Knowledge Organization Systems
- Term lists: glossaries, dictionaries, gazetteers
- Classifications / categorizations: taxonomies
- Relationships: thesauri, ontologies
... to manage the vocabularies used for sharing biodiversity information.

Need for KOS
- requirement for principles and best practices for developing ontologies (TDWG 2009)
- lack of vocabularies/ontologies (eBiosphere)
- advance the TDWG ontology architecture (TDWG 2009)
- tools for TDWG Interest Groups to support standard development process (TDWG 2009)
- collaboration on ongoing support mechanisms for essential shared vocabularies (GBIF LGTG Report)
- hackathon to merge Darwin Core with existing TDWG ontologies and current GBIF vocabularies work (GBIF LGTG Report)
- recognition that not everyone has to be an ontologist - use of human readable vocabularies + ontology proper (TDWG 2009)

GBIF Vocabularies Service
Mapping tools for a range of community-supported vocabularies and Darwin Core extensions

GBIF Vocabularies Service
Audubon Core extension to Darwin Core

- New dedicated position at GBIF (Dr Dag Endresen) funded through external projects (ViBRANT, i4Life)
KOS activities at GBIF
- Review GBIF Vocabularies Service and related systems -> develop vocabulary management system
- Engage with wider community: - participation in Dublin Core workshop, Sept 2011- KOS symposium at TDWG 2011 Conf, Oct 2011
- Review recommendations in KOS task group report and develop implementation roadmap
Key requirement: a platform to support the development, maintenance and governance of vocabularies for the biodiversity community

DCMI Vocabulary Workshop
- Very keen to collaborate with TDWG and share experience
- No turn-key solution
Den Haag, 21 Sept, 2011
- Managing a forum in which community can focus on issues around management of vocabularies and develop best practices

Key issues
1. Establishing a community site for managing our vocabularies
2. Central role of TDWG TAG
3. Whither the TDWG vocabularies site?
4. Whither the TDWG vocabularies?
5. Relationship of DwC to TDWG vocabularies
6. Separating term definitions from modeling
7. Introducing semantics in DwC: identifying classes – a good idea?
8. Need for a high level conceptual model?
