Graphical representation of Annotation propreties

Greetings,

I'm reusing "the Web Annotation ontology" to develop a new ontology in the
elearning domain.

I'm using Protege 5.2 under Windows as ontology editor. I'm having the
problem of depecting my new ontology graphicaly. The problem is that
OntoGraph (Protege's plugin ) dosen't work with "Annotation propreties"
like oa:hasTarget, oa:hasBody and dcterms:Creator.

Best Regards
