The reference to sub clause 2.2 should be for sub clause 2.3. The reference to sub clause 2.3 should be for sub clause 2.4. Finally, the reference to subclause 2.4 should be for sub clause 2.5.

    Original passage:
    The implementation claiming conformance to the Process Modeling Conformance type SHALL comply with all of the
    requirements set forth in sub clause 2.1. The implementation claiming conformance to the Process Execution
    Conformance type SHALL comply with all of the requirements set forth in sub clause 2.2. The implementation claiming
    conformance to the BPEL Process Execution Semantics Conformance type SHALL comply with all of the
    requirements set forth in sub clause 2.3. The implementation claiming conformance to the Choreography Conformance
    type SHALL comply with all of the requirements set forth in sub clause 2.4. The implementation is said to have BPMN

  • Summary:

    There is a list of non-operational elements in the introduction to the section *13. BPMN Execution Semantics. The Ad-Hoc Process is in the list. However, in chapter **13.3.5 Ad-Hoc Sub-Process* its execution semantics is described in detail. So, I think the "details needed to execute them on an engine" are given. It seems, the Ad-Hoc Sub-Process is in fact operational and should be removed from the list.

    PS: There is no "Ad-Hoc Process". The "Sub-" is missing.

Mistake in Table 7.2

  • Key: BPMN2-318
  • Status: open  
  • Source: - ( Sebastian Handwerker)
  • Summary:

    I found a mistake in the BPMN 2.0.2 specification.

    https://www.omg.org/spec/BPMN/2.0.2/PDF

    On Page 37:

    "The attributes of Tasks and Sub-Processes will determine if they are repeated or performed once (see page 190). A set of three horizontal lines will be displayed at the bottom-center of the activity for sequential Multi-Instances (see upper figure to the right).
    A set of three vertical lines will be displayed at the bottom-center of the activity for SEQUENTIAL Multi-Instances (see lower figure to the right)."

    The second "sequential" is wrong. The vertical lines are for PARALLEL Multi-Instances.

    The corrected form is the following:

    "The attributes of Tasks and Sub-Processes will determine if they are repeated or performed once (see page 190). A set of three horizontal lines will be displayed at the bottom-center of the activity for sequential Multi-Instances (see upper figure to the right).
    A set of three vertical lines will be displayed at the bottom-center of the activity for PARALLEL Multi-Instances (see lower figure to the right)."

Wrong word used. And wrong page reference

  • Key: BPMN21-441
  • Status: open  
  • Source: Public servant at the Customs office ( Johan Clemmesen)
  • Summary:

    I believe I have found one small mistake in the BPMN specification 2.0, but it has two occurrences.

    The mistake is where the sentence states two times "business process runtime", that perhaps should be altered to "business process engine"?

    It is here:

    10.2.4 Human Interactions
    10.2.4.1 Tasks with Human involvement
    In many business workflows, human involvement is needed to complete certain Tasks specified in the workflow model.
    BPMN specifies two different types of Tasks with human involvement, the Manual Task and the User Task.
    A User Task is executed by and managed by a business process runtime. Attributes concerning the human involvement, like people assignments and UI rendering can be specified in great detail. A Manual Task is neither executed by nor managed by a business process runtime.

    Also on page 163.

    There is a wrong page referencelink, because it links to itself on page 163, where it should link to "10.2.4.1 Tasks with Human involvement" instead.

    "See “User Task” on page 163 within the larger section of “Human Interactions” for the details of User Tasks"

fairly basic errors in some of your example flows

  • Key: BPMN21-440
  • Status: open  
  • Source: Ealing Council ( Louise McDonagh)
  • Summary:

    I have just started going through the 'Business Process Model and Notation, v2.0' document and come across some fairly basic errors in some of your example flows. On the one hand BPMN is very prescriptive, yet in the execution of the examples it is extremely lax and erroneous. I have not got very far into the document yet as it very heavy going, but 2 cases in point where your examples are poor: figure 7.1, 'Approve or Reject Policy' should be two mutually exclusive processes, one to reject and the other to approve, which should have 2 separate outcomes. If you are wishing just to show a high level articulation of this dependency, then the process should be phrased as 'Make Policy Application [Request] Decison'. The other process that jumps out as logically unsound is figure 7.3, example of collaboration process. There are 2 swimlanes, one for patient and one for doctor surgery. 'receive medicine request' is a 'pharmacy' function so should be in a '!
    pharmacy' pool. The way this process flows, there is no point in issuing a prescription request to the patient whose only duty is to present it back to the same surgery. Prescriptions requests have to go to a pharmacy, not the doctor.

All None Start Events should get a token at instantiation, if the Top-level Process or Global Process (or even Sub-Process) contains multiple Non Start Events

  • Key: BPMN21-433
  • Status: open   Implementation work Blocked
  • Source: TU Berlin ( Kai Grunert)
  • Summary:

    Section 10.5.2 on page 238 states:

    If the Process is used as a global Process (a callable Process that can be invoked from Call Activities of other Processes) and there are multiple None Start Events, then when flow is transferred from the parent Process to the global Process, only one of the global Process’s Start Events will be triggered. The targetRef attribute of a Sequence Flow incoming to the Call Activity object can be extended to identify the appropriate Start Event.

    1. Bug: the text only mentions "Global" processes and not "Top-level" processes, which is another but similar category of processes (p. 239). I find no semantic definition about multiple None Start Events in Top-level processes. I think, it should be the same semantic as for Global processes.

    2. Bug:

    As already mentioned in Bug report BPMN21-413 (https://issues.omg.org/issues/BPMN21-413) there is a semantic inconsistency with the definition of the process instantiation (also Section 10.5.2 on page 238):

    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.

    To bring both text passages together, I assume the term "Flow Objects" refers more likely to "Activities", because multiple start events are usually handled in an exclusive manner (defined at multiple places in the specification).
    *But, in my mind there is no semantic difference between an Activity A with no incoming sequence flow and Activity A connected to a None Start Event.* (This just seems to be a modelling preference.)
    So, the question is, how to handle multiple None Start Events in a Global and Top-level process? Exclusive (like the other typed start events) or Inclusive (like Activities without an incoming sequence flow) semantics?

    Solution:

    To stay consistent (no semantic difference between an Activity with or without a None Start Event), I plead for the inclusive semantic, i.e. to put a token into every None Start Event if the process was instantiated via a None Start Event.
    If the process is instantiated via a typed start event, the exclusive semantic should remain.

