Re: this change:

quantity (P1114) has a constraint that it should not have a unit. However, applying it meaningfully to material used (P186) statements requires that it does have a unit, which leads to lots of violations: . I see a few ways to handle this, and I'd like your thoughts:

1. Simply remove the constraint from quantity (P1114), and allow it to be used with units everywhere (I imagine there will be some pushback on that, but it seems reasonable to me).
2. Create a custom constraint for quantity (P1114), so that the "no units" constraint is not applied when the parent item is a cocktail, or certain other specific classes of items (but which classes?)
3. Propose a new property to replace quantity (P1114) for these uses. A fair amount of work, but it would preserve the unitlessness that quantity (P1114) purists may want.

Cocktails can use volume as quantity (P2234) instead of quantity (P1114) like I changed it to on Long Island Iced Tea (Q1052769). Also things like bicycle (Q11442) has 2 wheels which is fine for the quantity property. Also material used (P186) has proportion (P1107) as possible statement which might be helpful in a lot of use cases instead of quantity. Receipies for example will be scaled to the use case anyway I think? 2 people, 4 people, 100 people, … Then proportion (P1107) might be more accurate than quantity (P1114) is?

Would you mind working to replace quantity (P1114) with volume as quantity (P2234) on cocktails as you suggest? This query should be a pretty complete list.

The other main use cases seem to be:

• Adhesives, with units of kilogram or mass fraction
• Works of art, which don't seem to have units (not sure how to get the query to show only those that do)
• The rest, a random assortment e.g. iPhone XS Max (Q56599233)

Should we add kilogram/gram or mass fraction as acceptable units, or should we convert those statements to use proportion (P1107)?

Masses should use mass (P2067). Mass fraction should use proportion (P1107). Would appreciate your help converting the adhesives a la https://www.wikidata.org/w/index.php?title=Q34677577&diff=1037094756&oldid=544002244
