative behavior of model elements.

    Sequence flows represent temporal constraints requiring that an "incoming" constraint be satisfied before a flow element can be executed. The specification should refer to the sequence of execution or the flow of control rather than the flow of tokens.

    While the specification explicitly says that tokens are a theoretical concept for explanation of behavior, the specification refers to the flow of tokens in many places. For example, the end event behavior is described as "The Process will be in a running state until all tokens are consumed."

    Since tokens are not required for compliance, the normative definitions of behavior should not be specified in terms of token flows but in terms of satisfaction of temporal constraints.

    Consistent use of temporal constraint semantics is importnant for specialization of processes (addition of intervening elements) and analysis of processes such as validation of compliance with a choreography.

Contradictory/redundant handing of data and subprocesses

  • Key: BPMN2-269
  • Legacy Issue Number: 15087
  • Status: closed  
  • Source: International Business Machines ( Suzette Samoojh)
  • Summary:

    Consider a process with a Data Object and a Subprocess. The subprocess has an activity. Can you draw a data association from the data object (in the process) directly to the activity (in the subprocess).

    • The introduction of Data Inputs/Outputs for subprocesses implies you should always go through the Data Inputs/Outputs. That is, you must draw the data association from the Data Object to the subprocess Data Input, and then draw another data association from the subprocess Data Input to the Activity inside the subprocess.
    • But then page 216 states that the data object is 'visible' to the subprocess and the activity inside the subprocess, which implies the activity can access it directly without necessarily going through the subprocess data input.

    So, two different means of doing the same thing, with likely different tools assuming/supporting one or the other or both.

Extending via inheritancy is problematic using the BPMN xsd format

  • Summary:

    Extending via inheritancy is problematic using the BPMN xsd format.

    The presence of the 'any' element on tBaseElement creates issues if you create subclasses that reside in a non-BPMN namespace. You cannot add elements to the subclass without violating the Unique Particle Attribution (UPA) rule in XML Schema (http://www.w3.org/TR/2004/PER-xmlschema-1-20040318/structures.html#non-ambig)

    Table 10-19 provide an incorrect serialization. There should be a laneset element with a single lane named : Buyer.

    The use of the string Buyer as process id is also very misleading.

Add an attribute that can identify a rulebase/rule engine for Business Rule Task

  • Key: BPMN2-248
  • Legacy Issue Number: 15040
  • Status: closed  
  • Source: Intalio, Inc. ( Tammo van Lessen)
  • Summary:

    Currently, a Business Rule Task has only an "implementation" attribute that is used to identify the technology used to interact/communicate with a rule engine (e.g. Web Service or any other protocol).

    However, there is no possibility to identify to which rule engine the data should be sent nor which rule set should be processed. I believe that this information is crucial from a vendor perspective.

    My suggestion is to add an anyURI-attribute called "ruleSet" (perhaps there is more generic term). The attribute's value can be resolved at runtime/deployment time by BPMS to identify both, rule engine and ruleset or other rule engine specific settings.

BPMN CMOF File problems

  • Key: BPMN2-246
  • Legacy Issue Number: 15031
  • Status: closed  
  • Source: Thematix Partners LLC ( Edward Barkmeyer)
  • Summary:

    The Beta-1 CMOF files on the server (spec/BPMN/2.0/20090501/cmof.xmi <http://www.omg.org/spec/BPMN/2.0/20090501/cmof.xmi>, spec/BPMN/2.0/20090501/Infrastructure.xmi <http://www.omg.org/spec/BPMN/2.0/20090501/Infrastructure.xmi>, spec/BPMN/2.0/20090501/Semantic.xmi <http://www.omg.org/spec/BPMN/2.0/20090501/Semantic.xmi>) are invalid in several ways:

    (1) The schemaLocation for the UML Infrastructure schema is an EMF URI that returns Error 404. The only elements actually used in the BPMN model are the primitive types. It is preferable to provide only the standard UML URI and assume that any CMOF implementation will have a known source for it.

    (2) The modularization of the Infrastructure Package makes no sense.
    The Infrastructure Package must import Core::Foundation in order to define the associations from Definitions to RootElements, Relationships, and Extensions. Otherwise those data types are undefined. And in the current model, only the association ends owned by Definitions are in the Infrastructure Package; the associations themselves and the non-navigable ends are owned by the Foundation Package.
    [It is not clear what religious motive caused Infrastructure to be removed from the Core Package in the first place. It is documented as part of the Core in the specification. Definitions is a subclass of BaseElement and inheriting the identifier documentation is important.
    If you really want to separate Definitions (and Imports) for some reason, then you need to split Definitions into an Infrastructure version containing only the properties that are wholly contained in the Infrastructure package and a Core version that has the properties that bind Definitions to Foundation elements, including the generalization, and then packageMerge Infrastructure into Core. But then the "reusable" thing in the Infrastructure package has neither a formal id, nor any associated text.]

    (3) Foundation should import the "cmof" Package (which should really be the OMG standard reference) to define Element, for external Relationships and Extensions.

    (4) Infrastructure should import the "interchange" Package that "defines" Diagram, and the "interchange" module should define the class Diagram, not the class NotInSpec. I realize that this is a fudge, but the existing nonsense causes Definitions:diagrams to be a model inconsistency when loading the XMI file into a CMOF repository.

    Yes, it is difficult to get a correct CMOF file out of the EMF libraries, or any UML tool. But it is the only form on the OMG server that can be loaded into a model library for integration with other cmof:Element objects (e.g., from UML or UPDM or SysML or BMM models).
    The XML schemas are worthless for this purpose. So, if you want Extension to work, fix the CMOF file.

Inconsistent/confusing statements around CallActivities and IOSpecifications

    PDF pg 196 states that "Call Activities must not define their own data inputs, InputSets, and outputs, OutputSets but use the data inputs, InputSets, and outputs, OutputSets defined in the referenced CallableElement"

    This reads like CallActivities don't own data inputs/outputs of their own.

    But then PDF pg 225 states that "... the data inputs and outputs of the Call Activity must match with the data inputs, inputsets and outputs, outputsets defined in the callable element".

