Abstract

XQuery is a query language designed to allow queries across the many kinds of information that are represented in XML. Although topic maps and RDF can also be represented in XML, many have held that their many possible syntactic forms make them extremely difficult to query using an XML query language, and that they can only be queried using special-purpose query languages with built-in knowledge of their semantics, including the ability to exploit RDF schema information. This talk shows that XQuery can, in fact, be used to solve the kinds of queries for which RDF and topic map query languages were designed, though with a loss of type safety.
