The Extensible Markup Language (XML), a W3C standard since 1998, allows the uniform representation of semistructured documents and data, readable for humans as well as for machines. XML is used as universal data and document format throughout all application areas of computer science. While XML describes syntax, the resource description framework (RDF) and the web ontology language (OWL) can code the semantics, i.e., meaning in a formal way, so that it can be processed automatically, e.g., for inferring knowledge from several facts or more generally answering complex queries.

The first part of the lecture covers the actual XML standards (XML, XML-Schema, XPath, XSL and XQuery), the second part gives an introduction to the basic semantic web technologies (RDF, OWL). The focus of the lecture is on practical knowledge about the usage of these technologies and the theoretical concepts behind them.

This lecture will be an expanded version from the lecture of last summer term.
