  1. OMG Issue

ALF11 — Alf should be based on fUML 1.1

  • Key: ALF11-27
  • Legacy Issue Number: 18393
  • Status: closed  
  • Source: Model Driven Solutions ( Mr. Ed Seidewitz)
  • Summary:

    Specification: Action Language for Foundational UML (Alf): Concrete Syntax for a UML Action Language, FTF-Beta 2 (ptc/2012-08-43)

    The Alf syntax and the description of its semantics are based in UML 2.4.1. However, the formal semantic mapping is to fUML 1.0, which is based on UML 2.3. This means that the normative XMI for the Alf Standard Model Library is also UML 2.3, since it uses the fUML 1.0 Foundational Model Library. This situation occurred because the fUML 1.1 revision, based on UML 2.4.1, was not completed in time before the Alf 1.0 FTF had to deliver its report. Now that fUML 1.1 has been adopted, the Alf specification should be updated to use it as the target of the normative semantic mapping, which would also allow the Alf Standard Model Library to be UML 2.4.1.

    (Note that this issue is not intended to request that Alf incorporate the new Real type, which would require syntactic changes to the language and extension of the Standard Model Library. It is simply intended to request that the technical specification and normative artifacts for Alf all be consistently based on UML 2.4.1.)

  • Disposition: Resolved — ALF 1.1
  • Disposition Summary:

    Alf should be based on fUML 1.1

    Actually, the finalized Alf 1.0 spec still references UML 2.4 in Clause 3 Normative References. This should be updated to UML 2.4.1, along with updating the fUML reference to fUML 1.1. Once this is done, no change is necessary to the mapping specification, since that only generically refers to fUML and UML, not to specific versions.
    For the Standard Model Library, Subclause 11.2 Primitive Types needs to be updated to replace the use of the UML::AuxiliaryConstructs::PrimitiveTypes package from UML 2.3 with the separate PrimitiveTypes package from the UML 2.4.1 infrastructure. Then the normative XMI for the library needs to be regenerated as a UML 2.4.1/XMI 2.4.1 file.