    This explicitly states that a CallActivity does own data inputs, etc. So then what's the meaning behind the statements on PDF pg 196?

Ambiguity when multiple message flows associated with a choreography task

  • Key: BPMN2-237
  • Legacy Issue Number: 14890
  • Status: closed  
  • Source: Red Hat ( Gary Brown)
  • Summary:

    a choreography task is associated with more than two message flows, or with two message flows that are in the same direction (i.e. same sending and receiving participants), then the ordering of the message flows is ambiguous.

    If the choreography is ambiguous, and process models associated with each participant in the choreography are independently developed, it may mean that the resulting process models may not be able to interact correctly.

    There are a couple of possible solutions:

    1) Only permit a choreography task to have a max of two message flows. If two are defined, then they must be in opposite directions.

    2) If more than two message flows are defined, then an MEP (and possibly other additional supporting information) needs to be specified that makes the ordering explicit. For example, request/response/fault MEP could be specified, where only one message flow could be in one direction (i.e. the request), and all others are in the opposite direction - and the semantics would be that only one of the 'response' message flows could occur. Note: not sure whether it would be necessary to distinguish those flows as one normal response and remaining being fault responses - may be necessary to map to standard rpc pattern.

    "Globalness" should be an attribute of Task, so the taxonomy of
    tasks does not need to be repeated.

  • Disposition: Resolved — BPMN 2.0
  • Disposition Summary:

    We do not consider making all tasks global something necessary. Besides simplicity and simetry, there is no added value to business users, since the refactoring would
    be done by tooling anyway, so they would not see a difference if the metamodel changes in one way or the other.
    We consider this issue to be part of this FTF, maybe a new RFP can handle it.

    Changes to Annex C: Glossary
    (a) Reformat the descriptions of the definitions so that the definition is not repeated in the description. For example, change the beginning of the Activity definition from:
    "An activity is a generic term for work that a company or organization performs via business processes"
    To:
    "Work that a company or organization performs using business processes."
    (b) Remove WfMC definitions from Glossary (some of these definitions will be merged with BPMN terms (see below)
    (c) Remove Workflow Pattern definitions from Glossary
    (d) "Abstract Process" Definition: change definition to "A process that represents the interactions between a private business process and another process or
    participant."
    (e) "AND-Join" Definition: Delete this topic and merge the definition with "Join" (see below)
    (f) "Join" Definition: Replace definition with the following: "A point in the Process where two or more parallel Sequence Flow paths are combined into one Sequence
    Flow path. BPMN uses a Parallel Gateway to perform a Join. Also known as "AND-Join.""
    (g) "AND-Split" Definition: Delete this topic and merge the definition with "Fork"
    (h) "Fork" Definition: Replace definition with the following: "A point in the Process where one Sequence Flow path is split into two or more paths that are run in parallel
    within the Process, allowing multiple activities to run simultaneously rather than sequentially. BPMN uses multiple outgoing Sequence Flows from Activities or Events or
    a Parallel Gateway to perform a Fork. Also known as "AND-Split."
    "Artifact" Definition: remove last two sentences.
    (j) "Association" Definition: replace definition with the following: "A connecting object that is used to link information and Artifacts with Flow Objects. An association is
    represented as a dotted graphical line with an arrowhead to represent the direction of flow."
    (k) "Business Analyst" Definition: replace the definition with "A specialist who analyzes business needs and problems, consults with users and stakeholders to identify
    opportunities for improving business return through information technology, and defines, manages, and monitors the requirements into business processes."

    "Business Process Management" definition: replace definition with the following: "management (for example, process analysis, definition, processing, monitoring and
    administration), including support for human and application-level interaction. BPM tools can eliminate manual processes and automate the routing of requests between
    departments and applications."
    (o) "Choreography" definition: replace definition with the following: "An ordered sequence of message exchanges between two or more Participants. In a Choreography
    there is no central controller, responsible entity, or observer of the Process."
    (p) "Collaboration" definition: replace definition with the following: "of message exchanges between two or more Participants."
    (q) "Compensation Flow" definition: replace definition with the following: "Flow that defines the set of activities that are performed while the transaction is being rolled
    back to compensate for activities that were performed during the Normal Flow of the Process. A Compensation Flow can also be called from a Compensate End or
    Intermediate Event."
    (r) Remove the "Controlled Flow" item.
    (s) "Decision" definition: replace definition with the following: "A gateway within a business process where the Sequence Flow can take one of several alternative paths.
    Also known as "Or-Split.""

    activity. The Process does not traverse this path unless the Activity is interrupted by the triggering of a boundary Intermediate Event (an Exception - see above)."
    "Expanded Sub-Process" definition: replace definition with the following: "A Sub-Process that exposes its flow detail within the context of its Parent Process. An
    Expanded Sub-Process is displayed as a rounded rectangle that is enlarged to display the Flow Objects within."
    "Flow" definition: replace definition with the following: "A directional connector between elements in a Process, Collaboration, or Choreography. A Sequence Flows
    represents the sequence of Flow Objects in a Process or Choreography. A Message Flow represents the transmission of a Message between Collaboration
    Participants.The term Flow is often used to represent the overall progression of how a Process or Process segment would be performed."
    (z) "Flow Object" definition: replace definition with the following: "A graphical object that can be connected to or from a Sequence Flow. In a Process, Flow Objects
    are Events, Activities, and Gateways. In a Choreography, Flow Objects are Events, Choreography Activities, and Gateways."
    (a2) "Intermediate Event" definition: replace the definition with: "An event that occurs after a Process has been started. An Intermediate Event affects the flow of the
    process by showing where messages and delays are expected, distributing the Normal Flow through exception handling, or showing the extra flow required for
    compensation. However, an Intermediate Event does not start or directly terminate a process. An Intermediate Event is displayed as a circle, drawn with a thin double
    line."
    (b2) "Lane" definition: replace the definition with: "A partition that is used to organize and categorize activities within a Pool. A Lane extends the entire length of the Pool
    either vertically or horizontally. Lanes are often used for such things as internal roles (e.g., Manager, Associate), systems (e.g., an enterprise application), or an internal
    department (e.g., shipping, finance),"
    (c2) "Merge" definition: replace the definition with: "A point in the Process where two or more alternative Sequence Flow paths are combined into one Sequence Flow
    path. No synchronization is required because no parallel activity runs at the join point. BPMN uses multiple incoming Sequence Flows for an Activity or an Exclusive
    Gateway to perform a Merge. Also know as "OR-Join.""
    (d2) Remove "OR-Join" and merge it's definition with the "Merge" item.
    (e2) "Message" definition: replace the definition with: "An Object that depicts the contents of a communication between two Participants. A message is transmitted

