Accessibility Metadata Announcement

Great news on accessibility metadata through Schema.org: a revision 3.2 has been released and our new accessibility metadata is included, which the EPUB Accessibility 1.0 specification relies on upon!  Not only did all 3 new vocabulary terms get added but they got added to the core itself.  The new terms are accessMode, accessModeSufficient, and accessibilitySummary.   This builds on the previous 4 metadata vocabulary terms that the Accessibility MetaData Project produced. This announcement is another step toward making it easier for people to find accessible content suited for their needs.
