Review of Two UML Open Source Tools

This is a quick review of two interesting, open source UML tools: Topcased UML and Papyrus UML. They are both based on Eclipse.
  • Both products use Eclipse UML2, an EMF-based schema, so it is possible to exchange data between them (and other products using the same UML model file format).
  • Papyrus documentation is nearly non existant - IDE help is either empty or refers to external avi (sic!) files, Topcased is much better.
  • There is a convient Papurys bundle install, Topcased users need to use Eclipse update.
  • Topcased allows to export single or group of diagrams to several image formats, Papyrus does not.
  • Both products supports meta-models and UML2 profiles.
  • They are both available under Eclipse Public License (EPL).
