4. 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. “

11. 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
