Delete

The Delete activity is used to indicate the deletion of objects in Communecter, such as Note, Event, Project, Badge.

Reference

Activity: Delete
Object: A Communecter object

Internal Logic

When Communecter receives a Delete activity, it processes the activity based on the type of object being deleted. This can include Note, Event, or Project, among others.

Example 1: Withdrawal from Project

In this example, Armel Wanes decides to withdraw his contribution from the “EcoSmart Homes Initiative” project. The target field specifies the URL of the project that is being deleted.

{
 "@context" : "https://www.w3.org/ns/activitystreams",
 "type" : "Delete",
 "object" : "https://instance.communecter.org/api/activitypub/users/u/Hajavololona",
 "id" : "https://communecter.org/api/activitypub/activity/id/649caf628366d",
 "actor" : "https://communecter.org/api/activitypub/users/u/ArmelWanes",
 "target" : "https://communecter.org/api/activitypub/object/id/649c9e7ae4135",
 "published" : "2023-06-28T22:08:34+0000",
 "to" : [
 "https://www.w3.org/ns/activitystreams#Public"
 ],
 "cc" : [
 "https://instance.communecter.org/api/activitypub/users/u/Hajavololona"
 ]
}

Example 2: Simple Deletion

In this example, an object (such as a Note, Event, or Project) is deleted without any additional details.

{
 "@context" : "https://www.w3.org/ns/activitystreams",
 "type" : "Delete",
 "object" : "https://communecter.org/api/activitypub/object/id/6260f515bd856",
 "id" : "https://communecter.org/api/activitypub/activity/id/6260f54e8e2c5",
 "actor" : "https://communecter.org/api/activitypub/users/u/ArmelWanes",
 "published" : "2023-04-21T06:10:22+0000",
 "to" : [
 "https://www.w3.org/ns/activitystreams#Public"
 ],
 "cc" : [
 "https://instance.communecter.org/api/activitypub/users/u/yorre"
 ]
}

In both examples, the summary field provides a brief description of the deletion, such as “Armel Wanes has decided to withdraw his contribution from the ‘EcoSmart Homes Initiative’ project” or “Object has been deleted”. This gives an overview of the deletion activity.

In the summary field, you can specify a description of the deletion action. For example, “Armel Wanes has decided to withdraw his contribution from the ‘EcoSmart Homes Initiative’ project” or simply “Object has been deleted”. This provides a summary of the deletion activity.

Delete

The Delete activity can be used to remove an organization:

Example:

{
 "@context": "https://www.w3.org/ns/activitystreams",
 "type": "Delete",
 "actor": "https://communecter.org/api/activitypub/users/u/AdminUser",
 "object": "https://communecter.org/api/activitypub/groups/g/DissolvedOrg"
}

Delete

The Delete activity is used to remove objects from Funkwhale’s database.

Reference
Activity	Undo
Object	A Funkwhale `Library` or `Audio` object

Internal logic

When Funkwhale receives a Delete activity, it deletes the associated object from the database.

Funkwhale ensures the actor initiating the activity is the owner of the associated object before handling it.

Example

In this example, Bob deletes a library and notifies its followers.

{
 "@context": [
 "https://www.w3.org/ns/activitystreams",
 "https://w3id.org/security/v1",
 {}
 ],
 "type": "Delete",
 "to": [
 "https://awesome.music/federation/music/libraries/dc702491-f6ce-441b-9da0-cecbed08bcc6/followers"
 ],
 "actor": "https://awesome.music/federation/actors/Bob",
 "object": {
 "type": "Library",
 "id": "https://awesome.music/federation/music/libraries/dc702491-f6ce-441b-9da0-cecbed08bcc6"
 }
}

In this example, Bob deletes three audio objects in a library and notifies the library’s followers.

{
 "@context": [
 "https://www.w3.org/ns/activitystreams",
 "https://w3id.org/security/v1",
 {}
 ],
 "type": "Delete",
 "to": [
 "https://awesome.music/federation/music/libraries/dc702491-f6ce-441b-9da0-cecbed08bcc6/followers"
 ],
 "actor": "https://awesome.music/federation/actors/Bob",
 "object": {
 "type": "Audio",
 "id": [
 "https://awesome.music/federation/music/uploads/19420073-3572-48a9-8c6c-b385ee1b7905",