    (f2) "Message Flow" definition: replace the definition with: "A Connecting Object that shows the flow of messages between two Participants. A Message Flow is
    represented by a dashed lined."
    (g2) "Normal Flow" definition: replace the definition with: "A flow that originates from a Start Event and continues through activities on alternative and parallel paths until
    reaching an End Event."
    (h2) Remove OR-Split and merge definition with Decision
    (i2) Remove Parallel Split item
    (j2) "Participant" definition: replace last sentence in definition with: "In a Collaboration, Participants are informally known as "Pools."
    (k2) "Pool" definition: replace the definition with: "A Pool represents a Participant in a Collaboration. Graphically, a Pool is a container for partitioning a Process from
    other Pools/Participants. A Pool is not required to contain a Process, i.e., it can be a "black box." "
    (l2) "Private Business Process" definition: replace the definition with: "A process that is internal to a specific organization, generally called a workflow or BPM process."
    (m2) "Process" definition: replace the definition with: "A sequence or flow of Activities in an organization with the objective of carrying out work. In BPMN, a Process
    is depicted as a graph of Flow Elements, which are a set of Activities, Events, Gateways, and Sequence Flow that adhere to a finite execution semantics."
    (n2) "Result" definition: replace the definition with: "The consequence of reaching an End Event. Types of Results include Message, Error, Compensation, Signal, Link,
    and Multiple."
    (o2) "Start Event" definition: replace the definition with: "An Event that indicates where a particular Process starts. The Start Event starts the flow of the Process and
    does not have any incoming Sequence Flow, but can have a Trigger. The Start Event is displayed as a circle, drawn with a single thin line."
    (p2) "Sequence Flow" definition: replace the definition with: "A connecting object that shows the order in which activities are performed in a Process and is represented
    with a solid graphical line. Each Flow has only one source and only one target. A Sequence Flow can cross the boundaries between Lanes of a Pool but cannot cross
    the boundaries of a Pool."
    (r2) "Task" definition: Replace third sentence of the definition with the following: "Generally, an end-user, an application, or both will perform the Task."
    (s2) "Token" definition: replace the definition with: "A theoretical concept that is used as an aid to define the behavior of a Process that is being performed. The
    behavior of Process elements can be defined by describing how they interact with a token as it "traverses" the structure of the Process. For example, a token will pass
    through an Exclusive Gateway, but continue down only one of the Gateway's outgoing Sequence Flow."
    (t2) "Transaction" definition: in first sentence, replace "A Transaction is" with "A Sub-Process that represents"
    (u2) "Trigger" definition: replace first sentence with "A mechanism that detects an occurrence and can cause additional processing in response, such as the start of a
    business Process."
    (v2) "Uncontrolled Flow" definition: replace the definition with: "Flow that proceeds without dependencies or conditional expressions. Typically, an Uncontrolled Flow
    is a Sequence Flow between two Activities that do not have a conditional indicator (mini-diamond) or an intervening Gateway."

Section 8.1.5 [Infra] Import statement description is not clear enough

  • Key: BPMN2-196
  • Legacy Issue Number: 14776
  • Status: closed  
  • Source: Object Management Group ( Mariano Benitez)
  • Summary:

    The intention of the import statement is to include an ENTIRE file as a namespace, so I can reference elements defined inside that file.

    The current text says:
    "The Import class is used when referencing external element, either BPMN elements contained in other BPMN Definitions or non-BPMN elements. Imports must be explicitly defined."

    It is not clear that you are importing the entire file (ala BPEL). Also, it is not clear what is the meaning of "Imports must be explicitly defined"

    – Proposal by Mariano Benitez 23/Oct —
    Change the wording to:

    The import class is used to import elements defined externally and make them available for use by elements defined within the scope of the import element.
    The importType attribute defines the style of associated with the element. Both BPMN and non-BPMN imports are allowed.
    For example: This allows importing an XML Schema that will be used inside StructureDefinition elements, or invoking a global task defined in another file.
    Import elements can be defined globally as part of the definitions, so it is available to all elements defined in that definitions, or it can be defined inside a StructureDefinition, which restricts the scope to that element only.

    The names "Standard Loop" and "Multi Instance Loop" are misleading. Actually both allow for creation of a desired number of Activity instances, not just Multi Instance Loops as the spec text states it. So the multiple instance characteristics is true for all loops, also Standard Loops. Thus the naming of the loop types is very misleading.

    Proposal: Go for the well known names (<a href="http://en.wikipedia.org/wiki/Control_flow#Loops">http://en.wikipedia.org/wiki/Control_flow#Loops</a>). Rename Standard Loop to Condition-controlled Loop (or Conditional Loop or Condition-based Loop). Also find a better name for Multi Instance Loop. I´ll try to post some name proposals soon.

    Modelers should be able to define processes independently of whether
    they will be reused in processes or choreographies. Currently the
    information coming in or out of a process is either through data flow or
    through messages, I understand it. The modeler must commit to one of
    these in advance, or define two copies of the process, one with
    messages, the other with data flow. Suzette brought this up separately
    and says a solution was agreed that Mariano will write up. Didn't see

  • Disposition Summary:

    In section 10.3.2 Executions Semantics for Data, add the following text at the end of the section:

    In the case of Throw and Catch Events, given their nature, the execution semantics for data is different.
    When a ThrowEvent is activated, all DataInputAssociations of the event are executed, filling the DataInputs of the Event. Finally DataInputs are then copied to the
    elements thrown by the event (Messages, Signal, etc). Since there are no InputSets defined for Events, the execution will never wait.
    When a CatchEvent is activated, DataOutputs of the event are filled with the element that triggered the event. Then all DataOutputAssociations of the event are
    executed. There are no OutputSets defined for Events.
    To allow invoking a Process from both a CallActivity and via MessageFlow, the StartEvent and EndEvent support an additional case.
    In the case of a StartEvent, the DataInputs of the enclosing process are available as targets to the DataOutputAssociations of the Event. This way the Process
    DataInputs can be filled using the elements that triggered the StartEvent.
    In the case of a EndEvent, the DataOutputs of the enclosing process are available as sources to the DataInputAssociations of the Event. This way the resulting elements
    of the EndEvent can use the Process DataOutputs as sources.

