The proposed @w3c Social Web #WorkingGroup charter focuses on maintaining and updating key social Web standards, such as #ActivityPub, Activity Streams, WebSub, Activity Vocabulary, MicroPub, Linked Data Notifications and Webmention, taking up from the maintenance and incubation work conducted in the Social Web Incubator #CommunityGroup.

📢 #w3cTPAC demo!
Web Video Map Tracks (#WebVMT), developed by the Spatio-temporal Data on the Web #WorkingGroup, is an open format designed to synchronize location with video for the web. This demo uses roadside video footage with GeoPose to analyse traffic using WebVMT in a web browser, including vehicle tracking, data synchronization with video, multi-device data aggregation, wrong-way traffic identification and forensic speed calculation.

#w3cTPAC group update!
Hongchan Choi, co-chair of the @w3c Audio #WorkingGroup, shares 2025 updates.
The Web Speech #API moved from WICG, with Chrome shipping and Firefox starting implementation, focusing on on-device recognition and #privacy. The Web Audio #API added the AudioContext interrupted state, now in a Chromium Origin Trial. The group also began work on a Playout Statistics API and continued collaborating on high-resolution time in worklets.

📢 #w3cTPAC demo!
Navigation capturing in Progressive Web Apps (#PWAs) boots performance by eliminating the delay associated with opening a new browser tab and loading a page. This results in a faster and smoother user experience, like in Google Chat, which cut latency by keeping navigation within the app for a more native, seamless feel.
