The Social Web Working Group invites implementation of two Candidate Recommendations:
- Activity Streams 2.0: This specification details a model for representing potential and completed activities using the JSON format. In the most basic sense, an “Activity” is a semantic description of an action. It is the goal of this specification to provide a JSON-based syntax that is sufficient to express metadata about activities in a rich, human-friendly but machine-processable and extensible manner.
- Activity Vocabulary: This specification describes the Activity vocabulary. The Activity Streams 2.0 Vocabulary defines a set of abstract types and properties that describe past, present and future Activities.
