Unlocking Research Metadata Standards and Common Grounds
Explore the world of research metadata, its purpose, common grounds in organizations, and the need for a common metadata format to drive discovery. Learn about CERIF, a comprehensive European research information format, its history, and evolution. Understand the requirements for complete coverage of research information in a machine-processable format.

Presentation Transcript
Contextual Metadata Jan Dvorak CERIF Task Group Leader @ euroCRIS Researcher @ Charles University in Prague, CZ Consultant @ InfoScience Praha, CZ The 2013 euroCRIS Seminar :: September 9-10, 2013 in Brussels, Belgium
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
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
Common Grounds Organisations Universities, Research institutes, Hi-tech companies Funding bodies & organisations Publishers Facility operators People Researchers Management
One Domain Research
Consistency Several possible views of the same objects Inconsistencies would be unprofessional (at the very least)
Common Metadata Format? To drive all the discovery metadata views A lingua franca for research
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
the answer CERIF Common European Research Information Format Common Exchange Research Information Format
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
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
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
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
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
CERIF: Declared Syntax Terms can be misleading Senior researcher vs. Research associate It s the real meaning that matters Definition Description Examples
Research Information Infrastructure Discovery metadata generated from CERIF references Detailed (meta)data
