W3C

The Automotive Working Group has published the following two First Public Working Drafts:

• VSSo Core: Vehicle Signal Specification Core Ontology: The core ontology introduces concepts for the structural elements of VSS defined through the rule set in the specifications. The core of the ontology defines this structure in an OWL ontology and serves as a basis for the defined signals of the standard catalogue and potential further development of the branches as more than structural information.
• VSSo: Vehicle Signal Specification Ontology: As the core ontology defined the structure, VSSo holds the vocabulary as defined by the standard catalogue. The main objective is, that VSSo doesn’t diverege from the standard catalogue, so this is done automatically through tooling provided in the corresponding repository. The tooling takes the standard catalogue and maps it to concepts defined in the core ontology. The result is an OWL complient ontology, following the standard catalogue of VSS.

The Verifiable Credentials Working Group has just updated the W3C Recommendation of Verifiable Credentials Data Model v1.1. Credentials are a part of our daily lives; driver’s licenses are used to assert that we are capable of operating a motor vehicle, university degrees can be used to assert our level of education, and government-issued passports enable us to travel between countries. This specification provides a mechanism to express these sorts of credentials on the Web in a way that is cryptographically secure, privacy respecting, and machine-verifiable.

The Devices and Sensors Working Group invites implementations of Geolocation API. The Geolocation API provides access to geographical location information associated with the hosting device.

The CSS Working Group invites implementations of CSS Conditional Rules Module Level 4. This module contains the features of CSS for conditional processing of parts of style sheets, based on capabilities of the processor or the environment the style sheet is being applied in. It includes and extends the functionality of CSS Conditional 3 [css-conditional-3], adding the ability to query support for particular selectors [SELECTORS-4] through the new selector() notation for supports queries.

Comments are welcome as GitHub issues by 17 April 2022.

The Second Screen Working Group Patent Advisory Group (PAG), launched in August 2021 in response to disclosures related to a specification of the Second Screen Working Group, has issued an Update to the Call for Prior Art to seek prior art that is available in the public domain or on terms consistent with W3C’s Royalty-Free Licensing Requirements. The update contains questions about prior art related to digital audio, digital imaging, and multimedia networking technology from the mid-2000s.

Feedback should be directed to group-secondscreen-prior-art@w3.org by 31 March 2022. For more information about the Second Screen Working Group PAG, see its home page and charter.

The CSS Working Group invites implementations of CSS Color Adjustment Module Level 1. This module introduces a model and controls over automatic color adjustment by the user agent to handle user preferences, such as “Dark Mode”, contrast adjustment, or specific desired color schemes.

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

The National Academy of Arts and Sciences has released its 2021 list of Technology & Engineering Emmy® Awards today and we were delighted to discover that the Web Fonts Working Group, along with MPEG, will be honored for standardizing font technology for custom downloadable fonts and typography for web and TV devices.

This award represents the culmination of a quarter-century of work at W3C. Web Fonts enable people to use fonts on demand over the web without requiring installation in the operating system. W3C has experience in downloadable fonts through HTML, CSS2, and SVG. Downloadable fonts were not common on the web due to the lack of an interoperable font format. The Web Fonts effort addresses that through the creation of an industry-supported, open font format for the web called “WOFF” (Web Open Font Format) whose version 2, which became a standard in 2018, is deployed in all major web browsers and powers a vast majority of sites.

This is the third Emmy® Award in Technical & Engineering W3C has won. We will be working with our colleagues to send delegates to the ceremony that will be part of the National Association of Broadcasters (NAB) show in Las Vegas on April 25, 2022.

The Technology & Engineering Emmy® Awards are awarded to a living individual, a company, or a scientific or technical organization for developments and/or standardization involved in engineering technologies that either represent so extensive an improvement on existing methods or are so innovative in nature that they materially have affected television.
