Knowledge Exchange is an international co-operative effort

that supports the use and development of e-infrastructures

for higher education and research.

Partners are:

Denmark’s Electronic Research Library (DEFF)

German Research Foundation (DFG)

Joint Information Systems Committee (JISC) in UK

SURF foundation in the Netherlands�

+Motivation: Enable broad collaboration in the

information management of research publications

Current Research Information Systems

a label for research management systems of various

types, dealing with many aspects of research activities

contain metadata on research publications

Open Access Repositories

a label for for open research output archives aiming at

preservation and dissemination of publications etc.

contain metadata on research publications

They share the challenge of achieving full metadata

coverage for the publications within their scope

CRIS

OAR

INTER

OPERA

If CRIS and OAR easily could exchange metadata about

publications, they could support each other

But CRIS and OAR have grown out of different

communities and have developed rather different

approaches to publication metadata

If a university has a CRIS and an OAR, generally a

publication must be registered twice to comply with

both systems’ requirements

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

CRIS use a variety of formats – some use CERIF

(or variants thereof) and some use various local or

national formats

In many disciplines, publications are of global interest

and are often results of international collaboration

They are often of interest to more than one CRIS

CRIS with different formats would benefit from an easy

and precise mechanism to exchange publication

metadata

information management of research publications

+Aim and purpose

To increase the metadata interoperability

between CRIS and OAR systems

and thus also

between CRIS and CRIS with different formats

between OAR and OAR with different formats

by defining and proposing

1.a metadata exchange format for publications

2.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

CRIS formats are characterized by their

broader view on research information depicting research

results as well as the actors and various environmental

factors in their own right

(often) high level of detail and specificity in describing the

various entities (very granular and precise)

ability to handle the dynamics of time – as everything else

but research publications changes over time as well as

their interrelations

+Bridging publications metadata

OAR (DC) formats are characterized by their

Narrow view on depicting research results – generally

publications

(mostly) low level of detail and specificity in describing the

various aspects (less granular)

absence of need to handle the dynamics of time – as they

deal with research publications tied to a specific point in

time

CRIS

OPERA

+Bridging publications metadata

Implode the relational/network nature of the

CRIS formats to a single structure – adequate for

describing publications

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

Looking at formats in actual use at KE partners

Chart entities and granularities, similarities, differences

CRIS

OAR

INTER

OPERA

+ Project approach

2. Define entities/elements/attributes to be exchanged Respecting differences in granularity

So that metadata may be exported without loss of information

So that the format may be used by very granular

environments as well as less granular

3. Define/propose common exchange vocabulary

For the identified key concepts/entities

4. Define/propose common exchange syntax

Handle differences in granularity

+Vocabularies - Versions

Version

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”.

Important! Different versions should be self contained and constitute

individual records. This mirrors best-practices for repositories but not

always the case for CRIS.

Terms:

Draft i.e. working paper

Submitted i.e. pre print

Accepted i.e. post print

Published i.e. publisher edition

Updated i.e. reprint
