seeing what Nikita said I've attached a first effort I had with the
definition of one in terms of the other and vice versa. This is strawman
effort and I'll continue to evolve it.

cheers,

<!--

Are topics maps at the rdf schema level?

TM constructs are at this level and tm instances are rdf instances that adhere to the rdf:topic map schema

-->

<!-- Core Topic Map Classes -->

<rdfs:Class ID="http://www.topicmaps.com/rdf-schema/Topic/v1.0">
	<rdfs:label xml:lang="en">Topic</rdfs:label>
