Issues migrating to overseas partners l.jpg

Issues: Migrating to overseas partners

  • Commercial partners did not want an xml export of metadata

  • Several had never heard of xml

  • Picture libraries receive thousands of image records every week from hundreds of different sources.

  • Which xml standard ?


Courtauld institute l.jpg

Courtauld Institute

  • NOF project team created powerful, sophisticated DAM

  • Day-to-day activities not integrated into project

  • Most staff prefer to use known, pre-existing, simple Access databases

  • Locked-in images/ data

  • Authority lists - ULAN and Witt


Keywords and thesaurii l.jpg

Keywords and thesaurii

Keyword Search

  • “Select a keyword below to initiate a new search”

  • Keywords: portraits, books, finger rings, busts

  • Keywording done via thesaurii

  • Ensures consistency, but not designed to enable unmediated searches

  • Poor results on common general searches

The role of funders l.jpg

The role of funders

To make more precise demands of the recipients of their funds, in order to:

  • Ensure digital preservation

  • Ensure the rights information is harvested

  • Ensure digital asset creation

  • Pay more than lip service to the idea of sustainablity and re-purposing
