Group Notes: Extensions to the OWL-Time Ontology — entity relations & temporal aggregates

The Spatial Data on the Web Interest Group has published two First Public Interest Group Notes:

OWL-Time [owl-time] is an ontology for temporal entities and relations between them. OWL-Time defines simple temporal entities (intervals and instants). The entity relations note adds four new relations: time:equals, time:hasInside, time:disjoint and time:notDisjoint which complement the original relations and allow for description of more relationships between temporal entities. The temporal aggregates note adds one new class time:TemporalAggregate and two properties time:hasPart and its inverse time:isPartof to allow for the description of arbitrary aggregates of temporal entities.

New Resource: Authoring Tool Accessibility Report Generator

The Accessibility Education and Outreach Working Group (EOWG) has published the ATAG Report Tool. Authoring tools are software and services used to create web content – such as content management systems (CMS) and what-you-see-is-what-you-get (WYSIWYG) HTML editors. W3C’s Authoring Tool Accessibility Guidelines (ATAG) addresses making the authoring tools themselves accessible and helping authors create more accessible web content. Learn more from the ATAG Overview. The new ATAG Report Tool helps authoring tool vendors and evaluators provide information to project managers, procurers, and others who need to know how well potential authoring tools support accessibility.

Updated Working Draft: Challenges with Accessibility Guidelines Conformance and Testing, and Approaches for Mitigating Them

The Accessibility Guidelines Working Group (AG WG) has published an updated Working Draft of Challenges with Accessibility Guidelines Conformance and Testing, and Approaches for Mitigating Them. This document is part of work on future accessibility guidelines, including WCAG 3.0. It explores the challenges of evaluating a broad range of websites and applications for conformance to Web Content Accessibility Guidelines (WCAG), and explores approaches for mitigating these challenges. Please see the blog post for information on this document and questions for review: Challenges with Accessibility Guidelines Conformance and Testing, and Approaches for Mitigating Them – blog.

Call for Review: TTML Profiles for Internet Media Subtitles and Captions 1.2 is a W3C Proposed Recommendation

The Timed Text Working Group has published a Proposed Recommendation of TTML Profiles for Internet Media Subtitles and Captions 1.2. This specification defines two profiles of [ttml2]: 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.

Comments are welcome through 28 July 2020.

Updated Candidate Recommendation: Web Audio API

The Audio Working Group invites implementation of its updated Candidate Recommendation of Web Audio API. This specification describes a high-level Web API for processing and synthesizing audio in web applications. The primary paradigm is of an audio routing graph, where a number of AudioNode objects are connected together to define the overall audio rendering. The actual processing will primarily take place in the underlying implementation (typically optimized Assembly / C / C++ code), but direct script processing and synthesis is also supported.

First Public Working Draft: Rules for Simple Placement of Japanese Ruby

The Internationalization Working Group has published a First Public Working Draft of Rules for Simple Placement of Japanese Ruby. This document provides a simple set of rules for placement of Ruby text in Japanese typography that can be used as a minimum baseline for implementers and specification writers. It was developed by the JLReq (Japanese Layout) Task Force as a companion to Requirements for Japanese Text Layout 日本語組版処理の要件(日本語版).

Ruby is the name given to the small annotations in Japanese content that are rendered alongside base text, usually to provide a pronunciation guide, but sometimes to provide other information.

W3C Advisory Committee Elects Advisory Board

Logo for the W3C Advisory BoardThe W3C Advisory Committee has filled five open seats on the W3C Advisory Board. Beginning 1 July 2020, the following new elected participants, Tantek Çelik (Mozilla), Tatsuya Igarashi (Sony), Florian Rivoal (W3C Invited Expert), Tzviya Siegman (Wiley) and David Singer (Apple), will join continuing participants Elika J Etemad (W3C Invited Expert), Avneesh Singh (DAISY Consortium), Eric Siow (Intel), Léonie Watson (TetraLogical), Chris Wilson (Google) and Hongru (Judy) Zhu (Alibaba). Many thanks to Jay (Junichi) Kishigami (NTT) and Charles Nevile (ConsenSys), whose terms end this month.

Created in March 1998, the Advisory Board provides ongoing guidance to the W3C Team on issues of strategy, management, legal matters, process, and conflict resolution. The Advisory Board also serves the W3C Members by tracking issues raised between Advisory Committee meetings, soliciting Member comments on such issues, and proposing actions to resolve these issues. The Advisory Board manages the evolution of the Process Document. The Advisory Board hears appeals of Member Submission requests that are rejected for reasons unrelated to Web architecture. For several years, the AB has conducted its work in a public wiki.

The elected Members of the Advisory Board participate as individual contributors and not representatives of their organizations. Advisory Board participants use their best judgment to find the best solutions for the Web, not just for any particular network, technology, vendor, or user. Read more about the Advisory Board.
