Federated presence refers to sharing the status of an entity across the Fediverse. This is usually seen as a user becoming online/offline but could also be used to indicate something is active or available.

The Arrive and Leave activities are used to indicate when an entity is online or offline. The Place object with the url property is used to indicate where the entity can be found.


The following is an example sent from Immers Space when a user comes online.
