CERIF Interoperability and LOD Miguel-Angel Sicilia TG LOD leader, euroCRIS

Interoperability: levels and purposes Transferring from one place to another or combining information while retaining meaning Different levels: syntactic, semantic, etc. Two important facts: – Semantics are in the CERIF model – The LOD is not adding by itself any semantics, only exposing in a different format. So the LOD “ontologies” are no other thing than a RDF expression of CERIF. – Improvement in semantics should go either directly to the CERIF relational model or to some “extended” ontology

Reasons to share CERIF data For the benefit of the public – Applications collecting maps of science combining heterogeneous sources of information. For intelligent applications – Applications relating patterns of scientific production with the geospatial or disciplinary structure of countries. For partners that need the data transferred for internal processing – E.g. the National Agency asks a University for the journal publication production per Department to benchmark and assign funding. – E.g. the EU needs project outcomes data. For partners that need on-line access to data. – E.g. a third party creates a Gmail extension that shows you some information on your contacts by accessing public RIS on-line. For translating data between schemas – E.g. to translate CERIF data into VIVO RDF.

TG LOD This year: – VOA3R implementation (excl. bibliographical data). – Specs revised and augmented by ENGAGE. – Mapping of VIVO and CERIF at the CERIF model level. To-do: – Publish the base ontologies (and VIVO mapping?) in EuroCRIS domain. – Finalize and publish the LOD recommendations. – Publish the package to expose CERIF data as LOD using D2RQ (config. Files + install manual).
