RDFCore suggests that the text be modified to be less specific. There are also potential difficulties with the reference to RFC 2396; it would be better to refer to the RDF specs and let them take the heat on any 'interpretation' of RFC 2396. > > We suggest: > > [[ > A document describing an ontology typically contains information about the ontology itself. An ontology is a resource, so may be described using properties from the OWL and other namespaces, e.g. > > <owl:Ontology rdf:about=""> > <owl:versionInfo> ... </owl:versionInfo> > <rdfs:comment>...</rdfs:comment> > <owl:imports rdf:resource='...'/> > </owl:Ontology> > > This is commonly called the ontology header and is typically found near the beginning of the RDF/XML document.

As noted earlier, it is recommended that the base URI be defined using an xml:base attribute in the <rdf:RDF> element at the beginning of the document. > ]] Brian, Thanks for the comment.
