    Replace section 7.5. Evidence Metamodel with the following:
    7.5. Precise statements related to evidence
    In the simplest form, evidence consists of a collection of documents or records that provide evidentiary
    support to a set of claims. These claims are called subject claims, as the are made by an argument related to
    some selected subject area. Subject claims are different from evidence claims, which are the assertions
    about the evidence items that help establish the exact nature of the evidentiary support they provide to the
    subject claims in a clear, comprehensive and defensible way. Evidence claims can be reused as opposed to
    subject claims and arguments, which are specific to each subject area for which an assurance case is
    developed. Thus the SACM Evidence Metamodel defines the evidence vocabulary for constructing precise
    statements related to evidence. Evidence vocabulary is reused in every argument for various diverse subject
    areas.
    The Evidence Metamodel defines an interchange format for evidence (XSD schema defined through the
    application of XMI rules defined by MOF and XMI specifications) in which each evidence element,
    including claims about evidence, is represented by a specific XML tags. The evidence interchange format is
    then utilized to exchange bodies of evidence related to specific projects that require argumentation, for
    example, in presenting an assurance case. describing evidence-related efforts, including
    Collection of evidence
    Management of evidence
    Interpretation of evidence
    Evaluation of evidence
    Collection of Evidence includes activities of identifying evidence items, and recording various information
    about them, including their origin, timing and custody. Evidence Metamodel defines precise statements
    related to the pedigree of an evidence item, including evidence collection method or tool used.
    The primary items of evidence are Documents, Records, Assertions and Objects. Documents may have
    Properties that are characteristics independent of an assurance case being developed.
    Properties in the Evidence Metamodel include the following:
    Fundamental characteristics of Documents, for example
    Media of document
    Language of document
    Security classification of document
    Quality of Documents, for example
    Primary or secondary document
    Original or derived document
    Consistency
    Completeness
    Accuracy
    Management of Evidence compliments evidence collection activities with some planning and tracking
    activities. Important to the management of evidence is the set of Project Elements, including an Evidence
    Container, for grouping evidence items and assertions, as well as several elements for planning
    management collection Activities, including their dependencies, objectives, input and output data, and the
    evidence requests, which are the placeholders for evidence items that are being planned to be obtained.
    Combined with the evidence events, provenance, custody and timing clauses, these project elements are
    powerful enough to support management of evidence-related efforts and interchange of the relevant
    managerial data as part of evidence packages.
    Provenance of Evidence Elements, for example
    Who created
    Who approved
    Who owns
    Custody of Evidence Elements, for example
    Where the element was aquired
    Where the element is located
    Who is the custodian of the element
    Timing of Evidence Elements, for example
    When the element was created or acquired
    Effective Time of an assertion
    Interpretation of Evidence includes activities of assigning meaning to documents (what a document is,
    what claims does it make, etc). Interpretation of evidence is an important step in legal community, when a
    physical object is submitted as evidence.
    The following assertions are made to establish the meaning of evidence items.
    Meaning of Documents, for example
    Definition
    Meaning
    Scope
    Characteristics
    Evaluation of Evidence includes the activities of making certain assertions about evidence items and their
    relation to subject claims.
    Evidence Assertions are defined within the Evidence Metamodel and include the following categories: Quality Attributes of Evidentiary Support
    Direct or indirect
    Relevance
    Confidence
    Strength
    Significance
    Nature of the Evidentiary support
    Supports
    Challenges
    Observations and Resolutions
    The entire evidence package needs to be evaluated
    Relations between Evidence Items need to satisfy one of the well-defined “Standards of proof,” such as
    Clean and Convincing Evidence (CCE)
    Preponderance of evidence (POE)
    Resolved Counter Evidence (RCE), often used in the field of Genealogy as the Genealogical Proof
    Standard
    Beyond the reasonable doubt (BRD)

