Abstract
In presence of Grid where a huge amount of databases can be involved in sharing cycle, database tools and middlewares should be well suited for schema mediation and query processing in a semantically meaningful way. Dart is an implemented prototype system whose goal is to provide a semantic solution capable of deployment in grid settings. This paper particularly concerns the problems of semantic query answering in DartGrid. Our first contribution is a semantically enriched query language, called Q3, for specifying complex queries using RDF/OWL semantic. We describe its implementation in Dart Database Grid, and also introduce a semantic interface for user to graphically browse RDF semantic, and visually construct Q3 queries. © Springer-Verlag 2004.
