Companies/corporate entities curated and grouped together at the Opencorporates website, useful in identifying companies belonging to the same group. Already in major use on enwiki. Gotitbro (talk) 14:31, 26 May 2018 (UTC)


It is like any other user curated property that already exist on Wikidata. Most OC groupings are pretty reliable and edited by multiple people (see for instance the entries for Facebook or Google). The example as the one above are rare and simply won't be included in Wikidata. Gotitbro (talk) 09:27, 29 May 2018 (UTC)
What about the "groupings" with 0 or 1 companies? --Gerwoman (talk) 18:48, 29 May 2018 (UTC)

  •   Oppose it seems to be apply to classify companies of the same group rather than to identify a group. In the first case, the datatype should be string and not external id.

    • @Gotitbro: Jura has a good point, is the domain of this property the companies in the group, or the group itself? If the first (i.e. many items would have the same value of this property) then this is more a classification scheme and not an identifier. ArthurPSmith (talk) 17:32, 30 May 2018 (UTC)
      • It identifies companies belonging to a single foremost entity, e.g., it should only be added to Google and not to any other item. Gotitbro (talk) 03:04, 31 May 2018 (UTC)
        • Could you add an item for that to the samples? "Google" is a vague as sample.
          For other sample Jio (Q18643672), in your proposal would it keep OpenCorporates ID (P1320) and also have this property?

          • Google. I had already linked Google and Facebook above so didn't do again and have provided the proposal example already. Yes, it would include both; one identifies the company while this identifies the companies belonging to it. Gotitbro (talk) 15:35, 31 May 2018 (UTC)
            • I meant the Wikidata Q-item, similar to Jio (Q18643672) in the template above.

              • Sorry, I am not understanding what you mean. Can you please clarify? Gotitbro (talk) 16:55, 31 May 2018 (UTC)
                • From your explanation, it seems to be Q95, not Q20800404 or any other item about Google on Wikidata.

  •   Comment Given the clarification above, I withdraw my vote. Still, if used as explained, it would mostly be redundant, e.g. Jio (Q18643672) using both this and OpenCorporates ID (P1320).
