While working on Amendments of the Constitution of India, I have found many amendments with multiple effective dates. So this property is needed as a qualifier to indicate the sections for each date, without creating separate items for those sections. Hrishikes (talk) 04:18, 15 November 2019 (UTC)


Values for applies to part (P518) need to be separate items. Articles of the Constitution may merit individual items, but all the sections of every Act, including constitutional amendment Acts, do not merit separate items. That's why I proposed for this parameter, "valid for", where the relevant sections can be added manually. Otherwise, we will need basically unnecessary creation of items for hundreds, even thousands of sections for various Acts. Hrishikes (talk) 02:07, 16 November 2019 (UTC)
Why not? We have items even for many Bible versicles, like John 3:16 (Q397709), Genesis 1:1 (Q4101743), and chapters, like Revelation 22 (Q16160740). I fear that a string equivalent of applies to part (P518) could be misused. Therefore, Symbol oppose vote oversat.svg Strong oppose. --Tinker Bell 18:44, 16 November 2019 (UTC)
@PKM: -- But that would need a joint qualifier. applies to part (P518) and section, verse, paragraph, or clause (P958) to jointly qualify the value for effective date, with a single value for the joint qualifier. I don't think I have seen such a thing yet. Hrishikes (talk) 03:07, 19 November 2019 (UTC)
  • As has been pointed out, the proposal appears to be defective. So I am withdrawing it. I'll rethink on the matter and submit an amended proposal, if required. Hrishikes (talk) 06:17, 19 November 2019 (UTC)
