A topographic location, generally having definite boundaries and with a finer detail than a geographic area. This concept is enough to represent the state of 'being at an address'. The relation for 'having an address' is a more complex issue, since having an address does not imply being at that address all the time (or a default amount of time). Instead having an address implies a social and legal responsibility for being retrievable, receiving mail, being contacted, having own estates localized, etc.
