- | ==== Terminology ==== | + | Urbiflock is a Facebook-like application framework for mobile devices. As in Facebook, users that join Urbiflock can meet other users and interact with them. For example users may broadcast announcements to each other, they can browse one another’s profile, launch interactive polls, etc. The framework takes care of managing a user’s social networks, called “flocks”. A flock represents a loosely-defined group of users. A flock can be compared to a Facebook group (for example, a group of your old classmates), |
- | * Flock: a group of proximate users | + | Users can also build applications and plug them into the Urbiflock framework. Several core applications are currently available in the Urbiflock framework, such as flock creators and profile viewers. The framework also counts with two user applications //I rate you (IR8U)// that allows users to ask proximate users to rate them on a certain subject, and // |

- | An ad hoc RETE-network. Events are triggered by: | + | |
- | * discovery: '' | + | |

- | These events are received by the local flockr user object and propagated to all local proximities. Proximities translate these events into addUser / removeUser events | + | * [[uf:flockr|Flockr]]: A flockr represents a user in the framework. A flockr is also the gateway that other applications can use to get information about the user or about the applications that the user has installed. |
