FOAM - A Framework for Ontology Alignment and Mapping. In this demo we present FOAM, a novel tool for aligning and mapping ontologies. It is based on latest research efforts and shows very promising results. The tool is briefly explained and pointers to actual applications are given. The Framework for Ontology Alignment and Mapping (FOAM) is available through its webpage . On the page one can find links to relevant publications, a download section of binaries and source code, installation guidelines and the documentation of FOAM, and some ontologies to test the tool. Further, there is a web-interface for internet users interested in very shallow testing. For real use we recommend downloading it. Requests for the tool have come from around the world
