-- | The ActivityStreams Base Schema specification defines the
-- following core verbs in addition to the default post verb that is
-- defined in Section 6 of activitystreams:
data SchemaVerb
  = Accept
    -- ^ Indicates that that the actor has accepted the object.
    -- For instance, a person accepting an award, or accepting an assignment.
  | Access
    -- ^ Indicates that the actor has accessed the object. For
    -- instance, a person accessing a room, or accessing a file.
  | Acknowledge
    -- ^ Indicates that the actor has acknowledged the object.
    -- This effectively signals that the actor is aware of the
    -- object's existence.
  | Add
    -- ^ Indicates that the actor has added the object to the target.
    -- For instance, adding a photo to an album.
  | Agree
    -- ^ Indicates that the actor agrees with the object. For example,
    -- a person agreeing with an argument, or expressing agreement
    -- with a particular issue.
  | Append
    -- ^ Indicates that the actor has appended the object to the
    -- target. For instance, a person appending a new record
    -- to a database.
  | Approve
    -- ^ Indicates that the actor has approved the object. For
    -- instance, a manager might approve a travel request.
  | Archive
    -- ^ Indicates that the actor has archived the object.
  | Assign
    -- ^ Indicates that the actor has assigned the object to the target.
  | At
    -- ^ Indicates that the actor is currently located at the object.
    -- For instance, a person being at a specific physical location.
  | Attach
    -- ^ Indicates that the actor has attached the object to the
    -- target. For instance, a person attaching a file to a wiki
    -- page or an email.
  | Attend
    -- ^ Indicates that the actor has attended the object. For
    -- instance, a person attending a meeting.
  | Author
    -- ^ Indicates that the actor has authored the object. Note that
    -- this is a more specific form of the verb \"create\".
  | Authorize
    -- ^ Indicates that the actor has authorized the object. If
    -- a target is specified, it means that the authorization is specifically
    -- in regards to the target. For instance, a service can authorize a
    -- person to access a given application; in which case the actor is
    -- the service, the object is the person, and the target is the
    -- application. In contrast, a person can authorize a request; in
    -- which case the actor is the person and the object is the request
    -- and there might be no explicit target.
  | Borrow
    -- ^ Indicates that the actor has borrowed the object. If a target
    -- is specified, it identifies the entity from which the object was
    -- borrowed. For instance, if a person borrows a book from a library,
    -- the person is the actor, the book is the object and the library is
    -- the target.
  | Build
    -- ^ Indicates that the actor has built the object. For example, if a
    -- person builds a model or compiles code.
  | Cancel
    -- ^ Indicates that the actor has canceled the object. For instance,
    -- canceling a calendar event.
  | Close
    -- ^ Indicates that the actor has closed the object. For instance, the
    -- object could represent a ticket being tracked in an issue management
    -- system.
  | Complete
    -- ^ Indicates that the actor has completed the object.
  | Confirm
    -- ^ Indicates that the actor has confirmed or agrees with the object.
    -- For instance, a software developer might confirm an issue reported
    -- against a product.
  | Consume
    -- ^ Indicates that the actor has consumed the object. The specific
    -- meaning is dependent largely on the object's type. For instance,
    -- an actor may \"consume\" an audio object, indicating that the actor
    -- has listened to it; or an actor may \"consume\" a book, indicating
    -- that the book has been read. As such, the \"consume\" verb is a
    -- more generic form of other more specific verbs such as \"read\" and
    -- \"play\".
  | Checkin
    -- ^ Indicates that the actor has checked-in to the object. For
    -- instance, a person checking-in to a Place.
  | Create
    -- ^ Indicates that the actor has created the object.
  | Delete
    -- ^ Indicates that the actor has deleted the object. This implies,
    -- but does not require, the permanent destruction of the object.
  | Deliver
    -- ^ Indicates that the actor has delivered the object. For example,
    -- delivering a package.
  | Deny
    -- ^ Indicates that the actor has denied the object. For example, a
    -- manager may deny a travel request.
  | Disagree
    -- ^ Indicates that the actor disagrees with the object.
  | Dislike
    -- ^ Indicates that the actor dislikes the object. Note that the
    -- \"dislike\" verb is distinct from the \"unlike\" verb which assumes
    -- that the object had been previously \"liked\".
  | Experience
    -- ^ Indicates that the actor has experienced the object in some
    -- manner. Note that, depending on the specific object types used for
    -- both the actor and object, the meaning of this verb can overlap
    -- that of the \"consume\" and \"play\" verbs. For instance, a person
    -- might \"experience\" a movie; or \"play\" the movie; or \"consume\"
    -- the movie. The \"experience\" verb can be considered a more generic
    -- form of other more specific verbs as \"consume\", \"play\", \"watch\",
    -- \"listen\", and \"read\"
  | Favorite
    -- ^ Indicates that the actor marked the object as an item of special
    -- interest.
  | Find
    -- ^ Indicates that the actor has found the object.
  | FlagAsInappropriate
