Reciprocal relation output with RDF/XML
Hi all,
is there any insight, if there are reciprocal connections between two
things (like with dct:references and dct:isReferencedBy), how Jena
weighs in the one against the other when creating the "pretty" XML
output from a SPARQL query ?
Currently my results appear to "tilt" from one view to the other,
obviously somehow depending on the data contained – and thereby
completely ignoring the hierarchy assumed by the SPARQL‘s "construct"
section.
Is there any documentation on enforcing a particular "perspective" on
the result (if possible at all…) ?
The output is to be processed by an XML-based website system – and
parsing "plain" RDF/XML is not an option there.
As always, any hints are highly appreciated.
Best,
Bardo

Maybe you should provide some examples?

Thank you very much, Dave; especially for the link.
And indeed, "ambitious" appears to be the appropriate term for it… ;-)

The abbrev format does it's best but if you want the XML stable enough
to parse easily then you may be better off with non-abbrev. Even then
it's an ambitious goal.
