Discussion[edit]

Comment[edit]

I think this property is so general, lacking enough accuracy for data extraction queries turn out. It includes a wide range of place domains: cities, sport clubs, organizations, shops, airports, etc. and maybe domains which are not considered as a place. As well as, it includes a wide range of time domains from millisecond to century. I propose to pick it into several properties. And the next and more delicate point is that the label is so vague if it is used for cities (meaning establishment), stores (meaning opening) and so on. — دوستدار ایران بزرگ (talk) 14:18, 12 June 2013 (UTC)

Qual è la differenza tra "creation date" (Property:P571) e "start date" (Property:P580)? --95.141.31.5 02:08, 7 July 2013 (UTC)
I seem to remember the original purpose of this property was quite narrow: foundation date or establishment date, in the formal sense. In the case of a modern company this would be the date that appears on the company's registration documents. Danrok (talk) 20:59, 31 August 2013 (UTC)

Qualifiers...[edit]

I think this property needs qualifiers. Stockholm was founded as an urban area 1960 (Swedish urban areas in it's modern definition are never older than that.), was founded as municipality 1971, founded as city-municipality 1863, as town/city 1463 and as settlement 1252.

It would also be nice to show how it was founded. -- Lavallentalk(block) 04:24, 1 September 2013 (UTC)

I agree, I notice that some old organizations in the UK were founded by a Pope, and then re-founded by a King or Queen, after the creation of the Anglican Church, and a the move away from the Catholic Church in England. Danrok (talk) 02:51, 2 September 2013 (UTC)
I would have thought that this property is a qualifier, or it needs splitting to be a number of things that have a start and end date.  — billinghurst sDrewth 11:55, 28 October 2013 (UTC)
I would like to add some thougts about Lavallens example. First, let's consider what the item Stockholm (Q1754) actually is. Is it a urban area? No, Stockholm urban area (Q94385) is. Is it a municipality? No, that is Stockholm Municipality (Q506250). Is it the city-municipality? No, we've got Stockholm city (Q10680648) for that. Is it about the town/city? Yes it is! But the fact that it was granted town privileges in 1463 was only a formal recognition of its status. The city/town/settlement was already there and it was already there in 1252 when Birger jarl wrote his letter granting privileges for Fogdö kloster. That letter just happens to be the oldest written record mentioning Stockholm. But Birger jarl wrote the letter in Stockholm and also wrote in the letter that it was from Stockholm. That indicates that there already was a settlement there noticable enough to be mentioned by the Jarl. The only source available stating the exact year for the foundation of Stockholm is Visby Franciscan chronicles (Q10716064) and that says it was founded in 1187. /ℇsquilo 14:10, 2 June 2014 (UTC)

Domain[edit]

Are there any plans to restrict the domain of this property to organizations? Or the intended domain is an artifact? If not, I see no sense in keeping that property, since Property:P580 has the same meaning. -- Apohllo 14 January 2015, 16:57

animal race[edit]

Would you say this property can be used to record when an animal race was first created (by crossing two other races), for example in Swabian-Hall Swine (Q769449) inception (P571) 1820? —DSGalaktos (talk) 21:53, 14 May 2015 (UTC)

Precision[edit]

It seems that Nativity of St. John the Baptist (Q18602467) was painted in the years 1633-1635. Which year should be used in this case? And what about the precision value if it is not exactly in a certain year but 'decade' would be too imprecise? Bever (talk) 04:04, 7 June 2015 (UTC)

@Bever: I think start time (P580) and end time (P582) are intended for this use-case, so . Or perhaps earliest date (P1319) and latest date (P1326), but I think those are intended for cases where the exact date is unknown, which isn’t the case here. —DSGalaktos (talk) 10:56, 7 June 2015 (UTC)

The renaming of this property without discussion[edit]

I don't see any discussion about the renaming of this property. The single word inception is misleading when the main component of this is that it is a date or a time, not the concept of wikt:inception. Can we please have the element of the time component added back.  — billinghurst sDrewth 14:13, 8 June 2015 (UTC)

Counter-argument: one “inception” statement can be used not only to record the time at which the inception occurred, but also other things. For example, see P:P1191, which is “first performance”, not “date of first performance”, since it’s often also qualified with location (P276), performer (P175), etc. – these qualifiers make more sense when you read them as “location of first performance”, not “location of date of first performance”. (For examples, see The Blue Danube (Q482621) and Symphony No. 9 (Q11989).) (However, in this particular case, I’m not sure if that argument applies – I haven’t seen many qualified inception (P571) statements.) —DSGalaktos (talk) 16:37, 8 June 2015 (UTC)

First half or quarter of a century[edit]

How should the first half of the 18th century be indicated? And how the first quarter of the 18th century? Or beginning of the 18th century? Romaine (talk) 02:57, 14 August 2016 (UTC)

As 18th century (precision: 100 years), with qualifiers earliest date (P1319) and latest date (P1326), I think. —Galaktos (talk) 18:03, 16 August 2016 (UTC)
Note that the new-ish qualifier refine date (P4241) supports this directly. - PKM (talk) 00:36, 18 January 2018 (UTC)