    -- ^ Indicates that the actor has flagged the object as being
    -- inappropriate for some reason. When using this verb, the context
    -- property can be used to provide additional detail about why the
    -- object has been flagged.
  | Follow
    -- ^ Indicates that the actor began following the activity of the
    -- object. In most cases, the objectType will be a \"person\", but it
    -- can potentially be of any type that can sensibly generate activity.
    -- Processors MAY ignore (silently drop) successive identical \"follow\"
    -- activities.
  | Give -- ^ Indicates that the actor is giving an object to the
    -- target. Examples include one person giving a badge object to another
    -- person. The object identifies the object being given. The target
    -- identifies the receiver.
  | Host
    -- ^ Indicates that the actor is hosting the object. As in hosting
    -- an event, or hosting a service.
  | Ignore
    -- ^ Indicates that the actor has ignored the object. For
    -- instance, this verb may be used when an actor has ignored a friend
    -- request, in which case the object may be the request-friend activity.
  | Insert
    -- ^ Indicates that the actor has inserted the object into the target.
  | Install
    -- ^ Indicates that the actor has installed the object, as in installing
    -- an application.
  | Interact
    -- ^ Indicates that the actor has interacted with the object. For
    -- instance, when one person interacts with another.
  | Invite
    -- ^ Indicates that the actor has invited the object, typically a
    -- person object, to join or participate in the object described
    -- by the target. The target could, for instance, be an event,
    -- group or a service.
  | Join
    -- ^ Indicates that the actor has become a member of the
    -- object. This specification only defines the meaning of this
    -- verb when the object of the Activity has an objectType of
    -- group, though implementors need to be prepared to handle other
    -- types of objects.
  | Leave
    -- ^ Indicates that the actor has left the object. For instance, a
    -- Person leaving a Group or checking-out of a Place.
  | Like
    -- ^ Indicates that the actor marked the object as an item of
    -- special interest. The \"like\" verb is considered to be an alias
    -- of \"favorite\". The two verb are semantically identical.
  | Listen
    -- ^ Indicates that the actor has listened to the object. This is
    -- typically only applicable for objects representing audio
    -- content, such as music, an audio-book, or a radio
    -- broadcast. The \"listen\" verb is a more specific form of the
    -- \"consume\", \"experience\" and \"play\" verbs.
  | Lose
    -- ^ Indicates that the actor has lost the object. For instance,
    -- if a person loses a game.
  | MakeFriend
    -- ^ Indicates the creation of a friendship that is reciprocated
    -- by the object. Since this verb implies an activity on the part
    -- of its object, processors MUST NOT accept activities with this
    -- verb unless they are able to verify through some external means
    -- that there is in fact a reciprocated connection. For example, a
    -- processor may have received a guarantee from a particular
    -- publisher that the publisher will only use this Verb in cases
    -- where a reciprocal relationship exists.
  | Open
    -- ^ Indicates that the actor has opened the object. For instance,
    -- the object could represent a ticket being tracked in an issue
    -- management system.
  | Play
    -- ^ Indicates that the actor spent some time enjoying the
    -- object. For example, if the object is a video this indicates
    -- that the subject watched all or part of the video. The \"play\"
    -- verb is a more specific form of the \"consume\" verb.
  | Post
    -- ^ The default action.
  | Present
    -- ^ Indicates that the actor has presented the object. For
    -- instance, when a person gives a presentation at a conference.
  | Purchase
    -- ^ Indicates that the actor has purchased the object. If a
    -- target is specified, in indicates the entity from which the
    -- object was purchased.
  | Qualify
    -- ^ Indicates that the actor has qualified for the object. If a
    -- target is specified, it indicates the context within which the
    -- qualification applies.
  | Read
    -- ^ Indicates that the actor read the object. This is typically
    -- only applicable for objects representing printed or written
    -- content, such as a book, a message or a comment. The \"read\"
    -- verb is a more specific form of the \"consume\", \"experience\" and
    -- \"play\" verbs.
  | Receive
    -- ^ Indicates that the actor is receiving an object. Examples
    -- include a person receiving a badge object. The object
    -- identifies the object being received.
  | Reject
    -- ^ Indicates that the actor has rejected the object.
  | Remove
    -- ^ Indicates that the actor has removed the object from the target.
  | RemoveFriend
    -- ^ Indicates that the actor has removed the object from the
    -- collection of friends.
  | Replace
    -- ^ Indicates that the actor has replaced the target with the object.
  | Request
    -- ^ Indicates that the actor has requested the object. If a
    -- target is specified, it indicates the entity from which the
    -- object is being requested.
  | RequestFriend
    -- ^ Indicates the creation of a friendship that has not yet been
    -- reciprocated by the object.
  | Resolve
    -- ^ Indicates that the actor has resolved the object. For
    -- instance, the object could represent a ticket being tracked in
    -- an issue management system.

