Issues Descriptions

Should <> have a capital V?

  • Status: open  
  • Source: Boeing ( Alan Lee)
  • Summary:

    I'm not sure if this is actually an issue (I think it is). There are 2 keywords in Figure E.10: Spring Length Example; <<valueType>> and <<ValueType>>. Wondering if it is the same keyword and the latter should be lowercase v.

Refine / Trace relationship operations are too restrictive

  • Status: open  
  • Source: oose Innovative Informatik eG ( Tim Weilkiens)
  • Summary:

    Refine::getRefines(in ref : NamedElement) : AbstractRequirement should return NamedElement according to the definition of the refine stereotype in section 16.1. The body condition of the operation is not consistent with the return type AbstractRequirement.

    There is no constraint that restricts that one end of the refine relationship must be an element of type AbstractRequirement.

    Trace::getTracedFrom(in ref: NamedElement) : AbstractRequirement should return NamedElement according to the definition of the trace stereotype. The body condition should be updated as well from AbstractRequirement to NamedElement.

    The sentence in section 16.1 "A generic trace requirement relationship provides a general-purpose relationship between a requirement and any
    other model element." is too restrictive with regard to the definition of the trace stereotype.

VerdictKind should also have the literal none

  • Status: open  
  • Source: oose Innovative Informatik eG ( Tim Weilkiens)
  • Summary:

    As defined in the UTP element Verdict, the SysML VerdictKind should also define an enumeration literal none:

    none The test case has not been executed yet.

    When a test case is not executed yet or just invoked, its verdict is none. None indicates that no communication between
    test components and the SUT has been carried out yet. None is the weakest verdict. It is never set by the tester directly.

AllocateActivityPartition: Reference to UML specification is wrong

  • Status: open  
  • Source: oose Innovative Informatik eG ( Tim Weilkiens)
  • Summary:

    The second constraint of the stereotype AllocateActivityPartition references a section in the UML specification:

    "To depict this kind of direct responsibility, the modeler is directed to the UML 2 standard, sub clause 12.3.10, "ActivityPartition," Semantics topic."

    Subclause 12.3.10 does not exist. It is probably 15.6.3.1 in UML 2.5.1.

    I propose to remove the subclause reference number.

QUDV library inconsistently uses SysML::Libraries::PrimitiveValueTypes

  • Status: open  
  • Source: oose Innovative Informatik eG ( Tim Weilkiens)
  • Summary:

    I also realized that the QUDV library inconsistently uses in a few places SysML::Libraries::PrimitiveValueTypes when in fact it should use UML's PrimitiveTypes.

    I believe that this is a new issue for SysML 1.3.

Comments in the XMI have no annotated elements

  • Status: open  
  • Source: oose Innovative Informatik eG ( Tim Weilkiens)
  • Summary:

    The comments in the XMI that specify the documentation of the stereotypes and stereotype attributes do not annotate the elements they document.

Table 8.3: Row ActorPart shows Actor

  • Status: open  
  • Source: oose Innovative Informatik eG ( Tim Weilkiens)
  • Summary:

    The row ActorPart in table 8.3 should depict SysML::Blocks::PartProperty typed by UML4SysML::Actor, but it shows an Actor.
