I am interested in this topic, spatiotemporal definition of places.

Can we set up a task force that would collect best practices and see if something is missing in Wikidata for describing historical places?

There are several academic projects that can contribute to this.
- Finnish spatiotemporal ontology SAPO
- Wikidata as a gazetteer / Humphrey Southall / PastPlace
- TopoTime / Karl Grossner, Elijah Meeks
- Pelagios 3

and there are many more

Best,
Susanna

Hi Sandra, Sjoerd and Wikidatans, 

In what ways would it be possible to add particular place qualifiers/claims/properties (incorporating Wikidata Geodata) to be linked with new time claims you suggest such as seasons or quarters ... for eventual use in an eventual film-realistic, 3D, interactive, group-build-able wiki virtual earth?  

Greetings, Scott

Hi Sandra,

For between dates, we have https://www.wikidata.org/wiki/Property:P1319 (earliest date) and https://www.wikidata.org/wiki/Property:P1326 (latest date) as qualifiers. You can set the claim itself on century or whatever then. You can also use P1326 for before dates, I think. Seasons is another thing, I think we need a new property for that. Same for quarters.

But I agree, it should be great if this was integrated more. Showing better suggestions before saving is another thing that could help.

Greetings,

Sjoerd

Hi folks,

I do lots of edits related to artworks. Many artworks (and, I assume, many other things) are dated in the following ways:

1. 'between 1850 and 1899’ - on Wikidata that could be ’18. century’ (yep, needs to be written like that) with qualifiers start date and end date ?
2. ‘between 1784 and 1787’ - on Wikidata ‘1780s’ with qualifiers?
3. ‘between 1878 and 1904 - on Wikidata... eeeehm?

I was wondering: can’t we express this without needing any qualifiers at all?

We can enter units as ‘320 cm plus/minus 7 cm’, right?
Might we also be able to say ‘1898 plus/minus six years’?

I can imagine we’d then also have an interface that helps you enter a ‘between date x and date y’ elegantly without needing to do any math.

Or would that not be possible?
I think it would be great to have, as it would make our dating conceptually much more accurate IMO.

Curious what others think.
Best, Sandra (User:Spinster)

p.s. On Commons we have an {{Other date}} template that’s used very frequently, that allows rich time/date expressions, and that I really love. Here’s the documentation: https://commons.wikimedia.org/wiki/Template:Other_date

Besides this ‘between’ concept, it also has, among other things
* before (date) or after (date) - also very common!
* seasons - you can say ‘Spring 1986’
* first/last half/quarter (year, decade, century) etc
Some might not be translatable to a period as I suggested above, but some may.
