TRANSCRIPT
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
Some Results: Guidelines
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
Some Results: Service-Oriented-Arch.

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
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 …
