HTML 5.1 2nd Edition is a W3C Recommendation

HTML5 logoThe Web Platform Working Group has published a W3C Recommendation of HTML 5.1 2nd Edition. This specification defines the 2nd edition of the 5th major version, first minor revision of the core language of the World Wide Web: the Hypertext Markup Language (HTML). In this version, a significant error with HTML 5.1 has been rectified, as noted in the Errata corrected section. Meanwhile, 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 in the development of HTML 5.2.

W3C Invites Implementations of ODRL Information Model; ODRL Vocabulary & Expression

The Permissions & Obligations Expression Working Group has just published two Candidate Recommendations, namely:

  • ODRL Information Model—The Open Digital Rights Language (ODRL) is a policy expression language that provides a flexible and interoperable information model, vocabulary, and encoding mechanisms for representing statements about the usage of content and services. The ODRL Information Model describes the underlying concepts, entities, and relationships that form the foundational basis for the semantics of the ODRL policies. Policies are used to represent permitted and prohibited actions over a certain asset, as well as the obligations required to be meet by stakeholders. In addition, policies may be limited by constraints (e.g., temporal or spatial constraints) and duties (e.g. payments) may be imposed on permissions.
  • ODRL Vocabulary & Expression—The ODRL Vocabulary and Expression describes the terms used in ODRL policies and how to encode them.

Candidate Recommendation means that the Working Group considers the technical design to be complete, and is seeking implementation feedbacks on the documents. There is a separate document how to use them and report on implementation results. The group welcomes feedback by email to its public mailing list public-poe-comments@w3.org or as issues raised in the issues on the Group’s GitHub repository

The group expects to satisfy the implementation goals (i.e., at least two, independent implementation for each of the test cases) by November 14, 2017.

W3C Invites Implementations of Core Accessibility API Mappings 1.1

Core Accessibility API Mappings (Core-AAM) 1.1 has been published by Accessible Rich Internet Applications (ARIA) Working Group as a Candidate Recommendation and is now undergoing implementation finalization and testing. Core-AAM describes how roles, states, and properties in Accessible Rich Internet Applications (WAI-ARIA) 1.1 should be exposed to accessibility APIs. Implementation of this specification makes it possible for users with disabilities to obtain and interact with information using assistive technologies. These mappings will also be used in part for verifying implementation success of WAI-ARIA 1.1 which is already a Candidate Recommendation. The draft implementation report shows the progress of testing. Please send implementation information or comments by 19 October 2017. Read about the Web Accessibility Initiative (WAI).

Encrypted Media Extensions (EME) is a W3C Recommendation

illustration of movies on the Web showing a ticketThe HTML Media Extensions Working Group published Encrypted Media Extensions (EME) as a W3C Recommendation today. Encrypted Media Extensions (EME), which extends the ‘HTMLMediaElement’ element of the HTML specification, is an Application Programming Interface (API) that allows playback of protected content in Web browsers. Combined with W3C’s Recommendation Media Source Extensions (MSE) which provides the API for streaming video, EME is the most common practice today that allows Web developers to stop using plugins to deliver commercial quality video over the Web. Please read more in our Press Release.

First Public Working Drafts: WoT Architecture; WoT Thing Description; WoT Scripting API

The Web of Things (WoT) Working Group has published the following three First Public Working Drafts:

Web of Things (WoT) Architecture: This document describes the abstract architecture for the W3C Web of Things, which consists of three initial building blocks, i.e., (1) WoT Thing Description, (2) WoT Scripting API and (3) WoT Binding Templates.

Web of Things (WoT) Thing Description: This document describes a formal model and common representation for a Web of Things Thing Description. A Thing Description describes the metadata and interfaces of Things, where a Thing is an abstraction of a physical entity that provides interactions to and participates in the Web of Things.

Web of Things (WoT) Scripting API: This document describes a programming interface representing the WoT Interface that allows scripts run on a Thing to discover and consume (retrieve) other Things and to expose Things characterized by Properties, Actions and Events.

The group is planning to publish the third building block, WoT Binding Templates, as a First Public Working Draft shortly.

W3C Invites Implementations of Payment Request API; Payment Method Identifiers

The World Wide Web Consortium (W3C) today called for broad implementation and testing of Web technologies to make online checkout easier for users and improve conversions and security for merchants. All major browser makers are now implementing Payment Request API and Payment Method Identifiers, which today advanced to Candidate Recommendation Status. The Web Payments Working Group encourages merchants, Web developers, and users to experiment with these early implementations and provide feedback to the group. In parallel, the Working Group will be expanding its test suite for the API to help ensure browser interoperability. Read more in the W3C Media Advisory and blog post.
