Subject class constraint against Type "product" doesn't allow for GPC Segment or Family to be classified

For example, on clothing (Q11460) the current constraint is causing an issue applying the statement for codifying the Segment 67000000 on it with this GS1 GPC code P8957 property. Segments and Families within GS1 GPC are product subclasses and so this constraint should be removed or more appropriate constraints applied instead.

• Segment 67000000 Clothing
  • Family 67040000 Underwear
    • Class 67040100 Underwear
      • Brick 10001348 Socks

Yes, "product" is way too restrictive. GPC also includes product characteristics geo objects (origins) etc Vladimir Alexiev (talk) 01:31, 28 April 2022 (UTC)

Wikidata item of this property

Hi @Tpc:, thanks for deleting the other redundant prop!

Why did you add "Wikidata item of this property=product"? I think that is way too generic and I haven't seen such genericity on other props. I think only the specific item "Global Product Classification" should stay.

I think you can replace this with "is a=WD property related to Products". Cheers--Vladimir Alexiev (talk) 01:38, 28 April 2022 (UTC)

I mean @ToI:. Sorry to bother you, @TpC: Vladimir Alexiev (talk) 01:40, 28 April 2022 (UTC)
