Linked Data
„Linked Data is about using the Web to connect related data that wasn't previously linked, or using the Web to lower the barriers to linking data currently linked using other methods. “

Key Message
With OWLizer, you can transform any Ecore-based software language into OWL
With OWL constructs like sameAs and EquivalentWith, you connected similar concepts and instances over different languages
With SPARQLAS queries, you query multiple software artifacts