    This part of the Strucutred Assurance Case Metamodel defines the normative SACM Evidence Metamodel.
    SACM Evidence Metamodel consists of 18 class diagrams. SACM Evidence Metamodel is delivered as a
    single UML subpackage ‘Evidence’ of SACM.
    The SACM Evidence Metamodel consists of the following logical parts:
    Evidence Items
    Formal Elements
    Evidence Assertions
    Administration
    The Evidence Items part defines the physical evidence, provided in the form of documents, records and
    sometimes other material exhibits. The Formal Elements part defines the logical assertions, provided in
    the form of individual propositions. These propositions use an external vocabulary related to the subject
    area for which an argument is being provided. The Formal Elements part defines a subset of an OMG
    Semantics of Business Vocabularies and Business Rules (SBVR) fact model in the form of atomic
    formulations based on fact types with role bindings to individual concepts. SBVR is not used directly
    because of the semantic differences between fact models in linguistic models as they are defined in SBVR,
    conceptual models and “asserted fact models” involved in evidence collection and evaluation. Formal
    Elements represent a conceptual model underlying the entire assurance case. Evidence Assertions part
    defines various statements that can be made about the evidence items, such as documents, records and
    exhibits, and their relations to the subject area claims. Evidence Assertions includes statements that are
    related to various esential properties of evidence items. A large group of statements are the so-called
    evidence evaluations, including assertions of the evidentiary support (relations between evidence items and
    the subject area claims), assertions related to the interpretation of physical evidence and document,
    assertions about the conflicts in evidenctiay support and resolutions of these conflicts. Other statements are
    assertions related to provenance, custody and timing of the evidence items and evidence evaluations. The
    last group of statements qualify the evidentiary support that evidence items confer on the subject area
    claims. The Administration part defines an EvidenceContainer element which organizes individual
    evidence items and evaluations into a package that becomes a unit of exchange. The Administrative part
    also provides several means for managing evidence collection projects.

    Add Figure Administration to chapter 8 SACM Assurance Case as follows: << diagram on p 117 of ptc/2012-06-04>> Add section Administration
    This section describes the common elements of SACM that are involved in managing
    assurance cases, exchanging assurance cases and related concerns. The elements
    described in this chapter organize instances of SACM. In particular, this section defines
    the root object of an assurance case - the AssuranceCase element. This element contains
    other objects in the assurance case, such as the Argumentation objects and
    EvidenceContainer objects and constitutes a unit of exchange using the SACM as the
    protocol.
    In addition, the SACM Argumentation Metamodel and the SACM Evidence Metamodel
    constitute two independent protocols within SACM, so Argumentation packages can be
    developed and exchanged using the Argumentation elements, and also the
    EvidenceContainers can be developed, managed and exchanged independently of the
    Argumentation elements or in combination with them. Independently developed
    Argumentation packages and EvidenceContainer packages can be later assembled into
    complete assurance cases. Specifications of the Evidence Metamodel can be used to
    develop an evidence repository that can be used to store and manage evidence in support
    of multiple assurance cases.

    "id". The global referencing scheme may involve gid+id combination, while a local
    scheme may use id component.

    2. Conformance
    Structured Assurance Case Metamodel (SACM) specification defines the following 3 compliance points:
    Argumentation
    Evidence Container
    Assurance Case
    2.1. Argumentation compliance point
    Software that conforms to the SACM specification at the Argumentation compliance point shall be able to
    import and export XMI documents that conform with the SACM XML Schema produced by applying XMI
    rules to the normative MOF metamodel defined in the Argumentation subpackage of the SACM
    specification, including the common elements defined in the Common and Predefined diagrams of the
    SACM. The top object of the Argumentation package as a unit of interchange shall be the
    Argumentation::Argumentation element of the SACM.
    Conformance to the Argumentation compliance point does not entail support for the Evidence subpackage
    of SACM, or the Administration diagram of the SACM. Links to the evidence items in the Argumentation::InformationElement shall be made using the ‘url’ attribute. The ‘evidence’ association
    shall not be used.
    This compliance point facilitates interchange of the structured argumentation documents produced by
    existing tools supporting The Goal Structuring Notation (GSN) and Claims-Arguments-Evidence (CAE)
    notation. Examples of the SACM XML interchange documents and the corresponding GSN and CAE
    diagrams are provided in Annex B.
    2.2. Evidence Container compliance point
    Software that conforms to the specification at the Evidence Container compliance point shall be able to
    import and export XMI documents that conform with the SACM XML Schema produced by applying XMI
    rules to the normative MOF metamodel defined in this Evidence subpackage of the SACM specification,
    including the common elements defined in the Common and Predefined diagrams of the SACM. The top
    object of the Evidence package as a unit of interchange shall be the Evidence::EvidenceContainer element
    of the SACM.
    Conformance to the Evidence compliance point does not entail support for the Argumentation subpackage
    of SACM, or the Administration diagram of the SACM. Claims in the Evidence::ReferencedClaim element
    shall be explicitly defined using the ‘content’ attribute of the Evidence::ReferencedClaim element. The
    ‘claim’ association shall not be used.
    This compliance point facilitates interchange of the precise statements related to evidence. In particular,
    this compliance point facilitates development of evidence repositories in support of software assurance and
    regulatory compliance.
    2.3. Assurance Case compliance point
    Software that conforms to the specification at the Assurance Case compliance point shall be able to import
    and export XMI documents that conform with the SACM XML Schema produced by applying XMI rules
    to the normative MOF metamodel defined in this entire specification. The top object of the Assurance Case
    package as a unit of interchange shall be the SACM::AssuranceCase element.

