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 KOS symposium 1. Introduction: the GBIF context (Éamonn Ó Tuama) 2. GBIF KOS task group report (Bob Morris) 3. The GBIF KOS work programme: prioritised requirements and proposed solutions (Dag Endresen) 4. BioPortal as an ontology management system (Hilmar Lapp) 5. The TDWG Vocabularies (Greg Whitbread) 6. Managing the Darwin Core set of terms (John Wieczorek) 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.

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?
