Public addressing

Public addressing is discussed here. The essential point here is that Public, as:Public, and https://www.w3.org/ns/activitystreams#Public are equivalent as JSON-LD and thus should be treated in the same way by Fediverse applications.

Examples

Example 1

activity
{
  "@context": [
    "https://www.w3.org/ns/activitystreams",
    {
      "Hashtag": "as:Hashtag",

    }
  ],
  "type": "Create",
  "actor": "http://pasture-one-actor/actor",
