Publication Manifest and Audiobooks are W3C Recommendations
The Publishing Working Group has published the following specifications as W3C Recommendations:
- Publication Manifest defines a general manifest format for expressing information about a digital publication. It uses schema.org metadata augmented to include various structural properties about publications, serialized in JSON-LD, to enable interoperability between publishing formats while accommodating variances in the information that needs to be expressed.
- Audiobooks describes the requirements for the creation of audiobooks, using a profile of the Publication Manifest specification.
