Why not treat any word that begins with a digit as house number? Note that street names sometimes contain numbers, although I think I've only seen them using roman numerals, like "Via IV Novembre" here in Italy. Another situation could be a year as part of the street name. I've never seen such a street name, but it could be possible. I suggest an algorithm similar to this: 1) any "word" that begins with a digit is defined to be a "number" (including "17B", "32/C" and such) 2) if a number is at the beginning or the end of the street name *and* is separated using "," then it is the street number (eg. "Via Roma, 36C" or "38, Sesame Street") 3) if there is a number ar the beginning or the end without a "," then it is still the street number 2 and 3 may seem identical, but 2 has higher precedence, so that a string like "34, Via Tirol 1809" still gets recognized correctly. Just a quick idea.. :-) Udo _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
