  • i4Life

  • Some linking (R. Page)

  • Linking is usually DB-internal = local

  • This is inefficient.

  • Why Linked Open Data?

    Distributed Web Model using W3C standards (xml, rdf, owl) Machine usable data (automatic analysis & reasoning) Web pages at same identifier (content negotiation)

    Distributed Web Model using W3C standards (xml, rdf, owl) Machine usable data (automatic analysis & reasoning) Web pages at same identifier (content negotiation)

    Anyone can say anything about anything, anywhere Usages that the data providers never anticipated Third parties connect concepts between data sets Particular needs contribute to global achievement

    Anyone can say anything about anything, anywhere Usages that the data providers never anticipated Third parties connect concepts between data sets Particular needs contribute to global achievement

    Flexible to adapt to almost any form of data Information managed at source plus annotated globally Queries and other analysis can combine arbitrary sets of

    data, anywhere and owned by anyone Common and diverse vocabularies can be used together

    and related to each other (creativity, science!)

  • Strategy: 1. Stable Identifiers Now (Semantic Web compatible, http-dereferenceable)

    2. Semantic Web Later ...

  • Identifier patterns?

  • Stability is a management

    decision!

  • Scientific knowledge

    management systems?

  • Discoverable Distributed Dissent & Discourse

  • Fine-granular knowledge curation?

  • LOD is not solution to all.

  • Infrastructure to build on top of it

  • Collaboration must become more efficient
