  1. Defining and Managing Semantics and Datatypes – Is there a role for ISO 13250 Topic Maps? Martin Bryan Technical Manager The Diffuse Project www.diffuse.org

  2. About The Diffuse Project • 5th framework accompanying measure • Provides a single source for information relating to Information Society standardization initiatives • Provides guides on the role standards can play in business, particularly within R&D projects • Seeks to identify interaction between IST projects and IS standardization

  3. The Diffuse Standards List

  4. CEN/ISSS EC Workshop • CEN's Information Society Standardization System's Electronic Commerce Workshop provides a forum for the discussion of cross-industry issues relating to the use of IST for business messaging • Extends work previously done under the aegis of the European Board for EDI Standardization (EBES)

  5. EC Workshop working groups • XML/EDI (now a separate workshop) • Electronic Commerce Architectures • Preparing overview of existing architectures • Looking at what overall requirements are • Defining and Managing Semantics and Datatypes for Electronic Commerce • Produced CEN Workshop Agreement on Datatyping for Electronic Data Interchange

  6. Role of DAMSAD-EC • Identifying requirements for semantics management within electronic commerce • Monitoring the work of the ebXML initiative's Core Components group • Based on UN/EDIFACT semantics • Expressed using XML syntax • Identifying relationships between relevant initiatives, including ISO BSR, ANSI X.12, UN/EDIFACT and ebXML

  7. ISO/IEC 13250: Topic Maps • Published January 2000 • Based on SGML Architectural Forms • ISO 8879: 1986 Standard Generalized Markup Language (SGML) • ISO 10744:1997 Hypermedia/Time-based Structuring Language (HyTime) • Allows multilingual naming of subjects • Allows identification of relationships between subjects

  8. Topic Maps or RDF? • RDF describes the characteristics of a single resource • Topic Maps describe characteristics known to be shared by a set of resources • RDF points a resource to known semantics (à la library catalogue record) • Topic Maps points known semantics to relevant resources (à la subject group)

  9. Why use Topic Maps for EC? • Need multiple names for business objects • To cope with multilinguality • To cope with domain-specific naming • Need to identify relationships between business objects • One record can serve different purposes when used in different contexts • Need to be able to access record using many different criteria

  10. What can IST do to help? • By identifying the type of relationships that are commonly found to occur between business process • By identifying a multilingual set of names for a business process used within the European single market • By identifying industry specific names for business processes and for the relationships between processes
