Data Modeling and RDF: Redux

Following up on my last post, I thought I’d drop this link – Data Modeling, RDF, and OWL.  This is a good article written for TDAN by David Hay about the field of semantics from the perspective of data modeling.

He makes the good point that a relational data model is a sort of ontology.  It does outline the high-level concepts (entities) and the relationships between those entities.  Most semantic types would probably say that a database schema is myopic in that it’s too focused on whether last names are 22 characters or 30, and not focused enough on the relationships that pull concepts together.
