earliest date (P1319) or latest date (P1326) only cases should also evaluate mainsnak

If only earliest date (P1319) or latest date (P1326) is used the mainsnak should be evaluated, too. Currently this doesn't happen, e.g.:

• before 7 November 1635
  date QS:P,+1635-11-07T00:00:00Z/7,P1326,+1635-11-07T00:00:00Z/11
  (code: {{#invoke:Wikidata date|date|item=Q2470815|property=P569|lang=en}}; from Creator:Claudio José Vicente Antolínez).

Best solution would be

• "November 1635, before 7 November 1635"

if possible supported by Module:Complex date, better then now even

• "between November 1635 and 7 November 1635".

As I move data from Creator templates to Wikidata I was creating a lot of dates with P1319 / P1326 properties or with "circa". I would not want main snak ewaluated in none of the cases I set up as it was usually just the decade or century of the event. I do not know how to distinguish the cases where I would want to evaluate main snak and the cases where I would not want that. --Jarekt (talk) 01:21, 21 September 2017 (UTC)

Can you give an example where you would no want it? At least for Creator:Claudio José Vicente Antolínez even fetching the year precision date is better than just the latest date (P1326) qualifier and this is the same with the other cases I remember. --Marsupium (talk) 17:25, 21 September 2017 (UTC)

@Jarekt: Another example is the date of death (P570) of Cornelis Vroom (Q578120) where https://rkd.nl/en/explore/artists/82219 says "1661-09/1661-09-16, buried on 16 Sept 1661". earliest date (P1319) can't really be given, though just "16 September 1661" is not satisfying in my eyes. Of course mainsnak shouldn't be evaluated if both earliest date (P1319) or latest date (P1326) are set. I suppose this applies for the cases you refer to!? --Marsupium (talk) 19:21, 19 October 2017 (UTC)

"0000s" is not nice

Currently {{#invoke:Wikidata date|date|item=Q6787358|property=P571|lang=en}} gives "0000s" (test: 0000s AD

). That is not nice, should be at least 0s, perhaps this can be improved? --Marsupium (talk) 00:27, 19 October 2018 (UTC)

Time spans in various modules

We have time spans in various modules, see below! From Module:Wikidata art:

		if p.P580 or p.P582 then
			str = mw.ustring.format("%s (%s - %s)", p.value, p.P580 or '', p.P582 or '')
		elseif p.P585 then
			str = mw.ustring.format("%s (%s)", p.value, p.P585)
		else
			str = p.value
		end

and

		if p.P580 then
			str = mw.ustring.format("%s (%s - %s)", p.value, p.P580, p.P582 or '')
		end

From Module:Creator:

				description = string.format('%s (%s-%s)', description, args1.birthyear, args1.deathyear)

and

		if p.P580 or p.P582 then
			str = string.format("%s (%s–%s)", p.value, p.P580 or '', p.P582 or '')
		elseif p.P585 then
			str = string.format("%s (%s)", p.value, p.P585)
		else
			str = p.value
		end

From Module:Period:

			local getDate = require('Module:Wikidata date')._date
			local start = getDate(item, 'P580' , lang).str or getDate(item, 'P571' , lang).str
			local stop = getDate(item, 'P582' , lang).str or getDate(item, 'P576' , lang).str
			-- TODO: [[Module:Wikidata label]] has issues with RTL text when falling back to some LTR text,
			-- see the example at [[Template:Period/testcases]],
			-- has to get fixed there probably
			if start or stop then
				wikitext = string.format('%s (%s–%s)', wikitext, start or '', stop or '')
			end

Sometimes using something like "1789-1799" without and sometimes like "1789 - 1799" with spaces. Should we perhaps provide a function here to simplify harmonizing? Could also be useful for Template:ProvenanceEvent and others. --Marsupium (talk) 14:06, 19 October 2018 (UTC)