    Additionally, this is more user-friendly from a modeling perspective than the alternative: if Start Events have to be used (maybe because of a modeling guideline), the parallel semantic would require to have one None Start Event connected to a Parallel Gateway connected to all parallel-executable Activities. This could look very messy compared to one None Start Event at each Activity.

    The disadvantage is the difficulty to model/implement the exclusive start if it is needed. In my experience I have rarely seen it and the inclusive start is way more often required for multiple None Start Events.
    But let's look into that: For a Global (callable) process you can still use the existing targetRef attribute on the incoming sequence flow to refer to/instantiate just one None Start Event.
    None Start Events are also typically used for a manual process start in a process automation engine. If it is really intended to just put a token into one specific None Start Event, you could alternatively 1. use a Message Start Event or 2. the process engine can offer a way to just start a specific None Start Event.

    3. Related Improvement:

    If the semantic will be defined as suggested in Bug 2 for multiple None Start Events, it is also possible and useful to allow multiple None Start Events in embedded Sub-Processes. The entry into the Sub-Process would put a token into every existing None Start Event.

Confusing definition of LinkEventDefinition's fields "sources" and "target"

  • Key: BPMN21-432
  • Status: open  
  • Source: signavio.com ( Philipp Maschke)
  • Summary:

    We recently had a dispute with a customer, who wanted to use a different BPMN tool for downstream processing of certain process models exported from our tool.
    While analysing their claim, I found confusing definitions for the LinkEventDefinition:

    The textual specification for the LinkEventDefinition (and especially the table 10.98) defines three additional fields (compared to the EventDefinition): name, sources and target. All three are listed in the table 10.98 as "attributes":

    However, the following XSD definition actually specifies only the name to be an XML attribute while target and sources are defined as XML child elements - see table 10.115.

    As far as I could tell from a quick scan, all other "attributes" listed in tables with such a name are actually also XML attributes.
    So I can see how there could an interpretation, that the target of a link event should be an XML attribute and not a child element.
    Am I correct in assuming that the XSD is binding and thus "target" should really not be an attribute of the linkEventDefinition element, but rather a child element?
    If so, then this section should be defined in a less ambiguous way.

  • Summary:

    Software vendors seem to implement it as a mandatory step to close every XOR Gateway with a XOR Join.

    Just a few sources state that the usage of the XOR Join gateway is optional.

    Since i don't see a definitie logical reason, to use the XOR Join gateway at all, i was researching the OMG BPNPs specifications, which seem not to clrarly state how to handle XOR Joins either.
    Therefore i open up this issue. Could you please state:

    Please excuse that i ask this question by opening this bug report. SInce i wasn't able to find a definite answer to the given question in the specification, it may more be a bug in terms of an missing clarification, which seem to lead to the situation, that certain software providers handle the use of a XOR Join Gateway in a way, that seem to be redundant, from a strictly logical perspective, by stating the use of a XOR Gateway without the following mandatory use of a XOR Join Gateway as an error.

    There seem to be two different understandings of the handling of the XOR Join gateway. The Majority seems to state, that using this in general would be the best practise, whereas I think, that the logical aspect should be paramount. (Form follows function). That is why I was starting to research for an official explanation.

    So, could the OMG point out:
    A: Which possible Situation could logically justify the existance of this element?
    B: What a desired best practice in the use of this element would be?

Contradiction about process data input and output allowed connection with data association

  • Key: BPMN11-95
  • Status: open  
  • Source: Trisotech ( Mr. Denis Gagne)
  • Summary:

    Page 213 states the following restriction about process data input and incoming data association:

    • Data Inputs MAY have incoming Data Associations:
      • If the Data Input is directly contained by the top-level Process, it MUST not be the target of Data Associations within the underlying model. Only Data Inputs that are contained by Activities or Events MAY be the target of Data Associations in the model.

    Page 215 states the following restriction about process data output and outgoing data association:

    • Data Outputs MAY have outgoing DataAssociations.
      • If the Data Output is directly contained by the top-level Process, it MUST not be the source of Data Associations within the underlying model. Only Data Outputs that are contained by Activities or Events MAY be the target of Data Associations in the model.

    So according to those, a Process Data Input MUST NOT have incoming data association and a process Data Output MUST NOT have outgoing data association.

    But on page 225, the following is stated:

    In the case of a Start Event, the Data Inputs of the enclosing process are available as targets to the DataOutputAssociations of the Event. This way the Process Data Inputs can be filled using the elements that triggered the Start Event.

    In the case of an End Event, the Data Outputs of the enclosing process are available as sources to the DataInputAssociations of the Event. This way the resulting elements of the End Event can use the Process Data Outputs as sources.

    So according to those paragraphs, a process data input might have incoming data association if the source is a start event and a process data output might have outgoing data association if the target is an end event.

    Those exceptions should be written on page 213 and 215 to avoid confusion.

    In the metamodel, the common superclass of Event, Activity, Choreography Activity, and Gateway is FlowNode. Does that mean, Flow Object and Flow Node are synonyms? Or is Flow Object the graphical object and Flow Node the model element? Both words are used throughout the specification, e.g.

    Table 7.3 displays the BPMN Flow Objects and shows how these objects can connect to one another through Sequence Flows.

    Of the types of Flow Node, only Activities, Gateways, and Events can be the target [of a Sequence Flow].

    Does it serve any purpose to have different names for the two? I find it confusing.

    Suggestion
    Replace all occurrences of "Flow Object" with "Flow Node".

Inconsistent semantics of multiple none start events

  • Key: BPMN21-413
  • Status: open  
  • Source: oose Innovative Informatik eG ( Mr. Axel Scheithauer)
  • Summary:

    The specification says:

    10.5.2 Start Event All Flow Objects that do not have an incoming Sequence Flow SHALL be instantiated when the Process is instantiated.

    There are some exceptions to this rule, but they don't touch the following discussion. Since Events are Flow Objects, this applies also to Start Events: When the process with multiple Start Events is instantiated, all Start Events of this instance are instantiated (i.e. they get a token).

    Further down it says however:

    There MAY be multiple Start Events for a given Process level. Each Start Event is an independent Event. That is, a Process instance SHALL be generated when the Start Event is triggered.

    That means on instantiating a process, each Start Event gets instantiated, which in turn instantiates a new process. I don't think this was intended.

