Timetabling RIA in action

We present an Rich Internet Application to create timetabling for real engineering school. In this application, we have resources and constraints. Resources describe the timetable’s context. Constraints are restrictions of resources. All lectures are placed on a timetable composed of time-slots. For timetabling, we use a computational web service written in Prolog. Our application presents two different views, one for the user, and one for the admin. Users can view all generated timetables and put in their own constraints. The input of constraints can be done by two ways, directly from our application, or via Google calendar. To use Google calendar, users have to update the link of their Google calendar. Admin has many tasks to do. He has to plan all different lectures that occur in a year. He also has to specify which contributors teach which lecture, and to whom the lecture is being given. Moreover, he has to input constraints for classes, and possibly rooms’ unavailability. Then he has to validate or invalidate users constraints. Finally he can generate one or more timetables. He can also export all generated timetables to Google calendar.