Argument metamodel needs improvement

  • Key: SACM-167
  • Legacy Issue Number: 17347
  • Status: closed  
  • Source: Adelard LLP ( Luke Emmet)
  • Summary:

    The argument metamodel has some limitations that should be addressed to
    make it more coherent and simple. The following aspects need to be
    addressed:

    1. The annotation class is generally useful and should be promoted up
    the class diagram so it can be used more widely

    2. AssertedRelationships seem to be kinds of assertions (see related
    issue 16848) and so a number of related modelling updates will be needed
    to reorganise the model to reflect this, and to simplify by removing or
    renaming some of the abstract classes. An abstract Assertion class could
    be a useful common parent for both Claim and AssertedRelationship
    Classes. A simplification can be made then to rename the existing
    ArgumentLink as AssertedRelationship.

    3. We should have a simple referencing mechanism to allow referencing
    evidence in the evidence metamodel, or to reference other evidence by
    means of a URL directly (for when the user is only choosing to comply
    with the Argument compliance point)

    4. As the models are integrated it will be necessary to rename the top
    level element in ARM to be less generic

    I propose the following changes:

    Create a new Assertion class, as a subclass of ReasoningElement

    Set the Claim class to be a subclass of Assertion

    Rename the ArgumentLink abstract to be AssertedRelationship (removing
    the previous abstract class AssertedRelationship) and move the new
    AssertedRelationship class to be a child of the Assertion class

    Move the Annotation Class to a shared top level ModelElement, and
    include a content:String attribute

    Add an optional association from InformationElement to
    Evidence::EvidenceItem and add an attribute URL to InformationElement to
    be used to refer to evidence not held in the evidence model.

    Rename the ModelElement to be ArgumentationElement, and move the
    id:String attribute to its new parent ModelElement, which is part of the
    shared classes for the argumentation and evidence parts of SACM.

    Edit section 9.2.7 InformationElement Class as follows:
    Add an “attributes” section with the following content:
    url : string
    An attribute recording a URL to external evidence
    Add a new sentence at the end of the Semantics section as follows:
    “The url attribute is only to be used when only the argumentation aspects of SACM are
    complied with. If compliance is claimed against both the argumentation and evidence
    packages, then an association to Evidence::EvidenceItem shall be used to reference
    evidence by means of a URL”
    Add an "associations:" section with the following content:

    source:ArgumentElement[0..*] Reference to the ArgumentElement(s) that are the
    source (start-point) of the relationship.
    target:ArgumentElement[0..*] Reference to the ArgumentElement(s) that are the
    target (end-point) of the relationship.
    Semantics section, delete first sentence, replace with “In SACM, the structure of an
    argument is declared through the linking together of primitive ArgumentElements.”
    Edit section 9.2.13 AssertedInferenceClass as follows:
    Delete first para, replace with “The AssertedInference association class records the
    inference that a user declares to exist between one or more Assertion (premises) and another Assertion (conclusion). An assertion may be the target in more than one
    AssertedInference. It is important to note that such a declaration is itself an assertion on
    behalf of the user.”
    Semantics section, delete existing content, replace with “The core structure of an
    argument is declared through the inferences that are asserted to exist between Assertions
    (e.g. Claims). For example, an AssertedInference can be said to exist between two claims
    (“Claim A implies Claim B”). An AssertedInference between two claims (A – the source
    – and B – the target) denotes that the truth of Claim A is said to infer the truth of Claim
    B.”

Evidence Metamodel needs a Record element

  • Key: SACM-166
  • Legacy Issue Number: 17316
  • Status: closed  
  • Source: KDM Analytics ( Dr. Nikolai Mansourov)
  • Summary:

    Currently the Evidence metamodel has a general class Exhibit, and one concrete class Document. However the feedback from Regulatory Compliance community is that there should be an explicit element to represent electronic records of compliance.
    Suggested resolution is to add Record element as a concrete subclass of Exhibit. Resolutions in Ballot 5 are addressing the issue of moving the DocumentProperties up the inheritance chain so that these Properties are available for Records.
    This is a minor semantic enhancement that will allow better differentiation between various exhibits, and will allow management of electronic records for compliance.

