At risk of sounding like a broken record (there's an anachronism for you),
I understand what we can gain by using semantic tools. I still have not clearly understood what we gain by RDF. What is wrong with simply tagging the schema elements with id attributes (or even rdf attributes - schema-schema is defined to support attributes from any other namespace) and then have an external ontology based on this?

... this is essentially the approach taken by GML, and if I understand correctly, by ISO 19109. However, I do not know of tools that validate the internal semantic consistency of GML expressions or ISO 19109-compliant models.
