Issue 3368: Efficient diagrammatic notation for Collaboration Specifications (uml2-superstructure-ftf)
Source:  (, )
Nature: Enhancement
Severity: Significant
Summary: I have played a lot with different ways of showing how several collaboration specifications may appear in one class diagram.

Right now, there are collaboration specification diagrams, and there are class diagrams that feature template instantiations, but no class diagrams that feature collaboration specifications. If you use a round ellipse for hooking up a collaboration specification into a class diagram, you will see ellipses all over the place, but will not see how the collaboration specifications relate to the associations between the classes.

I can show you the variations of how to draw collaboration specifications in class diagrams. In case you wonder whether you really need this, I can offer you my whole Ph.D. thesis, which is on framework design using role modeling :-)) There is plenty of other work going into this direction, for example Erich Gamma’s pattern annotations in class diagrams.

Discussion: 
UML 2.0 resolves this problem with the introduction of CollaborationOccurrence (sorry
for the strange name). A collaboration occurrence represents one particular use of a
collaboration to explain the relationships between the properties of a classifier.
Associated dependencies map features of the collaboration type to features of the
classifier. These dependencies indicate which role in the classifier plays which role in the
collaboration.
