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 project 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 to represent a language syntax
* Papyrus extensions, palette and properties view customizations for the graphical editor
* QVT to generate artifacts from the abstract representation
* Lucene for indexing existing libraries for import them into your model
* Epsilon for runtime validation