    In the same section the semantics for calling global processes is defined differently (without mentioning it as an exception to the above rule):

    If the Process is used as a global Process and there are multiple None Start Events, then when flow is transferred from the parent Process to the global Process, only one of the global Process’s Start Events will be triggered.

    So called global Processes are treated differently from Subprocesses (I know, somewhere else it is stated, that a Subprocess can only have a unique Start Event - a rule that is contradicted in the immediately following sentence). I think this is confusing.

    Suggestion
    Change the above sentence

    All Flow Objects that could have but do not have an incoming Sequence Flow SHALL be instantiated when the Process is instantiated.

    This way, multiple Start Events are always alternative. This would be in line with many other sections of the specification:

    13.2 Process Instantiation and Termination A Process is instantiated when one of its Start Events occurs. Each occurrence of a Start Event creates a new Process Instance [...] Note that two Start Events are alternative [...]

    and

    13.3.4 Sub-Process/Call Activity If the Sub-Process does not have incoming Sequence Flows but Start Events that are target of Sequence Flows from outside the Sub-Process, the Sub-Process is instantiated when one of these Start Events is reached by a token. Multiple such Start Events are alternative. [...]

Unclear how to add new Artifact Types

  • Key: BPMN21-410
  • Status: open  
  • Source: oose Innovative Informatik eG ( Mr. Axel Scheithauer)
  • Summary:

    The specification says about Extension:

    It provides a set of extension elements, which allows BPMN adopters to attach additional attributes and elements to standard and existing BPMN elements.

    In other words, extension can only add something to existing elements, but not create new element types.
    However about Artifacts it says:

    A modeler or modeling tool MAY extend a BPMN diagram and add new types of Artifacts to a Diagram.

    Given the extension mechanism, it is unclear, how new types of Artifacts can be added. And since the Metaclass Artifact is abstract, it is not possible to use the generic Artifact and extend it to create something resembling a new type. A modeler would always need to specify the concrete subclass, such as Group or TextAnnotation and thus inherit attributes and semantics he probably doesn't need.
    So either the sentence is wrong, or there is another extension mechanism, that needs some explanation here.

    This attribute is derived and the elements are found by looking at the diagram and determining, which elements are within the boundaries of the dashed box representing the Group. As far as I know, this is the only place in the specification, where the location of an element in the diagram is relevant for the semantics. I think there should be a more formal way.
    Further down the specification says:

    Groups are one way in which Categories of objects can be visually displayed on the diagram.

    If the only way to define a group is to show it in the diagram (as the first sentence implies), this sentence is wrong.

Adding this to the main specification would greatly improve the BPMN's applicability and usability.

Outgoing sequence flows from event gateways should allow conditional expressions

  • Source: Atom Software Pty Ltd ( Paul Hopkins)
  • Summary:

    Allow event-based gateways to have outgoing conditional flows. Section 10.6.6 of the BPMN specification v2.0.2 states that “The outgoing sequence flows of the event gateway must not have a conditional expression”. I suggest that this clause be changed because an initiating event-based gateway is an excellent way to model, for example, a menu, where not all items on a menu are available all the time (as they might depend upon user roles or the application’s state). With outgoing conditional flows from the event-based gateway this situation can be modelled easily. Of course modelling a menu is only one such scenario, and I appreciate that the conditions to be applied to the conditional flows could instead be applied to the events following the event-based gateway, but the use of conditional flows is simply a cleaner implementation.

Probable contradiction: Implicit compensation and Throwing Compensation Events

  • Key: BPMN21-403
  • Status: open  
  • Source: omninet.de ( Frank Munkert)
  • Summary:

    In table 10.88 "End Event Types", the table row with header "Compensation" contains this statement:
    "To be compensated, an Activity MUST have a boundary Compensation Event or contain a Compensation Event Sub-Process."
    The same applies to Table 10.89 "Intermediate Event Types in Normal Flow" on page 251.

    On page 234, however, there is this statement: "The compensation handler is either user defined or implicit."

    The two statements, taken together, would mean that an implicit compensation handler cannot be called by a Throwing Compensation Event.

    This probably is not intended.

    Either the concept of implicit compensation should be removed alltogether (which is not my preference), or alternatively the sentence
    "To be compensated, an Activity MUST have a boundary Compensation Event or contain a Compensation Event Sub-Process."
    should be changed like this:
    "To be compensated, an Activity MUST have a boundary Compensation Event or contain a Compensation Event Sub-Process, or the Activity must be a Sub-Process or a Call Activity calling a Process."
    because sub-processes and called processes always are implicitly compensable (unless the compensable attribute is set to false).

Define "Cancellation" more precisely

  • Summary:

    Chapter "10.5.1 Concepts" contains the following statement on page 234:
    "Cancellation will terminate all running Activities and compensate all successfully completed Activities in the Sub-
    Process it is applied to. If the Sub-Process is a Transaction, the Transaction is rolled back."

    The standard, however, is a little bit vague about what actually triggers cancellation.
    Here are just a few examples of scenarios in whose descriptions the standard applies the term "cancel":

    • Throwing Cancel Event
    • 'cancelRemainingInstances' attribute of Ad-Hoc Sub-Processes
    • 'completionCondition' attribute of Multi-Instance Activities
    • 'condition' attribute of ComplexBehaviorDefinitions
    • 'isInterrupting' attribute of Start Events in Event Sub-Processes
    • 'cancelActivity' attribute of boundary events

    Do all these scenarios trigger a cancellation in the sense of the above mentioned statement?
    This should be explained more precisely in the standard.

    Furthermore, on page 301, there is this statement:
    "Cancellation in turn can result in compensation of already successfully completed
    portions of an active Activity, in case of a Sub-Process."

    Why does the statement use "can result" instead of e.g. "always results"?
    The standard should describe precisely under which circumstances cancellation results in compensation, and the circumstances under which cancellation does not result in compensation.

    The last cited sentence does not take into consideration that the outgoing sequence flows might have conditions. Therefore, the statement "behaves like an implicit Parallel Gateway" is not entirely correct.

    Suggestion for a revised version of the last sentence:

Clarification needed regarding converging exclusive gateway and slash marker

    On page 290, in section "10.6.2 Exclusive Gateway", there is the following text:
    "A converging Exclusive Gateway is used to merge alternative paths. Each incoming Sequence Flow token is routed
    to the outgoing Sequence Flow without synchronization."

