Ambient-Oriented Programming

Profiles: each Flockr has a Profile. There is a minimal set of properties that are present in each Profile (such that Proximities (e.g. a “doesProfileMatch” Proximity) can be defined based on these properties).

Changed events: when a Flockr modifies his Profile, a change event is propagated to the remote interfaces of all other Flockrs. In reaction to these events, all connected Flockrs propagate these events to the interested Proximities.

Caching: Each Flockr keeps a cached Profile of the other Flockrs such that the Profile can be consulted offline. When a Flockr is connected for which there is a cached Profile, he should propagate the necessary changed events to make sure that both the cached Profile and the Flocks of the other Flockrs are updated.

Profile:

Flockr - Remote Interface: profileChangedOf(flockrRef)

Flockr - Local Interface: getUpdatedProfile(flockrRef)

Proximity: profileChanged(profile, flockrRef)

CachedProfile: profileChanged(profile, flockrRef)
