Abstract:
In recent years, there has been a growing interest in semantic integration in the Semantic Web environment, whose goal is to access, relate and combine knowledge from multiple sources. The need of integrating the semantics from relational data sources into this environment, therefore, has also emerged. However, there is one important aspect of database schemas that OWL up to now has not captured yet, namely identification constraints. To address this problem, this paper introduces a decidable extension of OWL-DL, namely OWL-K, that supports such constraints.