  • Reported: SACM 1.0b1 — Thu, 19 Apr 2012 04:00 GMT
  • Disposition: Resolved — SACM 1.0b2
  • Disposition Summary:

    Add section Record to chapter 10 as follows:
    Record
    Record element represents Exhibits that are explicit records of compliance, for example
    log entries. Record is different from a Document, since a Document element represents
    some physical object that exists elsewhere in the physical world (even if it is an
    electronic document), while a Record element exists directly in the EvidenceContainer.
    Superclass
    EvidenceElement
    Attributes
    name:String the name of the record
    content:String the content of the record
    Semantics
    Record is defined as "a thing constituting a piece of evidence about the past, esp. an
    account of an act or occurrence kept in writing or some other permanent form". In the
    Evidence Metamodel Record element is such thing. In contrast to a Document element, a
    Record is not a representative of some other physical object, but the object itself. A
    Record is therefore similar to an Object, however it is considered a structured element
    with an informal content rather than a formal element.
    Changes to Figure EvidenceElements (Figure 10.1) were illustrated in related resolutions
    (e.g. 16800) and is presented below. <<diagram on p 121 of ptc/2012-06-04>>

    Add new section Common Elements Class Diagram to chapter 8 SACM Assurance Case
    Add Common Elements diagram as follows: <<diagram on p 106 of ptc/2012-06-04 >> Add SACMElement section
    SACMElement
    A SACM element is a top-level element for the Structure Assurance Case Metamodel.
    This is an abstract class that directly extends MOF::Element. Every class in SACM is a
    (direct or indirect) subclass of SACMElement.
    Superclass
    MOF::Element
    Semantics
    The SACMElement is a common class for all meta-model elements that represent some
    element of a structured assurance case.
    Remove ModelElement section 9.2.1, page 23
    Add ModelElement section to chapter 8 in the following way:
    ModelElement Class (Abstract)
    A ModelElement is an atomic constituent of a structured assurance case represented
    using the Structured Assurance Case Metamodel. In the meta-model, ModelElement is the top meta-element in the SACM Common class hierarchy. ModelElement is an
    abstract meta-model element.
    Attributes
    • id: String A unique identifier for the SACM entity.
    Associations
    taggedValue:TaggedValue[0..*] This association enables the association of one or more
    user defined TaggedValues to any ModelElement.
    annotation:Annotation[0..*] user defined annotations associated with the current element
    Semantics
    The ModelElement is a common class for all meta-model elements that represent some
    element of a structured assurance case.
    Invariants
    • context ModelElement inv UniqueIdentifier: ModelElement.allInstances()->
    select(me:ModelElement|me.identifier=self.identifier)->size()= 1
    Add UtilityElement section to chapter 8 in the following way:
    UtilityElement Class (Abstract)
    A UtilityElement is an atomic constituent of a structured assurance case represented
    using the Structured Assurance Case Metamodel. In contrast to a ModelElement,
    UtiiltyElement represents auxiliary constructs that extend ModelElement and that are
    only used as part of some ModelElement. In particular, such UtilityElement cannot be
    referenced outside of the owner ModelElement. UtilityElement is an abstract class.
    Semantics
    The UtilityElement is a common class for all meta-model elements that represent some
    auxiliary element of a structured assurance case.
    Move TaggedValue section 9.2.2, page 24 to chapter 8
    Change superclass of TaggedValue to UtilityElement
    Change sentence in the description of TaggedValue element as follows:
    A TaggedValue is a structured annotation that can be provided on any ModelElement in
    the Structured Assurance Case Metamodel.
    Change sentence in semantics section from:
    This is a deliberately general mechanism to allow users to associate tags that they find
    useful for any Argumentation Metamodel instance.
    into
    This is a deliberately general mechanism to allow users to associate tags that they find
    useful for any Structure Assurance Case Metamodel object.
    Add Annotation section to chapter 8.
    "
    Annotation
    An Annotation element represents informal and unstructured user-defined content to any
    ModelElement of the Structure Assurance Case Metamodel. In contrast, a TaggedValue
    element allows more structured content to be added to elements.
    Superclass UtilityElement
    Attributes
    content:String the text of the annotation
    Semantics
    It can be useful to be able to add informal text to the ModelElements. For example,
    Annotation elements can record comments, notes and general explanations. This is a
    deliberately general mechanism to allow users to associate annotations that they find
    useful for any Structure Assurance Case Metamodel object.
    "
    Modifications to the Argumentation Metamodel and the Evidence Metamodel parts are
    described in related resolutions. In particular, we are adding a reference from
    Argumentation::InformationElement to Evidence::EvidenceItem and from
    Evidence::ReferencedClaim to Argumentation::Claim

