I just put online a small Prolog script, allowing to generate XHTML specification out of a RDF vocabulary (it should work for both RDFS and OWL). It is really similar to the Python script the SIOC community uses (thanks Uldis for the code:-) ), regarding the external behavior of the script. It provides a few enhancement though, like support of the status of terms, OWL constructs, and a few other things. You can check the Music Ontology specification to see one example output, generated from a RDFS/OWL file.

Here is the script.
