Both Topic Maps and the W3C Semantic Web technologies are meta-level semantic maps describing relationships between information resources. Previous attempts at interoperability between XTM Topic Maps and RDF have proved problematic. The ISO’s drafting of an explicit Topic Map Data Model combined with the advent of the W3C’s XML and RDF-based Description Logic-equivalent Web Ontology Language now provides the means for the construction of an unambiguous semantic model to represent Topic Maps, in a form that is equivalent to a Description Logic representation.

This paper describes the construction of the proposed TMDM ISO Topic Map Standard in OWL DL (Description Logic equivalent) form. The construction is claimed to exactly match the features of the proposed TMDM. The intention is that the topic map constructs described herein, once officially published on the world-wide web, may be used by Topic Map authors to construct their Topic Maps in OWL DL.

The advantage of OWL DL Topic Map construction over XTM, the existing XML-based DTD standard, is that OWL DL allows many constraints to be explicitly stated. OWL DL’s suite of tools, although currently still somewhat immature, will provide the means for both querying and enforcing constraints. This goes a long way towards fulfilling the requirements for a Topic Map Query Language (TMQL) and Constraint Language (TMCL), which the Topic Map Community may choose to expend effort on extending. Additionally, OWL DL has a clearly defined formal semantics (Description Logic ref).

The first priority of H-maps is the simplicity of usage. Hereby issues of technology and science can be dealt effectively – while ensuring consistent compliance with the Topic Maps standards.
