BELIEF-EELA e-Infrastructures Conference - Rio De Janeiro, Brazil, June 25-28, 2007

• IST programme FP6

• Test bed infrastructure

• 18 months (June 2006 – November 2007)

• Two public releases:– End of July

– End of Nov

• Project website– www.driver-repository.eu

Partners• Univ. of Athens (Greece) – administrative coordinator• Univ. of Göttingen Library (Germany) – scientific coordinator • CNR-ISTI (Italy) – technical coordinator• SURF (the Netherlands)• Univ. of Nottingham – SHERPA (UK)• CNRS (France)• UKOLN (UK)• ICM (Poland)• Univ. of Ghent Library(Belgium)• Univ. of Bielefeld Library (Germany)

Objectives

• Develop a test-bed for integrating existing national or regional repositories

• Create a production-quality European DR infrastructure

• Identify and promote the use of a relevant set of standards

• Prepare the future expansion and upgrade of the DR infrastructure across Europe

• Raise awareness among user communities

computer-generated images, etc.

Primary Data Observational, experimental, demographic, census, patient

records etc.

Complex Objects, Living/Dynamic Documents

Software, Simulations

Images, Photographs

Open Access

Networking

• Focus on Institutional Repositories– Rapid progress over the last years– Inherent sustainability (e.g. libraries)– Adequate technical homogeneity (OAI-PMH)

• Selection of IRs based on– Maturity– Policies– Technologies used

Network of content providers– Germany (DINI)

• National Policies • Model for quality assurance

– France (CCSD) • Centralized Scheme • Model for centralized network

– The Netherlands (SURF) • National Federation/Aggregated Network • Model for Distributed Network

– United Kingdom (SHERPA) • National Federation • Model for advocacy

– Belgium (Ghent Lib) • Model for network construction

Infrastructure Technology• DRIVER envisions the notion of European Repository

Infrastructure enabling for– The construction of Repository Systems in an easy,

standard and sustainable way– Integrating content and functionality of the existing

Repository Systems by respecting their autonomy

• Provides a distributed environment for the construction, maintenance, and coexistence of Service-based Repository Systems

Technological features

• Repositories • Users • Communities• …• Services

– Scalability depending on the data provided or the usage– Extensibility of functionalities provided

• Services are implemented as Web Services

• Open source technology

Enabling Layer

• Infrastructure management– Resource/Service Registration (P2P-like)

– Discovery (by functionalities and capabilities) – Orchestration of Services: coordination of Service

interactions

– Authentication and Authorization of all resources

DR Testbed Service

Repository Inventory in Europe

• Results from ~120 institutions with DRs– General status on national level infrastructure– Coverage/visibility of academic output– Textual vs. other material – Open access (88%)– Repository technologies used– User services provided

Technical Standards• Analyzes current implementations of interoperability

standards in DR's. • Identifies limitations of the standards currently used, and

looks into the necessary future development of existing or new standards to resolve difficulties

• Describes other standards that are used (or being developed) in different environments

• Anticipates new challenges: – Guidelines for OAI-PMH implementations– Multiple interfaces to repositories – Challenge of relating entities from multiple domains– Content based-services

DRIVER outreach

• Produce advocacy materials

• Publish study results

• Presentations at Conferences

• Establish `European Repository Awareness Point’ (E-RAP) as community resource– www.driver-support.eu

• Up-coming public releases