    Semantics
    EvidencePackage element is the root object of an instance of the Evidence Metamodel
    (which can be referred to as Evidence Model). A single EvidenceContainer is a unit of
    exchange of evidence information. All Element defined in an EvidenceContainer are
    exchanged together as part of the EvidenceContainer. Elements that are referenced shall
    be either present in the EvidenceContainer or in one of the EvidenceContaienrs that is
    specified as required for the EvidenceContainer. The Evidence Metamodel does not
    require completeness of the closure of all required packages.
    The properties of the EvidenceContainer element make assertions regarding the current
    container (use the current container as the subject of the corresponding clauses).
    Therefore, the following properties for an EvidenceContainer can be readily interpreted
    in the above way:
    RequiresContainer (for example, verbalized as "the EvidenceContainer requires container
    X1")
    ContainerConsistency (for example, verbalized as "the elements of the
    EvidenceContainer are interpreted formally")
    ContainerCompleteness (for example, verbalized as" the EvidenceContainer is in draft
    state")
    CompliesTo (for example, verbalized as "The EvidenceContainer complies to the
    Resolved Counter Evidence proof standard")
    All ProjectProperties clauses directly owned by an EvidenceContainer shall be
    interpreted with the EvidenceContainer as the main subject. For example, "The
    EvidenceContainer depends on evidentiary support rendered by exhibit E1 to the claim
    'testing is completed'"
    Replace Figure 15.1 with the following (see also resolution 16815): <<figure on p 99 of ptc/2012-06-04>> Add section ProjectProperties to chapter 15 (see also resolution 16818).

      EvidenceContainer. This is a commitment to the set of evidence containers that need to
      be processed together. Add section ContainerConsistency as follows:
      ContainerConsistency ContainerConsistency element is a counterpart of the Consistency property of Documents.
      ContainerConsistency clause makes an assertion about the subject EvidenceContainer
      regarding the level of formality of the element of the container. In combination with other
      container properties, such as ContainerCompleteness and CompliesTo, this clause
      determines capability to interpret the elements of this container. Consistency of an

      ContainerCompleteness element is a counterpart of the Completeness property of Documents.
      ContainerCompleteness clause makes an assertion about the subject EvidenceContainer
      regarding the level of completeness of the element of the container. In combination with
      other container properties, such as ContainerConsistency and CompliesTo, this clause
      determines capability to interpret the elements of this container. Completeness of an

      the key-value pair of the corresponding TaggedValue element.
      ExtendedProjectProperty characteristic can not be verbalized using the standard
      vocabulary of the Structured Assurance Case Metamodel. However, the key and value
      pair may be carefully named to result in meaningful verbalizations for the targeted
      community in the selected language.

    Semantics
    DomainClaim is an element of meaning that states a generic proposition about the
    assurance case domain. DomainClaim is an informal element that represents claim as
    prose in a natural language (formal or informal), without identifying its structure.
    DomainClaim element can represent informal claims (claims not linked to any formal
    definition of its meaning, such as an ontology developed by some community of
    meaning) or unstructured claims (where the subjects are not identified).
    Usually claims state existence of a formally defined relationship between several
    individual domain objects and involve several subjects bound to specific roles. Assertion
    element can be used to capture this structure of a claim in a more formal way. In
    particular, Assertion element can link the proposition to an external vocabulary or
    ontology that defines the exact meaning of the proposition, as well as the exact subjects

    An Assertion is a relationship involving one or more formal objects, taken as formal
    proposition that has a distinct, separate existence, a self-contained piece of information
    that can be referenced as a unit. Assertion is the key constituent of a conceptual model
    underlying the assurance case. Assertion represents an asserted fact about the subject area
    for which the assurance case is being developed.

    • definition:MOF::Element A link to an entry of an external SBVR vocabulary or
    an OWL ontology defining the fact type of the assertion.
    Semantics
    Assertion is an element of meaning that states existence of a relationship between several
    individual formal objects. In a formal assurance case, the nature of the relationship is
    specified through a reference to an external vocabulary, such as an SBVR vocabulary or
    an OWL ontology. SACM assumes that the community of interest for the assurance case
    will acquire or develop such vocabularies for the corresponding subject area. In a semiformal
    assurance case the nature of the relationship can be described informally through a
    'content' property. In this case the 'definition' property and the 'facttype' property shall not
    be used. However the references to the exact FormalObjects through RoleBinding
    elements can be still stated. The 'content' property of the FormalAssertion element
    provides the verbalization of the assertion, in the form of an expression of the assertion in a selected natural language. For informal assurance cases, a ReferencedClaim element
    can be used, which only contains the verbalization of the claim in a natural language.

