The Accessible Rich Internet Applications Working Group has published a Proposed Recommendation of Accessible Name and Description Computation 1.1. This document describes how user agents determine the names and descriptions of accessible objects from web content languages. This information is in turn exposed through accessibility APIs so that assistive technologies can identify these objects and present their names or descriptions to users. Documenting the algorithm through which names and descriptions are to be determined promotes interoperable exposure of these properties among different accessibility APIs and helps to ensure that this information appears in a manner consistent with author intent.

Comments are welcome through 16 November 2018.
The Pointer Events Working Group has published a Proposed Recommendation of Pointer Events Level 2. The features in this specification extend or modify those found in Pointer Events, a W3C Recommendation that describes events and related interfaces for handling hardware agnostic pointer input from devices including a mouse, pen, touchscreen, etc. For compatibility with existing mouse based content, this specification also describes a mapping to fire Mouse Events for other pointer device types.

W3C announced today a Workshop on Web Standardization for Graph Data, 4-6 March 2019, in Berlin, Germany. The event is hosted by Neo4J.
This workshop brings together people with an interest in the future of standards relating to graph data, and its ever growing importance in relation to the Internet of Things, smart enterprises, smart cities, etc., open markets of services, and synergies with Artificial Intelligence and Machine Learning (AI/ML).
The scope includes:
Harmonising different perspectives on database management systems:
- The role of annotations, e.g. spatial, temporal, provenance, data quality, trust, etc. and opportunities for extending RDF to better support them;
- the relationship between RDF and other related approaches, e.g. Labelled Property Graphs and work by ETSI ISG CIM;
- requirements for graph query and update languages and
- requirements for rule languages for graph data.
Managing the silos, big data, AI and machine learning:
- Techniques for dealing with incomplete, uncertain and inconsistent knowledge;
- different kinds of reasoning, e.g. deductive, inductive, abductive, analogical, spatial, temporal, causal, social, and emotional and
- challenges for Big Data, AI/ML, and enterprise knowledge-graphs.
Scalability, security, trust, APIs and vocabulary development:
- Techniques for mapping data between vocabularies with overlapping semantics, as a basis for scaling across different communities;
- digital signatures for RDF and Property graphs, e.g. to verify that the graph hasn’t been tampered with;
- what’s next for remote access to data and information services;
- how to make W3C a more attractive venue for work on vocabularies.
We aim to share experiences, use case studies, new directions and insights on what’s needed for the next generation of Web data standards.
For more information on the workshop, please see details and submission instructions, and further background information. Expression of Interest and position statements are due by 15 December 2018.
The Timed Text Working Group published the following specifications as W3C Proposed Recommendations:
The Timed Text Markup Language is a content type that represents timed text media for the purpose of interchange among authoring systems. TTML 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 1 November 2018.
The W3C SVG Working Group has published an updated Candidate Recommendation of Scalable Vector Graphics (SVG) 2. TThis specification defines the features and syntax for Scalable Vector Graphics (SVG) Version 2. SVG is a language based on XML for describing two-dimensional vector and mixed vector/raster graphics. SVG content is stylable, scalable to different display resolutions, and can be viewed stand-alone, mixed with HTML content, or embedded using XML namespaces within other XML languages. SVG also supports dynamic changes; script can be used to create interactive documents, and animations can be performed using declarative animation features or by using script.
The Accessible Rich Internet Applications Working Group has published WAI-ARIA Graphics Module 1.0 (Graphics-ARIA) and Graphics Accessibility API Mappings 1.0 (Graphics-AAM) as W3C Recommendations. Graphics-ARIA defines core roles specific to web graphics which allow an author to express the logical structure of the graphic to assistive technologies in order improve accessibility of graphics. Graphics-AAM defines how user agents map the WAI-ARIA Graphics Module markup to platform accessibility APIs. Assistive technologies could then enable semantic navigation and adapt styling and interactive features, to provide an optimal experience for the audience.

W3C announced today a W3C Workshop on Strong Authentication and Identity, December 10-11 2018, in Redmond, WA, USA. The event is hosted by Microsoft.
This workshop will look to provide an existing standards landscape, roadmap and potential future work for how strong identity and strong authentication should work on the web. A successful workshop will be how to align recent W3C specifications (WebAuthn, Verifiable Claims, Web Payments) and work that is ongoing in the W3C Credentials Community Group (DID, DIDAuth) along with IETF and ISO, as well as other existing community standards such as Open ID Connect, Oauth, SAML, etc.
The scope includes:
- Strong Authentication: FIDO, WebAuthn, IFAA, DIDAuth, OpenID Connect
- Strong Identity: ISO 29003, Entity Attestation Token (EAT)
- Decentralized Identity (DID): Blockchain / Distributed Ledger Technologies, Verifiable Credentials
- Federation: OpenID Connect, SAML, DID
- Credentials: Verifiable Credentials, JWT, JSON-LD, Entity Attestation Token (EAT)
- Requirements: Ease of Use, Accessibility, Internationalization, Security, Privacy
For more information on the workshop, please see details and submission instructions. Expression of Interest and position statements are due by 29 October 2018.
The Web Real-Time Communications Working Group invites implementations of two Candidate Recommendations:
- WebRTC 1.0: Real-time Communication Between Browsers: this document defines a set of ECMAScript APIs in WebIDL to allow media to be sent to and received from another browser or device implementing the appropriate set of real-time protocols.
- Identity for WebRTC 1.0: this document defines a set of ECMAScript APIs in WebIDL to allow and application using WebRTC to assert an identity, and to mark media streams as only viewable by another identity.
The Web Performance Working Group has published a First Public Working Draft of Device Memory. This document defines a HTTP Client Hint header to surface device capability for memory i.e. device RAM, in order to enable web apps to customize content depending on device memory constraints.
