Guideline 2.4 Provide mechanisms to help users find content, orient themselves within it, and navigate through it.

Level 1 Success Criteria for Guideline 2.4

  1. Navigational features can be programmatically determined. [I]

    Editorial note:

    This success criterion assumes that the fact that this has to be done in a standard and supported fashion for the technology will be covered by the definition of programmatically determined.

Level 2 Success Criteria for Guideline 2.4

  1. Multiple ways to locate specific content within a set of delivery units are available.[V]

    Editorial Note: "Locate" is intended to mean both finding the content and being able to get to it. The working group would like to receive input on whether both intended meanings are clear to the users of the guidelines.

  2. Blocks of material that are repeated on multiple perceivable units are implemented so that they can be bypassed. [V]

    Editorial Note: General Techniques might include something about satisfying this criterion through metadata, use of a future role attribute, etc.

  3. Delivery units have descriptive titles [I]
  4. For each programmatic reference to another delivery unit, a title or description of that delivery unit can be programatically determined.

Level 3 Success Criteria for Guideline 2.4

  1. When a page or other delivery unit is navigated sequentially, elements receive focus in an order that follows relationships and sequences in the content. [I]

Changes and rationale

This section discusses the changes between the current working draft (November 19, 2004 version) and this proposal. Several changes are the result of us striving to clarify the distinction between 2.4 and 1.3. In the new proposal we focus on what's necessary to support navigation, orientation and finding content.
