    • The National Library of Wales
      • Nature of NLW
      • Collecting
        • Variety of data types and formats
      • Preserving
        • Obsolescence
        • Lack of context information
        • Persistent identifiers
        • Integration
      • Access
        • Open collections
    • Why we choose Fedora
      • Comparison with D-Space
      • Fundamental issues
        • Suitability for wide range of data types
        • Suitability for distribution of data types
        • Support for collection structures
        • Scalability
        • `Future-proof’ architecture
    • The Pilot
      • Understand the Fedora System
      • Experiment with different data types
      • Allow access to Digital Assets
      • Investigate workflows for moving digital material into the repository
    • Examples
      • Ingested Digitised Images
      • E-Thesis
      • Ingested web pages
      • Born Digital Object
      • Basic authentication and rights management
    • E-Thesis
      • Abstract
      • Word Document Thesis
        • Original, PDF, Text, HTML and Tiff page images
      • Video Composition
        • Original, DivX and Web Viewer
    • Web Pages
      • Complex Digital Objects
        • Arrive in a Compressed File
      • Dissemination 1 Uncompress tar and serve
        • Simple
        • Difficult to migrate formats
      • Dissemination 2 Extracted and ingested into Fedora
        • More complicated
        • Can do format migration without breaking links
        • HTML converted to XHTML
        • Meta data can be assigned to each page, image or movie.
    • Digitised Images
      • Problems:
        • Obsolete Formats
        • Loss of context information
        • Persistent identifiers and URLs
        • Integration
        • Access
    • Digital Images – Obsolete Formats
      • What if we move from jpeg to jpeg2000
        • Website would have to be updated
        • All links would break:
          • http://cairsweb.llgc.org.uk/images/mst/mst00001.jpg
        • Special Viewer?
      • Fedora’s Solution
        • Find all images
        • Add a disseminator to convert jpg files to jpeg2000
        • Links not file specific:
          • http://teilo:9080/llgc/getImage/getMedium?PID=llgctest1:189
        • Record conversion in meta data
        • History automatically saved
    • Digital Images – Context information
      • Fedora’s Solution
        • Mets Document in object as Data Stream
        • Version history so changes saved
        • Can store any type of Meta data:

          • PREMIS Preservation Meta data
        • Could even store the intro page located on the Digital Mirror
    • Digital Images – Persistent Identifiers

        • Data Type independent URLs
          • http://teilo:9080/llgc/getImage/getMedium?PID=llgctest1:189
        • Fedora PID constant even through upgrades
        • Can add any Identifiers using Fedora relationships
        • URLs link to Servlets for redirection
          • GetMedium Servlet1
            • Find pid llgctest1:189
            • Get Mid sized image Data Stream
            • Convert to JPEG2000
            • Return Image
