Communication vs. Collaboration

[priyakubher]

Hi

Is it true that collaboration diagrams have been renamed communication is UML 2.0 spec? If so where can I find information about why and what changes have been specified.

Thanks

I just checked the UML 2.0 spec and it does mention the Collaboration as a collection of roles. And does not mention anything about a merge with Communication and yet many sites report that Collaboration and communication are the same.  Any idea why?

Thanks

From what I've read, it seems that UML 2.0 communication diagrams = UML 1.x collaboration diagrams, while UML 2.0 collaboration diagrams = UML 1.x collaboration diagrams without messages, plunked inside a collaboration oval. UML 2.0 collaboration diagrams show the roles played by objects in a collaboration with their types & connections, then links them explicitly to a collaboration. Take away the collaboration oval, add messages and sequence numbers and, voila! UML 2.0 communication diagram.

Cheers,
