H60: Using the link element to link to a glossary

Important Information about Techniques

See Understanding Techniques for WCAG Success Criteria for important information about the usage of these informative techniques and how they relate to the normative WCAG 2.0 success criteria. The Applicability section explains the scope of the technique, and the presence of techniques for a specific technology does not imply that the technology can be used in all situations to create content that meets WCAG 2.0.



This technique relates to:

User Agent and Assistive Technology Support Notes

See User Agent Support Notes for H60.


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.


Example 1: The WCAG 2.0 Glossary.

Example Code:

 <link rel="glossary" href="">

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

Note: The definition of abbreviation used in WCAG is : "shortened form of a word, phrase, or name where the original expansion has not been rejected by the organization that it refers to and where the abbreviation has not become part of the language."

If this is a sufficient technique for a success criterion, failing this test procedure does not necessarily mean that the success criterion has not been satisfied in some other way, only that this technique has not been successfully implemented and can not be used to claim conformance.
