Volumes

[edit]

The ID's are published in four volumes. I noticed that some numerals are duplicate. Therefore I have added a initial letter to indicate the volume: N (Newfoundland and Labrador coast), A (Atlantic coast), I (inland waters) and P (Pacific coast). They are now in the regex as "possible", because I intend to first correct the existing values. After completion of that, I will make the initial letter a fixed part of the identifier.

I have just removed the optional part of the prefix, so now these will start to appear in the constraint violations report. I will try and help to fix these up. — Martin (MSGJ · talk) 21:15, 13 November 2021 (UTC)[reply]
@Lymantria: I think this is now complete! — Martin (MSGJ · talk) 21:52, 14 November 2021 (UTC)[reply]
