Just a quick thought:

I’m convinced that each company needs its own, internal version of Google’s Knowledge Graph – all the information that’s vital to the business, in “complex models with many connected entities” (Axel Morgner), to help improve search, bridge data silos, and make metadata entry much easier.

Listen to Dr. Andreas Weber make his case: Semantic PDM: Using a Graph Data Model at Schleich. (I heard him talk about it at the Neo4j Graph Talks in Hamburg, see the German slides on Semantic Data Management).

More on this (Semantic relationships, deep content, Topic Maps, Storylines) in my post: It’s content, not just DAM metadata
