Definition

The resource includes a table of contents that provides links to the major sections of the content.

Examples

Example 1 — EPUB 3
<meta property="schema:accessibilityFeature">
   tableOfContents
</meta>
Example 2 — EPUB 2
<meta name="schema:accessibilityFeature"
      content="tableOfContents"/>
Example 3 — Audiobooks
"accessibilityFeature": ["tableOfContents"]

Explanation

The tableOfContents value is used to indicate that a publication includes a table of contents for navigating the major sections of the work.

The table of contents is an important aid for navigating a publication for those who cannot see the text.

The table of contents is an integral part of formats like EPUB so is always expected to be present. Authors still need to ensure that the table of contents is sufficiently complete (e.g., includes at least all the top-level headings), otherwise it is incorrect to set this value.

See the table of contents knowledge base page for more information.
