// A policy URI is GoToSocial's internal representation of
// one ActivityPub URI for an Actor or a Collection of Actors,
// specific to the domain of enforcing interaction policies.
//
// A PolicyValue can be stored in the database either as one
// of the Value constants defined below (to save space), OR as
// a full-fledged ActivityPub URI.
//
// A PolicyValue should be translated to the canonical string
// value of the represented URI when federating an item, or
// from the canonical string value of the URI when receiving
// or retrieving an item.
//
// For example, if the PolicyValue `followers` was being
// federated outwards in an interaction policy attached to an
// item created by the actor `https://example.org/users/someone`,
// then it should be translated to their followers URI when sent,
// eg., `https://example.org/users/someone/followers`.
//
// Likewise, if GoToSocial receives an item with an interaction
// policy containing `https://example.org/users/someone/followers`,
// and the item was created by `https://example.org/users/someone`,
// then the followers URI would be converted to `followers`
// for internal storage.
