One of the common questions I hear in the semantic technology communities is why continue to create new ontologies (within the enterprise) and not re-use public domain ontologies and upper ontologies to model most domains. I will attempt to answer this, again from a practical and enterprise technical architecture viewpoint.

Describing some of the engineering behind the Press Association semantic publishing stack and how the ontology design and the software design work together in unison.

This is a brief guide to pragmatic ontology design. It is borne out of practical experience of designing ontologies for real world semantic publishing applications. It borrows design principles from good traditional software architecture techniques applying them to ontology design. It discusses the concepts that I will call the 3 C’s of ontology engineering..
