On the contrary, in my opinion the literal address is the proper link between the map and a POI database. Addresses were invented exactly for the purpose of identifying a physical location. If someone asks you where you live you give them your address.
I would also extend beyond postal addresses to use the ref tag too. The content of the ref tag should be the human name for an object, such as 314 for a room. An external database would also use these references, such as to give the location of a university class. (This might require us to improve the ref tags a little. We might want to allow for some additional tags to allow the ref to be more specific.)
