To +1 the other messages in this thread: We had a long discussion in GEOPRIV about this (I've been involved in the DHCP civic draft, which yielded the 4119 elements). Civic addressing *seems* easy until you delve into the amazing variations that are used around the world. Just relying on intuition about US postal addresses is a likely road to quick obsolescence. (There's even more elaborate work going on in specialized GIS and postal standardization bodies [Universal Postal Union], but they are likely to be too unwieldy or inaccesible for non- specialists.) The draft should also explicitly reference the various profiles that either have already been specified or will be specified, e.g., for Austria. The whole point of this exercise is to have semantically- marked data, as we can otherwise just carry a text string formatted in whichever way somebody feels like.