    -- ^ Indicates that the actor has returned the object. If a target
    -- is specified, it indicates the entity to which the object was
    -- returned.
  | Retract
    -- ^ Indicates that the actor has retracted the object. For
    -- instance, if an actor wishes to retract a previously published
    -- activity, the object would be the previously published activity
    -- that is being retracted.
  | RsvpMaybe
    -- ^ The \"possible RSVP\" verb indicates that the actor has made a
    -- possible RSVP for the object. This specification only defines
    -- the meaning of this verb when its object is an event, though
    -- implementors need to be prepared to handle other object
    -- types. The use of this verb is only appropriate when the RSVP
    -- was created by an explicit action by the actor. It is not
    -- appropriate to use this verb when a user has been added as an
    -- attendee by an event organiser or administrator.
  | RsvpNo
    -- ^ The \"negative RSVP\" verb indicates that the actor has made a
    -- negative RSVP for the object. This specification only defines
    -- the meaning of this verb when its object is an event, though
    -- implementors need to be prepared to handle other object
    -- types. The use of this verb is only appropriate when the RSVP
    -- was created by an explicit action by the actor. It is not
    -- appropriate to use this verb when a user has been added as an
    -- attendee by an event organiser or administrator.
  | RsvpYes
    -- ^ The \"positive RSVP\" verb indicates that the actor has made a
    -- positive RSVP for an object. This specification only defines
    -- the meaning of this verb when its object is an event, though
    -- implementors need to be prepared to handle other object
    -- types. The use of this verb is only appropriate when the RSVP
    -- was created by an explicit action by the actor. It is not
    -- appropriate to use this verb when a user has been added as an
    -- attendee by an event organiser or administrator.
  | Satisfy
    -- ^ Indicates that the actor has satisfied the object. If a
    -- target is specified, it indicate the context within which the
    -- object was satisfied. For instance, if a person satisfies the
    -- requirements for a particular challenge, the person is the
    -- actor; the requirement is the object; and the challenge is the
    -- target.
  | Save
    -- ^ Indicates that the actor has called out the object as being
    -- of interest primarily to him- or herself. Though this action
    -- MAY be shared publicly, the implication is that the object has
    -- been saved primarily for the actor's own benefit rather than to
    -- show it to others as would be indicated by the \"share\" verb.
  | Schedule