    On page 435, in section "13.4.2 Exclusive Gateway (Exclusive Decision (data-based) and Exclusive Merge)", there is the following text in the table:
    "Exception Issues - The exclusive gateway throws an exception in case all conditions evaluate to false and a default flow has not been specified."

    I.e. according to the table, in order not to throw an exception, a converging exclusive gateway would need to have a default flow marker on its single outgoing sequence flow. This seems to be a contradiction to the description in section 10.6.2. Therefore, this should be clarified in both sections, e.g. using a sentence like this: "The single outgoing sequence flow of a merging exclusive gateway is implicitly assumed to be the default sequence flow. A slash marker MAY be shown in diagrams for such sequence flows."

    Without such a clarification, BPMN process diagrams where an outgoing sequence flow of a converging exclusive gateway has no slash marker would be wrong. Since those diagrams are very common (e.g. OMG's "BPMN 2.0 by Example", v1.0, page 36), it should be explicitly mentioned that omitting the slash marker is allowed.

Task Description -- Internal Conflict

  • Summary:

    Sect 10.3.3 states, "A Task is used when the work in the Process cannot be broken down to a finer level of detail."

    However, the task definition in the glossary states, "A Task is used when the work in the Process is not broken down to a finer level of Process Model detail."

    The phrase, "cannot be broken down" is much different than the phrase, " is not broken down". The latter suggests that an activity could be broken down further, but was not.

    The glossary definition is correct since a task can often be broken down into tiny actions (e.g., Click the left mouse button), but a person modeling the process may choose not to model to that low a level. Thus, a task is the lowest level shown on a diagram, but may not necessarily be the lowest possible level.

    Recommend that the sentence in Sect 10.3.3 be changed to be consistent with the one in the glossary. As an option, you also may wish to make that statement, "Any conflicts between the glossary and other parts of the specification, the glossary takes precedence."

    Similarly, the same table describes the "outputSetWithWhileExecuting" attribute with "Each OutputSet that uses this DataInput can determine if the Activity can produce this DataOutput while executing. This attribute lists those OutputSets." Same correction applies.

The behaviors of these two gateways are different, but they look the same. Suggestion is that the first AND gateway, that starts the parallel split have a thin line, while the gateway at the end which actually waits for multiple inputs will have a thick line. This corresponds to the thin and thick lines around start and end nodes.

Sequencing rule for Choreography activities causes ambiguous execution semantics?

  • Key: BPMN21-362
  • Legacy Issue Number: 19318
  • Status: open  
  • Source: planet.nl ( kwantes)
  • Summary:

    (p.336 The basic rule of Choreography Activity sequencing is this: ?The Initiator of a Choreography Activity MUST have been involved (as Initiator or Receiver) in the previous Choreography Activity.
    As far as I can tell this rule seems to imply some ambiguity as to the execution semantics of the Choreography diagram. To explain this, I give an example of two different Choreography designs of one and the same collaboration:
    Design version 1 involves 5 message exchanges , three choreography activities A, B and C and 4 participants, 1,2,3 and 4. The activities are listed below in execution order :
    1. Activity A :
    1.1. 1 sends message to 2
    2. Activity B:
    2.1. 3 sends message to 2
    2.2. 2 sends message to 4
    2.3. 4 returns message to 2
    3. Activity C:
    3.1. 2 sends confirmation of message sent by 1 (in 1.1.)

    Design version 2 involves the same 5 message exchanges into two choreography activities A and B involving the same 4 participants listed below in execution order:
    1. Activity A :
    1.1. 1 sends message to 2
    1.2. 2 sends confirmation of message sent by 1 (in 1.1., but after receiving message sent by 4 in 2.3.)
    2. Activity B:
    2.1. 3 sends message to 2
    2.2. 2 sends message to 4
    2.3. 4 returns message to 2

    {Question 1: are observations below correct or not? }

    Both designs seem to meet the criterion mentioned in the BPMN standard specification mentioned in the first paragraph above. The second has the advantage that the message exchanges 1.1. and 1.2. which are logically strongly related are combined in one activity. But the execution semantics implied by the two designs are quite different. The first design implies that an activity can only start after completion of the previous activity. The second design implies that an activity can only start after the previous activity has started. The basic rule of Choreography Activity sequencing seems to allow both interpretations.

    {Question 2: is the issue below a valid point in your opinion ? }

    If the first interpretation is chosen, then there is the question what is meant by “completion”. That might mean different things for the sender and receiver of the last message exchanged. The sender is finished when he sent the last message. The receiver might first need to do some internal processing before it is completed. So this interpretation runs the risk of being ambiguous.

    {Question 3: can you please comment on this ? }

    The second interpretation could make it less straightforward to understand the ordering of activities from the diagram. On the other hand it does allow more room for combining logically related message exchanges in one activity (as 1.1. and 1.2. in activity A in the second interpretation). This raises the general question on how the Choreography diagrams and Conversation diagrams are conceptually related. They seem to be addressing a similar requirement for expressing communication between Business actors, but it is unclear how they are or should be related.

Allowable start events for event sub-process inconsistently defined

  • Key: BPMN21-359
  • Legacy Issue Number: 19166
  • Status: open  
  • Source: outlook.com ( Devin Fensterheim)
  • Summary:

    There is an apparent conflict in the specification concerning the permissible Start Event types for an Event Sub-Process.

    On Page 174, the specification states: "The Start Event of an Event Sub-Process MUST have a defined trigger. The Start Event trigger (EventDefinition) MUST be from the following types: Message, Error, Escalation, Compensation, Conditional, Signal, and Multiple." This enumeration excludes the Timer and Parallel event types.

    This specification appears inconsistent with the restriction on Page 241, which additionally allows Timer and Parallel event types for the Start Event: "A Start Event can also initiate an inline Event Sub-Process (see page 174). In that case, the same Event types as for boundary Events are allowed (see Table 10.86), namely: Message, Timer, Escalation, Error, Compensation, Conditional, Signal, Multiple, and Parallel."

    It is consequently unclear whether Timer and Parallel events may be the Start Event in an Event Sub-Process.

    The specification defines that the type for start-events of sub-processes can only be the none-type... However, the allowed number of start events for sub-processes is not mentioned... at least I couldn't find it throughout the whole specification.

    As far as I understood BPMN, two none-typed start-events in sub-processes would not make sense but the point should clearly be described in a specification.

