follow	follow	Activity Schema	Indicates that the actor began following the activity of the object. In most cases, the object 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	give	Activity Schema	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.
ignore	ignore	Activity Schema	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.
invite	invite	Activity Schema	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	join	Activity Schema	Indicates that the actor has become a member of the object. This specification only defines the meaning of this verb when its object is a group, though implementors SHOULD be prepared to handle other Object types a meaning MAY be provided by extension specifications.

leave	leave	Activity Schema	Indicates that the actor has left the object. For instance a Person leaving a Group or checking-out of a Place.
like	like	Activity Schema	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.
make-friend	make-friend	Activity Schema	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.
play	play	Activity Schema	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.

It is not appropriate to use this verb when a user has been added as an attendee by an event organiser or administrator.
rsvp-no	rsvp-no	Activity Schema	The "negative RSVP" verb indicates that the actor has made a negative RSVP for the object.

save	save	Activity Schema	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.

update	update	Activity Schema	The "update" verb indicates that the actor has modified the object.
