Define: Digital Library “ Digital libraries are organizations that provide the resources, including specialized staff, to select, structure, offer intellectual access to, interpret, distribute, preserve the integrity of, and ensure the persistence over time of collections of digital works so that they are readily and economically available for use by a defined community or set of communities.” Digital Library Federation Annual Report ,(1998-1999) 1.

    http://www.flickr.com/photos/biwook/145765624/sizes/m/
  • 60. Why is metadata UNimportant?
    • Seven insurmountable obstacles to reliable metadata:
      • People lie
      • People are lazy
      • People are stupid
      • Mission Impossible: know thyself
      • Schemas aren't neutral
      • Metrics influence results
      • There's more than one way to describe something
    Cory Doctorow - Metacrap http:// www.well.com/~doctorow/metacrap.htm
  • 61. Metadata Types
    • Descriptive
      • What is it?
      • Where is it?
      • What is it about?
    • Structural
      • How many files are there?
      • Which file is on page one?
    • Administrative
      • What do I need to know to manage it?
      • Who can access it?
      • What needs to be preserved?
    • Technical
      • What is the resolution of the image?
      • What compression format was used?

  • 65. Deciding on a scheme It is very important to decide what the material is, what needs to be described, who it is intended for, how it will be retrieved, and how it will be processed and used before deciding on a scheme for its description. - Dr. Peter Noerr Digital Library Toolkit – Sun Microsystems
  • 66. Metadata Content Standards
    • In other words, rules for how we describe things
    • May include punctuation, format, etc.
    http://www.flickr.com/photo_zoom.gne?id=1252545857&size=m
  • 67. Metadata Content Standards
    • Rules and guidelines for metadata content
    • Choice usually driven by type of content being described
      • Anglo American Cataloging Rules (AACR)
      • Describing Archives: A Content Standard (DACS)
      • Cataloging Cultural Objects (CCO)
  • 68. Relationships: content standard + element set

  • 70. What data structure(s) do staff use to create metadata?
  • 71.  
  • 72. Metadata du Jour
    • Description vs. discovery
      • Full description is important for collection inventory and management - less so for discovery
    • Basic and shallow or deep and sophisticated?
      • Basic discovery metadata supports broad, cross-domain searching that can lead users to more complete search mechanisms and descriptions
    • Context
      • Will your descriptions be adequate outside your institution’s environment?
  • 73. Interoperability
    • Allows different systems to make use of the same data
    • Usually achieved by following standards
    • In general, an increase in specialization results in a decrease in interoperability
    • Important feature of metadata in today’s world
  • 74. Interoperability
    • National Initiative for a Networked Cultural Heritage (NINCH) Guide to Good Practice first two of its six core principles:
        • Optimize interoperability
        • Enable broadest use
    • IMLS Leadership Grant
      • “ Project design should demonstrate the use of existing standards and best practices for digital material where applicable, and products should be interoperable with digital content.”
  • 75. Shareable Metadata
    • Six C’s:
      • Content
      • Consistency
      • Coherence
      • Context
      • Communication
      • Conformance
  • 76. Information R/evolution http:// youtube.com/watch?v =-4CV05HyAbM
  • 77. Technology
  • 78. Technical Considerations
    • Storage of metadata and digital files
    • Database software

      • Includes link from metadata to resource
    • Hardware
      • Servers – storage and access
      • Bandwidth
    • User interface
      • Usability testing
