The format is built around composable descriptions of discreet actions being carried out by various kinds of actors. For instance, the format can describe actions such as “Sally uploaded a photo and shared it with her colleagues John and Mary” or “John invited Mary to join the Project Workgroup”. Because these descriptions are encoded in JSON they can be easily stored in a NoSQL database such as IBM Cloudant. And because the format is built around the principles of linked data with a highly structured and openly extensible data model, applications can easily perform a variety of analytics and workflow operations that enable deep insight into how users are engaging with an app.
Activity Streams Version 2.0 is currently under development by the W3C Social Web Working Group and is on track to become a W3C Candidate Recommendation. IBM is leading the effort in terms of co-chairing the working group, driving the design of the data model, and providing open source implementations.

Why should I contribute?
Standards such as Activity Streams thrive when they are tailored to the needs of real-world application requirements. This standard model has been contributed by an IBM Open Tech developer to the W3C Social Web Working Group.
Individuals can contribute to this important standard by participating in the Social Web Working Group discussions and bringing their use cases into the conversation. Developers can also contribute to new or existing open source implementations on GitHub that help grow the ecosystem of tools available.
What technology problem will I help solve?
Activity Streams provides consistency in the way applications describe action throughout a lifecycle of an application’s workflow, at every layer within the application and even across organizational boundaries. The standard provides a common vocabulary and processing model that makes it easier to analyze and understand how users are engaging with your application and with other users.
