Information integration system over sources that are distributed and possibly heterogeneous.

In PICSEL 3, the mediation architecture of the information integration system is hybrid. The mediator also integrate a local data warehouse which contains data given by content providers. These data are conform to the mediator schema represented in RDFS+ language (RDFS extended by a fragment of OWL-DL). The data warehouse will be progressively enriched by external data.
One of the main goals of PICSEL 3 is the semantic treatment of the mediator answers. More accurately we want to study the references reconciliation problem in order to eliminate redundancies and to fusion data coming from different sources.
Another goal is to propose an approach where wrappers aon integration systemre built semi-automatically.
