Concepts
Discussion Context
A discussion context represent a context that can be linked to a discussion.
A discussion can have several discussion contexts and a discussion context can be linked to several discussions.
A discussion context is defined by its name, description and entity reference.
The name and description are here to describe the discussion context in natural language.
The entity reference represent the kind of entity referenced by the discussion context and is composed of an entity type and an entity reference.
entity The type represents the type of the referenced entity, and the entity reference stores a string that identified uniquely the referenced entity.
Each application that uses the discussions application to integrates discussions in its context can use its own type of entities.
For instance, in the context of the integration of the discussions in the ActivityPub Application, the discussion contexts are of type activitypub-activity and their values are the URIs of the references ActivityPub activities.
Discussion
A discussion contains a collection of message and can be linked to several discussion contexts.
Discussions are the queried by looking at the discussion context to which they are linked.
For instance, in the context of the integration of the discussions in the ActivityPub Application, the list of the discussions related to a given activity are found by querying the discussions that are linked to a discussion context with an entity reference type equals to activitypub-activity and an entity reference equals to the URI of the activity.
