  5. What is CERIF ? Common European Research Information Format • A Concept about Research Entities and their RelationshipsSpecification (Conceptual Level) • An abstract formal description of the concept about entities and their relationships Model (Logical Level) • A formal machine readable description of the conceptDatabase Scripts (Physical Level) SQL Script ----------------------- CREATE Table Person CREATE Table Project CREATE Table OrgUnit Organisation of Data / Information accordingly !!

  6. What is CERIF ? Common European Research Information Format • data model (conceptual, logical, physical) • allows for a (metadata) representation of • research entities • their activities / interconnections (research) • their output (results) • allows for high flexibility with formal semantic relationships enables quality maintenance, archiving, access and interchange of research information supports knowledge transfer to decision makers, for research evaluation, research managers, strategists, researchers, editors, the general public

  7. What is CERIF ? CommonEuropeanResearchInformation Format • CERIF is an EU Recommendation to Member States http://cordis.europa.eu/cerif/ • The European Commission (EC) has authorised euroCRIS to maintain and develop CERIF and its usagehttp://www.eurocris.org/cerif/cerif-releases/

  33. Discussion • Which entities define the range of the repository (IR) world ? • Person • Project • Organisation • Publication • Are additional CERIF entities required in the repository world ? • Teaching ? • Software, Resources, Media? • Are additional CERIF attributes required? • firstname, nickname, … ? • What are essential relationships in the repository World? • Author, Editor, Reviewer, Metrics ?
