Building Repository Networks with DRIVER

Wolfram Horstmann

Universität Bielefeld

DRIVER motivation

Scholarly communication changes towards distributed provision of text, data and services

Repositories are thought as a saviour in this development building such a distributed system

An infrastructure supporting distributed repositories and services is needed

(and reactions)

(needs explanation)

DRIVER Objectives

Organisational structure for repositoriese.g. the „Confederation“

Improving quality and standards in local rep.e.g. validation procedures

Building a distributed runtime systeme.g. service and data sharing

Target GroupsRepository Managers

Service Providers

Information System Executives

Build on knowledge from past & current IR projects (EU)26 actively involved contributors (experts and repository managers) from 8 countries.Practical answers on how to:

Improve full-text access Standardize metadata qualityCreate a reliable infrastructure for permanent identification, resolution, traceability and storageResolve semantic and classification issues

Options for Networking of Repositories

Using the DRIVER D-NET production systemForming an open & reusable information space

Quality standards of repositories in the focus

Building a service based on DRIVER D-NETUser interface for a specific section of DRIVER

Becoming national aggregator / country correspondent

Run your own services on your own machines

Having an own D-NET installationMaintain your own hardware and software

Develop your own infrastructure service

Cooperation with CAS

Technical cooperation with CAS: Basics

Exploring own infrastructure most powerful / demanding

Own D-NET infrastructure for CAS IR-Grid

Own deployment, individual service development

Bielefeld helps with installation of CAS D-NET

Win/Win-Situation for CAS and D-NETCAS receives exclusive test-version D-NET v1.1 Not ready to install but therefore highest available version Dedicated personell effort in Bielefeld for CAS

CAS tests aptitude of D-NET for their purposes No obligation from DRIVER to take it

D-NET receives feedback for D-NET v1.2 What has to be improved or extended?

Technical cooperation with CAS: Events

Start in Summer 2009 with Mr. ZhuProvision of machines in China

Remote installation of D-NET by Imialek (Bielefeld)

First tests and feedback by Mr. Zhu

Ongoing communication between Imialek and Mr. Zhu

Visit of Ma Jianxia in November 2009Double Checking CAS repository standards

Study of issues and challenges with D-NET v1.1

Registration of Chinese repositories in DRIVER D-NET

Aggregating 2 Chinese repositories on CAS D-NET

Will continue with limited scope: eMail / Visits

Technical cooperation with CAS: Results

„Much richer than initially expected“DRIVER helping CAS with repository standards Important for being „networkable“, also internationally

CAS helping DRIVER identifying challenges with v1.1 Documentation, installation routines, interface localization

Communication between techn. partners established Bielefeld (Germany), Athens (Greece), Pisa (Italy)

CAS should now have a „flavour“ of D-NET How to build a powerful and flexible IR-infrastructureColloboration in open-source service development ?CAS as Chinese „Country Correspondent“ for DRIVER?Decision still open – but experience is promising

To be continued …