  • Legacy Issue Number: 16904

  • Summary:

    Page 180 (PDF 210) states:

    Whereas page 305 (PDF 335) states:
    'If no error Event Sub-Process is specified for a particular Sub-Process and a particular error, the default behavior is to automatically call compensation for all contained Activities of that Sub-Process if that error is thrown, ensuring the behavior for auditing and monitoring.'

    These statements seem contradicting to me and therefore I'd like to get a clarification on the following questions:

    1. Is compensation allways triggered automatically upon uncaught errors?
    2. Is there a difference between compensation of a Transaction Sub-Process and any other Sub-Process?

Extend BPMN with a element that subclasses an existing BPMN element

  • Key: BPMN21-353
  • Legacy Issue Number: 18787
  • Status: open  
  • Source: Perceptive Software ( Mark van Roermund)
  • Summary:

    'Section 8.2.3 Extensibility' on page 57 of the BPMN 2.0 specification states:

    "The BPMN metamodel is aimed to be extensible. This allows BPMN adopters to extend the specified metamodel in a way that allows them to be still BPMN-compliant."

    On page 58 it is stated that:

    "Every BPMN element which subclasses the BPMN BaseElement can be extended by additional attributes. This works by associating a BPMN element with an ExtensionDefinition, which was defined at the BPMN model definitions level (element Definitions)."

    Question:
    Is it possible to extend BPMN with an element that subclasses an existing BPMN element?

    For example, is it possible to extend BPMN with a new task element that subclasses the BPMN Task, similar to how e.g. a ManualTask or UserTask subclasses the BPMN Task? If this is possible, could you provide an example?

Suspected definition error in DataObject.isCollection

  • Summary:

    In Table 10.52 the description of DataObject.IsCollection reads "If an itemDefinition is referenced, then this attribute MUST have the same value as the IsCollection attribute of the referenced itemDefinition".

    This description prevents BPMN from defining a collection of DataObjects on a single Item Aware Element referred to by an Item Definition. Therefore, if I wish to model an individual item X and a collection of item X they need to reference different item definitions - surely this is not the intent.

    I propose rewording this sentence to read "If a referenced itemDefinitions isCollection attribute is set to true, then this attribute MUST also be set to true".

    I don't know if there is a flow-on effect to other areas of the documentation.

Revision & clarification for interruption of looping / multi-instance sub-processes

  • Key: BPMN21-333
  • Legacy Issue Number: 17528
  • Status: open  
  • Source: gmail.com ( Andre Gomes da Silva)
  • Summary:

    In Table 10.88 ­ End Event Types (page 248) it’s written:

    “Terminate ­ This type of End indicates that all Activities in the Process should be immediately ended. This includes all instances of multi-instances.”

    However, in 13.4.6 ­ End Events (page 443) it’s written:

    “For a ‘terminate’ End Event, the Sub-Process is abnormally terminated. In case of a multi-instance Sub-Process, only the affected instance is terminated—no other ongoing Sub-Process instances or higher-level Sub-Process or Process instances are affected.”

    So, it seems to be a contradiction: first it’s written all instances of multi-instances are terminated, but after it’s written only one instance is terminated.

    CLARIFICATION =============

    Since the contradiction mentioned above, I think it’s also needed to clarify how many instances are terminated when a multi-instance Sub-Process is interrupted via Boundary Event or via Event Sub-Process.

    The specification also does not mention how the interruption of a looping Sub-Process should be handled: is only the current iteration interrupted (like the “continue” statement in software programming), or the whole loop is interrupted (like the “break” statement in software programming)? So, it’s needed to clarify this behavior for interruptions triggered via terminate End Event, Boundary Events and Event Sub-Processes.

    This issue is related to Issue #14824.

Use XPath 2.0 as default expression language instead of XPath 1.0

  • Key: BPMN21-316
  • Legacy Issue Number: 16877
  • Status: open  
  • Source: University of Bamberg ( JöLenhard)
  • Summary:

    XPath 1.0 is the default expression language in BPMN 2.0. Instead of XPath 1.0, the default expression language should be XPath 2.0 which is a W3C Recommendation since 14 December 2010 (and I assume that is why it has not made it into BPMN 2.0).

    A major problem with XPath 1.0 is its limited set of functions. For instance, XPath 1.0 does not provide any time-related functions. Consequently, it is impossible to get the current system time in an expression, which might be necessary in Timer Events, without proprietary extensions to the standard. This harms portability of process models and is especially relevant for Process Execution Conformance. XPath 2.0 provides such functions and the time-related data types used in both, BPMN 2.0 and XPath 2.0, are identical (ISO-8601).

    This change might affect several parts of the specification:
    In section 10.3.3 The usage of XPath as expression language in BPMN 2.0 is discussed. There, several additional XPath-functions are defined, mentioning deficiencies in XPath 1.0. These functions should be redefined with XPath 2.0.
    Section 14 Mapping BPMN Models to BPEL might also require changes. XPath 1.0 is the default language required by BPEL 2.0 and XPath 2.0 functions that are not present in XPath 1.0 cannot be mapped as easily.

    I would strongly recommend for BPMN 2.0 to require the support for XPath 2.0 instead of XPath 1.0 as default expression language.

XML Schema: Usage of xsd:anyAttribute instead of xsd:attribute

  • Key: BPMN21-315
  • Legacy Issue Number: 16632
  • Status: open  
  • Source: IHK Gesellschaft fuer Informationsverarbeitung mbH ( Sven Joerges)
  • Summary:

    <xsd:anyAttribute name="exporter" type="xsd:ID"/>
    <xsd:anyAttribute name="exporterVersion" type="xsd:ID"/>

    As the usage of the "name" attribute in combination with the "xsd:anyAttribute" element makes no sense, those lines should be changed to:

    <xsd:attribute name="exporter" type="xsd:ID"/>
    <xsd:attribute name="exporterVersion" type="xsd:ID"/>

    As the XSD-Files given at www.omg.org/spec/BPMN/2.0/ also use "xsd:attribute" for those lines, I suppose this is just a copy&paste error in the specification document.

Incomming sequence flow at start event

  • Key: BPMN21-326
  • Legacy Issue Number: 17047
  • Status: open  
  • Source: University of Applied Sciences Dresden ( Michael Gruenert)
  • Summary:

    An interesting rule (page 245):
    ‘A Start Event MUST NOT be a target for Sequence Flows; it MUST NOT have incoming Sequence Flows. An exception to this is when a Start Event is used in an Expanded Sub-Process and is attached to the boundary of that Sub-Process. In this case, a Sequence Flow from the higher-level Process MAY connect to that Start Event in lieu of connecting to the actual boundary of the Sub-Process.’

