Hoi, Please understand that providing functionality like query is something that has to fit into a continuously live environment. This is an environment where the Wikidata functionality is used all the time and where some of the underlying functionality is changed as well. The Wikidata development is not happening in a vacuum.
Given that we hope to get next week a new type of property, it should be obvious that Wikidata is not feature complete. When you add on extra functionality like a query engine, you add extra complications while the work is ongoing to get to the stage where Wikidata is feature complete for the data types.
Another aspect is that it is NOT the Wikidata team to decide what goes into production on Wikipedia projects. The Ask 1.0 functionality for instance is at its release level. It is now for other people to determine if they want to include it in. They have their own road maps and, it is not obvious for an observer what the rationales are. NB Ask 1.0 is also used in Semantic MediaWiki and it provides a query kind of functionality. Query does require some performance <grin> and what is too much </grin>.
So in one aspect there is a query functionality to be used in Wikipedia ea. What the query functionality will deliver that is still being build is not clear to me.
On another note, there are other projects that have lingering before they were implemented. Nothing new here. There have been other projects that had to change because of external pressures. Nothing new here.
If you want query functionality on the existing data now, there is a hack that works quite nicely. It makes use of data replicated to the labs environment. The replication is broken and given the holidays it has not been picked up for the third day now so the data is three days old. Thanks, GerardM

Jan,
my suspicion is that my predictions from last year hold true: it is a far more complex task to design a scalable and performant data model, query language and/or query engine solely for Wikidata than the designers of this project anticipated - unless they did anticipate and now knowingly fail to deliver.
You can check some threads from december last year, and they relate to even older ones: http://www.mail-archive.com/wikidata-l@lists.wikimedia.org/msg01415.html

Ok.
One is a bit disappointed seeing various projects to fail to deliver according to their original timelines... seems like there is not enough money in? Do you need more developers to perform better?

Hi,
so how things are going? Anything for testing already?
Nothing to test yet. As soon as there is I will send an email to this list. The current status is that we still need to make some final adjustments on the database schema and finish the java script part of the user interface as well as ranks.
Cheers Lydia
