Hey, I'm developing a very simple ontology in Protégé 3.0. Just to
give a brief introduction to the case: the three main classes are
Course, University and ProgrammeAI. There are properties/relations
between the classes, for example "Programme (hasCourse) Course" ,
"Course (isCourseOf) Programme" and "ProgrammeAI (isProgrammeOf)
University". I want to use XSLT to be able to retrieve and show, in
HTML, different views of this data, for instance "which Courses are
part of which ProgrammeAI" or "which Courses can be found at which
Universities".
The main problem about RDF processing with XSLT is that the latter (due
to it's use of XPath) is too dependent on structure, while RDF is a
model that can be expressed in more than once structures. For example,
<a1:Human rdf:about="http://geekologue.com/ppl/manos"; a1:name="Manos"
a1:surname="Batsis" />
is the same as
<a1:Human rdf:about="http://geekologue.com/ppl/manos"; a1:name="Manos">
<a1:surname>Batsis</a1:surname>
</a1:Human>
or it could even be the same as
<rdf:Description rdf:about="http://geekologue.com/ppl/manos";>
<rdfs:instanceOf rdf:resource="&a1;Human"/>
<a1:name>Manos</a1:name>
<a1:surname>Batsis</a1:surname>
</rdf:Description>
etc. So it becomes very difficult to process a model with a structure
based tool like XPath/XSLT.
