Within organizations and between organizations it is beneficial to be able to exchange plans and schedules. These may be at a high level where they deal with the tasks of work breakdown structure or at low and detailed level where they coordinate individual workers. This module captures information concerning schedules, resource allocation and leveling. This information is needed to manage the life cycle process of developing and using a system such that persons and organizations can coordinate their activities.

From the perspective of information cross coupling; the type extend lists identify within this module specify how all schedule information modelling concepts defined within the schemas of the schedule domain are coupled together via type extends within the schedule domain.
