Research metadata

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

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

Common Grounds

  • Organisations

    • Universities, Research institutes, Hi-tech companies

    • Funding bodies & organisations

    • Publishers

    • Facility operators

  • People

    • Researchers

    • Management


One domain

One Domain

Research


Consistency

Consistency

  • Several possible views of the same objects

  • Inconsistencies would be unprofessional (at the very least)


Common metadata format

Common Metadata Format?

  • To drive all the discovery metadata views

  • A lingua franca for research


Requirements

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

… the answer

CERIFCommon European Research Information FormatCommon Exchange Research Information Format


Cerif a concise history

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

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

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

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

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

CERIF: Declared Syntax

  • Terms can be misleading

    • Senior researcher vs. Research associate

  • It’s the real meaning that matters

    • Definition

    • Description

    • Examples
