Why is this relevant to Community Equity ? Well – to calculate the social value of a content object, person, community or tag we need to capture all activities of a person on whatever site the activity happens. Activity Streams seems to be a perfect fit.

The article below explains the concept of the activity streams standard and provides a mapping between the activity streams verbs and the Community Equity activities.

List of Basic Activities (enclosed sections have been co-authored by Josef Holy and Max Wegmüller)

All activities are described with a user, a verb and object.
Applications implementing this standard, needs to map there specific activities to the verbs and objects defined through Activity Streams.

Let’s start with a listing of basic (general) set of activities which users perform on some Content Object (CO), in the context of the Social Web. Content object can be literally anything – document, file, another user, community etc. Simply put – on the Web, content objects correspond to resources and are identified by URLs (persistent identifiers, which can be accessed and their representation retrieved via HTTP).

The following table contains a very basic list of activities, which can occur between basic entities of the Social Web – People, Content and Groups. These entities and their relationships form a mesh, where people, groups and content are interconnected. Cross-application distribution of activities then means notifying of changes done trough this mesh.
