 ==== Flockr ====
-Each Flockr has :
+A flockr represents a user in the framework. A flockr has exactly one profile and can create and be registered to multiple flocks. In addition, a flockr can have multiple installed applications. A flockr is also the gateway that remote parties can use to get information about the user.
+Each Flockr contains following info :
   * [[Profile]]
-  * list of its [[Flock]]s where it is registered.
+  * list of its [[Flock|flock]]s where it is registered.
-  * list of its [[Flock]]s.
+    * Note: maybe it should be stored in the profile.
-  * list of its friends ([[Flockr]]s references) 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.
+  * list of its [[Flock|flock]]s.
+    * predefined [[Flock|flock]]s ( e.g. buddyList).
+    * user-defined [[Flock|flock]]s.
+  * list of [[Proximities]] that are registered for this Flockr.
+  * list of its [[Application|applications]].
+  * a map of usernames to far refs to connected flockrs.
+A Flockr has a local and remote interface. The remote interface is the entity that gets exported to the ambient.
+Profile won't get exported to the ambient but it has to proactively asked to the Flockr. This allows: 1) Remote Flockr does not need to ask the [[Profile]] again (if you rediscover the Flockr) if it didn't change and 2) allow the Flockr to decide who can actually see its [[Profile]].
+The remote interface receives 3 types events from the network (join, left and changeProfile) and notifies the local interface of the Flockr which notifies the necessary [[Proximities]] objects.
+The local interface contains also receives the events on changes on the buddyList.
+The buddyList is a list of its friends Flockrs. The editor for [[Flock|flock]]s will allow 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.
+  * xtof suggestion to implement this:
+    * Make "cached" object abstraction. It is just a proxy object which forwards to the online version when it's online, otherwise the catched version. Every update, replaces the cached version with a clone. In other words, keeps a cached object that gets updated when you are connected.
+    * This abstraction could be used for any list of Flockrs that need offline Profile visualization. Maybe useful also for applications.
+Other Comments:
+[[Flockr]] actually should be able to decide who can see him. How? maybe Profile?
