Managing and Visualising OWL vocabularies

[bugbear]

We are working with OWL vocabularies, and would like to model the class hierarchy and properties in Enterprise Architect...

Has anyone tried this, or is there a method for importing and visualising an OWL vocabulary (typically these are located at a URL as RDF)

ie

http://purl.org/dc/terms/ (*view the source of the returned document)
or
http://rs.tdwg.org/ontology/voc/TaxonConcept (*view the source of the returned document)

OWL is typically represented as XML (RDF/XML - aka an RDF representation of an OWL vocubulary which has been serialised as XML)

In the simplest sense we need to represent Classes, Properities, 'Instances of Classes' and 'Values of Properties' which we need to import from an RDF/XML definition.

Does anyone have any suggestions on how I might be able to import into a model this kind of data (the source XML from URLs above) into EA?



Thanks in advance
