Motivation

Hello! For the second time I propose a new property. This property is "period of lactation", I believe this is necessary, since there is no way to specify the period during which milk feeding occurs in the animal. Arbnos (talk) 00:56, 7 January 2020 (UTC)

  @Succu: what problem do you see? ChristianKl ❪✉❫ 15:04, 14 January 2020 (UTC)

• Comment: In general, I'd recommend against ever using a "month" (which can be anywhere from 28 to 31 days) as a unit for natural processes. --Yair rand (talk) 17:10, 12 January 2020 (UTC)

• Marked as ready - @Succu: can you explain why you object to this? --DannyS712 (talk) 21:07, 22 January 2020 (UTC)
  • @User:ChristianKl and DannyS712: nobody of the supporters gives a rational. Why should I give one for my oppose? But if you want one: domain is not "taxon". We should be more carefully with our property definitions. --Succu (talk) 21:40, 23 January 2020 (UTC)
    • Support is generally taken as "per nomination" --DannyS712 (talk) 21:47, 23 January 2020 (UTC)
      • @DannyS712: Are you referring to text below "Motivation"? There is no property definition and there are no references to define that term. --Succu (talk) 21:56, 23 January 2020 (UTC)
        • Yes, I meant the motivation --DannyS712 (talk) 22:16, 23 January 2020 (UTC)
          • Is the subject of this item lactation period (Q1801206) (my guessing)? Should the property domain be restricted to mammal (Q7377)? litter size (P7725) was created by you. Any idea what is litter size about? --Succu (talk) 22:32, 23 January 2020 (UTC)
    • @Succu: This a common life history trait. See the AnAge (Q78161166) example: Homo sapiens where this is called weaning. Taxon is the right domain for instance of (P31) checking. Should be able to add a subject type constraint (Q21503250) with a class (P2308) of mammal (Q7377) and a relation (P2309) of parent taxon (P171). --Bamyers99 (talk) 23:24, 23 January 2020 (UTC)
      • I think you'd need a Template:Complex constraint for that. I don't think one could currently do better than "taxon" on type constraints. The textual description in the "domain" field above can be more explicit. --- Jura 11:42, 24 January 2020 (UTC)
        • It's possible to do that. This is an example for GrassBase ID (P1832). The domain of this property is Poaceae (Q43238). Unfortunately a similar query for MSW ID (P959) is not working at the moment. --Succu (talk) 20:01, 24 January 2020 (UTC)
  • @Succu: 3 support votes and one opposition vote are by itself enough to create a property. If you however have good reasons against it's creation, I consider it valuable to know those. ChristianKl ❪✉❫ 18:11, 24 January 2020 (UTC)
    • I mentioned some. Another one: the source AnAge (Q78161166) is licenced as Creative Commons Attribution 3.0 Unported (Q14947546) not CC0. --Succu (talk) 19:05, 24 January 2020 (UTC)
• @Arbnos, ديفيد عادل وهبة خليل 2, ChristianKl, Bamyers99, DannyS712:  Done --Tinker Bell ★ ♥ 21:03, 24 January 2020 (UTC)
  • @Tinker Bell: You voted and should not have created this property. Would be nice to inform me about the creation too. --Succu (talk) 21:13, 24 January 2020 (UTC)
    • @Succu: Sorry, I realized that I forgot to inform @Jura1: too. About the property, the policy only says that a property creator should not create a property that he proposes himself. That is why we wait until a consensus is reached. --Tinker Bell ★ ♥ 21:22, 24 January 2020 (UTC)
      • @Tinker Bell: Jura1 didn't vote. My recent concerns are ignored by you (e.g. CC0). Not to create a property by someone who is involved in the process should be self-evident. --Succu (talk) 21:37, 24 January 2020 (UTC)
        • @Succu The property proposer never mentioned AnAge as a source. I was the one that mentioned it to back up my claim that the property is a common life history trait. I agree that AnAges license is not compatible with CC0 and can not be used as a source. --Bamyers99 (talk) 21:52, 24 January 2020 (UTC)
          • @Bamyers99: then why do you import values (one! example) from this datasource? --Succu (talk) 21:59, 24 January 2020 (UTC)
            • @Succu It wasn't until your comment above about AnAge not being CC0 that I re-evaluated my usage of it as a source and decided that I am going to have to re-source or remove the claims that I created. --Bamyers99 (talk) 22:20, 24 January 2020 (UTC)
              • I doubt you are careless. The values of four properties are at stake! Not to mention again a clear defintion of these other properties: litter size (P7725), gestation period (P3063) and egg incubation period (P7770). --Succu (talk) 22:37, 24 January 2020 (UTC)
          • Bamyers99, yes, I don't know AnAge.--Arbnos (talk) 23:26, 25 January 2020 (UTC)
