A widely acknowledged obstacle for realizing the vision of the Semantic Web is the inability of many current Semantic Web approaches to cope with data available in such diverging representation formalisms as XML, RDF, or Topic Maps. A common query language is the first step to allow transparent access to data in any of these formats. To further the understanding of the requirements and approaches proposed for query languages in the conventional as well as the Semantic Web, this report surveys a large number of query languages for accessing XML, RDF, or Topic Maps. This is the first systematic survey to consider query languages from all these areas. From the detailed survey of these query languages, a common classication scheme is derived that is useful for understanding and differentiating languages within and among all three areas. This revision of deliverable I4-D1 extends that deliverable by a refined version of the presented material that has been published as a chapter in the LNCS tutorial volume for the REWERSE "ReasoningWeb" 2005 summer school as well as short outlooks on further refinements of the material for upcoming tutorials and summer school courses.
