Ambient-Oriented Programming

When creating a new flock, urbiflock crashes when trying to add a matching profile constraint on birthdates in conjunction with a < or > operator.

The flock editor should enforce that all flock names end with the “Flock” suffix.

We should add support for 'group flocks' which are a conjunction of the NearbyFlock and have a matching profile constraint of the form “group IS-IN user.profile.groups”
