Discussion

•  Comment How many ontologies are there, which would have values for this property? Isn't this handled in some way by the exact match (P2888) property or something like that? ArthurPSmith (talk) 18:08, 26 April 2024 (UTC)

  I think it's relatively typical for Ontologies to have root elements, so probably hundreds or thousands. exact match (P2888) does not contain information about what are root elements. ChristianKl ❪✉❫ 23:08, 26 April 2024 (UTC)

  That might be specified by a qualifier like chemical entity (Q43460564)exact match (P2888)http://purl.obolibrary.org/obo/CHEBI_24431object of statement has role (P3831)ontological root (Q104054982)? --Mormegil (talk) 06:03, 9 May 2024 (UTC)

  @ChristianKl:, could you please clarify the comments above by @Mormegil, AWesterinen:. @ArthurPSmith:, would you like to give any opinion? Regards, ZI Jony ^(Talk) 13:11, 13 June 2024 (UTC)

  Mormegil's suggestion is pretty much what I was thinking of.ArthurPSmith (talk) 11:31, 16 June 2024 (UTC)

•  Comment What is the use case for distinguishing the 'matched' property (exact match (P2888)) also as the ontological root? If I am working with the 'matched' ontology, I know its root. Andrea Westerinen
