Applies also to artworks?Edit

I am looking for a property to describe the time of installation/unveiling/inauguration of an artwork in public space (especially sculptures). Usually, an artwork is not "opened", so I wonder whether this property is the right one.--Leit (talk) 10:16, 4 April 2015 (UTC)

I don't know either. I am not really clear about the meaning of this property. It is currently used in Statua antropofica (Q1454323) but what exactly does it mean ? Apparently "inauguration", but that may not be self-evident. Actually the fact that this property is rather fuzzy makes it rather hard to use in Wikidata infoboxes. --Zolo (talk) 15:36, 24 May 2015 (UTC)


Relation to inception (P571) ?Edit

Most of the time, I think items use P571 for the date of opening. I don't think the sample above is helpful. --- Jura 08:05, 14 July 2015 (UTC)

@Jura1: It seems that inception (P571) is more general and date of official opening (P1619) is more specific for building but I must say it's unclear and very fuzzy ; maybe this two properties should be merged. Cdlt, VIGNERON (talk) 19:50, 29 May 2016 (UTC)
@Jura1: a (worthy?) exemple Infantry Museum (Q3329794) ? Cdlt, VIGNERON (talk) 14:09, 31 May 2016 (UTC)
Going back, it seems that it's actually fine, it's just that before this was created, another property was used for the same. -- Jura 17:29, 13 June 2016 (UTC)

Could it be that inception (P571) or start time (P580) is required with date of official opening (P1619)? Any business, event, building, etc. will have a period of development prior to the date of official opening, and when that time began could be called the inception or start time. These terms all have similar meanings. They difference needs to be clearly stated along with examples of proper usage. But as over five years has passed, this seems unlikely.

single value constraint removedEdit

In Germany, especially in Berlin, we face the issue, that a lot of station had been closed for a while and after the wall came down these stations have been reopened. So there are very often two opening dates and one closing date. So I have removed single value constraint. --GodeNehler (talk) 19:30, 30 July 2019 (UTC)