Generalize message flow

  • Key: BPMN2-203
  • Legacy Issue Number: 14785
  • Status: closed  
  • Source: Model Driven Solutions ( Cory Casanave)
  • Summary:

    The specification contains this constraint: Note that Message Flow cannot connect to objects that are within the same Pool.

    There is no reason to have this constraint and it artificially constrains the model. Many process modeling paradigms (including UML) provide for flows between activities within a process. It is common to refactor processes in which case the interactions don't change - but they may move to another pool. From a business perspective we may well have a message between activities, even if we have not delineated all the participants. The constraint should be removed. This could be acheaved by a more general treatment of interactions.

    This would fundamentally change one of BPMN's core concepts, message, which currently is any type of signal exchanged between processes (pools).

    From: mariano.benitez created: Wed, 10 Jun 2009 13:36:58 -0500 (CDT)
    One way or another, we need a resolution for this problem with pools and processes.

    I personally think we should allow message flows between activities of the same process, or even between processes, but without a collaboration diagram. Collaboration diagrams seems like an overkill for me in the case of simple inter-process synchronization (private processes that add up to the big business process).

Semantics for data flow without sequence flow

  • Key: BPMN2-202
  • Legacy Issue Number: 14783
  • Status: closed  
  • Source: NIST ( Conrad Bock)
  • Summary:

    An activity with data flow input and no incoming sequence flows
    should be given an executable semantics. Then the modeler can focus
    on what data activities accept and provide, without the
    complications of sequencing activities. The semantics could apply
    when input data is taken only at the beginning of activity
    execution, and only from output data that is provided at the end of
    execution of a previous activity in the flow. This isn't the same
    as sequence flow with associated data, because each incoming token
    on a sequence flow "enables the activity independently" (see
    13.1.1. Sequence Flow Considerations). An inclusive merge semantics
    for multiple incoming sequence flows (as in
    <a href="http://www.osoa.org/jira/browse/BPMN-117),">http://www.osoa.org/jira/browse/BPMN-117),</a> helps, but doesn't work
    with mult-token activities or subgraphs in common cases (see
    <a href="http://www.osoa.org/jira/browse/BPMN-254)">http://www.osoa.org/jira/browse/BPMN-254)</a>.

  • Disposition Summary:

    We propose to relax the sequence flow (SF) connection rules for activities. Any activity may or may not have incoming or outgoing SF, irrespective of the presence of
    start and end events. The semantics we propose for activities without incoming/outgoing SF is as follows:

    • each activity that does not have any incoming SF is triggered (ie receives an implicit token) upon instantiation of the containing (sub-) process
    • each activity that does not have any outgoing SF is treated as if it would be connected to an implicit undecorated end event.
      This requires the following changes to the spec document (referring to dtc/2009-08-14 ):
      in Sect. 10.2 Paragraph "Sequence Flow Connections"
    • in the sentence "If the Activity does not have an incoming Sequence Flow, and there is no Start Event for the Process, then the Activity MUST be instantiated when
      the Process is instantiated.", delete "and there is no Start Event for the Process,"
    • in the sentence "If the Activity does not have an outgoing Sequence Flow, and there is no End Event for the Process, then the Activity marks the end of one or more
      paths in the Process", delete "and there is no End Event for the Process"
      in Sect. 10.4.2 "Start event",
    • delete this:
      "If the Start Event is used, then there MUST NOT be other flow elements that do not have incoming Sequence Flow—all other Flow Objects MUST be a target of at
      least one Sequence Flow. u Exceptions to this are Activities that are defined as being Compensation Activities (have the Compensation Marker). Compensation
      Activities MUST NOT have any incoming Sequence Flow, even if there is a Start Event in the Process level. See page 314 for more information on Compensation
      Activities. u An exception to this is the Intermediate Event, which MAY be without an incoming Sequence Flow (when attached to an Activity boundary). "
      Change this:
      "If the Start Event is not used, then all Flow Objects that do not have an incoming Sequence Flow (i.e., are not a target of a Sequence Flow) SHALL be instantiated
      when the Process is instantiated. There is an assumption that there is only one implicit Start Event, meaning that all the starting Flow Objects will start at the same time.
      u Exceptions to this are Activities that are defined as being Compensation Activities (have the Compensation marker). Compensation Activities are not considered a
      part of the normal flow and MUST NOT be instantiated when the Process is instantiated. See page 314 for more information on Compensation Activities. "

      part of the normal flow and MUST NOT be instantiated when the Process is instantiated. See page 314 for more information on Compensation Activities.

      "If the End Event is not used, then all Flow Objects that do not have any outgoing Sequence Flow (i.e., are not a source of a Sequence Flow) mark the end of a path in
      the Process. However, the Process MUST NOT end until all parallel paths have completed."
      delete "If the End Event is not used, then "
      in Sect. 14.2.1. "Sequence Flow Considerations"
      change this:
      "If an Activity has no incoming Sequence Flow, and there are no Start Events in the containing Process or Sub- Process, the Activity will be instantiated when the

Enabling multiple events at the same time for the same message

  • Key: BPMN2-201
  • Legacy Issue Number: 14782
  • Status: closed  
  • Source: NIST ( Conrad Bock)
  • Summary:

    When multiple message events for the same message (payload type) are
    enabled at the same time ("executed" at the same time), can they
    receive the same transmitted message? For example, suppose a process
    has parallel gateways resulting in two message events for an Order
    message being executed at the same time. If an order message is sent
    at execution time, can it be received by both message events?

