Abstract
Access to Web data has become an integral part of many applications and services. In the past, such data has usually been accessed through human-tailored HTML interfaces. Nowadays, rich client interfaces in desktop applications or, increasingly, in browser-based clients ease data access and allow more complex client processing based on XML or RDF data retrieved through Web service interfaces. Convenient specifications of the data processing on the client and flexible, expressive service interfaces for data access become essential in this context. Web query languages such as XQuery, XSLT, SPARQL, or Xcerpt have been tailored specifically for such a setting: declarative and efficient access and processing of Web data. This tutorial introduces, compares, and classifies the most relevant exemplars of Web query languages for XML, RDF, and/or TopicMaps data. Interesting features as well as differences in expressiveness and adequacy are digested along practical and concrete use cases. Emphasis is placed on recent W3C standardization activities, contrasted with alternative approaches from industry and academia.
