First Principles

[probablyangg]

• The interaction starts with a Community
• Each Community can have one or many Calendars
• Community is accessible via subdir (/<COMMUNITY>/rsvp/..., /<COMMUNITY>/all, /<COMMUNITY>/archive, etc.)
• The atomic unit of the application is a single User
• A User can create one or more Events
• Each Event is associated with one and only one Calendar
• An Event can be associated (or created by) more than one Users
• Every event is uniquely identified by its 'hash' (/rsvp/<HASH>)
• A user is not directly associated with a Community but can be associated indirectly if they have proposed an event that is part of a community's calendar or they have RSVP'd to an event that is part of a community's calendar
