Collections are sets of components selected for courses (each course consists of 1-240 components) One collection may consist of only one teacher and one room, whereas another collection may be a long list of students plus their teachers, rooms and subjects. When the collection for a course is selected, each of its components shares the same schedule for that course. When a lecture of a course is assigned in the timetable, the timetables of all components are assigned simultaneously. The maximum number of components in each collection is 240.

Collections have a varied structure depending on the course type or institution. Some collections may contain one teacher, room and class/group, whereas some other may contain one teacher, two groups and two rooms. When creating personalised timetables, it is typical that collections contain one teacher, one room and several students.
It is possible to solve the same scheduling problem with different set of courses and their collections. The structures of the collections are not limited to some template in order to enable using Mimosa in very kinds of environments. For instance, the application can be used (and has used) to schedule conferences by assigning a course for each session and constructing the collections of one or more contributors, referee, room and translator.
When scheduling the rehearsals of an orchestra or theater performance, users normally create collections from participants and room of each session.
You can edit collections in Components view or in Courses view.
