Abstract

Mediators used to be developed as monolithic systems that envelop the data source's information, such as its semantics and location. Furthermore, its architecture based on wrappers involves a high degree of coupling among the mediator's components. This coupling does not allow sharing services with other organizations or the dynamic integration of new data sources. We have proposed an architecture for conceptual mediation, which allow users to make more expressive queries and infer information from the ontology-explicit knowledge, enabling them to solve queries that a traditional mediator could not evaluate. This architecture also provides a way to achieve not only dynamic integration, but also interoperability between users/applications in the Semantic Web context by means of Semantic Fields. The latter is the focus of this paper.
