Updated Candidate Recommendation for CSS Cascading and Inheritance Level 3

The Cascading Style Sheets (CSS) Working Group has published an updated Candidate Recommendation of CSS Cascading and Inheritance Level 3. This CSS module describes how to collate style rules and assign values to all properties on all elements. By way of cascading and inheritance, values are propagated for all properties on all elements. CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc. Learn more about the Style Activity.

Four Drafts Published by the CSV on the Web Working Group

The CSV on the Web Working Group has published a new set of Working Drafts, which the group considers feature complete and implementable.

The group is keen to receive comments on these specifications, either as issues on the Group’s GitHub repository or by posting to public-csv-wg-comments@w3.org.

The CSV on the Web Working Group would also like to invite people to start implementing these specifications and to donate their test cases into the group’s test suite. Building this test suite, as well as responding to comments, will be the group’s focus over the next couple of months.

First Public Working Draft: Web Payments Use Cases 1.0

Today the Web Payments Interest Group published a first draft of Web Payments Use Cases. The current payment landscape is changing rapidly, offering new opportunities for greater security, improved usability on mobile, and payment innovations in areas like digital wallets and cryptocurrencies. The lack of open standards for integrating the latest developments into the Web makes it more difficult for merchants, Web developers, and payment service providers to adapt to new payment solutions. Fragmented regulatory environments further complicate the payments landscape.

To achieve greater interoperability among merchants and their customers, payment providers, software vendors, mobile operators, and payment networks, the W3C Web Payments Interest Group, launched in October 2014, is developing a roadmap for standards to improve the interoperability of payments on the Web. Today’s use cases document establishes the group’s initial scope of work. Guided by these use cases, the W3C Web Payments Interest Group (see the current participants) plans to derive architecture and associated technology requirements. That work will form the basis of conversations with W3C groups and the broader payments industry about what standards (from W3C or other organizations) will be necessary to fulfill the use cases and achieve the full potential of Web payments.

Requirements for Hangul Text Layout and Typography Draft Published

The Internationalization Working Group has published a Working Draft of Requirements for Hangul Text Layout and Typography. This document describes requirements for general Korean language/Hangul text layout and typography realized with technologies like CSS, SVG and XSL-FO. The document is mainly based on a project to develop the international standard for Korean text layout. Learn more about the Internationalization Activity.

First Public Working Draft: SHACL Use Cases and Requirements

The RDF Data Shapes Working Group has published a Working Draft of SHACL Use Cases and Requirements. To foster the development of Shapes Constraint Language (SHACL), this document includes a set of use cases and requirements that motivate a simple language and semantics for formulating structural constraints on RDF graphs. All use cases provide realistic examples describing how people may use structural constraints to validate RDF instance data. Note, this document avoids the use of any specific vocabulary that might be introduced by the SHACL specification. Learn more about the Data Activity.

WOFF File Format 2.0; WOFF 2.0 Evaluation Report Drafts Published

The WebFonts Working Group has published a Working Draft of WOFF File Format 2.0. Based on experience with WOFF 1.0, which is widely deployed, this specification was developed to provide improved compression and thus lower use of network bandwidth, while still allowing fast decompression even on mobile devices. This is achieved by combining a content-aware pre-processing step and improved entropy coding, compared to the Flate compression used in WOFF 1.0.

The Group also published a Working Draft of WOFF 2.0 Evaluation Report. Web Open Font Format (WOFF) 2.0 is a proposed update to the existing WOFF 1.0 with improved compression. This report lists requirements for successful deployment, evaluates how the requirement may be met, and examines the compression gains and tradeoffs vs. code complexity, encode and decode time. This document is non-normative. Learn more about the Fonts Activity.
