Interface of activitypub objects + convenient functions.
Object types
type id = Rdf.Term.termAn id is an RDF term.
val gen_id : Iri.t -> Rdf.Term.term * Iri.tGenerate a new id, by appending to a given base IRI. For a same base IRI, Ids are guaranteed to be generated in increasing order when compared alphanumerically. The function returns both the id and the corresponding IRI, for conveniency.
class type collection = object ... endA Collection's interface.
class type collection_page = object ... endA CollectionPage's interface.
class type ordered_collection = object ... endAn OrderedCollection's interface.
class type ordered_collection_page = object ... endAn OrderedCollectionPage's interface.

val activity_types : (activity_type * Iri.t) listval activity_type_of_iri : Iri.t -> activity_type optionval iri_of_activity_type : activity_type -> Iri.tActor types
val actor_types : (actor_type * Iri.t) listval actor_type_of_iri : Iri.t -> actor_type optionval iri_of_actor_type : actor_type -> Iri.tConvenient functions
iri_of_lo (`L link) returns link#href. iri_of_lo (`O obj) returns obj#iri.
iri_of_liri (`L link) returns link#href. iri_of_liri (`I iri) returns iri.
iri_of_li (`L link) returns link#href. iri_of_li (`I image) returns the iri associated to image#id, or else the first iri of image#url.
val actor_name :
?lang:Smap.key ->
< name : string option
; name_map : string Smap.t
; preferred_username : string option.. > ->
stringactor_name a returns name of actor is present, or preferred_username if present, or "". Whe a lang argument is given, lookup for the name in then name language map of a.
object_content o returns content string of o if present, or "". If a lang argument is given, lookup in the content map of o.
Activity trees
This is a recursive representation of activities, since activities can refer to activities, themselves referring to other activities and so on.
It is sometimes useful to be able to pattern-match on activities on different depths.
type activity_obj = [ | `None| `Activity of activity_tree| `Actor of actor_type * object_| `Object of object_| `Loop of id
]and activity_tree = activity_type * activity * activity_objval activity_tree :
< object_ : object_ option ; type_ : Iri.t.. > as 'a ->
(activity_type * 'a * activity_obj) optionBuild an activity_tree from the given object and its internal graph. No dereferencing is performed to build the tree.
