The Invite activity is used to invite an actor to participate in a project or activity.

Internal Logic

When an actor wants to invite another actor to participate in an activity, they can send an Invite activity. The Invite activity includes the specific activity object being invited to.

Instrument Field

The instrument field can be used to provide additional context about the invitation. It specifies the role or type of participation the actor is being invited for. Some examples include:

“instrument”: “contributor”: Invites the actor to contribute to the activity.
“instrument”: “adminandrole”: Invites the actor to become an admin with specific roles in the project.
“instrument”: “admin”: Invites the actor to become an administrator of the activity.

NB: Please note that the use of the instrument field is optional and depends on the specific context of the invitation. For events, it is not necessary to include the instrument field.

}

Invitation with instrument (for project)

Inviting an Actor to Contribute

Inviting an Actor to Admin without Roles

In this example, Yorre invites Armel Wanes to become an admin without specifying additional roles in a project:

{
 "@context": "https://www.w3.org/ns/activitystreams",
 "type": "Invite",
 "object": "https://communecter.org/api/activitypub/users/u/ArmelWanes",
 "id": "https://communecter.org/api/activitypub/activity/id/649caf628366d",
 "actor": "https://communecter.org/api/activitypub/users/u/yorre",
 "instrument": "admin",
 "target": "https://communecter.org/api/activitypub/activity/id/649d514eba30c"
}

The Invite activity can be used to invite users to join an organization:

Example:

{
 "@context": "https://www.w3.org/ns/activitystreams",
 "type": "Invite",
 "actor": "https://communecter.org/api/activitypub/users/u/OrgAdmin",
 "object": "https://communecter.org/api/activitypub/users/u/PotentialMember",
 "target": "https://communecter.org/api/activitypub/groups/g/EcoFriendlyOrg"
}
