What is CERIF ?

Common European Research Information Format


5


What is CERIF ?


– A Concept about Research Entities and their Relationships Specification (Conceptual Level)

– A Description of Research Entities and their Relationships Model (Logical Level)

– A Formalization of Research Entities and their Relationships

What is CERIF ?


(1) data model (data-centric)

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

(3) offers high flexibility with (semantic) relationships

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

(5) supports knowledge transfer to decision makers, for research evaluation, research managers, strategists, researchers, editors, the general public


7


What is a model ?

… is a simplified view to describe a particular area of interest

… allows for a better communication between parties (mutual understanding)

… supports (re-)design decisions

… supports workflow identification

… supports documentation

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

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

Support a Wide Range of Operations

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


41


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

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


43


What is going on ?



– 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• …


44


What is going on ?



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.
