The ARTEMIS functionalities: 

The ARTEMIS functionalities Wrapping semistructured source schemas into ODLi3 representation Loading ODLi3 source schemas Set-up/import of a thesaurus of terminological relationships and inter-schema properties for schema matching Affinity-based analysis of source schemas (combination of several affinity coefficients) Clustering of schema elements and construction of the affinity tree Interactive selection of candidate clusters and cluster storage Interactive creation of global classes and associated mapping rules out of clusters through unification rules

ARTEMIS Demo: 

ARTEMIS Demo New functionalities for XML datasource management X-formalism model, for conceptual representation of XML schema descriptions (e.g., DTDs) Wrapper module for DTD-to-X-formalism and for X-formalism-to-ODLI3 translations Unification rules for XML datasources Importation of the Common Thesaurus provided by MOMIS
