This book contains a collection of thoroughly revised tutorial papers based on lectures given by leading researchers at the Second International Summer School on the Reasoning Web in Dresden, Germany, September 3-7, 2007. The objective of the book is to provide a coherent introduction to Semantic Web methods and research issues with a particular focus on reasoning.

The nine tutorial papers presented provide competent coverage of methods and research issues of the Semantic Web, ontology languages and their relation to description logics, Web query languages, XML, RDF and Topics Maps, evolution and reactivity, personalization in the Semantic Web, rule modeling with UML, techniques in Web information extraction, employing ontologies to ease construction of software applications, and type checking for Web rule and query languages.

This book constitutes the thoroughly refereed joint post-proceedings of nine workshops held as part of the 10th International Conference on Extending Database Technology, EDBT 2006, held in Munich, Germany in March 2006.

The 70 revised full papers presented were selected from numerous submissions during two rounds of reviewing and revision. In accordance with the topical focus of the respective workshops, the papers are organized in sections on database technology in general (EDBT PhD Workshop), database technologies for handling XML information on the Web (DataX 2006), inconsistency and incompleteness in databases (IIDB 2006), information integration in healthcare (IIHA 2006), semantics of sequence and time dependent data (ICSNW 2006), query languages and query processing (QLQP 2006), pervasive information management (PIM 2006), pattern representation and management (PaRMa 2006), and reactivity on the Web.
