  1. BIS TDWG Conference, New Orleans 2011 Knowledge Organization Systems Session - Introduction Éamonn Ó Tuama Senior Programme Officer, Inventory, Discovery, Access (IDA) Global Biodiversity Information Facility (GBIF) 20 October 2011

  2. KOS symposium Introduction: the GBIF context (Éamonn Ó Tuama) GBIF KOS task group report (Bob Morris) The GBIF KOS work programme: prioritised requirements and proposed solutions (Dag Endresen) BioPortal as an ontology management system (Hilmar Lapp) The TDWG Vocabularies (Greg Whitbread) Managing the Darwin Core set of terms (John Wieczorek)

  3. Knowledge Organization Systems ... to manage the vocabularies used for sharing biodiversity information. - Term lists: glossaries, dictionaries, gazetteers - Classifications / categorizations: taxonomies e.g., Dewey Decimal Classification - Relationships: thesauri, ontologies simple relationships a model of a domain Hodge G. 2000. Systems of Knowledge Organization for Digital Libraries: Beyond Traditional Authority Files. http://www.clir.org/pubs/reports/pub91/contents.html

  4. Darwin Core – a glossary of terms higherClassification coordinatePosition specificEpithet geodeticDatum collectionCode taxonConceptID taxonRank collectionCode: The name, acronym, coden, or initialism identifying the collection or data set from which the record was derived. Examples: "Mammals", "Hildebrandt", "eBird".

  7. Need for KOS - lack of vocabularies/ontologies (eBiosphere) - requirement for principles and best practices for developing ontologies (TDWG 2009) - advance the TDWG ontology architecture (TDWG 2009) - tools for TDWG Interest Groups to support standard development process (TDWG 2009) - recognition that not everyone has to be an ontologist - use of human readable vocabularies + ontology proper (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)

  8. GBIF position paper on KOS Robert A Morris Terry Catapano Donald Hobern Hilmar Lapp Norman Morrison Natasha Noy Mark Schildhauer David Thau

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

  10. GBIF Vocabularies Service Audubon Core extension to Darwin Core

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

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

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