Data Inputs the target of multiple Data Associations

  • Key: BPMN2-221
  • Legacy Issue Number: 14820
  • Status: closed  
  • Source: International Business Machines ( Suzette Samoojh)
  • Summary:

    Can a single Data Input be the target of multiple Data Associations? The spec does not explicitly disallow this.

    What would be the outcome of executing this model - would the last data association defined always overwrite the results of executing prior ones?

    Is there a use-case or scenario where this produces meaning results, or should this pattern be disallowed?

  • Reported: BPMN 2.0b1 — Mon, 23 Nov 2009 05:00 GMT
  • Disposition: Resolved — BPMN 2.0
  • Disposition Summary:

    Add the following paragraph after the last paragraph in Section 10.3.2 Execution Semantics for Data
    Once an InputSet becomes "available", all DataAssociations whose target is any of the DataInputs of the InputSet are executed. These executions fill the Activity
    DataInputs and the execution of the Activity can begin.
    When an Activity finishes execution, all DataAssociations whose sources are any of the DataOutputs of the OutputSet are executed. These executions copy the values
    from the DataOutputs back to the container's context (DataObjects, Properties, etc).
    Execution Semantics for DataAssociation
    The execution of any DataAssociation must follow these semantics:
    a) If the DataAssociation specifies a "transformation" Expression, this expression is evaluated and the result is copied to the targetRef. This operation replaces
    completely the previous value of the targetRef element.
    b) For each "assignment" element specified:
    ) Evaluate the Assignment's "from" expression and obtain the *source value
    ) Evaluate the Assignment's "to" expression and obtain the *target element. The target element can be any element in the context or a sub-element of it (e.g. a
    DataObject or a sub-element of it).
    ) Copy the *source value to the target element.
    c) If no "transformation" Expression nor any "assignment" elements are defined in the DataAssociation:
    *) copy the DataAssociation "sourceRef" value into the "targetRef". Only one sourceRef element is allowed in this case.

    Add the following sentence in Section 14.2.2 Activity, at the end of the bullet that starts with "When some data InputSet becomes available,"
    Please refer to section 10.3.2 for a description of the execution semantics for DataAssociations.

Cardinality of the "sourceRef" association between DataAssociation and ItemAwareElement

    The cardinality on the DataAssociation end is 1. This tells me that any given DataAwareElement must be the source of exactly one DataAssociation.

    This doesn't work:

    • DataAwareElement are not required to participate in data associations.
    • Data Objects can be the source of multiple data associations.

    So the cardinality should be 0..n

Unclear/contradictory handling of visualized Data Inputs/Outputs

  • Key: BPMN2-219
  • Legacy Issue Number: 14818
  • Status: closed  
  • Source: International Business Machines ( Suzette Samoojh)
  • Summary:

    The spec does not provide much clarification on how the Data Inputs/Outputs notation is used.

    As an example, consider a process that is calling another process. The called process has Data Inputs and Data Outputs.

    If I create a data association from the calling process to the Call Activity, clearly the target of that data association would be a data input of the called process.
    And yet the spec states that:

    • DataInputs MUST NOT have incoming DataAssociations.
      So, there's a contradiction here. DataAssociations do and should target DataInputs.

    Or, is that statement intended to describe visualization of the DataAssociation (i.e. the DataAssociation visually stops at the CallActivity boundary and does not visually connect to the Data Input, even if it is actually connected in the semantic model)?

    If the latter, why not allow the Data Association to connect to the Data Inputs? Doing so would result in a more explicit visualization of the underlying semantics. If I had multiple Data Inputs, I would be able to tell at a glance which Data Input is being targetted by which Data Association.

These two ways of tying process instantiation and gateway execution together need to be reconciled.

    Proposal: Preferably, get rid of the instantiate flag and allow the behavior described in 8.4.1 for all gateways, including the event-based gateway. Alternatively, introduce an instantiate flag for all gateways (or for those where it makes sense), and describe the relationship between no incoming sequence flow and the flag.

General [Metamodel] Double-check attributes that are enumerated types, and their extensibility needs

  • Key: BPMN2-210
  • Legacy Issue Number: 14798
  • Status: closed  
  • Source: International Business Machines ( Matthias Kloppmann)
  • Summary:

    Description of issue: The meta-model contains attributes that are conceptually enumerated types. Sometimes their set of values needs to be extensible, sometimes their set of values is closed within the scope of the spec. The spec needs a consistent approach for both types of enums.

    Proposal: Presumably, enums with a closed list should be defined as enums in the metamodel, while enums that are extensible should be defined as string. Better ways to render this may exist. The outcome of the decision must be applied consistently throughout the spec

INCORRECT/IMCOMPLETE REFERENCES AND DEFINITIONS IN GLOSSARY

  • Key: BPMN2-236
  • Legacy Issue Number: 14880
  • Status: closed  
  • Source: Atos Origin ( Lyndon Roy)
  • Summary:

    Glossary in Annex C contains a number of definitions of, and references to, workflow patterns that were incorrect in version 1.0 of the spec and are still incorrect in version 2.0.

    For example, see the following definitions:
    Deferred Choice references workflow pattern #17 ­ actually Deferred Choice is pattern #16;
    Discriminator references workflow pattern #8 ­ actually Discriminator is pattern #9;
    Implicit Termination references workflow pattern #12 ­ actually Implicit Termination is pattern #11

    Also the URL for these workflow patterns has changed (All pages from 'tmitwww.tm.tue.nl' have moved to the server 'is.ieis.tue.nl' - although the latest patterns can actually be found at http://www.workflowpatterns.com/).

    May I suggest that the entire contents of the Glossary are reviewed against the latest set of workpatterns (http://www.workflowpatterns.com/documentation/documents/BPM-06-22.pdf) and ensure that the correct pattern numbers are used. I would also like the glossary to be extended to cover the extra workflow patterns that have been defined beyond van der Aalst's original 20 (or 21 if you include pattern #9a)and that can can be implemented using BPMN notation - (www.workflowpatterns.com/documentation/documents/BPM-06-17.pdf might give useful guidance for this (even though it relates to BPMN v1)).

