The growing amount of distributed data over the internet leads to increasing needs for interoperability. Being able to take into account the meaning of information is a real challenge for suitable data sharing. The semantic web and the ontologies are relevant technologies to provide semantic cooperation of heterogeneous sources. We propose a complete architecture OWSCIS (Ontology and Web Service based Cooperation of Information Sources) which allows to query a cooperation of information sources. The semantic of the local data is expressed using local ontologies which are mapped to a reference ontology. This reference ontology can be queried by an end user to transparently access the cooperation. The different components of the architecture are described: the data providers, the knowledge base, the inter-ontology mapping process, the visualization service and the querying service. A special focus is done on the latter service.
