this might be hard with a physical map, but pretty straight forward with a logical map. Something like a list of categories that represent room co-ordinates. Then poulate and edit the content withing the categories.
Just thought of a novel way to do this graphically. There is a script Ive used as a graphical guest map on the world image. a user picks up an icon, drops it on a location and a small window opens to enter some details.
The point here, is that the world map is only an image could be anything including a graphical layout of your server room.
Ill check out the script and post back
Ok, the module is called globtrotter and you can see and downlaod it
