Connotea + Semantic Web = E.D.

What do you get when you combine social tagging with terms from web-accessible ontologies?

E.D. the Entity Describer

ED helps people use terms from ontologies* as their connotea tags.
Is it useful, interesting, a total waste of time? I'm not really sure yet, but it seemed like it would be fun. If you have some time, please do give it a try and let me know what you think! Details about installation etc. here

* Here 'ontology' just refers to any OWL/RDF document. The 'terms' are the rdfs:labels for the classes or the actual class name if the labels are missing. E.D. only "understands" rdfs:label and rdfs:subClassOf. It would make more sense to follow a SKOS model as the only semantics we plan to use are "broader-than" and "narrower-than"; but, since the large majority of OWL ontologies that we are interested in use subClassOf even when they mean skos:narrowerThan , we do the same within E.D. Support for ontologies/thesauri that are encoded with the SKOS ontology will be added as the need arises.
