  1. MacKenzie Smith Associate Director for Technology MIT Libraries

  2. Agenda • Introduction • DSpace demo • Technical architecture • Organizational model • MIT case study • DSpace Federation • Q&A at the end of each presentation • General Q&A at the close

  3. DSPACEINTRODUCTION

  4. DSpace • Vision (1999) • A federated repository that makes available the collective intellectual resources of the world’s leading research institutions • Mission • Create a scalable digital archive that preserves and communicates the intellectual output of MIT’s faculty and researchers • Support adoption by and federation with other research institutions

  5. DSpace is… • An open source technology platform • A service model for open access and/or digital archiving • A platform to build an Institutional Repository • A (proposed) federation of digital repositories across multiple academic research institutions • A production service of the MIT Libraries to the local research community

  6. Institutional Repositories • Institution-based • Scholarly material in digital formats • Cumulative and perpetual • Open and interoperable

  7. The DSpace Repository • Institutional Repository for MIT faculty’s digital research materials • MIT Libraries - Hewlett Packard Research Labs collaborative development project • Open Source system • Federated system • Preservation archive

  8. DSpace Functions • Captures • Digital research material (any format) • Directly from creators (e.g. faculty) • Large-scale, stable, managed long-term storage • Describes • Descriptive, technical, rights metadata • Persistent identifiers • Distributes • Via WWW, with necessary access control • Preserves

  9. Preprints, articles Technical Reports Working Papers Conference Papers E-theses Datasets statistical, geospatial, matlab, etc. Images visual, scientific, etc. Audio files Video files Learning Objects Reformatted digital library collections Possible Content

  10. Why Libraries? • Expertise • Large-scale collection management • Assessment/collection policies • preservation • Metadata • Solid business practices • Commitment • Long time frames • Mission scope

  11. CHALLENGES

  12. Challenges • Faculty Acceptance • Valuing and trusting an institutional archive • Sustainability • institutional, financial • Digital Preservation

  13. Digital Preservation • Philosopy • Lots of digital material is already lost • Most digital material is at risk • Better to have it, do bit preservation, than to lose it completely • Need to capture as much information as possible to support functional preservation • Cost/benefit tradeoffs

  14. Digital Preservation • MIT’s commitment levels • Known/supported • TIFF, SGML/XML, AIFF, PDF • Known/unsupported • Microsoft Word, PowerPoint (common, proprietary) • Lotus 1-2-3, Visicalc, WordPerfect (less common) • Unknown/unsupported • One-of-a-kind software program

  15. Digital Preservation • Supported = migration and/or emulation • Migration for texts, images, audio, etc. • Emulation for software, multimedia? • Unsupported • Bit preservation at minimum • Format migration where possible • Commercial conversion services • Global Digital Format Registry

  16. DESIGN

  17. Information Model • Communities • Research units of the organization • Collections (in communities) • Distinct groupings of like items • Items (in collections) • Logical content objects • Receive persistent identifier • Bitstreams (in items) • Individual files • Receive preservation treatment

  18. Information Model • Versioning • Item “versions” can be • All instances of a work in different formats • E.g. the XML, PDF, and PostScript versions • All editions of a work over time • Official changes (e.g. addenda or new release) • Periodic snapshots (e.g. web sites) • Metadata lists all available versions of items

  19. Communities • Research units of the organization • Schools, Departments, Research Labs, Research Centers, Programs, etc. • Individuals • Community “home page” with logo, custom description, etc. • Or contract with library

  20. Communities • Local, distributed policy decisions • Who can contribute, access material • Submission workflow • Submitters, approvers, reviewers, editors • Collections definition, management • Local, distributed production work • Communities supply metadata, files • Partnership between library and communities

  21. Communities

  22. EDUCATIONAL TECHNOLOGY

  23. Problem • Lack of persistent repository for Learning Objects • Needed for reuse of • Entire courses • Useful “learning objects” • Prior efforts not institution-based • Merlot, HEAL, etc.

  24. Open Knowledge Initiative • Defines API for interoperation between • Course/Learning Management Systems • Open source (e.g. Coursework, Stellar) • Commercial (e.g. Blackboard, WebCT) • Digital Repositories • Open source (e.g. DSpace, FEDORA) • Commercial (e.g. TEAMS, Bulldog) • Collaborating with IMS Digital Repository working group

  25. OpenCourseWare “Make MIT course materials that are used in the teaching of almost all undergraduate and graduate subjects available on the Web, free of charge, to any user anywhere in the world.” “Course materials contained on the MIT OCW Web site may be used, copied, distributed, translated, and modified, but only for non-commercial educational purposes that are made freely available to other users under the same terms defined by the MIT OCW legal notice.”

  26. OpenCourseWare • Publication of all course content on the Web • Faculty-authored • 3rd party produced • Metadata based on IMS specifications • DSpace • Archive for entire course web site • Archive of significant content items or “learning assets” for rediscovery and reuse

  27. Metadata • SIMILE • Flexible metadata infrastructure • e.g. support for IMS/SCORM schema • HP/MIT Alliance-funded project • HP Labs • W3C’s Semantic Web activity • MIT Lab for Computer Science researcher (David Karger) Haystack project on personalized information management • MIT Libraries’ DSpace providing test-bed, real-world applications

  28. RESEARCH AGENDA

  29. Further R&D • Digital preservation • Datasets, multimedia, websites, programs • Economics and user requirements • Publishing • E-journal alternatives • Collaborative, iterative authoring tools • Rights management for academia
