This is a follow-up of OFFICE-2266:
The ODF ontology files are currently not resolvable at their namespace URI, although this is considered to be best practice according to
Best Practice Recipes for Publishing RDF Vocabularies
http://www.w3.org/TR/swbp-vocab-pub/
which states:

Minimum Requirements
M1. The 'authoritative' RDF description of a vocabulary, class, or property denoted by an HTTP URI can be obtained by dereferencing the URI of that vocabulary, class, or property.

The OASIS policies however require that HTML files that describe a namespace are returned when resolving namespace URIs.
The solution would be to return the ontogy for http requests that contain an
'Accept: application/rdf+xml'
and to return the namespace description in all other cases.
It has to be discussed with OASIS administration if this is possible.
