  • 1. DSpace: Or How an Electronic Resource Management Enterprise at MIT Solved all the Problems of the Digital World. Butch Lazorchak CRADLE July 14, 2003
  • 2. DSpace: What is it, exactly?
    • A Digital “Depository”
    • A Digital “Repository”
    • An Open Source Software Platform
    • A Groundbreaking Digital Library System
    • A Specialized Type of Digital Asset Management or Content Management System
  • 3. Commercial Digital Asset Management Systems (DAMS)
    • Documentum
    • MediaBin/Interwoven
    • North Plains Systems-Telescope product
    • Artesia
    • Oracle Intermedia
    • Lots of others…
  • 4. Welcome to Acronymland! OCW-Open Courseware DSpace-“digital space,” “design space,” “dissemination space” or some combination of all or none of those Invent@MIT, the HP-MIT Alliance (a joint venture) MIT Libraries operate DSpace at MIT MITCET-MIT Council on Educational Technology
  • 5.
    • MIT libraries has a particular mission for the MIT instantiation:
    • to provide stable long-term storage to house the digital products of MIT faculty and researchers;
    • to provide long-term preservation for digital materials in a variety of formats, including text, audio, video, images, datasets and more;
    • and to enable remote access to those materials through one coherent interface.
  • 6.
    • DSpace: What’s it look like?
  • 7. Why is Dspace all the hype?
    • Complete, easy-to-read documentation, understandable by non-technologists
    • Standards-based (Dublin Core, XML, established/robust open source software), allowing it to easily co-exist with established/co-developing systems
    • An implementation design plan that is easy to follow (even if earlier versions of the software were buggy)
    • The design originated in the library system (as opposed to the CS department), emphasizing the importance of library considerations (and bolstering the techno-confidence of librarians everywhere)
    • Sexiness of the name (relatively speaking), the MIT connection, the dollar power of HP, and first to market (of the research solutions?)
  • 8. They’ve figured it all out:
    • Complete digital asset management system
    • Open source solution
    • Support for long-term preservation
    • All data types supported, including ones that haven’t even been invented yet
    • Protects and guarantees the authenticity of the digital materials over time
    • Bundles rights management information with each digital artifact
    • Supports interoperability
  • 9. DSpace: the elegant integration of user-centered and system-centered capabilities
    • Users
      • Contributors
      • Researchers
      • End Users
    • Content and Services
      • Content Types
      • Submission Process
    • Technology
  • 10. Who are These “Users”
      • Contributors
        • MIT Faculty exclusively (at the moment)
      • Researchers
        • Federators (Columbia, Cornell, Ohio State, U’s of Rochester, Washington, Toronto)
      • End Users
        • Everybody in the whole, wide world
  • 11. Content and Services
    • Content Types-
      • Any kind of digital content imaginable
      • Long-term preservation support for the actual bits is guaranteed
      • Software types are maintained and supported through the use of a bitstream manager
    • Submission Process
      • A Sharium! Decentralized submission process
      • Ingest process which incorporates human-edited and machine-annotated processes
      • Provenance and authentication through the use of checksums
      • Handle System persistent identifiers
      • Rights management utilizing Creative Commons licenses
  • 12. Technology
    • Open Source-get it at SourceForge
    • Scalable-from your laptop to the mountaintop (as long as it’s a Unix-type environment)
    • Dublin Core DC-LIB metadata schema, but SIMILE (Semantic Interoperability of Metadata and Information in unLike Environments) is on the way ( http://web.mit.edu/dspace-dev/www/simile/ )
    • Interoperability (Semantic Web, OAI); Intelligent Agents; Complex metadata schemas
  • 13. DSpace: Good
    • A Complete Scalable System
      • Providing for Long-term
        • ACCESS
    • Outside of propriety constraints
    • And with a vision of how digital information can serve us in the future
  • 14.
    • It is important to note that the DSpace system operates entirely within the open-source software framework, freeing it from the encumbrances of proprietary software. The prerequisite software for DSpace includes a UNIX-like operating system (HP/UX, Linux, Solaris or Macintosh OS X), though the application itself is written in Java. The tested versions of the following software are also required; Java 1.3 or later; Tomcat 4.0; Apache 1.3; Ant 1.4; and PostgreSQL 7.2.3 [i] . DSpace also utilizes Lucene, a Java freeware search engine, and the user interface Resin, a Java Servlet engine which also provides support for Java Server Pages. The user interface is entirely web-based at this time, which provides for very simple interaction with the system.
    • In terms of hardware, DSpace has no specific requirements (the software is designed to run on everything from a laptop to an expensive server), but they do include general recommendations for a system designed for a research university: a reasonably good server (e.g. Sun Fire 280R Server, two 900Mhz UltraSPARC-III Cu processors, 8MB E-cache, 2GB memory, two 36GB 10,000rpm HH internal FCAL disk drives, DVD) and a decent amount of disk storage (e.g. 436-GB, or 12 x 26.4 Gbyte 10K RPM disks, Sun StorEdge A1000 rackmountable w/1 HW RAID controller, 24MB std cache). With tape backups and accessories the system above should cost around $30,000. [ii]
