Topic maps and the Resource Description Framework (RDF) are two independently-developed proposals for the representation, interchange and exploitation of model-based data on the World Wide Web. Each proposal has established its own user communities. Each of the proposals allows data to be represented as a graph with nodes and labeled arcs which can be serialized in one or more XML- or SGML-based syntaxes. However, the two data models have significant conceptual differences. A central goal of both proposals is to define a format for the exchange of knowledge on the Web. In order to prevent a partition of the Web into collections of incompatible resources, it is necessary to investigate ways to integrate topic maps and RDF data. This paper presents a first step by representing topic maps as RDF data and thus allowing topic maps to be queried by an RDF-aware infrastructure. We achieve this by mapping a topic map graph model to the RDF graph model. All information from the topic map is preserved, such that the mapping is reversible. The mapping is performed by modeling the graph features of a topic map graph model with an RDF graph. The result of the mapping is an RDF-based representation of topic map data that can be queried as an RDF data source by an RDF-aware query processor.
