  1. OMG Issue

UML14 — issues and bugs on the UML 1.4 Draft

  • Key: UML14-7
  • Legacy Issue Number: 4300
  • Status: closed  
  • Source: Anonymous
  • Summary:

    This text contains an number of (mostly minor) issues and bugs on the UML 1.4 Draft of February 2001 (formal OMG document number : ad/2001-02-13). The issues are listed along with their pagenumbers in the order, in which they appear in the UML document.

    Note: Since the number of issues is quite large, it was decided tot put them in one piece of text. Submitting each item as a seperate issue, utilizing the predefined form at the OMG site would have incurred too much overhead.

    ---Begin of issues---------------------------- (p. xi) Typographical/Editorial: The page-footer still refers to OMG-UML V1.3.

    (p. xxi) Typographical/Editorial: The reference to the UML Extensions chapter is not valid anymore.

    (p. 2-34, Component) It is stated that "In the metamodel <text removed>. A Component is specified by the interfaces is <sic!> exposes". However, there is no meta-association linking Component (or Classifier ?) to Interface, nor is there an OCL contraint indicating this relation. This should be added.

    (p. 2-46, Interface) Same as the previous comment. Here the relationship between Interface and Classifier could/should be made explicit in the Abstract Syntax.

    (p. 2-47, ModelElement) It is stated that "It is the base for all modeling metaclasses in the UML". However, this is not true for the following constructs:

    ElementOwnership ElementResidence ElementImport TemplateParameter TemplateArgument Argument

    Please clarify or correct the statement.

    (p. 2-95, 2-98, Integer, String, UnlimitedInteger) It is stated that each of these is "a classifier element that is an instance of Primitive". This is cofusing, since the text on p. 2-92 makes it clear that this Primitive cannot be the subclass of DataType: this is used for datatypes defined by users of the UML. So which Primitive is this ? Is it a MOF (meta-meta-)class ? Please clarify.

    (p. 2-98, Uninterpreted) It is not clear why this construct is mentioned at all, since it is not shown in the Abstract Syntax, nor referenced anywhere else.

    (p. 2-106) Typographical/Editorial: The sequence of DestroyAction and DataValue is not according to alphabetic ordering

    (p. 2-111, Stimulus) A reference is made to MessageInstance. This is not an UML metaclass. Please correct.

    (p. 2-139, Overview and 2-142, UseCase) In both pieces of text references are made to instances of usecases and instances of actors (or a user playing the role of the Actor). This is confusing in the sence that the concept of a usecase instance is reified as UseCaseInstance, whereas the actor instance is not reified. Please clarify.

    (p. 2-182,2-183) Typographical/Editorial: The sequence of ActivityGraph and ActionState is not according to alphabetic ordering

    (p. 3-3) Typographical/Editorial: There is no Part 8.

    (p. 3-15, Type-Instance Correspondence) It is stated that "Examples of such pairs in UML include: <text omitted>, Parameter-Value, Operation-Invocation, and so on." This is confusing since the constructs Value and Invocation are not UML metaclasses. Please correct.

    (p. 3-22, Subsystem - Presentation Options) It is stated "As with packages, the contents of a subsystem may be shown using tree notation". Note however that this statement is not included with the passages describing the Package Presentation Options on p. 3-18. Please clarify or add.

    (p. 3-59, Stereotype Declaration - Semantics) It is stated "although it conceptually belongs in the layer below,the metamodel layer." The use of "below" is not in line with the usual representation of the meta-modeling architecture, such as in table 2-1 on p. 2-5. There the metamodel layer is "above". Please correct.

    (p. 3-60, Stereotype Declaration - Notation) The special stereotype of Dependency called <<stereotype>> is not mentioned in the semantics section of Dependency (on p. 2-36/2-37), nor in Appendix A, UML Standard Elements. Please add.

    (p. 5-21?, Chapter 5) Typographical/Editorial: The pagenumbering in the footer starts at page 5-21. Please correct.

    (p. 5-24, Figure 5-1) It is inferred from the packages shown that the Extension Mechanisms package is absorbed into the Core Package. This is not reflected elsewhere in the document. Please make the neccesary updates. If it is decided to do this only in the Interchange Model, and not in the Abstract Syntax, then this should be noted on p. 5-23 under the heading of "changes". In this case the title of Figure 5-7 on p. 5-30 should be changed to "Core - Extension Mechanisms".

    (p. 5-31, Figure 5-8) In comparison with the Abstract Syntax diagram on p. 2-91 the element Mapping has been omitted/deleted. Please clarify.

    (p. 5-32, Figure 5-9) In order to be consistent with the titling used in the other figures in this chapter, please change the title to "Datatypes - Expressions".

    (p. 5-36, Figure 5-14 and p.5-38, Figure 5-16) In comparison with the Figures 2-18 (p. 2-123) and 2-20 (p. 2-125) the follwing assoctiations have been omitted/deleted:

    Collaboration - AssocationRole Collaboration - ClassifierRole AssocationRole - AssocationEndRole

    Please clarify
