A GRDDL profile for topic maps: a possible transformation from XTM to RDF/XML

Hello,

In the eWok project [1] we are working with users who draw their schemas 
and annotations using topic maps. We proposed a transformation to 
RDF/XML  and turned it into a GRDDL profile for XTM.

Here is an example of topic maps in XTM:
http://www-sop.inria.fr/edelweiss/people/Priscille.Durville/docs/hamlet.xml

Here is the profile we use for XTM:
http://ns.inria.fr/grddl/xtm/

Here is the GRRDL result:
http://www.w3.org/2007/08/grddl/?docAddr=http%3A%2F%2Fwww-sop.inria.fr%2Fedelweiss%2Fpeople%2FPriscille.Durville%2Fdocs%2Fhamlet.xml&output=turtleplain

Here is the GRRDL result as a graph:
http://www.w3.org/RDF/Validator/ARPServlet?URI=http%3A%2F%2Fwww.w3.org%2F2007%2F08%2Fgrddl%2F%3FdocAddr%3Dhttp%253A%252F%252Fwww-sop.inria.fr%252Fedelweiss%252Fpeople%252FPriscille.Durville%252Fdocs%252Fhamlet.xml%26output%3Drdfxml&PARSE=Parse+URI%3A+&TRIPLES_AND_GRAPH=PRINT_GRAPH&FORMAT=PNG_EMBED

*Important note* :  we were unable to use the XTM namespace for two reasons
(1) the www.topicmaps.org server was down for several weeks preventing 
us from running the GRDDL service on the XTM sample since the namespace 
of XTM includes this server.
(2) when the sever came back to life, the document it serves when called 
on the namespace does not have the right encoding and thus crashes the 
GRDDL service.
If I remember well there is no way to indicate you don't want to follow 
the URL of a namespace thus for this demo we had o use a different 
namespace.
