Issue 6423: Section 9.3.4 page 161, Presentation Option (uml2-rtf) Source: Sparx Systems Pty Ltd (Mr. James D. Baker, omg(at)objectsandaspects.com) Nature: Uncategorized Issue Severity: Summary: The statement "A dashed arrow with a stick arrowhead may be used to show that a collaboration is used in a classifier, optionally labelled with the keyword «represents»." and the accompanying example are confusing. Please clarify what this presentation option is trying to accomplish. Resolution: see above Revised Text: In Section 9.3.4., delete subsection “Presentation Option”. Actions taken: November 4, 2003: received issue August 23, 2006: closed issue Discussion: I do agree with the submitter that this presentation option could be confusing. It has been taken over from UML 1.4 for reasons of backwards compatibility. While I have not seen any examples of actual use, it would be unwise to change this further in a backwards incompatible way without being able to point to practical experience of the use of this construct. If no practical experience can be found, it might be best to delete this presentation option.

Disposition: Defer Issue 6423: Section 9.3.4 page 161, Presentation Option Issue summary The statement 'A dashed arrow with a stick arrowhead may be used to show that a collaboration is used in a classifier, optionally labelled with the keyword «represents».' and the accompanying example are confusing. Please clarify what this presentation option is trying to accomplish. Discussion A search for practical applications of this presentation option has not revealed any examples. It is, therefore, proposed to delete this presentation option. -- ThomasWeigert - 18 May 2005 The issue is asking for a clarification and is not asking to remove the feature. If this is removed, there should be another way of depicting the Classifier::representation relationship (see figure 100). So, the resolution should provide an alternative to replace this notation and not just remove it. Alternatively, there should be an extended explanation of what this meta-association means. -- BranSelic - 19 May 2005 It is just that I have never seen any application of this. I did not feel I should remove this feature when we did UML 2.0 as at this time we did not have any evidence one way or the other. However, now I have searched for applications and am still coming up short. So in the spirit of making the language more manageable, removal of unused features that are in addition source of problems may be the best route? -- ThomasWeigert - 20 May 2005 If we can remove features we can add them. Which is fine with me in minor cases. -- ConradBock - 25 May 2005 I agree with Bran that this issue asks for clarification. Iit may be that no one is using it because no one understands it. -- ConradBock - 21 Jul 2005 I am not the right person to clarify this feature as I am not sure about it. I tried to reverse engineer the current description based on the UML1.x spec. Any takers? -- ThomasWeigert - 28 Jul 2005 Revised Test In Section 9.3.4., delete subsection .Presentation Option..
