Here's another nice query:
"Find all astronomical bodies on which Wikidata has some coordinates,
ordered by the number of coordinates that refer to them":

currently non-existing countries?
Because I have such code in my Python bot:

And even with so many filters, there is a bit strange "Kingdom of
Netherlands" which duplicates "Netherlands" but having only few cities.

Just to give an example of a slightly more complex query ;-) Note how we
use the expression (:P47s/:P47v) rather than :P47c to access the value

Hi all,
I am happy to announce the release of Wikidata Toolkit 0.4.0 [1], the
Java library for programming with Wikidata and Wikibase. The main new
features are:
* Full support of a variety of new Wikidata features (including
statements on properties and new datatypes)
* More robust JSON pa
the empty reference problem (a statement has a reference which
contains no data whatsoever; look for: "snaks":[]). Maybe somebody wants
to look into this (this should not really happen, even if the JSON were
serialized correctly).
Cheers,
Markus

Hi Stas,
Since the JSON dumps and EntityData exports are (largely) free of
errors, there is already code for fixing this problem. Maybe we could
just use this.
Cheers,
Markus

hat you would
have made some technical choices differently, but you should not be
frustrated because of that. We, too, have had many heated tech
discussions about Wikidata, and each of us has had to give up some
positions in the process.

Anyway, our discussion was about the role of RDF, not about a
comprehensive history of Wikidata. Nevertheless, be assured that if
anybody would contest the contributions of OmegaWiki, I will react in a
similar fashion.

Dear Gerard:
...
This is the essence of Wikidata. After that we can all complain about
the fallacies of Wikidata.. I have my pet pieves and it is not your RDF
SPARQL and stuff. That is mostly stuff for academics and it its use is
largely academic and not useful on the level where I want progress
ta this would actually be. Which also
depends on whether we would omit descriptions in languages that can easily be
covered by language fallback (e.g. no separate descriptions in de-ch and de-at).

import that is generated automatically --
should we in all of this cases switch to offering a web service that
gives you the data if you really need?
So, +1 for auto-generated descriptions, but -1 for not having them in
the data anymore.

Markus

Hi,
I got interested in subclass of (P279) and instance of (P31) statements
recently. I was surprised by two things:
(1) There are quite a lot of subclass of statements: tenth of thousands.
(2) Many of them make a lot of sense, and (in particular) are not
(obvious) copies of Wikipedia categor
capabilities
that allow you to analyse the data. Again, your requirements are welcome.
Cheers,
Markus
