Overview

This volume constitutes the proceedings of the joint VLDB workshop on the SemanticWeb,OntologiesandDatabases(SWDB-ODBIS2007),co-locatedwith the 33rd International Conference on Very Large Data Bases VLDB 2007. In 2007,organizersoftheSemanticWebandDatabases(SWDB)andtheOntologies based techniques for DataBases and Information Systems (ODBIS) workshops decided to join forces in order to further integrate these important areas of research. Research on the semantic web and on ontologies has reached a level of ma- ritywheretherelationshipwithdatabasesisbecomingofparamountimportance. The objective of this joint workshop was to present databases and information systems research as they relate to ontologies and the semantic web, and more broadly, to gain insight into the semantic web and ontologies as they relate to databases and information systems. The workshop covered the foundations, methodologies and applications of these?eldsfordatabasesandinformationsystems.Thepaperspresentedfocused on foundational or technological aspects as well as on research based on expe- ence and describing industrial aspects of various topics such as semantics-aware data models and query languages; ontology-based views, mappings, transfor- tions, and query reformulation; or storing and indexing semantic web data and schemas. This volume includes a selection of extended versions of papers presented at the workshop.
