This document crosswalks the accessibility metadata for Schema.org, EPUB, and ONIX.
The following table provides a crosswalk between the properties defined in the EPUB Accessibility specification [[EPUB-A11Y-11]] and the equivalents defined in the ONIX metadata standard [[ONIX]].
The conformsTo
term used in EPUB is drawn from Dublin
Core.
Unless stated otherwise, all code values are from ONIX code list 196.

List 81, Code 10: "Text (eye-readable)" combined with List 196, Code 10: "No reading system accessibility options disabled (except)" means all text is actual text. Note that List 81, Code 10 on its own (without List 196, Code 10) admits the possibility that the "text" is inaccessible because it is an image of text. |
|
accessModeSufficient | |
ONIX crosswalks are for instances where accessModeSufficient includes this vocabulary entry alone; combinations may occur but are more difficult to crosswalk | |
