The  Accessible Rich Internet Applications Working Group  invites implementations of two documents: WAI-ARIA Graphics Module (Graphics-ARIA) : Assistive technologies need semantic information about the structures and expected behaviors of a document in order to convey appropriate information to persons with disabilities. This specification defines a WAI-ARIA 1.1 [WAI-ARIA-1.1] module of core roles specific to web graphics. These semantics allow an author to express the logical structure of the graphic to assistive technologies in order improve accessibility of graphics. Assistive technologies could then enable semantic navigation and adapt styling and interactive features, to provide an optimal experience for the audience. These features complement the graphics and document structure elements defined by HTML [HTML52] and SVG [SVG2]. Graphics Accessibility API Mappings (Graphics-AAM) : The Graphics Accessibility API Mappings defines how user agents map the WAI-ARIA Graphic...

The  Internationalization Working Group  invites implementations of an updated Candidate Recommendation of  Encoding . The utf-8 encoding is the most appropriate encoding for interchange of Unicode, the universal coded character set. Therefore for new protocols and formats, as well as existing formats deployed in new contexts, this specification requires (and defines) the utf-8 encoding. The other (legacy) encodings have been defined to some extent in the past. However, user agents have not always implemented them in the same way, have not always used the same labels, and often differ in dealing with undefined and former proprietary areas of encodings. This specification addresses those gaps so that new user agents do not have to reverse engineer encoding implementations and existing user agents can converge.

20 March 2018 The  Web Authentication Working Group  invites implementations of the  Web Authentication: An API for accessing Public Key Credentials Level 1  Candidate Recommendation. This specification defines an API enabling the creation and use of strong, attested, scoped, public key-based credentials by web applications, for the purpose of strongly authenticating users. Conceptually, one or more public key credentials, each scoped to a given Relying Party, are created and stored on an authenticator by the user agent in conjunction with the web application. The user agent mediates access to public key credentials in order to preserve user privacy. Authenticators are responsible for ensuring that no operation is performed without user consent. Authenticators provide cryptographic proof of their properties to relying parties via attestation. This specification also describes the functional model for WebAuthn conformant authenticators, including their signatur...

The  Device and Sensors Working Group  invites implementations of the Candidate Recommendation for six documents, namely: Generic Sensor API : Generic Sensor API defines a framework for exposing sensor data to the Open Web Platform in a consistent way. It does so by defining a blueprint for writing specifications of concrete sensors along with an abstract Sensor interface that can be extended to accommodate different sensor types. Ambient Light Sensor : Ambient Light Sensor defines a concrete sensor interface to monitor the ambient light level or illuminance of the device’s environment. Accelerometer : Accelerometer defines  Accelerometer ,  LinearAccelerationSensor  and  GravitySensor  interfaces for obtaining information about acceleration applied to the X, Y and Z axis of a device that hosts the sensor. Gyroscope : Gyroscope defines a concrete sensor interface to monitor the rate of rotation around the device’s local three primary axes. Mag...

The  Timed Text Working Group  invites implementations of the  Timed Text Markup Language 2 (TTML2)  Candidate Recommendation. This document specifies the Timed Text Markup Language (TTML), Version 2, also known as TTML2, in terms of a vocabulary and semantics thereof. The Timed Text Markup Language is a content type that represents timed text media for the purpose of interchange among authoring systems. Timed text is textual information that is intrinsically or extrinsically associated with timing information.

The  CSS Working Group  has published a First Public Working Draft of  CSS Text Decoration Module Level 4 . This module contains the features of CSS relating to text decoration, such as underlines, text shadows, and emphasis marks. CSS  is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc.

An updated Working Draft of  Accessibility Conformance Testing (ACT) Rules Format  was published today by the  Accessibility Guidelines Working Group (AG WG) . This draft addresses all comments received on the previous draft. Most importantly, the “Selector” approach was replaced with “Applicability” and “Expectation” pairs, to make ACT Rules less procedural. This draft is accompanied by  sample ACT Rules  that implement this rules format. Read about the the  Web Accessibility Initiative (WAI) .

5 March 2018 The W3C Advisory Committee having  nominated  three individuals, is invited today to vote until 2 April 2018 for one seat in the 2018 special election to the W3C Technical Architecture Group (TAG) per  Process Document now granting an additional seat . The TAG is a special working group within the W3C, chartered under the  W3C Process Document , with stewardship of the Web architecture. Some aspects of its mission include to document and build consensus around principles of Web architecture and to interpret and clarify these principles when necessary; to resolve issues involving general Web architecture brought to the TAG; to help coordinate cross-technology architecture developments inside and outside W3C.

The  Web Performance Working Group  invites implementations of an updated 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.
