Wrap up  Matching  Geometry  Semantics  Multiscale modelling / incremental update / generalization  Geometric algorithms  Web Services

Discussion groups  Web Services:  From ideas to implementations  New issues about standards to follow  Discussion of usage continues...  Geo-Ontologies:  Different views about terminology (semantics, schema, ontology,...)  Need for further research

Wrap up What have we learnt? “Ontologists”  Provide abstract formal concepts  Need implementation /go from knowledge base to to database  Automatic extraction / annotation of metadata “Geometrists”  We need to go beyond the schema integration  Need tools for ontology editing and matching  Semantics is required for web services that understands more than algorithms

Thank you for your attention!!
