The Timed Text Working Group published the following specifications as W3C Proposed Recommendations:

• Timed Text Markup Language 1 (TTML1) (Third Edition)
• Timed Text Markup Language 2 (TTML2)
• TTML Profiles for Internet Media Subtitles and Captions 1.1

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.
