 The architecture of the Urbiflock framework shown below is divided in three layers: applications, Urbiflock core, and Urbiflock infrastructure.
+{{ :uf:urbiflock_architecture.png?375x400 |:uf:urbiflock_architecture.png}}
+The application layer includes several core applications which are currently available in the framework such as flock and profile editors, and several users applications such as //I rate you// (IR8U), and //Guanotes//. The Urbiflock's core is composed of three main facilities specially designed to enable social interactivity and deal with the highly dynamic environment to which mobile devices exposes them: flockr, user profile and the TOTAM framework for flock communications.
-The application layer includes several core applications which are currently available in the framework such as flock and profile editors, and several users applications such as //I rate you// (IR8U) that allows users to ask proximate users to rate them on a certain subject, and //Guanotes//. The Urbiflock's core is composed of three main facilities specially designed to enable social interactivity and deal with the highly dynamic environment to which mobile devices exposes them: flockr, user profile and the TOTAM framework for flock communications.
 The infrastructure layer consists of three low-level abstractions on which the framework core is based: a RETE engine which orchestrates the flock composition, and the service discovery and communication APIs to discover and communicate with nearby applications, respectively.
-In the rest of this subsection we give a general overview of the relevant parts of the framework.
+In the rest of this subsection we list the relevant parts of the Urbiflock framework.
-  * [[uf:flockr|Flockr]]: a representation of the user in the framework
+  * [[uf:flockr|Flockr]]: A flockr represents a user in the framework.
-  * [[uf:profiles|Profile]]: manage user's profile and cache profiles of other flockrs
+  * [[uf:profiles|User Profile]]: Profiles in Urbiflock represent the user identity (e.g. name, gender, hobbies, etc.).
-  * [[uf:flock|Flock]]: a group of 'proximate' users
-  * [[uf:proximities|Proximities]]: "functions" that determine whether or not a user is proximate.
-    * isNearby: physical proximity
-    * isFriend: static encoding of friendship relationships
-    * doesProfileMatch: tests an attribute of a user's profile, form ATTR OP VAL, where ATTR is e.g. age, name, gender, hobbies, ...
-    * combinators: and, or, not
-  * [[uf:application|Application]]: define the API of an "application object"
-  * [[uf:applications|Applications]]: manage applications
-==== Applications ====
+  * [[uf:flock|Flock]]: a loosely defined group of users. It is an alternative representation of user groups specially designed to enable the dynamic interaction of social networks in pervasive social applications. A flock is defined in terms of a characteristic function.
-  * [[uf:viewer|Flock Viewer]]: a viewer and editor to view existing flocks and to create new flocks.
+  * [[uf:proximities|Characteristic Functions]]: "functions" that determine whether or not a user belongs to a Flock.
-  * [[uf:app_viewer|Application Viewer]]: a viewer and editor to view existing applications and install/delete them.
+  * [[uf:totam|TOTAM]]: tuple-based middleware for flock communication.
-  * [[uf:profile_viewer|Profile Viewer]]: a viewer and editor to view existing flockr profiles and to update your profile.
+  * [[uf:application|Applications]]: define the API of an "application object" to be plugged in the framework. What follows is the list of applications in Urbiflock.
-  * [[uf:iflocku|IFlockU]]: a friend suggestor based on profile similarity and time spent in proximity.
+    * [[uf:viewer|Flock Viewer]]: a viewer and editor to view existing flocks and to create new flocks.
-  * [[uf:guanotes|Guanotes]]: a messenger application that sends post-its to flocks.
+    * [[uf:app_viewer|Application Viewer]]: a viewer and editor to view existing applications and install/delete them.
-  * [[uf:ir8u|IR8U]]: an application that allows you to rate your friends.
+    * [[uf:profile_viewer|Profile Viewer]]: a viewer and editor to view existing flockr profiles and to update your profile.
+    * [[uf:iflocku|IFlockU]]: a friend suggestor based on profile similarity and time spent in proximity.
+    * [[uf:guanotes|Guanotes]]: a messenger application that sends post-its to flocks.
+    * [[uf:ir8u|IR8U]]: an application that allows users to ask proximate users to rate them on a certain subject.
