  3. Ontologization • ontology-based reformulation • Most current standards are based on XML and lack formal metamodeling tools. • not XML but RDF as base description and modeling tool • Semantic interpretation is standardized not for XML but for RDF. • something like N3 for textual representation • ontology as schema • not DTD, XML Schema, RELAXNG, etc.

  4. Motivations of Ontologization • Lack of formal tool by which to write schemas fully addressing the specifications. • DCR model lacks descriptive power.

  5. Discussion • What’s essential is the graph model. • Textual representation is not essential. • But people tend to specify XML representation, etc. W3C insist on plain-test encoding.

  6. 2nd Day • Purposes of ontology, taxonomy, data model, etc.? • CAOS vs. TDG6 Sem. Roles? • A concept is a conjunction of characteristics. … partial equivalence • DC schema and ontology are different. • But DC metamodel may be defined as an ontology.

  7. Resolutions • TDG6 appoints Paul Buitelaar to launch and lead the project for ontologizing LMF, collaborating with Nicoletta Calzorali and other experts.
