* Data model influences design of
 
** data publication formats
 
** programmatic interfaces
 
* Data model also determines management and maintenance strategies and procedures
 
* Data model often implicit in a standard, not formally specified …
 
** E.g. BS 8723, ANSI Z39.19
 
* Some ‘standards’ to consider …
 
** ANSI Z39.19, BS 8723
 
*** "Traditional thesaurus" ...
 
*** model described in prose by BS 8723, ANSI Z39.19
 
*** Only terms reified, concepts implicit
 
 
 
** SKOS Core
 
*** Explicitly concept-oriented data model
 
*** Specified formally using RDFS/OWL
 
 
 
** OWL
 
*** Class/instance-oriented model (“ontologies”)
 
*** Formally specified via model-theoretic semantics
 
 
 
** TMF - Terminology Markup Framework ISO 16642 (ISO TC 37)
 
*** Concept-oriented
 
*** Specified using UML
 
*** Really a framework for designing XML formats
 
 
 
** ISO Topic Maps
 
*** Topics, Associations, Occurrences, Roles...

Comments:
 
* ANSI Z39.19, BS 8723, SKOS Core, TMF broadly aligned …
 
* (I.e. T-O vs. C-O not necessarily at odds)
 
**  however N.B. choice of T-O vs. C-O model as foundation has implications for management/maintenance and URI use.
 
* Relationship to ontologies (OWL) … ?
 
* Topic maps … ?

Action Points for the Following Year

The following points are based on a presentation by Alistair Miles at the 2005 Berlin Ecoinformatics meeting.

Identity

Construction

Data Model

Publication

  • General principle: publish data
  • XML
    • Thesaurus tradition (e.g. Zthes …)
    • Terminology (I.e. TC 37) tradition (e.g. TBX, implementation of TMF)
    • Topic maps tradition … XTM
  • RDF
    • SKOS Core
    • RDFS/OWL
  • OWL
    • Based on RDF
    • Ontologies for the web
    • W3C recommendation
  • Comments
    • N.B. XTM and anything based on RDF (I.e. SKOS Core, OWL) designed for a distributed information environment
      • I.e. use URIs, support data linking, merging
    • Others not (designed for point-to-point transfer)

Services

  • Service Oriented Architecture (SOA)
    • Important software engineering paradigm
  • Web services
    • WSDL, SOAP (W3C)
  • Web service interface to conceptual/terminological resource …

Lots of individual projects (EOS, UNEP.Net …)

  • Standardisation initiatives …
    • Some recent work on implementing the SKOS API …
    • … but still plenty of issues.
    • OMG lexicon query service?
    • HL7 Common Terminology Services (CTS)
    • ANSI terminology services API?
    • XMDR?
    • Other attempts to build consensus?
  • N.B.
    • SOA & WS architecture for distributing programmatic components
    • Semantic Web machinery architecture for distributing data
    • Complementary
      • E.g. a service that provides efficient programmatic access to an aggregation of data harvested from multiple published sources
