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

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)

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

-* 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 … ?
