Designing an Activity Stream? Yeah, Thereâs a W3C Spec For That
Blog post from Stream
Activity streams, commonly found in modern applications, are challenging to build due to scalability and design complexities, yet resources often focus on infrastructure and publishing methods. Stream, a company addressing scalability issues, highlights the importance of designing serialized data for activity streams. The development of the Activity Streams Specification began in 2008 with the Atom format and evolved to JSON Activity Streams, with the W3C eventually overseeing the 2.0 specification. Activity Streams 1.0 defines an activity as consisting of an actor, verb, object, and target, and the 2.0 version enhances this with a standard vocabulary and extended features like audience targeting, allowing for user notifications through properties such as "to" and "Mention." The W3C's ongoing efforts have enriched the specification with multi-language support and JSON-LD compatibility, aiding developers in creating efficient, machine-processable activity streams.
