Suppose we want to have a project meeting in which participants take turns to draw on the whiteboard. We should somehow put together the above specified two collaboration types. In Figure 6, the collaboration we want, projmeeting, extends collaborations meeting and fc. Only two roles are available here. The project manager is composed from the floor moderator and the drawer. And the normal project member is a composition of the aspirant and the drawer. So the manager controls the floor. Participants in both roles are free to draw on the whiteboard once they become the floor holder. Roles inherited, e.g. drawer, moderator, aspirant, and the floor holder are made invisible to participants of the collaborative sessions created out of this collaboration.
