  • Ifresources are marked up withsemanticallydefined and machinereadableconcepts, they can belinked and mashed up preciselyaswehaveseen in the examplefrom the BBC.In thisexamplewe start withan AGRIS record on Hazardouswaste, whichisindexedwith AGROVOC. Alreadynowwe can easily link to material indexedwithEurovoc, hereanexamplefromEuroLex. If the UNBIS thesaurus wouldberestructuredto a conceptscheme and publishedas LOD, related UN documentscouldbeattachedautomaticallyby the machine.
  • How does this work: A resource is connected with each concept URI in the web. The concepts between three vocabularies are having same literal which is connected with owl:sameAS/exactMatch relationship. As we are speakingaboutthesauri and notontologieswekept the relation tobechosenpurposelyvague. The conceptscouldbematchedwithowl:sameAS or the termscouldbematcheswith SKOS:exactMatch. A lotofdiscussion on thisisongoing

  • AGROVOC – Linked Open Data
    A Corner Stone for an Information Management Infrastructure in Agricultural Research and Innovation

    Tappingthe potential ofLinked Open Data
  • We will promote research for food and agriculture, including research to adapt to, and mitigate climate change, and access to research results and technologies at national, regional and international levels.
    We will reinvigorate national research systems and will share information and best practices.
    We will improve access to knowledge.

  • Vocabularies and LOD
    Simply publishing your data as RDF does not link them to other data sets 
    Creating this links by humans is interesting in detail, but unrealistic as mass processing
    Linking 2 standard vocabularies can link 200 datasets which use these standard vocabularies
