The application/stream+json Media Type

Activity Streams is a data format for "the serialization of a stream of social activities using the JSON format" . Version 1.0 of the specification was published in May of 2011 by the Activity Streams Working Group () and has been implemented in a broad range of applications. This specification defines and registers the "application/stream+json" Content Type to represent JSON document resources that conform to the JSON Activity Streams Version 1.0 Specification.

Security considerations: As defined in this specification Published specification: This specification. Applications that use this media type: JSON Activity Streams are implemented by a wide range of existing applications.
