Both Topic Maps and RDF (Resource Description Framework) are popular semantic web standards designed for machine processing of web documents. Since these representations were originally created for different purposes, they have conceptual differences in their data models, and therefore have different tools to parse, store, and query them. However, there are more tools to handle RDF data than those existing for Topic Maps. The authors' approach is to map Topic Maps to a view expressed in RDF and then query this view by the RDF query language SPARQL.
