Does Eclipse UML support diagram interchange? It seems that DI is a part of UML 2.5 specification. But I can't find UMLDiagram class and others in Eclipse UML.
Do you plan to implement them?
I guess that Papyrus implement UML 2.5 DI. Is it possible to use DI metamodel in our project. We don't need Papyrus editing finctionality. We need only to parse/serialize UML 2.5 DI. Is it possible somehow?
UML DI is partially supported by Papyrus, as an extra-component. Papyrus also provides a feature to export Papyrus diagrams to UML DI
Eclipse/UML itself doesn't provide such support, but you can probably reuse the UMLDI Metamodel from Papyrus (Although we don't consider it stable yet, I believe it's good enough and shouldn't change "too much", if at all)
