  2. Research Metadata • Discovery metadata for information to be found • Serve many specific use-cases, scenarios, niches • Many standards • Tens of major ones • Hundreds of domain-specific standards • … • Thousands on experiment-level

  3. The Purpose of Metadata • Enable the re-use of resources • Knowledge stored in publications • Data in datasets • Functionality in software • Participation in events • Infrastructure • Facilities • Equipment • Services

  4. Common Grounds • Organisations • Universities, Research institutes, Hi-tech companies • Funding bodies & organisations • Publishers • Facility operators • People • Researchers • Management

  5. One Domain Research

  6. Consistency • Several possible views of the same objects • Inconsistencies would be unprofessional (at the very least)

  7. Common Metadata Format? • To drive all the discovery metadata views • A lingua franca for research

  8. Requirements • Complete coverage of research information • Interlinked: the context • Allow for many perspectives on the research information • Accommodate multilinguality: support translations • Accept the world keeps changing: record history • Declared semantics: definitions rather than terms • Formal syntax – machine processable & understandable

  9. … the answer CERIFCommon European Research Information FormatCommon Exchange Research Information Format

  10. CERIF: a concise history • CERIF91 – flat file • CERIF 2000 – database structured • CERIF 2006 – semantics moved into Semantic Layer • XML exchange format • CERIF 1.5 (2012) – federated identifiers • XML exchange format polished • CERIF 1.6 (2013) – datasets supported

  12. CERIF: Many Perspectives • Start from any entity: • Project – funding, consortium, project team, outputs • Publication – authors, publisher, funding • Research dataset – creator/contributor, origin project, publications that build upon it • Person – outputs, datasets, projects, events, … • … • A mesh, a fully connected graph

  13. CERIF: Multilinguality • Any free-text attribute is treated as: • Possibly multi-valued • Each value qualified with • Language code • Translation mode • Original value • Human translation • Machine translation

  14. CERIF: Interlinking • (Almost) any entity connected to any other entity • Most entities connected to itself • “is-part-of / has part” • “builds upon / is used by”

  15. CERIF: Record History • Every relationship records the time interval in which it is/was/will be true • Open ends represented by effective ±∞ • When something changes: • the old relationship is not removed, only its end date is set • a new relationship is inserted, starting now • Historic data accumulates

  16. CERIF: Declared Syntax • Terms can be misleading • Senior researcher vs. Research associate • It’s the real meaning that matters • Definition • Description • Examples