    into
    For example, let's assume the following evidentiary relationships:
    Exhibit A supports claim "Bob is married to Alice"
    Exhibit A challenges claim "Bob is single"
    We can observe that the claim "Bob is married to Alice" conflicts with the claim "Bob is
    single"
    Let's further assume the following evidentiary relationship:
    Exhibit C supports claim Exhibit A is likely a forgery
    We can observe that
    The evidence assertion Exhibit C supports claim "Exhibit A is likely a forgery" weakens
    support given by the Exhibit A to the claim "Bob is married to Alice"
    at the same time we do not directly assert that

  • Summary:

    To stipulate the structure of the id of an element is over-constraining. If the URL of the organisation is important to capture, then there should be a separate attribute for it; the name of the SAEM class is surely redundant. It should be sufficient to state that, whatever the identifiers used, they are to be globally unique, and let the implementers solve the problem how they will.

  • Summary:

    Rather than trying to enumerate all the possible properties that evidence could possess, it may be better to consider a extensible mechanism such as the TaggedValue class in ARM. This principle would simplify the model considerably if applied to all such properties, by the time Provenance, TimingProperty, CustodyProperty, EvidenceProperty and DocumentProperty sub-classes have been taken into account. Detailed enumerations such as these are bound to be incomplete; user defined values are more flexible.

    statements related to evidence. One of the goals is to facilitate normalized representation
    of such statements as well as the mapping of such statements to RDF triples. Therefore, a
    uniform mechanism was selected, which involves using an explicit association class

    statement. The above suggestion does not satisfy these objectives.

    The class “IsPartOf” is an example of an instance in the standard where a class is used to represent a relationship where a simple UML association would do.

Increased clarity needed

  • Status: closed  
  • Source: MITRE ( Mr. Samuel Redwine)
  • Summary:

    While clarity needs improvement throughout, the following are specific instances:
    • An explanation is needed of how the two sets of provenance-related classes and event-related classes need to be clearly and cleanly related to each other and to other elements.
    • The terms “role” and “rolebinding” need clear explanations..
    • The word “role” appears to be used both casually and technically. Use it only in the latter way.
    • Term “subject claim” is unnecessary and potentially confusing ­ why bother users with it.
    • As introductory material, Figure 1 is unclear, for example “evidence observation” sounds like an observation done to obtain evidence.
    • Meaning of “revoked” is unclear as generally nothing should be destroyed. Something might be excluded from assurance case (and maybe later brought back).

  • Summary:

    The distinction between "property" and "attribute" is unclear and could be confusing; and it is unnecessary.

    An EvidenceProperty is defined to be "fundamental" and different kinds of properties are variously defined to be “a physical characteristic” “common”, “a single characteristic of the exhibit ,“ “provenance and timing characteristics “… Attributes are presumably otherwise ­ not fundamental. For example, “EvaluationAttribute is an abstract class that represents certain characteristics of various evidence elements that were asserted during the course of evaluation.”

    At one time, property was agreed to mean something inherent. “Fundamental” is even less clear than “inherent”.

    For example, physical measurements are always (or almost always) not inherent and can vary because of conditions and measurement error. Weight is not inherent, and how meaningful would it be to say it is fundamental? Provenance and [e.g. creation. revision] timing characteristics are often questionable and are they “fundamental”. The body of the evidence does not generally change if they are changed.

    The motivation for naming some things as a property and others as an attribute might on the surface appear to have some merit. In the end, however, this distinction turns out to be simply difficult and confusing. Any usefulness is questionable, and it is entirely unnecessary. It should be dropped and all such things called an “attribute”.

  • Disposition Summary:

    There is agreement to the suggested approach. Furthermore, this has been already
    resolved to the extent possible through related issues 16730, 16731, 16740, 16705, where
    most statement related to evidence are constructed using the elements that are subclasses
    of EvidenceProperty, with the only exception of EvidenceAttribute. This element is
    different, since it provides some measurable values related to the quality of the
    evidentiary support rendered by a certain Exhibit. There is also a common superclass
    called EvidenceAssertion. Editorial changes will further downplay the distinction
    between the 'fundamental' and 'contestable' assertions related to evidence and evidentiary
    support.