  • Reported: BPMN 2.0b1 — Thu, 3 Dec 2009 05:00 GMT
  • Disposition: Resolved — BPMN 2.0
  • Disposition Summary:

    Called collaborations can have messages that don't have the correlation
    keys of the caller. The internal structure of messages is not specified
    in BPMN, but correlation keys applying to message flow establish
    property requirements on the contents of the message. The correlation
    keys applying to a message flow are all the keys of the containers of
    the message flow, including containers transitively through calls of
    collaborations or choreographies.
    Above Figure 8.18 (The Correlation Class Diagram) insert a new
    paragraph:
    Correlation can be applied to message flows in Collaboration and
    Choreography, as described in Chapters XXXCollaboration and
    XXXChoreography. The keys applying to a message flow are the keys of
    containers or groupings of the message flow, such as Collaborations,
    Choreographies, and Conversation Nodes, and Choreography Activities.
    This might result in multiple correlation keys applying to the same
    message flow, perhaps due to multiple layers of containment. In
    particular, calls of Collaborations and Choreographies are special
    kinds of Conversation Nodes and Choreography Activities, respectively,
    and are considered a kind of containment for the purposes of
    correlation. The correlation keys specified in the caller apply to
    message flow in a called collaboration or choreography.

Persistent versus transient event trigger

  • Summary:

    Define for intermediate messages (intermediate event trigger) if the message should be persisted in the process scope when the intermediate message is not yet active.

    http://www.workflowpatterns.com/patterns/control/new/wcp24.php

    It relates to e.g. the following on page 226 in the BPMN 2.0 Beta 1 specification:

    “If the Event is used to “catch” the Event Trigger, then the token will remain at the Event until the Trigger occurs (e.g., the Message is received).”

Pools multiplicity

  • Key: BPMN2-192
  • Legacy Issue Number: 14754
  • Status: closed  
  • Source: Bruce Silver Associates ( Bruce Silver)
  • Summary:

    Table 9-1 says a diagram containing pools, i.e. Collaboration, must contain 2 or more. Then is says "Note that the multiplicity of the pools model association is an open issue and may be changed in a later revision of the specification," but it is unclear whether this means the minimum of 2 pools in a diagram or relates to the MI marker on pools. If the former, I think the minimum should be 1 and it should not wait until a later revision of the sepcification. The reasons are
    1) backward compatibility with BPMN 1.1, in which all BPDs were assumed to have at least one pool, whether boundary visible or not; and
    2) ability for modelers to create diagrams with just one pool, labeled with name of the process... and be able to create schema-valid xml from it.

    Also... following fig 9-4 it says " ...the Activities that represent the work performed from the point of view of the modeler or the modeler's organization may be considered "internal" Activities and are not required to be surrounded by the boundary of their Pool...". This is only true if all the activities are part of a single process (orchestration). I think better to say, "...a single process that represents the work performed from the point of view of the modeler or the modeler's organization may be considered "internal" and is not required to be surrounded by the boundary of its Pool...".

  • Summary:

    Type: Technical

    Description of issue: The execution semantics for exclusive gateways correctly states that "the conditions [of the outgoing sequence flows] are evaluated in order". However, the meta-model for an exclusive gateway does not allows for the specification of that order.

    Proposal: Using the "appropriate means" (prototype statement?), ensure the relationship from a FlowNode to its outgoing sequence flows is an ordered collection, rather than a set. This provides ordering not only for an exclusive gateway, but for all FlowNodes, but that doesn't seem to harm.
    In the XSD, where the sequence flows reference their source node rather than vice versa, an additional attribute or element to render the order may be needed, or the representation of sequence flow in the XSD may need to be revised.

Diagram Interchange should align with Diagram Type Definition

  • Summary:

    This summarizes a conversation with Maged, we agreed an issue should be
    filed. He said there were two approaches to diagram interchange (which
    he can explain more about). The one in the IOS submission was chosen
    for expediency and IBM will not be submitting it to the OMG's Diagram
    Type Definition RFP (DTD). The differences between the approaches is
    too much to resolve in an FTF. The IOS submission should use the same
    diagram interchange as IOS members (IBM at least) are submitting for
    DTD. Then any remaining differences between IOS and the later DTD
    adoption can be resolved in FTF.

    [OMG 14750] [Section 10.2.3] Editorial: protocol attribute on the transaction subprocess class seems to have a wrong description - TransactionMethod values not explained
    This is the description Transaction->protocol attribute in 0.9.2 (page 156):

    The elements that make up the internal Sub-Process flow.
    This association is only applicable when the XSD Interchange is used. In the case
    of the XMI interchange, this association is inherited from the
    FlowElementsContainer class.

    Also, the TransactionMethod values are not fully explained. I can infer compensate, but I don't understand Store or Image.

    I believe we need to be more clear/explicit when describing several aspects of compensations. I base this on 0.9.2

    • We should made clear on each case what context is used in compensation. This is a refinement of the snapshot concept, but it needs clarification in this cases:
      • Boundary event handlers: it only mention "black-box" compensation, when it should clearly state that the current state is used.
      • inline event sub-processes: they mention the snapshot when the process is completed, but there is no mention to the case when the compensation is triggered while the subprocess is still running. Also it should be described that the parent scope used in the compensation is the current one, even when the compensated subprocess uses the snapshot context.

Beta 1 [Section 12.1.2] - Use of the term "BPMN" in class names

  • Key: BPMN2-186
  • Legacy Issue Number: 14747
  • Status: closed  
  • Source: International Business Machines ( Suzette Samoojh)
  • Summary:

    Many classes in the visual model start with BPMN. For example, BPMNDiagram, BPMNShape, etc.

    Given that this metamodel is part of the BPMN spec, including BPMN in class names seem extraneous. Certainly we don't do so in the semantic metamodel, so there is an inconsistency in style. Also, this style of naming generally isn't considered a recommended practice. What if BPMN is renamed in the next version?

    Is there a real need for this pattern?

