Hi,
General case first: Many statements depend on time and have an end date
(e.g., population numbers). The general approach there is to (1) have a
qualifier that clarifies the restricted temporal validity and (2) make
the current statement "preferred". So your idea with the ranks was a

Does anybody see a specific danger of abuse if living people get to edit
their own data right now? Entering wrong claims deliberately would maybe
not be the biggest issue here (since it is already in conflict with
other general policies -- we do not want wron

TL;DR: This subtlety is important for powerful ontology modelling

Nice. We are running the RDF generation on a shared cloud environment and I

much RAM you needed to get this done?

Ok, now I have managed to add the Wikidata statements dump too.
And I have added a wikidata.hdt combined dump of all of the above.

Hi Christian,
Awesome :-) Small note: I just got a "Bad Gateway" when trying
http://data.wikidataldf.com/ but it now seems to work.
It also seems that some of your post answers the question from my
previous email. That sounds as if it is pretty hard to create HDT

Martynas,
Denny is right. You could set up a Virtuoso endpoint based on our RDF
exports. This would be quite nice to have. That's one important reason
why we created the exports, and I really hope we will soon see this
happening. We are dealing here with a very large project, and the

Hi Cristian,
As Daniel said, the live export is currently somewhat limited. However,
we provide RDF dumps that contain all the data:

This shows how the final live exports should also look (more or less),
and it could be a blueprint for somebody
Dear all:
Those of you active in research may be interested in submitting to a

Dear all,
I am happy to announce the third release of Wikidata Toolkit [1], the
Java library for programming with Wikidata and Wikibase. The main new
features are:
* Full support for the (now) standard JSON format used by Wikidata

Hi,
I fully agree with Thomas and the other replies given here. Let me give
some other views on these topics (partly overlapping with what was said
before). It's important to understand these things to get the subclass
