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.
