ARTEMIS
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
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

• The workspace GUI allows the designer to define the integration process settings
