The Maps & Layouts section has been organized into three different tiers of location data. Venues are the first tier and don’t require either of the other tiers to be established. A convention center or hotel may be an example of a Venue. The second tier is a Venue Location which is a space within a Venue. An example of a Venue Location may be a lobby or 2nd floor. A Venue Location narrows down where within the Venue a place exists and should be tied to the Venue upon creation. A Room is the third tier and is a space within a Venue Location within a Venue. A Room should be tied to both the Venue and Venue Location upon creation.
Any agenda event can be associated (or linked) to any location tier.
