PIMped Papyrus - A Language Workbench for UML DSLs


The NIEM Modeling Tool project is an open source toolset built on the Eclipse 4 platform for creating standards-based information exchanges between local and national law enforcement agencies.

With the beta launch of the product this month, we take a step back to reflect on what it takes to write a graphical language workbench for a UML PIM DSL. Using Martin Fowler's criteria for defining a new DSL as the framework for this session, we will explore some of the NIEM toolset's features, and how you can use these same ideas to develop a graphical IDE for other DSLs:

  • UML Stereotypes for the language syntax
  • Papyrus extensions, palette, and properties customizations for the graphical editor
  • QVT to generate artifacts from the abstract representation
  • Lucene for indexing existing libraries for importing them into your model
  • Epsilon for runtime validation
