Explanation

Code 00 is used to provide a summary of the accessibility of a digital publication.

The summary provided in this field corresponds to the accessibility summary as defined in the EPUB Accessibility 1.0 specification. That is, it duplicates information such as the conformance statement and accessibility features of the publication.

Note

For publications that conform to EPUB Accessibility 1.1 or above — where the summary is not supposed to reproduce information expressed in the other accessibility metadata — use Code 92 instead.

The value of this field is the same as would be expressed in the Schema.org accessibilitySummary property.

The field is often limited to 500 characters.

Only for use in ONIX 3.0 or later.
