Our system is targeted toward the English-speaking, non-technical population with special emphasis on three user groups: students, businesspeople, and families. Although our different user groups have varying levels of technical competence, we will gear our application toward people who have basic web experience.
Businesspeople: Businesspeople, who are between 20 and 70 years old, need calendars to keep track of their own schedules and those of their employees, clients, and colleagues.
Students: Students, who are between 14 and 22 years old, would use a calendar to organize class, homework, employment, and extra-curricular schedules.
...
Families: Families have a lot of tasks that need to be done, but that don't necessarily have deadlines. They currently make paper todo lists. A mother we spoke to wished that her current calendar system would allow her to jot down a todo list, just as she might scribble notes in the margin of her physical calendar.

Domain analysis
By default, events that users create are put in the "My Calendar" category. "My Calendar" is analogous to the root of a filesystem. We can create sub-categories, such as "My Extracurriculars", which in turn can have events or another sub-category, such as "Choir Rehearsals".
A category can have multiple parents. For example, "Choir Rehearsals" can belong to the "My Calendar" category as well as to the "Your Calendar" category. When I share my calendar with another user, I am really sharing one or more of the categories that are associated with the "My Calendar" category.
