What is CERIF ?

Common European Research Information Format

(1) data model (data-centric focus)

(2) allows for a (metadata) representation of – research entities – their activities / interconnections (research)– their output (results)

(3) enables quality maintenance, archiving, access and interchange of research information

(4) supports knowledge transfer to researchers / research managers / research strategists / publication editors / media / brokers / the general public

What is Metadata ?

„Metadata is structured data which describes the characteristics of a resource.”

An Introduction to Metadata, by Chris Taylor, University of Queensland

“Metadata is sometimes defined literally as 'data about data,' but the term is normally understood to mean structured data about resources that can be used to help support a wide range of operations. These might include, for example, resource description and discovery, the management of information resources and their long-term preservation.” Metadata in a Nutshell, by Michael Day, UKOLN

What is data-centric ?

– Data / Metadata in the center – Data Maintenance, Curation, Preservation

and Quality a major interest – Enabling added-value Services based on

quality data

– Enabling requested views for various stakeholders based on quality data


10


What is a model ?

A model is a simplified view to describe a particular area of interest

It allows for a better communication between interested parties

It supports mutual understanding

It supports (re-)design decisions

It supports documentation

It can be exchanged, re-used, iterated, extended

What is going on ? JISC Report from April 2008“Metadata for digital libraries: state of the art and future directions”

by Richard Gartner http://www.jisc.ac.uk/media/documents/techwatch/tsw_0801pdf.pdf

Many available Schemas (DC, METS, MODS, …)

Each schema was singularly developed and not designed as an overal architecture to cover integrated object entities

JISC recommends therefore to overcome the problem by best practise guidelines and pragmatic application

Issues of duplicate information (overlap in sections of metadata) need rules and are currently being addressed by the library community in good practise guidelines


34




– Descriptive Metadata (intellectual contents)

– Administrative Metadata (technical metadata [file formats], rights management, provenance [info on creation, subsequent treatment, responsibility, …])

– Structural Metadata (internal structure of items: e.g.: page order, …)

• METS • DIDL• …


35




XML is of great importance to embed and make use of namespaces Combining Metadata standards, even a limited such as described

above, will always be messier than utilising a single standard that combines their taxonomic powers and resolves any potential clashes or duplications between them.

Integration by itself would of course be of little consequence if the standards themselves failed to address the metadata needs of the digital library community. In this respect, the provenance of each standard is of some importance. All have been constructed by authoritative standard setters within their communities.

Most of the mentioned standards have proved their ability to meet the requirements of major and highly complex digital collections.

CERIF 91

– published in a first release – recommended to Member States

• to harmonise databases on research projects• ease exchange of comparable information• guidelines for building research databases

– only dealt with research project records– demonstrated in the ERGO pilot project

• access to more than 80.000 project records• from more than 20 national information services

– demonstrated the feasability of exchange – identified the need for more detailed guidelines– confirmed the need to revise CERIF and extend it to other types of

research information, not only projects– revision activities started in 1997 co-ordinated by the EC – led to CERIF 2000


42


CERIF 2000

– a full CRIS data model with flexibility to accomodate many database structures

– a base framework for data exchange– multilingual subject indexing (Ortelius Thesaurus)– recommendations for controlled attribute values– reflection on user groups and requirements– types of research information – metadata environment as a uniform summary view– extensions to

• Organisations• Persons• Results: Products, Patent, Publication• Expertise• Equipment and Facilities


43


Major Current Activities

• UK: Research Councils specified to use CERIF as the format for IT processes and MM information

• UK: STFC (Corporate Data Repository)

• BE: Flanders – CERIF as Standard Interchange Format• DK: Danish Universities PURE -> CERIF

• EUROPEESF: CERIF for IS under discussionCORDIS, EC R&D Service: Asked for CERIF presentation EuroHORCS: Recommendation for CERIF; join as a euroCRIS member, from its taskgroup


44


Major Current Activities • Videolectures.net (Teaching Videos)• ICERIS (IS): Access to Information on Icelandic Research Projects & R&D

Results• AURIS-MM (AT): Provides access to Austrian University Research extended

with multimedia• SICRIS (SI): Access to University Research in Slovenia• HUNCRIS (HU): Access to R&D in Hungary• SRIS (UK): Scottish Research Information Systems, public research in

Scotland • CRIS-MER (EC): Research information on Migration and ethnic Relations

(planned)• STFC (UK): Corporate Data Repository• METIS (NL): currently used by Dutch Universities• Fdok (NO): University of Bergen, results• FRIDA (NO): Joint university CRIS• IWETO (BE): Integrating Flemish Research Information• BioDiversa ERANET (project)• IST World SSA (project)

CERIF TG Activity

Regular CERIF TG meetings and Discussions Tests and major bugfixes before Releases Strong Relation to ongoing implementation activities

(Geert van Grootel, EWI, Flanders; atira A/S, Aalborg, Denmark)

Exchange with Best Practice (Ales Bosniak, IZUM, Slovenia)

Collaborate with new TG Institutional Repositories (IR-CERIF)(Anna Clements, University of St. Andrews, UK)

Next Steps: Extension of Semantic Layer with Content Check Tools for Managing the Semantics Mappings of major Schemas (Standards) Check OAI Wrapping CERIF Ontology
