DRIVER Infrastructure Vision: Building a Sustainable European Environment for Research Repositories

This project aims to develop a cohesive European repository infrastructure for scientific research, enabling comprehensive and global access to data with minimal effort. The initiative focuses on creating an environment for seamless integration of existing repositories, fostering communication within the research community, and ensuring long-term preservation of research outcomes. High-level objectives include the creation of a production-quality European repository infrastructure and the promotion of relevant standards. By addressing challenges in organization, data management, and software development, the project seeks to enhance the efficiency and scalability of repository systems.

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

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

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

  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. 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

  14. Technological features • 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 System Resources

  15. Enabling Services Information Manager Manager AuthnAuthz • Infrastructure managementandservice/resourcegluing: 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

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

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

  23. Current DRIVER content > 200,000 documents

  24. Current DRIVER deployment

  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 250.000 Open Access docs

  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. 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. 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
