1 DRIV(ER)ing Research Infrastructures Yannis Ioannidis University of Athens, Hellas 1st DRIVER Summit: Towards a Confederation of Digital Repositories, 16-17/1/2008, Göttingen

2 2 DRIVER Digital Repository Infrastructure Vision for European Research } } } } =? Research

3 3 Imperatives 1.Comprehensive, global access to any type of scientific information 2.Minimum time and resources effort to access and use this information 3.Easy search/navigation, handling, manipulation, and re-dissemination of information 4.Maximum visibility to and communication with the research community, research impact 5.Long-term access and preservation of research results

4 4 High-Level Objectives Develop an environment for integrating existing national, regional, or thematic repositories Create a production-quality European DR infrastructure Prepare the future expansion and upgrade of the DR infrastructure across Europe Identify and promote the use of a relevant set of standards Raise awareness among user communities

5 5 Challenges Create a European Repository Infrastructure Large number of providers and users Emphasis on content and services Hosting hardware and software Operational infrastructure, open for experimentations Multifaceted endeavor: technology, organization Organisation Data Software

6 6 Universal DRs Past-Present-Future National, Regional, and Thematic DRs Trans-National DRs (DRIVER) Pan-European and Inter-Thematic DRs

7 7 Repository Systems efforts Individual institution site Information Space Index Search Index UI … Centralized System High installation and maintenance cost for hardware and software Poor & limited scalability Reuse by data and service duplication! Functionality resources Content resources OAI-PMH

8 8 Repository Systems efforts Multiple institution sites Repeated efforts High installation and maintenance cost for hardware and software Poor & limited scalability Reuse by data and service duplication! Disconnected repositories ………………………………

Repeated efforts High installation and maintenance cost for hardware and software Poor & limited scalability Reuse by data and service duplication! Disconnected repositories Sometimes desired policy Often undesirable

11 11 DRIVER Infrastructure Vision Moving from building individual repositories or repository clusters, one at a time, repeating things again and again, to building a generating engine, a warehouse, an INFRASTRUCTURE, facilitating the above by offering appropriate generic, reusable services

12 12 DRIVER Infrastructure Vision Build and maintain a sustainable European environment where content and functionality resources can be openly shared and integrated for use by any application or community Sustainability - Maintainability - Scalability - Reusability

13 13 DRIVER Infrastructure Aggregator Index Search Index UI … Aggregator UI Search Index Store OAI-PMH Institution Site … OAI-PMH Institution Site OAI-PMH Institution Site … Content Resources Information Manager AuthnAuthz Enabling Services Content/Data Services Functionality Services

14 14 Fully flexible and dynamic –Repositories –Users –Communities –… –Services Fully distributed System –Services are implemented as Web Services –Service Oriented Architecture (SOA) Advantages –Scalability both on the data provided or the usage/load –Extensibility of functionalities is easily accomplished Technological features System Resources

15 15 Enabling Services Infrastructure management and service/resource gluing : handles all the nitty-gritty generic tasks (like an operating system) –Knowledge of all DRIVER Resources –Monitoring and coordination of Service interactions –Provides Authorization & Authentication mechanisms Information Manager AuthnAuthz

16 16 Content/Data Services Information Space Management –Harvesting from external repositories –Aggregating: cleaning & enriching –Storage, indexing –Virtualization of content: collections –OAI-Publishing of harvested data Aggregator Index Aggregator Index Store CollectionOAI-Publisher

17 17 Functionality Services User-content based services –User Interfaces –Information (Content) Search & Browse Personalized services –User and Communities –User Profiling –User recommendations & alerts Search UI Search Profiling Communities Alerts/Recommendations

20 20 DRIVER European Information Space Enabling Layer Data Layer Functionality Layer Repositories Services for the creation, maintenance, and access to the European Information Space

21 21 Data sharing & Service reuse Belgium scenario –Use European DRIVER infra –Have a storage/Index for themselves –Provide their (Belgian) data to Europe E-theses scenario –Include European theses documents in overall infra –Make these visible through virtual mechanisms (collections) for specialized searches India Scenario –Deploy DRIVER infrastructure for all their repositories

22 22 DRIVER infrastructure: the benefits Enabling Layer Data Layer Functionality Layer Repositories DRIVER Infrastructure DLS (Belgium) DLS (India?)

23 23 Current DRIVER content > 200,000 documents

24 24 Current DRIVER deployment

25 25 Current state of production First TEST-BED released (v1.0) Enabling Layer: Services deployed on DRIVER sites across Europe Data Layer: now aggregating 70 Repositories from 6 Countries (FR,BE,NL,DE,UK, IT) Functionality Layer: delivering Search User Interface with special functionalities: collections, recommendations, communities One running DIS: DRIVER European Information Space counting 51 reps, for Open Access docs

26 26 Content Resources Focus on Institutional Repositories –Rapid progress over the last years –Inherent sustainability (e.g. libraries) –Adequate technical homogeneity (OAI-PMH) Textual data Selection of IRs based on –Maturity –Policies –Technologies used

27 27 Content Sources Initially 51 institutional repositories –15 from the Netherlands (coordinated by DARE) –20 from the UK (coordinated by SHERPA) –14 from Germany (adhere to the German DINI-standard) –1 from France (CNRS) –1 from Belgium (UGent) Later raised to 70+ and growing More repositories to be identified and included Joint policies and objectives Broad and multiple user groups Metadata, technical, and organisational standards

28 28 Future issues Towards release v1.1 Addition of new DISs sharing the European Information Space –Belgium –Ireland –Electronic Theses and Dissertations –India? –more to come… New content types, and compound documents/scientific objects New functionality services

29 29 Simple Search Scenario UI Index IS RS Search

30 30 DRIVER portal

31 31 DRIVER Activities Content: Organisation and Provision Content: Organisation and Provision Infrastructure Middleware Development/ Implementation Infrastructure Middleware Development/ Implementation Focussed Studies Raising Awareness / Outreach Programme

32 32 DRIVER Funding DRIVER project: 18 months (6/06-11/07) –An organization and a testbed system DRIVER2 project: 24 months (12/07-11/09) –A confederation and a production system –Research on next-generation issues DRIVERn project Driver Confederation members Member states

33 33 Summary DRIVER drives Europe towards full unification of its scientific information