    I never found a tool who implements this rule. On page 261 a ‘Boundary Start event’ does not exist. Only Intermediate Events are of type ‘boundary’ (interrupting/non-interrupting). Or interrupting/non-interrupting Start Events for an Event-Sub-Process (but they are not of type ‘boundary’).

    -> is it ok to remove this exception?

    Description:

    * Section 2: Table 2.3, note ‘a’ [page 7]: Should be “Multiple incoming connections…” [incoming vs. outgoing]

    • Section 7: Tables 7.1 and 7.2 (and others?): Missing 'a' in front of 'company' in "An Activity is a generic term for work that company performs"
    • Section 7: Table 7.2, Activity [p. 32]: The spec seems to consistently use the spelling “Sub-Process” for sub-processes. Merriam-Webster indicates that “subprocess” is the correct form of the word (i.e. that sub is simply a prefix) and does not offer a hyphenated alternative (even though Microsoft Word complains ‘subprocess’ is misspelled
    • Table 7.2, Choreography Task [p. 32]: Missing "or more" in "Each Choreography Task involves two (2) Participants", as they can specify more than 2 Participants.
    • Table 7.2 Conditional Flow [p.35]: Typo; should be ‘is’ vs. ‘are’ in "A Sequence Flow can have a condition Expression that are evaluated" (or should be "Expressions that are").
    • Table 7.2 Compensation Association [p. 35]: The activity that is the target of the Compensation Association is missing the compensation indicator.
    • Section 8.3.1 Artifacts, Text Annotation [p. 71]: May contradict itself on open rectangle. Says “A Text Annotation is an open rectangle that MUST be drawn with a solid single line (as seen in Figure 8.16).” and then “text associated with the Annotation can be placed within the bounds of the open rectangle.” Isn't that "...MUST be placed within"? Why MUST you draw the open rectangle if text doesn't go within it, per Figure 8.16?
    • Section 10.2 Activities, [p.153]: completionQuantity says "This number of tokens will be sent done any..." and the 'done' should be 'down'.
    • Section 10.2.3 Tasks, Receive Task [p. 161]: "Once the Message has been received, the Task is completed." Is this worded correctly? If this Task doesn't do anything after the Message is received, then why use it instead of a Receive (Catch) Message Event?
    • Section 10.2.5 Subprocesses, page 177: The following is missing Timer (at a minimum; also missing Parallel Multiple?): “The Start Event trigger (EventDefinition) MUST be from the following types..."
    • Section 10.2.5 Subprocesses, page 177, Figure 10.30 is incorrect; it does not show the start event in upper-left corner like text says.
    • Section 10.2.8: pages 190 & 191, Figures 10.47, 10.48, and 10.49 contradict Table 12.8 on page 382 & 383 on the location of the multi-instance indicator (marker) for Collapsed Subprocesses. I assume Table 12.8 is correct.
    • Section 10.4: page 233: The word 'trigger' should be 'result' in the following sentence in list item 2: "The throwing of a trigger MAY be..." (Items 1 & 2 say "Events that catch a trigger" and "Events that throw a Result." So triggers are caught and results are thrown, correct?
    • Section 10.4.6, page 276, Figure 10.98: An Intermediate multiple event marker is used for a start event-based gateway, and it should be a start event marker (single line vs. double on the Event within the Gateway).
    • Section 10.4.6, page 277: The following seems to be missing Escalation Events at a minimum: “...or by running an Event Handler without canceling the Activity (only for Message, Signal, Timer and Conditional Events, not for Error Events).”

    * Section 10.8, page 309: Figure 10.1 was updated, but the references to activity names in the Figure were not updated in the first and second paragraphs of Section 10.8. For example “…in Figure 10.1 might execute or perform an extra Activity between Task “Receive Issue List” and Task “Review Issue List.””

    • Section 11.4.1: Choreography Task [p. 327, 332]: The text is unclear about whether Participants can be multi-instance sequential, but I believe they can. As such, the language on page 327 of “The marker for a Choreography Task that is multi-instance MUST be a set of three vertical lines” and

    on page 332 of “The marker for a Sub-Choreography that is multi-instance MUST be a set of three vertical lines” seems incorrect and too limiting. If multi-instance sequential can be used, then three horizontal lines are also allowed (as is the 'loopback' repeat?).

    • Section 13.2.2 Activity [p. 429]: The fifth bullet says "(proposed for BPMN 2.0)" when this is the final spec, and non-interrupting EVent Handlers are part of the spec. This should be removed.

BPMN 2.0 Choreography issues page 327 of dtc/2010-06-05

  • Key: BPMN21-306
  • Legacy Issue Number: 16547
  • Status: open  
  • Source: Anonymous
  • Summary:

    Page 327 of /dtc/2010-06-05/ runs as follows (emphasis in the last
    sentence added):

    “To leverage the familiarity of flow charting types of Process
    models, BPMN Choreographies also have “activities” that are ordered
    by Sequence Flows. These “activities” consist of one (1) or more
    interactions between Participants. These interactions are often
    described as being message exchange patterns (MEPs). A MEP is the
    atomic unit (“Activity”) of a Choreography.

    Some MEPs involve a single Message (e.g., a “Customer” requests an
    “Order” from a “Supplier”). Other MEPs will involve two (2) Messages
    in a request and response format (e.g., a “Supplier” request a
    “Credit Rating” from a “Financial Institution,” who then returns the
    “Credit Rating” to the “Supplier”). There can be even more complex
    MEPs that involve error Messages, for example.”

    This wording may result confusing to practitioners. First of all,
    there is no way in BPMN 2.0 Choreographies to mark a message as an
    “error message”. What the specification seems to hint at is that
    some of the messages in the choreography may deliver information
    over errors. However, since BPMN 2.0 Choreographies (and, more
    generally, BPMN 2.0 as a whole) does not differentiate among the
    possible “typologies” of messages (e.g. error, acknowledgement,
    invocation, or response), there is no immediate way to map WSDL
    1.1/2.0 MEPs to single Choreography Taskswithout losing some
    information (e.g. the distinction between output messages and fault
    messages). Even using the structureRefof the message(see e.g. Page 7
    of /dtc/2010-06-05/) to point to a WSDL 1.1/2.0 message, this would
    provide no information about what “type” of message it is. In fact,
    in WSDL 1.1/2.0 a message is “labelled” as input, output or fault
    only in the WSDL operations, so much that a given WSDL message
    could, for example, be input in one operation and a fault in another.

