Fowler provides a good overview of the business problem that requires a calendar [Fowler-Calendar]. A good starting point for our discussion is shown in the following Figure. <br/><br/>Note that here we are using the term Calendar rather than Schedule.<br/><br/>A Calendar has an owner who can control updates to it. The Calendar could also be associated with Assets like a Site or a Workgroup.<br/><br/>A Calendar contains Calendar Entries. These entries are related to events and have a temporal expression that indicates the Time Periods for the entry. Note that an entry may have repeating Time Periods in the temporal expression.<br/><br/>In the following Figure, the slashes on the associations denote that the association is derived. This is because the entities are logically associated, but the actual association is done via subclasses of the entities.<br/>
