As you can see in the examples presented in this chapter, it is possible to model most RDF structures using topic map syntax. In fact, it may be possible to combine the two models. Work has begun that may lead to a possible unification of the models. Representatives from the RDF community and the topic map community have been discussing the best path for possibly unifying the two models. At the very least, it seems possible to further demonstrate interoperability between the models.
In the development of the XTM specification, the XTM Authoring Group has taken a great deal of care in considering RDF capabilities. The ability to handle resources is an excellent example of the bridging of the two models.