    EffectiveTime element represents a property of the owner EvidenceElement object or
    EvidenceAttribute object. This element is an abstract class that establishes a relationship
    between the owner object and the detailed of the effective time interval of the owner
    object, defined by a particular concrete subclass of the TimingProperty element.
    into
    Semantics
    EffectiveTime element represents a statement about the subject EvidenceElement (an
    object that owns the instance of one of the concrete subclasses of this element). The
    EffectiveTime element specifies a time interval associated with the subject, during which
    the subject is asserted to be "effective". For example, in case of an EvidenceAssertion or
    a FormalAssertion, this element specifies a time interval at which the corresponding
    statement is asserted to be true. In case on am EvidenceItem this element specifies the
    relevant time context in which the element shall be considered.

Modify term “evidence collection project”

  • Key: SACM-4
  • Legacy Issue Number: 16290
  • Status: closed  
  • Source: MITRE ( Mr. Samuel Redwine)
  • Summary:

    Use of term “evidence collection project” is misleading as evidence is collected, generated, acquired, derived, evaluated, and it and information about it exchanged ­ and maybe other kinds of actions. A question also exists about whether it should be called a “project” as it is generally a crosscutting concern/effort within projects. Suggest, in order of preference, “included in interchange”, “involved in interchange” or “evidence-related efforts”. Emphasis on interchange is better where possible, but a mix of these might be needed.

A more generally available "citation" capability

  • Key: SACM-3
  • Legacy Issue Number: 16288
  • Status: closed  
  • Source: MITRE ( Mr. Samuel Redwine)
  • Summary:

    A generally available "citation" capability is needed. This should be able to refer to points throughout the assurance case and outside. This is particularly required inside ArgumentDescriptions, Context, and narrative elements but potentially useful essentially everywhere throughout SACM. In addition to all the merits of referencing, it is potentially a means to avoid duplication.

    How to do this from within an ArgumentDescription such as to localize within the referring element may require a different kind of mechanism than one that is associated with the element as a whole. Although not necessarily as critical, being able to cite a portion of an element is also important.

    "supervisor" of an evidence assertion, the "owner" of an evidence item, the 'executor' of
    an evidence event and the "custodian" of an evidence item. This vocabulary facilitates
    exchange of structured statements related to evidence. Additional roles related to the
    affiliation of a Stakeholder in some Organization can be defined by the corresponding
    community of interest. These roles can be used in HasRoleIn statements and exchanged
    informally, as the value of the "role" attribute". On the other hand, formal statements

    Page 12, Figure 2, Page 15, section 8.2.6 and page 16, section 8.2.9: In Figure 2, the attributes “toBeSupported” and “assumed” appear in the same class (Claim), but in the subsequent sections “toBeSupported” appears in ReasoningElement (a super-class of Claim). It seems that these two attributes are related: nothing should be both “assumed” and “to be supported”. This suggests that either:

    a. The “toBeSupported” attribute should be removed on the grounds that any Claim that is not assumed should have support, and if it doesn’t, then it is yet to be supported; or

    b. A single attribute should be used to represent three states: assumed, supported or not-
    yet-supported (alternatively: assumed, needs-no-support and needs-support); or

    c. An invariant should be present to state the constraining relationship between the two attributes described above.
    Note that “toBeSupported” could be construed as a process issue, and therefore better treated as a TaggedValue to make the model less prescriptive.

    Note also that the “toBeSupported” attribute should be constrained to be false in the EvidenceAssertion class, as well as, possibly, the “assumed” attribute

  • Summary:

    There is an inconsistency between these two examples in the way that AssertedRelationships are represented. In the Bluetooth example, the AssertedInference “AI1” is permitted multiple targets, documenting the fact that a single inference connects multiple entities. In the Industrial Press example, however, a similar single interference is represented by multiple AssertedInference elements each with a single target. It is possible that both ways are necessary, because one may wish to associate different ArgumentReasoning elements to different parts of the AssertedRelationship; if this is the case, then is should be made clear.

    There is no longer an element InformationAssertion. There is an InformationElement, which may contain a
    reference to an EvidenceItem, and an abstract element called Assertion, which has a concrete subclass
    called Claim, and another set of subclasses related to an AssertedRelationship.
    It should be discouraged to use the TaggedValue mechanism to add assertion to an InformationElement,
    since this violates the nature of the SACM as a structured approach to exchanging assurance cases -
    subclasses of Assertion element should be used instead.

