  • 1. MIDESS M anagement of I mages in a D istributed E nvironment using S hared S ervices. Dr Stephen Charles MIDESS Project Manager
  • 2. MIDESS Project
    • Looking at the issues involved in using and sharing multimedia material (not just images!) in digital repositories.
    • Areas of interest.
      • Interoperability between different repositories (DSpace, Fedora, DigiTool)
      • Metadata schemas/metadata for multimedia
      • Integration with Enterprise Architecture
      • Long term preservation of digital material
  • 3. MIDESS Project
    • MIDESS partners are:
    • University of Birmingham
    • University of Leeds
    • London School of Economics (LSE)
    • University College London (no repository installed as part of MIDESS project – examined copyright issues around multimedia).
    • Sponsored by the JISC and by CURL
  • 4. Digital Repository Software evaluated in depth as part of the MIDESS project
    • Dspace (open source)
    • Fedora (open source)
    • Greenstone (open source)
    • Encompass/Curator (commercial)
    • DigiTool (commercial)
    • Symposia (commercial)
    • Detailed evaluation of all products on MIDESS website (Work Package 3)
  • 5. MIDESS work-packages
    • User needs analysis
    • Functional and technical evaluation of digital repository software packages
    • Implementation of digital repository.
    • Metadata requirements analysis
    • Digital preservation requirements analysis
    • Enterprise integration
    • Copyright and IPR review
    • Resource discovery and shared services review
    • Metadata Harvesting
    • Evaluation and dissemination
  • 6. Enterprise Integration: Streamed Server and SAN
    • MIDESS video and sound material stored in a MIDESS repository is streamed from a Helix streamed server (Example in demonstration)
    • Integration with Storage Area Network (SAN). Flexibility in speed of access dependent upon where files are stored on the SAN.
  • 7. Digital Collections at the MIDESS Partners
    • These include:
    • Medical images - slides/x-rays, etc.(Birmingham/Leeds)
    • Dialect recordings (Leeds School of English)
    • Fine art images (Birmingham/Leeds)
    • Digitised pages from manuscripts and other Library special collections (Leeds/Birmingham/LSE)
    • Images of textiles (Leeds Textile Museum)
    • Images and video from Media Services (LSE/Birmingham/Leeds/)
    • Recordings of music (Birmingham/Leeds)
    • Training/E-learning material/video of lectures etc (LSE/Birmingham/Leeds/)
  • 8. Manuscripts (Birmingham/ Leeds,) Coins (Birmingham,Leeds) Medical images (Leeds, Birmingham) Media Services Images (LSE , Leeds,, Birmingham)
  • 9. Sharing Data across Repositories
    • What are the best techniques?
    • OAI-PMH (Metadata Harvesting)? But doesn’t harvest the bitstream (image, video, sound etc).
    • Export of files eg METS?
    • Export from underlying database (Oracle, SQL Server MySQL etc)?
  • 10. Next Step - Integration of Digital Library Systems
    • The ultimate goal is to integrate the following seamlessly:
    • Digital repositories (Scholarly repository, Multimedia repository, e-learning repository etc)
    • VLE’s
    • Portal Systems
    • Library Management Systems
    • Electronic Journals etc.
  • 11. Digital Repositories requirements/wish list
    • Improved Digital Preservation support - system addition of technical/preservation metadata and updating of formats.
    • Flexible metadata standards (not just Dublin Core/qualified Dublin Core). May include: VRA Core/LOM/bespoke metadata schemas (schemas should be easy to create) etc.
    • Highly CUSTOMISABLE digital repository systems which can be EASILY tailored (ideally without resorting to Java/complex programming etc).
  • 12. Digital Repositories requirements/wish list
    • Flexibility in authentication using techniques such as IP address restrictions, LDAP (Windows active directory), Shibboleth, Passwords etc.
    • Ability to handle content packaging standards for e-learning (eg IMS, SCORM etc). Library based repositories are poor at this.
    • Ability to easily interface with other systems eg: Library Systems, Portals, Virtual Learning Environment’s etc).
  • 13. Multimedia Demonstration Repositories
    • DSpace Birmingham
    • Fedora LSE
    • Leeds
    • Zoomify (protects high resolution images)
  • 14. Summary
    • Setting up digital repositories requires a lot of work!
    • No such thing (yet) as the ideal Digital Repository software, all have strengths and weaknesses.
    • Important to understand user requirements before you start.
    • Its early days for digital repositories – numerous improvements on the way.