    Secondly, despite the fact that the text mentions Choreography
    Activities as the realization of MEPs (i.e. also
    Sub-choreographies), the reference to MEPs as atomic units sounds
    intuitively related to Choreography Tasks. Given the fact that it is
    not possible to (1) specify error messages and (2) specify the
    sequencing in a single Choreography Taskfor more than two messages,
    a single Choreography Taskallows the specification of only the WSDL
    1.1 “one-way messaging” and “notification” MEPs. In fact, the
    specification of “request/reply” and “solicit/response” MEPs is not
    possible because their faults cannot be represented in the same
    Choreography Tasktogether with the input and output messages.

    To clarify this issues, the specification should address clearly and
    in detail the relation between BPMN 2.0 Choreographies and MEPs in
    WSDL 1.1 and WSDL 2.0, in particular with relation to the
    granularity of the MEPs (Choreography Task-level, Sub-choreography
    level, etc.). Moreover, it is still an open issue how to map WSDL
    2.0 Complex MEPs to BPMN 2.0 Choreographies.

  • Summary:

    N.B. In the reminder /dtc/2010-06-05 /is the BPMN 2.0 specification.

    ------ ISSUE START ------
    Page 339 of /dtc/2010-06-05/ reads as follows:

    “There are situations when a Participant for a Choreography Task is
    actually a multi-instance Participant. A multi-instance Participant
    represents a situation where there are more than one possible
    related Participants (PartnerRoles/ PartnerEntities) that might be
    involved in the Choreography. For example, in a Choreography that
    involves the shipping of a product, there can be more than one type
    of shipper used, depending on the destination.”

    Page 344 of /dtc/2010-06-05/ reads almost verbatim, but referring to
    multi-instance participants in Sub-choreographies:

    “There are situations when a Participant for a Sub-Choreography is
    actually a multi-instance Participant. A multi-instance Participant
    represents a situation where there are more than one possible
    related Participants (PartnerRoles/ PartnerEntities) that can be
    involved in the Choreography. For example, in a Choreography that
    involves the shipping of a product, there can be more than one type
    of shipper used, depending on the destination.”

    First of all, the above wordings are unclear with respect to which
    of the following two cases applies at run-time with multi-instance
    participants:

    1. Exactly one partner entity (as defined on Page 117 of
    /dtc/2010-06-05/) out of many possible ones during the enactment
    of the choreography.
    2. One or more partner entities partake the choreography enactment.

    We could not find in the /dtc/2010-06-05/any wording that clarifies
    which of the two possible meanings is the correct one. We assume (2)
    for consistency with the Orchestration part of the specification.
    However, having a multi-instance participant resolve to multiple
    partner entities during the enactment raises several serious issues:

    • Multi-instance recipient participants in a choreography task
      violate the assumption that each choreography task involves
      exactlytwo partner entities, which is a fundamental assumption
      for the specification of Message Exchange Patterns (MEPs) in
      Choreography Tasks.
    • Similarly to the previous case: how to deal with Choreography
      Task senders that are multi-instance participants? How many
      initiating messages are actually sent?

    Even more complicated issues arise from multi-instance participants
    in terms of the enforceability of choreographies. For example, if
    the partner entities that resolve a given multi-instance participant
    are decided at enactment time, how are the other partner entities
    supposed to know (and therefore be able to deliver messages to them)?

    It is our opinion that multi-instance participantsis a complicated
    construct to deal with in Choreographies, and should be thoroughly
    re-considered (possibly leading to its elimination from the
    specification).

meta-model doesn't provide way to serialize intermediate catch events attached to participant bands of choreography task

  • Key: BPMN21-308
  • Legacy Issue Number: 16549
  • Status: open  
  • Source: IAAS, University of Stuttgart ( Michele Mancioppi)
  • Summary:

    On pp. 341~343 the specification details some intermediate catch events that can be attached to activity boundaries, namely Message, Timer, Cancel, Compensation, Conditional, Signal and Multiple. This is similar to attaching events to activities in Process diagrams. The meta-model supports attaching of events to activity boundaries in Processes through the BoundaryEvent element. However, no similar element is available for Choreography Activities. Instances of BoundaryEvent obviously cannot be used (because ChoreographyActivity does not extend Activity). Therefore a new Class should be added. This class (called e.g. ChoreographyBoundaryEvent) should (1) have a reference to the ChoreographyActivity to which the event is attached, and (2) depending on the type of event, specify to which of the ParticipantBands the event is attached. This is necessary because some events, namely Message, Cancel and Compensation are "local" (i.e. visible) to only one of the Participants involved in the ChoreographyActivity. The specification should clearly state in which cases this reference to a Participant is compulsory, and in which cases optional. For example, it might be optional in the case of Signal events, to symbolize that the event is trigger by the reception of the signal by one particular participants (which is different than the "firing" of the signal, given the fact that the specification does not seem to require signals to be "immediately" received, but just "eventually" received by the participants).

BPMN 2.0 Choreography issues page 338 of dtc/2010-06-05 about Sub-choreographics

  • Key: BPMN21-307
  • Legacy Issue Number: 16548
  • Status: open  
  • Source: Anonymous
  • Summary:

    On Page 338 of /dtc/2010-06-05/, about Sub-choreographies:

    “The Participant Band of the Participant that does not initiate the
    interaction MUST be shaded with a light fill.”

    This wording does not cover some corner cases. Consider the example
    depicted in the attached image Example Issue Initiating Participant
    in Sub-Choreographies.png. In the choreography above it is unknown
    until the enactment of Task 1which participant is the initiator of
    Sub-choreography 1. But this is only the symptom of a wider-reaching
    problem. When there is no choreography task that dominates of all
    the others (or worse, there is a race condition!), and the various
    choreography tasks that may be executed as first have different
    initiators, modelers have no way to pick which participant is marked
    as the initiator of the sub-choreographies.

    The same issue with initiators of sub-choreographies affects also
    the messages sent by them. In fact, Page 93 of /dtc/2010-06-05/reads:

    “Any Message sent by the non-initiating Participant or
    Sub-Choreography MUST be shaded with a light fill.”

