Considering creating an item and using qualifier statement is subject of (P805)

If one is tempted to include much information with qualifiers, it may be preferable to make an item about the resource and link that with the above qualifier. --- Jura 18:22, 25 May 2021 (UTC)

Use of qualifier applies to part (P518)

Do we need this qualifier? The sample would be better handled by adding the property directly to Oregon Health & Science University Marquam Hill Campus (Q106963493). --- Jura 18:22, 25 May 2021 (UTC)

Cleared up problematic scoping

I am not sure how significant these changes might be received, but I modified the constraints for this property as I think they rely on assumptions about where an official map URL can be linked that don't always bear out.

I have expanded the scope of the property to be allowed as a qualifier. There may be a linkable map for something which does not meet the notability requirements to have a data item for which this could be used as a qualifier. It also depends on what the map is official to - multiple official maps can exist of the same entity if it is the official map for an organization operating within that entity. Seeing as there were constraint exceptions manually added for things like transit agencies and parks & recreation departments, it seems like people have already been running into this stumbling block when trying to link an official map to an organization or official designation rather than a place.

I removed the constraint requiring a country. The scope of maps extends beyond countries; an official map could depict locations in the ocean, on Antarctica, another planet, etc.

I also removed the constraint requiring the item to have a coordinate location, and allowed for coordinate locations to be used as a qualifier on the map URL instead. If the item is a geographic entity like a city, country, etc. it will likely already have related coordinate requirements because of that classification. However, there are entities which don't have locations themselves which may have official maps. For example, Q111902602 describes a statistical designation, not an instance of a location, and links to an official map of places that have that designation. It makes more sense to place coordinates as a qualifier on the map here as the designation itself is not something located somewhere, but the map is centered on a location.

Hopefully these changes make sense. --Middle river exports (talk) 20:57, 7 May 2022 (UTC)
