Title: RE: Ontology editor + why RDF?

A straight-foward "porting" is always wrong, or lack of the comprehension of difference between RDF and other exiting technologies.  RDB and XML schema contains implicit semantics that should be explicitly expressed in RDF.     [VK] Making the underlying data model constraints in the RDF graphs is what I meant by extra semantcis – In the relational model, that would correspond to primary, foreign keys, functional and inclusion dependencies, etc…. Some of this would likely require OWL…   Even so, why does it have to have new semantics?  The first thing first is to ground "things" on to the web.  Connecting a URI with another is as easy as it gets, the same can not be said about connecting a particular row of one DB to another.  The added value is not "all" about semantics, it is interoperability.   [VK] Exactly my point! The added value is all about cross-linking, which comes from the web infrastructure (URIs) and not from semantics!
