Description

The objective of this technique is to provide a mechanism for locating a glossary. When terms in the content are defined on a separate glossary page, the glossary is referenced using a link element in the head element of the document that uses the glossary. The rel attribute of the link element is set to "glossary", and the href attribute contains the URI of the glossary page. User agents can then assist users in accessing the glossary quickly and easily.

Examples

Example 1: The WCAG 2.0 Glossary.

 <link rel="glossary" href="https://www.w3.org/TR/WCAG20/#glossary">

For any set of words and their definitions that are meant to serve as a glossary:

  1. Check that the head section of the Web page that contains words, phrases or abbreviations defined in a glossary contains a link element
  2. Check that the link element has attribute rel="glossary"
  3. Check that the href attribute of the link element refers to the glossary page.

Expected Results
