Issue 6426: ad-03-04-01 Chap 2 p. 118 Figure 2-15/Components: Wiring notation (uml2-superstructure-ftf) Source: David Frankel Consulting (Mr. David Frankel, david(at)dfrankelconsulting.com) Nature: Uncategorized Issue Severity: Summary: Issue: Re Chapter 2, Components, Figure 2-15, p. 118: The figure caption says that the figure is an example of connector wiring, but the text directly below the caption says that the figure "may be used as a notation option for dependency based wiring." These two statements appear to be contradictory. Recommendation: To avoid having an ambiguous notation, specify that dependency notation should be used for dependency based wiring. (This recommendation may be affected by the resolution of the issue submitted about semantic distinctions between different ways to wire components together). Resolution: Revised Text: Actions taken: November 4, 2003: received issue March 9, 2005: closed issue Discussion: The statement may need to be revised but is consistent with the Interfaces chapter. A number of people have commented that the ball-and-socket notation is useful for structural diagrams (e.g. Martin Fowler). Note that we have other occurrences in UML where a notation has different meanings depending on context. E.g. a ‘straight line’ on a structural diagram means an Association whereas on a composite structure diagram, it means a connector.
