Please note that the service cannot convert arbitrary RDFa + HTML pages into a topic map. You need to specify a mapping. And the mapping file <http://mappify.googlecode.com/svn/sandbox/example/rdfa.crtm> maps just a subset of the GoodRelations tiples to Topic Maps (plus some FOAF / common RDF triples). Further, the mapping is not very useful since it uses PSIs like <http://psi.example.org/offerer> which do not exist. Users may provide mappings either in an RDF format [1] or in CRTM [2].
