Observations of metadata creation
  • When entering metadata for a learning object
    observations show that
  • Phrases rather than single words are used
  • Repeated content is often used
  • Very few keywords are entered if any
  • The keywords used were either very specific or
    very generic, rarely a mixture of both
  • This creates a problem for searchers of
    information and limits the possibility of the
    learning object being found within a repository

Assumptions
  • Deposit of existing materials
  • Just add metadata
  • Documentation describes the learning object
  • More keywords are better
  • This is reliant on good search techniques
  • Not starting from a blank slate is easier
  • Generate a selection list
  • Author still feels in control

Example Results for Podcasts
  • For a Podcast on Accessibility produced by CETL
    ALiC
  • One of the authors used the following key words
    and phrases
  • HCI
  • Accessibility
  • User centred design
  • Disability
  • Remember that different users will find different
    aspects of your interface difficult. For example
    users who are colour blind will not see colours
    as you intend and may not be able to distinguish
    between colours on the screen. You can test how
    your colours will look using an online simulator.
