Notes

  1. Strength. Reveal is not using this attribute at present but expects to do so in the future. It is not used at present because of the difficulty of finding a suitable method of describing the strength of varying types of collections. Some collections cover all subject areas to a similar level; such collections may have a few hundred items or several thousand. There are also some very small collections which have no focus (collection with 6 items comprising 2 novels, 1 non-fiction title on history, 1 exam paper on French, a single poem, and a tactile map).
  2. Subject. Reveal has defined a minimal set of terms for initial use: Fiction, Non-fiction, Serials and Music scores. In the longer term, Reveal is considering applying terms from an approved set of subject terms (e.g. LCSH) for more detailed terms, but the same constraints apply as in note 1.
  3. A number of attributes are marked 'not publicly displayed'. These attributes can only be viewed by Reveal staff and Reveal partners when logged on to the edit function using password protected login.

Accessibility issues

Visually impaired users searching the database will be using a variety of methods to assist them. High screen magnification reduces the area of the screen that is visible at any point, and speech synthesis software and braille output both produce a linearly structured data sequence. If the data is a list of options, the user must remember the options to be able to select one.

One consequence of this is that any list for them to select from should present no more than 7 options at any time. This will affect design of areas such a Concept searching (more than 7 concepts) - so need some way of using a hierarchical structure. Also applies to Available Media searching.

This is in addition to the Web accessibility issues.
