Hi, list I'm working on expressing Japanese address structure. Also, revising "place" structure.
We JP had collected samples, and made a structure from them. Please tell us your comments. (I'm preparing wiki page editing) https://docs.google.com/spreadsheet/ccc?key=0ApY7X6fw8sqxdDNjY1FBeG00TlRZSFoxU2xwOHVCb0E#gid=1 * Block addressing System In general "Block Address System" structure, it could be compatible between "addr:street" and "addr:blocknumber". It is simple :) * JP Situation JP address system are very messy. Since it is a mixture of general "Block Number System" and "from Old Cadestra System". Some local governments treats Cadestra as Address representation. So, many many exceptions are there. But IMHO, the whole structural order is simple. * Key proposal addr:blocknumber subprovince (as "place" structure) Using "quarter" (as "place" and "addr:quarter" structure) * Challanges 1. Using key "quarter" I understand that "place=quarter" is under proposal, and non-recommended key. Please tell me if there are some another choice. http://wiki.openstreetmap.org/wiki/Proposed_features/place%3Dquarter In Japan, neighbourhood is divided "upper" and "lower". So I use "quarter" as represent "Upper Neighbourhood". Should we use another word to represent "Upper Neighbourhood"? (e.g. "neighbourhood" and "subneighbourhood" come to mind) "Upper" and "Lower" are very separated ones, so they are difficult to merge as one "neighbourhood", I think. 2. subprovince We would like to use it as structural order. 3. addr:housenumber may contain "NULL" In some case, "addr:housenumber" contain "NULL". (in fact, it seems as 1 or 1-1. But numbers are vanished, even in public description) Is it permissive? * reference pages http://wiki.openstreetmap.org/wiki/Key:place http://wiki.openstreetmap.org/wiki/Key:addr Regards. -- Satoshi IIDA mail: nyamp...@gmail.com twitter: @nyampire
