SYSML11 — 8.3.1.3 UML Diagram Elements not Included in SysML Block Definition Diagram

  • Key: SYSML11-59
  • Legacy Issue Number: 11591
  • Status: closed

  • Summary:

    "An “X” on a single end of an association to indicate that an end is “not navigable” has similarly been dropped, as has the use of a small filled dot at the end of an association to indicate an owned end of an association."

    In this text I see two mistakes:

    1. "filled dot" notation is used for ends owned by associated classifier, not owned by association (an opposite situation).

    2. "owned end of an association" does not mean it is not navigable. Association has "navigableOwnedEnds" property for navigable owned ends.

  • Disposition: Resolved — SysML 1.1
  • Disposition Summary:

    Correct the descriptions of the UML notations which SysML excludes.
    The statement about an "X" on the end of an association does seem consistent with this statement from the UML Superstructure spec, under 7.3.3 Association, "Notation" subsection:
    A small x on the end of an association indicates the end is not navigable.
