I concur. Moreover, even without cacheing 303s, if each document  
includes an owl:imports, and/or  a rdfs:isDefinedBy for the subject  
term, and a client decides to follow those links, they will find the  
rest of the terms and can cache that and not need to fetch the rest.  
An an example of this approach, here is a prototype I am working on  
for the OBI ontology. http://purl.obofoundry.org/obo/OBI_0000225

The intention is that each page organized around returning useful  
enough information about a single term in the ontology - exactly what  
is a judgement call. Each has an owl:imports statement so that clients  
that need the correct semantics are able to retrieve them, and there  
are rdfs:isDefinedBy statements for the main term, as well as any  
terms that I have borrowed from ontologies that are not, as yet, OWL  
DL (barring oversights - that's the intention).

Status of prototype: Only one of the html pages exists, and it is not  
yet generated with hyperlinks. RDF/XML is available for only classes  
in the ontology at the moment, not properties. There is an unresolved  
issue regarding mime-types: application/rdf+xml doesn't trigger use of  
the stylesheet, so the page is served as application/xml (shouldn't  
every application/rdf+xml also be a application/xml ?)
