Change to regex

I have changed the "5" in the property constraint to a "6" because I found a working Who's Who link with 7 digits, 1 over the original limit. ミラP 22:12, 22 April 2020 (UTC)

And now I've found a working one with 8 digits, so I'm increasing it by another digit. ミラP 14:07, 23 April 2020 (UTC)

URL format

Hi, I added the DOI.org URL format and match pattern so that DifoolBot would catch them too. Used on ~750 items as reference URL (P854) (FYI: Difool). Samoasambia ✎ 11:51, 23 October 2024 (UTC)

Hi @Samoasambia, I changed it a bit to include URLs without the 'U' character, like this one. Using this query, I retrieved fewer items than your 750. This might be because I excluded references that already have the Who's Who UK ID (P4789) (example), and 'self' references for the P4789 identifier (example) Difool (talk) 01:13, 25 October 2024 (UTC)
