The W3C Technical Architecture Group (TAG) has published a First Public Working Group Note of Web Platform Design Principles. This document contains a set of design principles to be used when designing Web Platform technologies. These principles have been collected during the Technical Architecture Group’s discussions in reviewing developing specifications. We encourage specification designers to read this document and use it as a resource when making design decisions.

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.
