These requirements were used to evaluate Digital Repository Architecture Alternatives. Now that Fedora has been selected, this list is mostly of historical importance.

User requirements

  1. DLP staff can easily create new collections.
  2. DLP staff can easily manage existing collections.
  3. Faculty members, librarians, and others outside the DLP can easily create
    collections using DLP-supported resources.
  4. Other digital library professionals can easily index, search, and obtain
    metadata in DLP collections.

  1. Wiki Markup
    \[*Must*\] The repository is able to store/search/deliver both text-centric and
      image-centric collections.

  12. Wiki Markup
    \[*Must*\] The repository is able to manage data at many levels of granularity.
  13. Wiki Markup
