They're already on the test system and should go live with the next deployment.

Re: [Wikidata-l] Page history and properties

2013-04-03 Thread Sven 
Once we get qualifiers (and can specify time periods using them) then we will 
have all past values included, with qualifiers. So Obama, but also Eisenhower,  
Lincoln, Taft, etc.

Any word on when we get qualifiers, anyone?

[Wikidata-l] Page history and properties

2013-04-03 Thread Bináris 
A good question from huwiki:

When I click on an earlier version of the page in the history, will the
"then-value" of the property be shown or the current value?
If I read the 2013 version of [[United States of America]] in 2018, will
Obama be the president?

Sorry for causing some confusion here - this is my fault as I incorrectly
added the "order" option to the document. I just reverted this. There just
will be a sort field in query options, though this field is itself complex
(an array of sort expressions, where each expression specifies something to
sort by and a sort order).

For those who are interested, we already have a preliminary implementation
of the query language:

Re: [Wikidata-l] Wikidata queries

2013-04-03 Thread Yuri Astrakhan 
Petr, I have began specing out a migration to action=query in
http://www.mediawiki.org/wiki/Requests_for_comment/Wikidata_API , but that
RFC is not yet complete. Will probably work on it when I am in Amsterdam to
get that in sync with the Wikidata team... (and convince Denny that the
path is correct :))

'sort' defines how to bring the result items in a linear order, and 'order'
whether to start at the front or the end of the order.

In the content of the item, i.e. in the JSON structure that represents the
item.

What is the difference between 'sort' and 'order' QueryOptions?

And, I wanted to ask this for some time, where exactly are the 
statements being kept? I see no table that contains statements on the 
Toolserver, and nothing in Wikibase schema documentation.

Not decided yet. Probably it will be a JSON object, though, and edited
through an UI.

Yes, but it didn't seem a good fit, especially because the query module
works on the page metadata and the queries we discuss here work on the item
data.

I am not even sure it is much more complicated. But I am very worried it is
too different.
