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

• Model for Tabular Data and Metadata on the Web: an abstract model for tabular data, and how to locate metadata that enables users to better understand what the data holds; this specification also contains non-normative guidance on how to parse CSV files
• Metadata Vocabulary for Tabular Data: a JSON-based format for expressing metadata about tabular data to inform validation, conversion, display and data entry for tabular data
• Generating JSON from Tabular Data on the Web: how to convert tabular data into JSON
• Generating RDF from Tabular Data on the Web: how to convert tabular data into RDF

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.

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.

The Web Applications Working Group has published a Working Draft of Gamepad. The Gamepad specification defines a low-level interface that represents gamepad devices. Learn more about the Rich Web Client Activity.

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.

The HTML Working Group has published a Working Draft of ARIA in HTML. This specification defines the web developer rules (author conformance requirements) for the use of wai-aria-1.1 attributes on HTML51 elements. It also defines requirements for Conformance Checking tools. Learn more about the HTML Activity.

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.

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.

The Web Real-Time Communications Working Group and Device APIs Working Group have published a Last Call Working Draft of Media Capture and Streams. This document defines a set of JavaScript APIs that allow local media, including audio and video, to be requested from a platform. Comments are welcome through 15 May 2015. Learn more about the Ubiquitous Web Applications Activity.
