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. 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. This can include constructing natural-language descriptions or visual representations about the activity, associating actionable information with various types of objects, communicating or recording activity logs, or delegation of potential actions to other applications.
- Activity Vocabulary: The Activity Streams 2.0 Vocabulary defines a set of abstract classes and properties that describe past, present and future Activities. This document defines the Activity vocabulary and its properties.
