Accessibility metadata allows users to assess whether a digital book meets their specific needs before purchasing it. In specific circumstances, accessibility metadata may not completely reflect your efforts or potential limitations. In this case, a specific field allows you to directly write a short text describing what is not represented by other metadata.

Objectives

• Improve accessibility of content to readers with disabilities.
• Allow distribution platforms to better report the accessibility characteristics of works.

Implementation

• Write the content of the accessibilitySummary element for the OPF file.
• Write the content of the ONIX code 196-92 Addendum on accessibility.

Control

• Verify the presence and relevance of an accessibility summary in the digital book’s OPF file.
• Verify the presence and relevance of a pertinent Accessibility Addendum in the ONIX record (code 196-92).
• Verify that accessibility information is correctly displayed on online bookstore product pages.
