I was working in RDF/ontology space. IMO the additional domain knowledge required to model data correctly and publish them in a way an average user can comprehend and navigate properly is disproportional to the benefit of such data model. By the time everything is properly modelled the knowledge itself might be a bit obsolete (speaking from bio-tech related fields).
