Calendar data can be extracted from a scheduling application such as Microsoft Outlook. The data includes the working hours and the so-called free-busy information appearing in the calendar of a user. The free-busy information indicates a contiguous time period in which various blocks show the user has an event or a task scheduled, tentatively scheduled or not scheduled. In UCC API, the calendar data is represented by an instance of the calendarData category, which is encapsulated by this interface.An application can then query this interface from the corresponding IUccCategoryInstance object.
