Transcript of "Federated metadata"

  1. 1. Towards a Federation of Semantic Assets Repositories Vassilios Peristeras vassilios.peristeras@ec.europa.eu
  2. 2. Semantic Assets Repositories!  SEMIC.EU: >500 reusable semantic assets!  SEMIC.EU not a one-of-kind infrastructure anymore!  Several national initiatives to create repositories/ libraries/catalogs of metadata standardsHow could we promote reuse at a European level? 2
  3. 3. The need for federationHow could we promote reuse of semantic assets at a European level? … by enabling a federation of semantic assets repositories !  Cross-querying and discovery should be supported !  Respect the autonomy of each repository 3
  4. 4. How to federate?… by using common semantics to describe asemantic assetWe need a common schema for assets descriptionor an …Asset Description Metadata Schema (ADMS) 4
  5. 5. Asset Description Metadata Schema RDF version of ADMS draft version 0.6!  We are reusing existing vocabularies!  We discuss ADMS with broader communities 5
  6. 6. Asset Description Metadata Schema!  We are reusing existing vocabularies LOD vocabularies reused in ADMS: !  Data Catalog Vocabulary (dcat): http://www.w3.org/ns/ dcat !  Dublin Core (dc): http://purl.org/dc/terms/ !  Friend Of Friend (foaf): http://xmlns.com/foaf/0.1/ !  Description of a Project (doap): http://usefulinc.com/ns/ doap# !  Simple Knowledge Organization System (skos): http:// www.w3.org/2004/02/skos/core# 6
  7. 7. Prototype Proof-of-concept Architecture and Prototype!  Scalability!  Alternative implementations 7
  8. 8. Next Steps!  Refine ADMS and discuss it with Member States and broader communities!  Evaluate the prototype!  Develop a portal as part of the SEMIC.EU infrastructure to support pan-EU federation, querying, browsing of semantic assets 8