    The two fundamental classes of the fact model are Object and Assertion. An Object is an
    object of significance, about which information needs to be known or held. Usually an
    Object corresponds to an Exhibit. Exhibit element emphasized the physical object (an
    SBVR thing element) while an Object emphasized the associated element of meaning. An
    Assertion is a relationship taken as an element of claim that has a distinct, separate
    existence, a self-contained piece of information that can be referenced as a unit. In the
    scope of SBVR, such units of information are called facts, hence the name fact model.
    into
    The two fundamental classes of the Formal Statements are FormalObject and
    FormalAssertion. A FormalObject is an object of significance, about which information
    needs to be known or held. Usually a FormalObject corresponds to an Exhibit where the
    Exhibit element emphasizes the physical object (an instance of the SBVR 'Thing'
    concept) while a FormalObject emphasizes the associated element of meaning. (an
    instance of the SBVR 'Meaning' concept). A FormalAssertion is a relationship between
    evidence elements taken as a new assertion/claim that has a distinct, separate existence; a
    self-contained piece of information that can be referenced as a unit. In the scope of
    SBVR, such units of information are called facts.
    change last part of the paragraph section 12, on page 49 from:
    So, an Assertion element represents a fact involving one or more Objects. A RoleBinding
    element represents an association, linkage, or connection between Objects within the fact
    that describes their role within the fact. RoleBinding represents some semantic
    association between entities of evidence information.
    Fact model elements correspond to some external ontology or vocabulary. Therefore in
    the SACM Evidence Metamodel, the superclasses of Object and Assertion are called
    DomainObject and DomainAssertion respectedly as these elements are part of the
    conceptual model of the Domain for which the assurance case is being developed.
    The SACM Facts package is aligned with the OMG SBVR specification, in particular
    Object can be linked to SBVR IndividualConcept and Assertion can be linked to SBVR
    fact.
    This alignment is important since the Evidence Metamodel can be viewed as a standard
    vocabulary related to descriptions of evidence. SBVR rules can be written using this
    vocabulary to formally describe further properties of evidence information. Such
    vocabulary is presented in Appendix 1.
    The SACM Evidence Metamodel is also aligned with the RDF. Object and Assertion can
    be represented as RDF resources, and RoleBinding - as RDF triples.
    into So, a FormalAssertion element represents an assertion involving one or more
    FormalObjects. A RoleBinding element represents an association, linkage, or connection
    between the FormalObjects that describes their role within the assertion.
    Formal Statements are based on some pre-defined conceptual model related to the area
    for which the assurance case is developed. Such conceptual model can be formally
    represented as an external ontology or vocabulary. In particular the SACM Evidence
    Metamodel allows linking an Object element to an SBVR IndividualConcept or SBVR
    noun concept element and the Assertion element to SBVR fact type element
    The Object element is aligned with the SBVR IndividualConcept or the SBVR noun
    concept while the Assertion element is aligned with the SBVR fact. type. Further, the
    entire SACM Evidence Metamodel is aligned with the OMG SBVR specification, in such
    a way that it describes a standard vocabulary related to descriptions of evidence. SBVR
    rules can be written using this vocabulary to formally describe further properties of
    evidence. The full SBVR vocabulary for evidence is presented as a non-normative Annex
    A.

    Change text on page 13 into:
    The key concept of evidence is a Document that provides evidentiary support to some Subject claim.
    Document is collected during the course of Evidence collection process. Usually a Document is interpreted
    as a description of a certain state of affairs involving several objects in the subject area (for which certain
    claims are being made). Subject claims are assertions related to the state of affairs in the subject area.
    Evidence evaluation (as opposed to Evidence collection) involves certain specific Claims about Evidence,
    in particular, Evidence Relation describes the nature of the evidentiary support between a Document and a
    Subject Claim, or the interpretation of a Document as a meaning. Evidence Relation involves certain
    attributes that qualify relations between Documents and Subject Claims, or Documents and meanings.
    Evidence Observations describe conflicts between evidence relations. Evidence Resolutions record
    judgments that resolve conflicts in evidence relations. Note, that Documents and Subject Claims simply
    exist. A Document becomes Evidence only insofar as it is claimed to provide evidentiary support to a
    certain Subject Claim.

    Creation, Acquisition or Derivation of an EvidenceItem, Transfer of an EvidenceItem,
    Evaluation of an EvidenceItem and Revocation of EvidenceItem. An EvidenceEvent
    statement describes a certain characteristic of the subject EvidenceItem. More complex
    Event statements can be constructed using the EvidenceEvent element by adding some
    properties that describe the detail of the event, such as the Provenance, Timing, and
    Custody. The entire chain of custody of an evidence item can be established by analyzing
    the EvidenceEvents of the item. Concrete evidence events are defined as subclasses of the
