Knowledge Exchange is an international co-operative effort that supports the use and development of e-infrastructures for higher education and research.

Partners are:n Denmark’s Electronic Research Library (DEFF)n German Research Foundation (DFG)n Joint Information Systems Committee (JISC) in UKn SURF foundation in the Netherlands.

+Motivation: Enable broad collaboration in the information management of research publications

nCurrent Research Information Systemsn a label for research management systems of various

types, dealing with many aspects of research activitiesn contain metadata on research publications

nOpen Access Repositoriesn a label for for open research output archives aiming at

preservation and dissemination of publications etc.n contain metadata on research publications

n They share the challenge of achieving full metadata coverage for the publications within their scope

n If CRIS and OAR easily could exchange metadata about publications, they could support each other

n But CRIS and OAR have grown out of different communities and have developed rather different approaches to publication metadata

n If a university has a CRIS and an OAR, generally a publication must be registered twice to comply with both systems’ requirements

n Both CRIS and OAR strive to be complete in their coverage of publications – both would benefit from collaboration – not to mention the authors/researchers.

Motivation: Enable broad collaboration in the information management of research publications

n CRIS use a variety of formats – some use CERIF (or variants thereof) and some use various local or national formats

n In many disciplines, publications are of global interest and are often results of international collaboration è They are often of interest to more than one CRIS

n CRISwith different formats would benefit from an easy and precise mechanism to exchange publication metadata

Motivation: Enable broad collaboration in the information management of research publications

+Aim and purpose

n To increase the metadata interoperability n between CRIS and OAR systems

n and thus alson between CRIS and CRISwith different formatsn between OAR and OAR with different formats

n by defining and proposing 1.a metadata exchange format for publications2.a set of common vocabularies for key elements

We (simply) build a bridge that will enable these islands to communicate - without changing their language and life style.

That will allow them to exchange publication metadata without studying and understanding the particularities of the other part.

+Bridging publications metadata

n CRIS formats are characterized by their n broader view on research information depicting research

results as well as the actors and various environmental factors in their own right

n (often) high level of detail and specificity in describing the various entities (very granular and precise)

n ability to handle the dynamics of time – as everything else but research publications changes over time as well as their interrelations

CRISOAR

+Bridging publications metadata

n OAR (DC) formats are characterized by their n Narrow view on depicting research results – generally

publications

n (mostly) low level of detail and specificity in describing the various aspects (less granular)

n absence of need to handle the dynamics of time – as they deal with research publications tied to a specific point in time

+Bridging publications metadata

è Implode the relational/network nature of the CRIS formats to a single structure – adequate for describing publications

è Design the field/element hierarchy so that highly granular as well less granular metadata may be represented – without loss of information

+ Project approach

1. Analyze metadata practices of CRIS and OAR n Looking at formats in actual use at KE partnersn Chart entities and granularities, similarities, differences

CRISOAR

INTEROPERA

+ Project approach

2. Define entities/elements/attributes to be exchangedn Respecting differences in granularityn So that metadata may be exported without loss of informationn So that the format may be used by very granular

environments as well as less granular

3. Define/propose common exchange vocabularyn For the identified key concepts/entities

4. Define/propose common exchange syntaxn Handle differences in granularity

n Description: This element and vocabulary is expressing the version of the document i.e. draft or published version of the document. The terms are based on the VERSIONS toolkit excluding the term “updated”.

n Important! Different versions should be self contained and constitute individual records. This mirrors best-practices for repositories but not always the case for CRIS.
