The mission of the Pointer Events Working Group is to provide methods to enable simple device independent input from pointing devices such as mouse, pen, and multi-touch screen.
The mission of the PNG Working Group is to maintain and develop the Portable Network Graphics (PNG) specification.
The mission of the RDF Dataset Canonicalization and Hash Working Group is to define a standard to uniquely and deterministically calculate a hash of RDF Datasets for use cases such as Detecting changes in Datasets. The work will include defining RDF Dataset Canonicalization algorithms.
- Data and knowledge
The mission of the Service Workers Working Group is to enable Web applications to take advantage of persistent background processing, including hooks to enable bootstrapping of web applications while offline.
The mission of the Spatial Data on the Web Working Group is to: 1) develop and maintain vocabularies and best practices that encourage better sharing of spatial data on the Web; 2) identify areas where standards should be developed jointly by both W3C and the Open Geospatial Consortium (OGC).
The mission of the Scalable Vector Graphics (SVG) Working Group is to develop and maintain SVG.
The mission of the Timed Text Working Group is to develop W3C Recommendations for media online captioning by developing and maintaining new versions of the Timed Text Markup Language (TTML) and WebVTT (Web Video Text Tracks) based on implementation experience and interoperability feedback, and the creation of semantic mappings between those languages.
- Media & Entertainment
The mission of the Verifiable Credentials Working Group is to maintain the Verifiable Credentials Data Model specification and related Working Group Notes.
