  • Transcript

    • 1. Making a taxonomy work for the organisation Liddy Nevile Sunrise Research Laboratory/La Trobe University
    • 2. Making a functional taxonomy
      • The role of a taxonomy is not limited to discovery within the realm of the creator of the digital library.
      • What is necessary for a good taxonomy to work inside and outside the organisation, for the organisation?
    • 3.
      • How interoperable are the organisation’s resources?
      • How do outsiders access and contribute to the organisation’s knowledge base?
      • Does the individual user get access to what they need to use the resource?
      Three interoperability problems
    • 4.
      • Opening the silos across the organisation
      • Integrating external and internal resources for external and internal use
      • Considering the individual so that everyone gets access to the resources
      Three dimensions to the problem
    • 5. Three case studies
      • Victorian government ‘silos’
      • Quinkan Rock Art
      • AccessforAll considerations - TILE
    • 6. Interoperability
      • Structure
      • Syntax
      • Semantics
      • (system conformance)
    • 7. 1. Working across the silos
      • Making Inter-operability Visible
        • Visualising Interoperability: ARH, Aggregation, Rationalisation and Harmonisation
        • With Michael Currie, Meigan Geileskey, Richard Woodman
      • Project of Victorian Department of Premier & Cabinet
      • http://www.bncf.net/dc2002/program/ft/paper21.pdf
    • 8. 1. Working across the silos
      • 3 government departments all using the same AGLS schema
      • Differences in purpose - one makes brochure-ware, one records critical info, one does broad-based research, ….
      • All have document m’ment systems
      • All docs must be discoverable
    • 9. Process
      • Aggregate -
        • List all elements and values currently used - is there a significant difference?
    • 10.  
    • 11. Process
      • Aggregate
      • Harmonise
        • Look at the list of elements and decide which have material differences
      • **Remembering that each agency values all its metadata content
    • 12. Harmonise trivial differences
      • Mis-use of available elements, qualifiers etc
      • Different expression of the same type of information
      • Different granularity
      • Different element name for the same information, …
      • -> need to rationalise
    • 13.
      • Element names
        • Inconsistent case eg. DC.Title/TITLE/title EDNA.Userlevel/UserLevel
        • Non-standard names eg. DC.Keywords
        • Non-standard qualifiers eg. DC.Description.Abstract
        • Non-standard abbreviations eg. DC.Lang
      • Fields
        • Standard and non-standard element names
          • eg. 'description' and DC.Description and Custodian
      Rationalise
    • 14.
      • Values
      • (Despite DCMES recommendations …)
        • DC.Identifier:
          • other id numbers without qualifiers.
        • DC.Date:
          • also used yyyy, yyyy/m/d, yyyy-dd-mm
        • DC.Format:
          • Non-standard terms eg. VHS (PAL)
          • Incorrect case eg. text/HTML
      Rationalise
    • 15.
      • DC.Language: also used en, en-au, en-AU
      • Qualifiers embedded in values:
        • DC.Publisher CONTENT="corporateName=State..."
      • Non-standard proper names
        • DPC for Department of Premier and Cabinet
      • ->Generally inconsistent use of capitalisation and punctuation
      Rationalise
    • 16. Discoveries
      • Main problems were to do with incompatibility of syntax and semantics although both were well described in documentation and looked very simple.
    • 17. Outcomes
      • Minimal interference
      • Visualisation of differences/incompatibility
      • Support for local specification and global interoperability
      • Base for a single system to satisfy many purposes using ARH approach
    • 18. 2. Repatriation of Quinkan Culture
      • with Eric Wainwright (Team Leader), Sophie Lissonnet (metadata) and others
      • An ARC funded LINK Project
      • Full report - http://eprints.jcu.edu.au/1135/
      • Int. J. of Metadata, Semantics and Ontologies (IJMSO)
ISSN Vol 1 No 3. (Online): 1744-263X  -  ISSN (Print): 1744-2621
    • 19. Quinkan Country Images from the Laura Booklet published by the Ang-gnarra Corporation
    • 20. Quinkan Culture
      • People were here 36,000 years ago
      • The community has been ravaged in the last 200 years and so has the culture
      • 60 people remain
      • 290 km from the nearest city
      • with 100,000 Rock Art paintings in excellent condition.
    • 21. Repatriation of resources
      • The problem - seamless import and export of descriptions to offer a single portal
      • People moving out of country stay connected and those in country can learn from those out of country
      • Multiple voices for multiple audiences
    • 22. Dublin Core - qualified
      • A standard form of description with rule-based extensions
        • Locally specific - globally interoperable
      • Standard mappings from other standards
      • Enabling functions on the classifications for better discovery
        • Annotations
        • Semantic Web applications
    • 23. Semantic Web applications Tommy George inspecting red rock ochre. "A lot of paintings are made in red."
    • 24. Annotation Services
      • W3C annotation server (Annotea)
      • Uses W3C standards and technologies
      • Uses RDF metadata framework
      • User accessible
      • Create, store, edit and delete annotations

    • 26. 3. Access For All
      • By law in Australia, all public resources to be available to all equally ie do not discriminate against those who cannot access text, or sounds, or visuals.
    • 27. How do we know what he needs?
    • 28. Accessibility (M’soft)
      • 60% working adults in the US - esp. many who are not self-identifying
      • ?% people using alternative devices, eg phones?
    • 29. Accessibility metadata
      • Even if resources are accessibility standards conformant, those that suit an individual user are:
        • not necessarily accessible to her
        • not discoverable if they are accessible
    • 30. Accessibility accommodations
      • By lowest common denominator?
        • W3C WAI standards
      • By presumed audience?
        • Guess work by site developer
      • By individual user?
