Hm,
nice to read all the reasoning why queries are yet still not possible, but
I think we live in 2014 not and not 1914 actually... seems like the problem
is too small budget or bad management... can not really think of another
reason. How much do you think would it cost to make queries reality for
production at Wikidata?

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:

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?

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
