This proposal is a step towards splitting up Gewässerkennzahl (P1183) which does not represent a single identification system. --1-Byte (talk) 19:08, 19 July 2017 (UTC)[reply]

Comment how many of these are expected? Also I'm guessing there's no website we could point to to resolve these (formatter URL)? ArthurPSmith (talk) 17:26, 27 July 2017 (UTC)[reply]
- @ArthurPSmith: There are 620 entries which are already indexed and can be copied from Gewässerkennzahl (P1183). In total there are several thousand numbers assigned (most of which are probably not relevant though). I added a formatter URL to display some basic information about a number. 1-Byte (talk) 20:06, 27 July 2017 (UTC)[reply]
Support ok, looks good to me! ArthurPSmith (talk) 20:47, 27 July 2017 (UTC)[reply]
Support Add "CZ" in the name. And what a god-awful formatterURL that is! Bet it'll break in less than 2 years. But hopefully the Czech will maintain it --Vladimir Alexiev (talk) 18:01, 29 September 2017 (UTC)[reply]