    We propose two possible, mutually exclusive solutions:

    1. Additional constraints are specified for choreographies so that
    no such corner case can occur. However, this is very likely to
    result in not being able to model with BPMN 2.0 choreographies
    some inter-organizational processes that can instead be modeled
    with BPMN 2.0 Orchestrations.
    2. Drop the differentiation between initiator and non-initiator
    participants in sub-choreographies. We see no real shortcoming
    resulting from this approach. In particular, with respect to the
    enactability of choreographies, knowing which participant is the
    first to act in a sub-choreography gives no guarantees as to the
    fact that the same participant will also be involved in the
    “last” choreography activities to be executed in that
    sub-choreography. Therefore, we can extract no useful
    information from it with respect to the enactability of what
    follows that sub-choreography. This is particularly true in the
    case of collapsed sub-choreographies.

Unclear introduction of the concept of MEP

  • Key: BPMN21-310
  • Legacy Issue Number: 16551
  • Status: open  
  • Source: IAAS, University of Stuttgart ( Michele Mancioppi)
  • Summary:

    Page 315 reports the following text on MEPs:

    “To leverage the familiarity of flow charting types of Process models, BPMN Choreographies also have “activities” that are ordered by Sequence Flows. These “activities” consist of one (1) or more interactions between Participants. These interactions are often described as being message exchange patterns (MEPs). A MEP is the atomic unit (“Activity”) of a Choreography.

    Some MEPs involve a single Message (e.g., a “Customer” requests an “Order” from a “Supplier”). Other MEPs will involve two (2) Messages in a request and response format (e.g., a “Supplier” request a “Credit Rating” from a “Financial Institution,” who then returns the “Credit Rating” to the “Supplier”). There can be even more complex MEPs that involve error Messages, for example.”

    This wording may result confusing to practitioners for the following reasons.

    First of all, there is no way in BPMN 2.0 Choreographies to mark a message as an “error message”. What the specification seems to hint at is that some of the messages in the choreography may deliver information over errors. However, since BPMN 2.0 Choreographies (and, more generally, BPMN 2.0 as a whole) does not differentiate among the possible “typologies” of messages (e.g. error, acknowledgement, invocation, or response), there is no immediate way to map WSDL 1.1/2.0 MEPs to single Choreography Tasks without losing some information (e.g. the distinction between output messages and fault messages). Even using the structureRef of the message (see e.g. Page 7 of dtc/2010-06-05) to point to a WSDL 1.1/2.0 message, this would provide no information about what “type” of message it is. In fact, in WSDL 1.1/2.0 a message is “labelled” as input, output or fault only in the WSDL operations, so much that a given WSDL message could, for example, be input in one operation and a fault in another.

    Secondly, despite the fact that the text mentions Choreography Activities as the realization of MEPs (i.e. also Sub-choreographies), the reference to MEPs as atomic units sounds intuitively related to Choreography Tasks. Given the fact that it is not possible to (1) specify error messages and (2) specify the sequencing in a single Choreography Task of more than two messages, a single Choreography Task allows the specification of only the WSDL 1.1 “one-way messaging” and “notification” MEPs. In fact, the specification of “request/reply” and “solicit/response” MEPs is not possible because their faults cannot be represented in the same Choreography Task alongside the input and output messages.

    To clarify this issues, the specification should address clearly and in detail the relation between BPMN 2.0 Choreographies and MEPs in WSDL 1.1 and WSDL 2.0, in particular with relation to the granularity of the MEPs (Choreography Task-level, Sub-choreography level, etc.).

    Additionally, it might be beneficial to for the sake of clarity to explicitly that it is outside the scope of ChoreographyTasks to be able to map entire WSDL 2.0 Complex MEPs, but that, instead, they have to be realized by multiple choreography tasks appropriately sequenced.

Meaning of 'behavior' attribute on MultiInstanceLoopCharacteristics quite confusing

  • Key: BPMN21-276
  • Legacy Issue Number: 15911
  • Status: open  
  • Source: Fraunhofer FOKUS ( Mr. Marc-Florian Wendland)
  • Summary:

    The meaning of the 'behavior' attribute on the MultiInstanceLoopCharacteristics is quite confusing. It is told that:

    • 'None' should throw an event on each instance,
    • 'All' should throw no event at all

    It seems that None and All meaning have been swapped.

    I also think that oneBehaviorEventRef and noneBehaviorEventRef can be merged as they are exclusive, they will never both be filled.

    Another question: what Event will own (composition relationship) the EventDefinition that is referenced by oneBehaviorEventRef or noneBehaviorEventRef ?
    As far as I understood, an EventDefinition can be owned only by an Event.

    My proposed solution:
    ---------------------
    1) Rewrite behavior: MultiInstanceBehavior meaning as following:

    behavior: MultiInstanceBehavior =
    all

    { None | First | Each | Complex}

    :
    -----------------------------------------
    The attribute behavior acts as a shortcut for specifying when events SHALL be thrown
    from an Activity instance that is about to complete. It can assume val-
    ues of None, One, All, and Complex, resulting in the following behav-
    ior:
    • None: no Event is ever thrown; a token is produced after completion
    of all instances
    • First: the EventDefinition referenced through the oneEvent
    association will be thrown upon the first instance completing;
    • Each: the EventDefinition which is associated through the
    noneEvent association will be thrown for each instance
    completing;
    • Complex: the complexBehaviorDefinitions are consulted to
    determine if and which Events to throw.

    For the behaviors of First and Each, a default
    SignalEventDefinition will be thrown which automatically carries
    the current runtime attributes of the MI Activity.
    Any thrown Events can be caught by boundary Events on the Multi-
    Instance Activity.

    3) Change oneBehaviorEventRef and noneBehaviorEventRef composition relationships
    Unless an answer is provided to the referred event definition ownership.

    2) Change the type of oneBehaviorEventRef and noneBehaviorEventRef to ThrowEvent
    Unless an answer is provided to the referred event definition ownership.

    4) Merge oneBehaviorEventRef and noneBehaviorEventRef into 'behaviorEventRef'

Subclasses of Interaction Node (Task vs. Activity)

    The question now is, whether Task or Activity should be the subclass of Interaction Node.

    Suggestion: The Message Flow Connection Rules on page 44 specify that Message Flows can also connect to Sub-Processes. Therefore, I think it is necessary to define that Activity is a subclass of InteractionNode.
