TDWG VoMaG Vocabulary management workflow, 2013-10-31 TDWG VoMaG Vocabulary management workflow, 2013-10-31 Presentation Transcript

  •     A framework for managing vocabularies Outcomes of the TDWG Vocabulary Management Task Group TDWG 2013 Annual Conference, Florence, Italy Dag Endresen*, Éamonn O Tuama, Gregor Hagedorn and Steve Baskauf * GBIF-Norway, Natural History Museum of the University in Oslo Global Biodiversity Information Facility (GBIF) 31 October 2013
  • VoMaG  report   Three  main  sec,ons   •  Status  of  the  TDWG  ontology   •  Seman4c  MediaWiki  as  a  development   pla<orm   •  Requirements  for  a  framework  for   managing  vocabularies

  • Vocabulary  management   • Vocabularies/ontologies  are  one  of   the  three  core  components  in  the   TDWG  technical  architecture.  
  • Vocabularies/ontologies   • Provide  a  shared  understanding  of   what  we  mean  when  describing   biodiversity  en44es.   • What  kind  of  thing  or  property.   • A  list  of  things  we  as  a  community   can  agree  upon  the  meaning  of.   • “Concept  repository”  with  terms   iden4fied  by  URIs.   TDWG Technical Roadmap 2008. (TDWG TAG, convened by Roger Hyam).
  • Vocabulary  governance   •  Development,  management  and   governance  remain  a  challenge.   •  Maintenance  requires  efforts.   •  Challenge:  Lack  of  resources  -­‐  No  TDWG   Ontology  coordinator  (since  2007).   •  Experiment:  Possible  as  a  collabora4ve   community  approach  coordinated  using   a  Seman4c  Wiki…???  
  • Term  Wiki   http://terms.gbif.org/wiki/
  • Concept  vocabularies   •  Collabora4ve  development  of  terms  at:   h[p://terms.gbif.org/wiki/  [?  terms.tdwg.org/wiki/  ?]   •  Terms  grouped  into  “concept   vocabularies”  each  controlled  by  a   TDWG  task  group.   •  REUSE  terms  (and  term  URI)  whenever   possible!!  
  • Data  standards   Important principle: Re-use of terms from standardized terminologies wherever possible. 9 The cartoon is from XKCD: http://xkcd.com/927/ CC-BY-NC
  • Term  versus  Concept   “The SKOS (simple knowledge organization system) format is designed to present KOS data in a format that is suitable for machine inferencing and particularly for use in the Semantic Web (….) concepts – units of thought – and distinguishes these from the terms that are used to label these concepts.

  • Vocabularies/ontologies   • What  kind  of  thing  or  property   •  Concept  (skos:Concept)   • Reused  as:   •  Class  (rdf:Class)    [?]   •  Property  (rdfs:Property)   •  Controlled  element  values  
  • Why use a flat vocabulary ? •  Maximize the reuse of terms, focus on the definition and labels for basic terms. •  Low threshold for non-technical biologists and biodiversity domain experts to access terms and contribute (compared to richer ontologies). •  Preferred technology: RDF (resource description framework) and SKOS (simple knowledge organization system). •  Construction and maintenance of OWL ontologies are demanding in respect to expertise, effort and costs. •  Maintaining SKOS vocabularies are less demanding. •  RDF resources are designed to be easily extended. •  Ontologies (OWL) can be based on (extend) terms declared by a RDF/SKOS vocabulary. •  SKOS became a W3C recommendation in 2009. 12

  • Vocabulary  repository   •  Establish  a  repository  for   “concept  vocabularies”.   •  Example  at:          h[p://rs.gbif.org/terms/          [?  rs.tdwg.org/terms/  ?]   Photo CC-by-3.0 by Hannes Grobe/AWI.

  • Work-flow for Vocabulary management 1.  Mint and maintain concepts and terms, in domain-expert working groups. Using e.g. the http://terms.gbif.org/wiki/ as a collaboration platform. 2. Release final version as a Concept Vocabulary. E.g. publish vocabulary at the GBIF or a TDWG Resources Repository. REUSE terms from published concept vocabularies and other ontologies when designing new application schema such as DwC-A controlled term and value vocabularies. Term Wiki For vocabulary development http://terms.gbif.org/wiki/ 15 Concept Vocabulary (rdf, skos) Resources Repository http://rs.gbif.org/terms/
  • Example: master SKOS/RDF resource en [ es [ zh [ ja [ 16 http://rs.gbif.org/terms/dwc/dwc_translations.rdf
  • Biodiversity ontology development Concept Vocabulary (rdf, skos) REUSE terms from concept vocabularies whenever possible. Ontologies (rdf, owl) Biodiversity ontology repository. 17
  • BioPortal ontology repository A biodiversity “slice” was established at the NCBO BioPortal. •  Loading biodiversity ontologies into the NCBO BioPortal promotes mapping (and reuse of terms) between bio-medical and biodiversity ontologies. h9p:// bis.bio por 18 tal.bioo ntology .org/on tologie s?filter =BIS