    Comments:
    From: oliver.kieselbach created: Thu, 15 Jan 2009 06:29:07 -0600 (CST)
    I personally don't have a strong opinion about the general naming. Two motivations were driving us here: 1) we wanted to have names which clearly differentiate between a visual MM element from the corresponding semantic element to avoid confusion when talking/discussing/describing elements. 2) when Maged has shown us the Diagram Definition concept and the examples for the UML intrumentation of this DD MM, he also used names like "UMLClassDiagram", "UMLConnector" etc.

TimerEventDefinition: clarification of the expected result of the timeCycle and timeDate expressions

  • Key: BPMN2-168
  • Legacy Issue Number: 14722
  • Status: closed  
  • Source: Object Management Group ( Mariano Benitez)
  • Summary:

    These attributes of the TimerEventDefinition are expressions, there is no mention of the result type. Also it would be useful to describe how this values are used (timeDate defines the next moment the time will trigger, while timeCycle defines an interval that is added to "now" to define the next moment).

    Another thing that is not described is the moment when theses expressions are evaluated. Intuitively I think it is in the moment after the trigger is executed, and for the first time, the moment it is activated.

    Following the BPEL mapping, the timeDate expression should return an XSD DateTime element and the timeCycle an XSD Interval (Period).

    I think it is necessary to clarify this in the execution semantics so people understand what type of behaviour is expected from this event.

    I can make the changes if necessary.

    ##Original Info: (Severity: Significant - Nature: Revision)

    According to the spec text, DataInputAssociation and DataOutputAssociation do not define any attribute.

    In the XSD they both own define sourceRef and TargetRef.

    These elements should be part of the parent class. (there is no problem in moving them up since both definitions are similar (cardinality and types).

    Also:

    In page 202 of Beta 1 it says:
    "The DataInputAssociation element inherits the attributes and model associations of FlowElement (see Table 10-62), but does not contain any additional attributes or model associations."

    But it should say DataAssociation.

DataAssociations: How do we support literals?

  • Source: Object Management Group ( Mariano Benitez)
  • Summary:

    DataAssociations and Assigments correctly allow mapping between data elements.

    Now, there is no way to do a simple mapping of a literal to a data input.

    An assignment could be used to solve the problem, but then you are forced to include a dummy sourceRef to fullfil the requirement of at least one source ref.

    A simple solution would be to allow 0 zero source refs, and keeping the restriction of the scope of the assignment to the souce refs.

  • Disposition: Resolved — BPMN 2.0
  • Disposition Summary:

    1. Add the following introductory paragraph motivating the need for correlation:
    Business processes typically may run for days or even months, requiring asynchronous communication via messages. Also, many instances of a particular business
    process will typically run in parallel, e.g., many instances of an order process, each representing a particular order. Correlation is used to associate a particular
    message to an ongoing conversation between too particular business process instances. BPMN allows using existing message data for correlation purposes, e.g., for
    the order process, a particular instance can be identified by means of its order ID and/or customer ID, rather than requiring the introduction of technical correlation
    data.
    2. Add a footnote to the next paragraph clarifying that it also refers to message events – here is the original paragraph with the suggested footnote in *** ***:
    The concept of Correlation facilitates the association of a Message to a Send Task or Receive Task***All references to Send or Receive Tasks in this section also
    include message catch or throw events – they behave identically with respect to correlation*** in a
    Conversation, a mechanism BPMN refers to as instance routing. It is a particular useful concept where there is no
    infrastructure support for instance routing. Note that this association can be viewed at multiple levels, namely the
    Conversation, Choreography, and Process level. However, the actual correlation happens during runtime (e.g., at
    the Process level). Correlations describe a set of predicates on a Message (generally on the application payload) that
    need to be satisfied in order for that Message to be associated to a distinct Send Task or Receive Task. By the same
    token, each Send Task and each Receive Task participates in one or many Conversations. Furthermore, it identifies
    the Message it sends or receives and thereby establishes the relationship to one (or many) CorrelationKeys.

    The 'mixed' setting does not need to be redeclared. It is transitively inherited. tExpression inherits it from tBaseElementWithMixedContent. tFormalExpression also (and thus it does not need to be redeclared there).

    Business modelers will usually take the term "service" in the business

[XSD] Documentation and ScriptTask (and probably expressions) should be stored as CData elements and not String attribut

  • Key: BPMN2-177
  • Legacy Issue Number: 14733
  • Status: closed  
  • Source: Object Management Group ( Mariano Benitez)
  • Summary:

    Documentation and the scripts are formatted text, we should keep the format (spaces, tabs) that the user defined.

    Storing formatted text as string attributes makes it impossible to do so, since it turns the attributes quite big and looses the format.

    It would be better if we store any formatted text as a CDATA element, so we can easily keep the format.

    Proposal: change the XSD for documentation, script task and formal expressions to use a CDATA element instead of a string attribute.

    In above sample, the targetRef of the data input association refers to a DataInput object of process 'CalledProcessNotServiceEnabled'
    and the sourceRef of the data output association refers to a DataOutput object of the called process.

    The proposal is to modify the XML-Schema type of sourceRef and targetRef from xsd:IDREF to xsd:QName to allow references to

    In this particular case, the submission has one already ("item", as in

    accomodate informational and physical flows. I think it would be good
    to have uniform terminology covering both information and physical
    things, for example:

    Message Flow => Item Flow
    (Message appears redundant with ItemDefinition, or Message could be
    a subclass of ItemDefinition for those items that happen
    to be used in Item Flows)
    Data Object => Item Object
    DataInput => ItemInput
    DataOutput => ItemOutput
    DataState => ItemState

    So much of BPMN's market is modeling businesses in general rather than

    Currently the MM contains a bidirectional relationship between Interface and ServiceRef. This is also represented in the XSD, where the Interface complexType has an element that references a ServiceReference, and the ServiceReference complexType has an element that references an Interface.

    In the Samples meeting, it was raised that the Interface->ServiceReference relationship was not needed in the XSD. This discussion resulted in several outstanding questions:

    • If it doesn't belong in the XSD, should it be in the MM?
    • Tool vendors would find this convenient to have. But is that an implementation issue?
    • This likely isn't the only case. Need to have a broader discussion.
    • What is the purpose of the MM? How are we positioning it?
    • If the MM is for portability, then should the arguments used against the XSD also apply to the MM?

