The Timed Text Working Group invites implementations of TTML Profiles for Internet Media Subtitles and Captions 1.0.1 (IMSC1) Candidate Recommendation. This document specifies two profiles of [TTML1]: a text-only profile and an image-only profile. These profiles are intended to be used across subtitle and caption delivery applications worldwide, thereby simplifying interoperability, consistent rendering and conversion to other subtitling and captioning formats. This revision of the IMSC1 adds two new features (ittp:activeArea and itts:fillLineGap) to the Recommendation dated 21 April 2016.

W3C Invites Implementations of Semantic Sensor Network Ontology
The Spatial Data on the Web Working Group invites implementations of Semantic Sensor Network Ontology Candidate Recommendation. The specification defines an ontology for describing sensors and their observations, the involved procedures, the studied features of interest, the samples used to do so, and the observed properties, as well as actuators.
SSN follows a horizontal and vertical modularization architecture by including a lightweight but self-contained core ontology called SOSA (Sensor, Observation, Sample, and Actuator) for its elementary classes and properties. With their different scope and different degrees of axiomatization, SSN and SOSA are able to support a wide range of applications and use cases, including satellite imagery, large-scale scientific monitoring, industrial and household infrastructures, social sensing, citizen science, observation-driven ontology engineering, and the Web of Things.
First Public Working Draft: CSS Fonts Module Level 4
The CSS Working Group has published a First Public Working Draft of CSS Fonts Module Level 4. Building on CSS Fonts 3, which defines the @font-face rule and provides OpenType feature support, CSS Fonts 4 add support for OpenType Variable fonts, and gives stylesheet designers a way to style the colors in chromatic (multicolored) fonts.
W3C Invites Implementations of HTML 5.1 2nd Edition
The Web Platform Working Group invites implementations of HTML 5.1 2nd Edition Candidate Recommendation. This specification defines the 5th major version, first minor revision of the core language of the World Wide Web: the Hypertext Markup Language (HTML). In this version, 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.
W3C Announces its First Publishing Summit and New Publishing Standards Work
W3C opened today registration for its first ever W3C Publishing Summit to be held 9-10 November 2017 in San Francisco, California, co-located with the W3C’s Technical Plenary and Advisory Committee meetings (TPAC 2017), and calls for speakers by 15 July 2017. The inaugural W3C Publishing Summit will show how publishers are using today’s Web technologies to make publications more effective and workflows more efficient.
W3C launched last week its new Publishing Working Group, just a few months following the combination of IDPF and W3C, with a mission to provide the necessary technologies on the Open Web Platform to make the combination of traditional publishing and the Web complete in terms of accessibility, usability, portability, distribution, archiving, offline access, and reliable cross referencing.

First Public Working Draft: CSS Overflow Module Level 4
The CSS Working Group has published a First Public Working Draft of CSS Overflow Module Level 4. This module contains the features of CSS relating to new mechanisms of overflow handling in visual media (e.g., screen or paper). In interactive media, it describes features that allow the overflow from a fixed size container to be handled by pagination (displaying one page at a time). It also describes features, applying to all visual media, that allow the contents of an element to be spread across multiple fragments, allowing the contents to flow across multiple regions or to have different styles for different fragments.
Verifiable Claims Use Cases Note Published
The Verifiable Claims Working Group has published the first draft of its Group Note, Verifiable Claims Uses Cases. In later drafts this document will serve to illustrate the scope of the work and to provide a focus for discussion; it has been republished as input from the earlier Community Group, which had a wider scope. An example of a verifiable claim might be that someone wanting to order medication online is over 18 years old, or that someone applying for a job has the appropriate degree and/or license to practice.
Cloud Browser Architecture Note Published
The Web and TV Interest Group has published a Group Note of Cloud Browser Architecture. A Cloud Browser is a browser running and executing on a server. This document describes the concepts and architecture for the Cloud Browser. The main purpose of this document is to provide the building blocks for a Cloud Browser solution.
XSL Transformations (XSLT) Version 3.0 is now a W3C Recommendation
The XSLT Working Group has published XSL Transformations (XSLT) Version 3.0 as a Recommendation. XSLT 3.0 enables transformations to be performed in streaming mode, where neither the source document nor the result document is ever held in memory in its entirety.
Another important enhancement is provided by XSL packages, to improve the modularity of large stylesheets, allowing stylesheets to be developed from independently-developed components with a high level of software engineering robustness.
XSLT 3.0 is designed to be used in conjunction with XPath 3.0, which offers higher-order functions. It also specifies the map functionality exactly as it is in the XPath 3.1 Recommendation, and implementors may also offer support for other XPath 3.1 additions compared to XPath 3.0, like arrays.
Call for Review: Shapes Constraint Language (SHACL) Proposed Recommendation published
The RDF Data Shapes Working Group has published a Proposed Recommendation of Shapes Constraint Language (SHACL). This document defines the SHACL Shapes Constraint Language, a language for validating RDF graphs against a set of conditions. These conditions are provided as shapes and other constructs expressed in the form of an RDF graph. RDF graphs that are used in this manner are called “shapes graphs” in SHACL and the RDF graphs that are validated against a shapes graph are called “data graphs”. Such descriptions may be used for a variety of purposes beside validation, including user interface building, code generation and data integration. Comments are welcome through 6 July 2017.
