W3C

The W3C Advisory Committee has filled four open seats on the W3C Advisory Board. Created in 1998, the Advisory Board provides guidance to the Team on issues of strategy, management, legal matters, process, and conflict resolution. Beginning 1 July 2017, the nine Advisory Board participants are Tantek Çelik (Mozilla), Michael Champion (Microsoft), Virginie Galindo (Gemalto), Jay (Junichi) Kishigami (NTT), Charles McCathie Nevile (Yandex), Natasha Rooney (GSMA), David Singer (Apple), Léonie Watson (The Paciello Group) and Judy Zhu (Alibaba). Many thanks to Chris Wilson (Google), whose term ends this month. Read more about the Advisory Board.

Digital Publishing Accessibility API Mappings (DPub-AAM) has been published as a Candidate Recommendation by Accessible Rich Internet Applications (ARIA) Working Group and is now undergoing implementation finalization and testing. DPub-AAM describes how roles in the Digital Publishing WAI-ARIA Module 1.0 should be exposed to accessibility APIs. Implementation of this specification makes it possible for assistive technologies to provide enhanced navigation among landmarks unique to digitally-published documents, and to identify document-specific features which should be presented to the user, such as crossing a page boundary. These mappings will also be used in part for verifying implementation success of Digital Publishing WAI-ARIA Module 1.0 which is already a Candidate Recommendation. The draft implementation report shows the progress of testing. Please send implementation information or comments by 7 July 2017. Read about the Web Accessibility Initiative (WAI).

The Accessible Rich Internet Applications (ARIA) Working Group has published a First Public Working Draft of Personalization Semantics 1.0. Personalization involves tailoring aspects of the user experience to meet the needs and prefences of the user. The introduction of standardized semantics allows web applications to customize the exposure of that content to one that is familiar to individuals based on their needs and preferences. This specification was initially developed in a task force to provide technology features needed to meet needs of users with cognitive or learning disabilities, but is intended to support a wide variety of personalization use cases. Please comment by filing GitHub issues in the personalization semantics repository or, if this is not feasible, by email to public-aria@w3.org, by 30 June 2017.

The Spatial Data on the Web Working Group invites implementations of Time Ontology in OWL Candidate Recommendation. The ontology provides a vocabulary for expressing facts about topological (ordering) relations among instants and intervals, together with information about durations, and about temporal position including date-time information. Time positions and durations may be expressed using either the conventional (Gregorian) calendar and clock, or using another temporal reference system such as Unix-time, geologic time, or different calendars.

The Second Screen Working Group has published a revised Candidate Recommendation of the Presentation API. That specification defines an API to enable Web content to access presentation displays and use them for presenting Web content.

Since publication as Candidate Recommendation in July 2016, the Working Group updated algorithms in the specification to fix issues identified through testing and implementation feedback. The actual interfaces did not change. The API was also restricted to secure contexts. A complete list of changes is available.

The Web Platform Working Group invites implementation of UI Events KeyboardEvent code and key Values:

• UI Events KeyboardEvent code Values: This document provides an overview of the various keyboard layouts and specifies the KeyboardEvent.code values that should be used for each of the keys. Unlike the key values described in UIEvents-key, the code values are based only on the key’s physical location on the keyboard and do not vary based on the user’s current locale. This specification was formerly titled DOM Level 3 KeyboardEvent code Values.
• UI Events KeyboardEvent key Values: This document specifies the set of valid key attribute values that must be used in the KeyboardEvent.key attribute to encode the key’s meaning. The key value for a particular key will differ based on the user’s current locale setting.

The Social Web Working Group has published ActivityStreams 2.0 as a Recommendation. AS2 provides a JSON data model and vocabulary for representing common online social objects, activities, and the relationships between them. AS2 is anticipated to become the de-facto standard for sharing social data between disparate (perhaps decentralized) Social Web applications, and builds on the well-used ActivityStreams 1.0. The AS2 Vocabulary provides a core set of terms, which are extensible using JSON-LD, and extensions may be made stable by means of the Social Web Incubator Community Group. AS2 may be used as part of any protocol, but the Social Web Working Group is developing ActivityPub specifically for AS2-based client-to-server and server-to-server interactions.
