Hi:

We are trying to generate a set of consistent XML documents using the 
"RDF/XML-ABBREV" format.

Our problem is dealing with resources having multiple RDF types and selecting a 
given type to be used as the typed node in an RDF/XML serialization. It seems 
that the RDF/XML writer selects randomly which type to use.

We attempted to use the "prettyTypes" property [1] to control the output but 
this seems only to affect the sort order and not the selection of which RDF 
type to use.

Ideally we would like to generate XML of the form:

    ...
     <ex:A rdf:about="...">
       ...
       <rdf:type rdf:resource="{ex:B}"/>
       ...
    </ex:A>
    ...

where RDF type ex:A is used for the typed node in preference to RDF type ex:B.

Is this even possible within the Jena API?

(This is important to us in treating these RDF/XML documents within an XML 
context (where element naming is preserved) rather than just using RDF/XML as a 
transfer syntax.)

Thanks,

Tony
