Notification types

• Notifications are defined as types in the same way that things and observations are.
• A notification type contains well-known supported properties, such as subject and body.
• Notifications types can be used in actor's policies to define access to the instances of the notifications types
• Instances of a notification type can be generated using an action notify in a reasoner

Validation for publication

In order to be published, an activity must be a valid json resource according to its metadata. All resources contained in the activity must also be valid for their metadata. The follower specific validations are also performed on the activity (some generate warning, others generate errors that will not allow publication)

• Types involved in reasoners, observers and actors must be published
  • If there is an unpublished type that is used, and it is owned by the activity owner, a warning is generated
  • If the unpublished type is owned by another user, an error is generated
• Types used in actors are involved in reasoners or observers (if not, a warning is generated)
• Actors must not contain policies for notifications of a different activity
