Heritage designation

Only a subset of Canmore records are for listed / scheduled buildings. Most are not. I've removed the unhelpful constraint requiring a heritage designation for a Canmore ID'd item. --Tagishsimon (talk) 09:16, 27 November 2019 (UTC)

Removal of two constraints

The single best value constraint has gone; it is inappropriate to suggest users elect a single best value, for items that have multiple P718s. (Example: scheduled monument with many components each having distinct Canmore IDs.) Risk that so-doing removed valid Canmore IDs from wdt:P718 reports.

The 'needs commons category' constraint also gone. It's aspirational at best; only ~3% of items with Canmore ID have commons cats. Images for many Canmore records, being part of a larger whole (e.g. the Scheduled Monument with many components) are most unlikely to get a category since they will instead be categorised under the Scheduled Monument's category. --Tagishsimon (talk) 22:34, 4 January 2020 (UTC)

I also removed "Scotland (Q22)" from item-requires-statement constraint (Q21503247) located in the administrative territorial entity (P131) Scotland (Q22), as system checks for strict equality (instead of checking hierarchy) and produces 63308 violations. --Lockal (talk) 07:51, 2 September 2020 (UTC)

Anomalies, issues, and corrections

• Glasgow, Cowlairs Incline, Railway Tunnel (Q114077095) : Canmore 103559 and 300833 are duplicates. Jheald (talk) 17:31, 2 October 2022 (UTC)
• Glasgow, St Vincent Terrace Railway Tunnel (Q114077169) : Canmore 277497 NGR reference is mis-keyed (should be 6573 not 6537), and maps appear to show the road crossed as "St Vincent's Crescent" rather than "St Vincent's Terrace" Jheald (talk) 18:25, 2 October 2022 (UTC)
