Coverage and Quality Reports

About These Reports

The APG Task Force uses the reports on this page to help plan content improvements. The reports provide data about the scope and quality of content in the APG. The data delineates:

Which ARIA attributes (roles, states, or properties) have usage demonstrated by an example.
Which ARIA attributes have usage guidance provided by a pattern or practice.
Which ARIA attributes are not covered by APG guidance or examples.
Which APG examples implement specific coding practices specified in the APG code guide.

The data in the reports are generated by a script that is run by a GitHub action workflow when the main branch of the aria-practices repository is updated. The script will indicate that an ARIA attribute has guidance in a pattern or practice if any of the following conditions are met:

The ARIA attribute is included in the text of a heading (e.g. h2-h6) within the content of a pattern or practice.
The ARIA attribute is included within either the data-aria-roles or data-aria-props attribute specified on a heading within a pattern or practice. These data attributes may contain a space separated list of values.

If either of the data attributes is specified on a heading, the content of that heading will not be processed. In the generated report, the suffix "(D)" indicates a reference came from a data attribute, otherwise the reference came from the text content of a heading.

The following files and reports are generated:
