The Web Platform Working Group invites implementations of Indexed Database API 2.0 Candidate Recommendation. This specification is the Second Edition of Indexed Database API. The First Edition became a W3C Recommendation on 8 January 2015.

This document defines APIs for a database of records holding simple values and hierarchical objects. Each record consists of a key and some value. Moreover, the database maintains indexes over records it stores. An application developer directly uses an API to locate records either by their key or by using an index. A query language can be layered on this API. An indexed database can be implemented using a persistent B-tree data structure.

The Web Platform Working Group invites implementations of HTML 5.2 Candidate Recommendation. This specification defines the 5th major version, second minor revision of the core language of the World Wide Web: the Hypertext Markup Language (HTML). In this version, new features continue to be introduced to help Web application authors, new elements continue to be introduced based on research into prevailing authoring practices, and special attention continues to be given to defining clear conformance criteria for user agents in an effort to improve interoperability.

The CSS Working Group invites implementations of CSS Containment Module Level 1 Candidate Recommendation. This CSS module describes the ‘contain’ property, which indicates that the element’s subtree is independent of the rest of the page. This enables heavy optimizations by user agents when used well.

CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc.

The Web Platform Working Group has published a Proposed Recommendation of HTML 5.1 2nd Edition.

In this version, a significant error with HTML 5.1 has been rectified, as noted in the Errata corrected section.

Comments are welcome through 31 August 2017.

The Web Performance Working Group invites implementations of a revised Candidate Recommendation of High Resolution Time Level 2. This specification defines an API that provides the time origin, and current time in sub-millisecond resolution, such that it is not subject to system clock skew or adjustments. This publication updates the High Resolution Time Level 2 to include the material from the previous Working Draft of High Resolution Time Level 3. In practice, this bring the timeOrigin attribute into Level 2.

The Verifiable Claims Working Group has published a First Public Working Draft of Verifiable Claims Data Model and Representations. Driver’s licenses are used to claim that we are capable of operating a motor vehicle, university degrees can be used to claim our education status, and government-issued passports enable holders to travel between countries. This specification provides a standard way to express these sorts of claims on the Web in a way that is cryptographically secure, privacy respecting, and automatically verifiable.