The importing definitions should be able to assign aliases to the imported elements for use within the importing definitions.

    -------------------------------------------------------------------------------------------------------------------
    Proposal to review: [Suzette Samoojh - March 18, 2009]
    -------------------------------------------------------------------------------------------------------------------

    Assumption: "Aliasing" is required when you need to use an existing element, but wish to label it differently based on a usage context.
    Two known use-cases:

    • A Participant references a Role (or Entity) and wishes to apply a name that is different from the Role (or Entity) name.
    • A CallActivity references a CallableElement and wishes to show a name that is different from the name of the CallableElement.

    Proposal: Use existing 'name' attributes to achieve this.

    • Participant.name: If specified, serves as the 'alias' for the referenced Role or Entity. If unspecified, the original name of the Role or Entity is used.
    • CallActivity.name [inherited from FlowElement]: Ditto
      No MM changes needed. Just spec text.

    If anyone has an example that the above does not satisfy, please post it.
    [Note that a concrete example then means we will tackle this issue in a samples-driven manner].

Beta 1: Section 10.2 Activities: Move User Task Instance Attributes to the higher level Activity element

  • Key: BPMN2-181
  • Legacy Issue Number: 14739
  • Status: closed  
  • Source: BPM Advantage Consulting ( Stephen White)
  • Summary:

    Since all activities have performers and priorities. it makes sense to be able to use the actual performer or priority of any activity in the definition of any other activity. E.g., the performer of this activity cannot be the same as that activity. Performers can do the work as in User Tasks, or just be stakeholders or authorizers, etc. for any activity (including sub-processes). Right now only User Activities have these instance attributes. Moving the attributes to the Activity level would allow other activities this capability.

  • Reported: BPMN 2.0b1 — Fri, 20 Nov 2009 05:00 GMT
  • Disposition: Resolved — BPMN 2.0
  • Disposition Summary:

    These instance attributes are defined for User Tasks only, as they are needed for different human interaction scenarios.
    For other task types, e.g. Receive Task, Send Task, Service Task, Business Rule Task the value of having these instance attributes is not clear. E.g. It is not clear what
    would be the Actual Owner of a Receive Task or a Send Task.
    The proposal is to close this issue with no changes to the specification.

Add business-level presentation attributes to user task: subject and description

  • Key: BPMN2-180
  • Legacy Issue Number: 14736
  • Status: closed  
  • Source: International Business Machines ( Matthias Kloppmann)
  • Summary:

    From the human interactions example:
    Need to add business-level presentation attributes known from BPEL4People, namely subject and description. This should include the ability to specify presentation parameters - needs discussion. Without these, the user task capability is not rich enough for serious direct execution, but will always require mapping to and enrichment in BPEL4People.

  • Reported: BPMN 2.0b1 — Fri, 20 Nov 2009 05:00 GMT
  • Disposition: Resolved — BPMN 2.0
  • Disposition Summary:

    Rather than copying the various BPEL4People elements to the BPMN spec, we should modify the BPMN spec as follows:
    Text in section "10.2.4 Human Interactions"
    Current:
    The User Task inherits the attributes and model associations of Activity (see Table 10.3). Table 10.13 presents the additional attributes and model associations of the
    User Task.
    New:
    The User Task inherits the attributes and model associations of Activity (see Table 10.3). Table 10.13 presents the additional attributes and model associations of the
    User Task. If implementations extend these attributes (e.g., to introduce subjects or descriptions with presentation parameters), they SHOULD use attributes defined
    by the OASIS WS-HumanTask specification.

Are Conditional Start Events executable?

  • Key: BPMN2-133
  • Legacy Issue Number: 14680
  • Status: closed  
  • Source: International Business Machines ( Suzette Samoojh)
  • Summary:

    Are ConditionalStartEvents executable? What data are they able to access?

    Note that the spec states that executable ConditionalStartEvents must have a FormalExpression. So the spec implies they are executable. But it doesn't provide guidance on what data context would be provided for that FormalExpression.

    Section 10.4.2 Start Event
    Table 10.3 - Top-Level Process Start Event Types
    Change row: Conditional
    Original (Description column)
    This type of event is triggered when a Condition such as "S&P 500 changes by more than 10% since opening", or "Temperature above 300C" become true. The
    Condition Expression for the Event must become false and then true before the Event can be triggered again.
    If there is only one (1) EventDefinition associated with the Start Event and that EventDefinition is of the subclass ConditionalEventDefinition, then the Event is a
    Conditional Start Event and MUST be displayed with a lined paper marker (see the figure to the right).
    Proposal (Description column)
    This type of event is triggered when a Condition such as "S&P 500 changes by more than 10% since opening", or "Temperature above 300C" become true. The
    Condition Expression for the Event must become false and then true before the Event can be triggered again.
    The Condition Expression of a Conditional Start Event MUST NOT refer to the data context or instance attribute of the process (as the Process instance has not yet
    been created). Instead, it may refer to static process attributes and states of entities in the environment. The specification of mechanisms to access such states is out of
    scope of the standard.
    If there is only one (1) EventDefinition associated with the Start Event and that EventDefinition is of the subclass ConditionalEventDefinition, then the Event is a
    Conditional Start Event and MUST be displayed with a lined paper marker (see the figure to the right).

Contradiction in constraint for Start Events in Event Subprocess

  • Key: BPMN2-132
  • Legacy Issue Number: 14679
  • Status: closed  
  • Source: International Business Machines ( Suzette Samoojh)
  • Summary:

    Apparent contradiction, assuming I'm reading the constraint right.

    The spec states that "An Event Sub-Process MUST have a single Start Event". I interpret this to mean exactly one.
    And yet the spec allows a Start Event with a Multiple or Parallel Multiple event definition. These are short-hand for multiple Start Events, each with a single event definition. Hence a contradiction in functionality and intent.

    Recommend updating the spec constraint to state "An Event Sub-Process MUST have at least one Start Event".
