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": [

    }
  ],