    -- readers. In most cases, the actor did not create the object
    -- being shared, but is instead drawing attention to it.
  | Sponsor
    -- ^ Indicates that the actor has sponsored the object. If a
    -- target is specified, it indicates the context within which the
    -- sponsorship is offered. For instance, a company can sponsor an

    -- target. For example, if the actor specifies that a particular
    -- user appears in a photo. the object is the user and the target
    -- is the photo.
  | Terminate
    -- ^ Indicates that the actor has terminated the object.
  | Tie

    -- challenge is the target.
  | Unsave
    -- ^ Indicates that the actor has removed the object from the

-- | This data type contains the core set of common objectTypes in addition
-- to the "activity" objectType defined in Section 7 of
-- activitystreams.
--
-- All Activity Stream Objects inherit the same
-- fundamental set of basic properties as defined in section 3.4 of
-- activitystreams. In addition to these, objects of any specific type
-- are permitted to introduce additional optional or required
-- properties that are meaningful to objects of that type.
data SchemaObjectType
  = Alert
    -- ^ Represents any kind of significant notification.
  | Application
    -- ^ Represents any kind of software application.
  | Article
    -- ^ Represents objects such as news articles, knowledge base
    -- entries, or other similar construct. Such objects generally
    -- consist of paragraphs of text, in some cases incorporating
    -- embedded media such as photos and inline hyperlinks to other
    -- resources.
  | Audio
    -- ^ Represents audio content of any kind. Objects of this type
    -- MAY contain an additional property as specified
    -- <https://github.com/activitystreams/activity-schema/blob/master/activity-schema.md#audio-video here>.
  | Badge
    -- ^ Represents a badge or award granted to an object (typically a
    -- @person@ object)
  | Binary
    -- ^ Objects of this type are used to carry arbirary
    -- Base64-encoded binary data within an Activity Stream object. It
    -- is primarily intended to attach binary data to other types of
    -- objects through the use of the @attachments@ property. Objects
    -- of this type will contain the additional properties specified
    -- <https://github.com/activitystreams/activity-schema/blob/master/activity-schema.md#binary here>.
  | Bookmark
    -- ^ Represents a pointer to some URL -- typically a web page. In
    -- most cases, bookmarks are specific to a given user and contain
    -- metadata chosen by that user. Bookmark Objects are similar in
    -- principle to the concept of bookmarks or favorites in a web
    -- browser. A bookmark represents a pointer to the URL, not the
    -- URL or the associated resource itself. Objects of this type
    -- SHOULD contain an additional @targetUrl@ property whose value
    -- is a String containing the IRI of the target of the bookmark.
  | Collection
    -- ^ Represents a generic collection of objects of any type. This
    -- object type can be used, for instance, to represent a
    -- collection of files like a folder; a collection of photos like
    -- an album; and so forth. Objects of this type MAY contain an
    -- additional @objectTypes@ property whose value is an Array of
    -- Strings specifying the expected objectType of objects contained
    -- within the collection.
  | Comment
    -- ^ Represents a textual response to another object. Objects of
    -- this type MAY contain an additional @inReplyTo@ property whose
    -- value is an Array of one or more other Activity Stream Objects
    -- for which the object is to be considered a response.
  | Device
    -- ^ Represents a device of any type.
  | Event
    -- ^ Represents an event that occurs at a certain location during

    -- <https://github.com/activitystreams/activity-schema/blob/master/activity-schema.md#event here>.
  | File
    -- ^ Represents any form of document or file. Objects of this type
    -- MAY contain an additional @fileUrl@ property whose value a

    -- <https://github.com/activitystreams/activity-schema/blob/master/activity-schema.md#issue here>.
  | Job
    -- ^ Represents information about a job or a job posting.
  | Note
    -- ^ Represents a short-form text message. This object is intended
    -- primarily for use in "micro-blogging" scenarios and in systems
    -- where users are invited to publish short, often plain-text
    -- messages whose useful lifespan is generally shorter than that
    -- of an article of weblog entry. A note is similar in structure
    -- to an article, but typically does not have a title or distinct
    -- paragraphs and tends to be much shorter in length.
  | Offer
    -- ^ Represents an offer of any kind.
  | Organization
    -- ^ Represents an organization of any kind.
  | Page
    -- ^ Represents an area, typically a web page, that is
    -- representative of, and generally managed by a particular

    -- content such as articles, photographs and videos. Most social
    -- networking applications, for example, provide individual users
    -- with their own dedicated "profile" pages. Several allow similar
    -- types of pages to be created for commercial entities,
    -- organizations or events. While the specific details of how
    -- pages are implemented, their characteristics and use may vary,

    -- a single entity that is represented by the content provided by
    -- the page itself.

    -- <https://github.com/activitystreams/activity-schema/blob/master/activity-schema.md#place here>.
  | Process
    -- ^ Represents any form of process. For instance, a long-running
    -- task that is started and expected to continue operating for a
    -- period of time.
  | Product
    -- ^ Represents a commercial good or service. Objects of this type
    -- MAY contain an additional @fullImage@ property whose value is
    -- an Activity Streams Media Link to an image resource
    -- representative of the product.
  | Question
    -- ^ Represents a question or a poll. Objects of this type MAY
    -- contain an additional @options@ property whose value is an
    -- Array of possible answers to the question in the form of
    -- Activity Stream objects of any type.
  | Review
    -- ^ Represents a primarily prose-based commentary on another
    -- object. Objects of this type MAY contain a @rating@ property as
    -- specified
    -- <https://github.com/activitystreams/activity-schema/blob/master/activity-schema.md#rating-property here>.
  | Service
    -- ^ Represents any form of hosted or consumable service that
    -- performs some kind of work or benefit for other
    -- entities. Examples of such objects include websites,
    -- businesses, etc.

    -- ^ Represents an activity that has yet to be completed. Objects
    -- of this type can contain additional properties as specified
    -- here.
  | Team
    -- ^ Represents a team of any type.
  | Video
