    Quick Facts

    • The document provides techniques for displaying accessibility metadata from ONIX (the standard for describing book products) to end users.
    • ONIX metadata can be used to display accessibility information before the actual publication is available or when the file metadata cannot be accessed directly.
    • There is no 1:1 mapping between ONIX accessibility metadata and EPUB accessibility metadata, so direct translation may not always be possible.
    • The document provides specific examples for extracting accessibility information, such as screen reader friendliness, full audio, accessibility summary, conformance levels, certification details, and hazard warnings, from ONIX records.
    • ONIX has a number of new accessibility metadata codes in version 3.0 that may not be expressible in earlier versions.
    • The document recommends referring the EPUB to the ONIX crosswalk for a complete list of ONIX accessibility metadata.
    • Displaying accessibility metadata from ONIX can complement the accessibility data embedded directly within the publication.
    • ONIX only describes the product, not the reading system capabilities, so both ONIX and file-level metadata should be used together.
    • The document provides practical examples and techniques for implementing the User Experience Guide for Displaying Accessibility Metadata.
    • The Publishing Community Group published this specification. It is not a W3C Standard or on the W3C Standards Track.
