Hello,
I have a few questions about how statement qualifiers should be used.
First, my understanding of qualifiers is that they define statements
about statements. So, if I have the statement:
Q17(Japan) P6(head of government) Q132345(Shinzō Abe)
with the qualifier:
P39(office held) Q274948(Prime Minister of Japan)
it means that the statement holds an office, right?
It seems to me that this is incorrect and that this qualifier should in
fact be a statement about Shinzō Abe. Can you confirm this?
Second, concerning temporal qualifiers: what does it mean that the
"start" or "end" is "no value"? I can imagine two interpretations:
1. the statement is true forever (a person is a dead person from the
moment of their death till the end of the universe)
2. (for end date) the statement is still true, we cannot predict when
it's going to end.
For me, case number 2 should rather be marked as "unknown value" rather
than "no value". But again, what does "unknown value" means in
comparison to having no indicated value?
Third, what if a statement is temporarily true (say, X held office from
T1 to T2) then becomes false and become true again (like X held same
office from T3 to T4 with T3 > T2)? The situation exists for
Q35171(Grover Cleveland) who has the following statement:
Q35171 P39(position held) Q11696(President of the United States of
America)
with qualifiers, and a second occurrence of the same statement with
different qualifiers. The wikidata user interface makes it clear that
there are two occurrences of the statement with different qualifiers,
but how does the wikidata data model allows me to distinguish between
these two occurrences?
How do I know that:
P580(start date) "March 4 1885"
only applies to the first occurrence of the statement, while:
P580(start date) "March 4 1893"
only applies to the second occurrence of the statement?
I could have a heuristic that says if two "start date"s are given, then
assume that they are the starting points of two disjoint intervales. But
can I always guarantee this?
Best,
AZ

Heya everyone!
Today is Wikidata's first birthday. One year ago Q1 was created. This
is time for a lot of celebration and a bit of reflection. Join us over
at https://www.wikidata.org/wiki/Wikidata:First_Birthday for an
editorial on Wikidata's accomplishments and challenges by Sven, some
notes by me, a great interview and some cupcakes ;-)
Cheers
Lydia

Hi *Diederik,*
I saw your name on this post (https://blog.wikimedia
.org/2012/09/19/what-are-readers-looking-for-wikipedia
-search-data-now-available/).
I am looking for User Search log files. I could not find them in
http://dumps.wikimedia.org/other/search/.
Could you help me? I am very new in Wikipedia dump data.
best,
Edgard
Ok, I have now found and tackled the issue.
This was indeed a bug in EasyRDF that got fixed since we forked half a year ago.
I have updated easyrdf_lite now:
<https://github.com/Wikidata/easyrdf_lite/commit/025c32da17d82a51950230b80c2…>.
The respective patch for Wikibase is in review, see
<https://gerrit.wikimedia.org/r/86858>.
Having to maintain the fork is really a pain, I wish there was a better way to
do this. I think there's a strong use case for project that only need RDF
export, no import or serving. Being able to deploy the serialization code
separately would be very useful.
Nicholas, do you think it would be an option for EasyRdf to offer support for
this use case? The most obvious (but also rather painful) way would be to spin
off the serialization bit into a separate repository. But maybe it would be
feasible to provide a build script that could be used to carve/reduce the code
base to the parts needed in a particular scenario?

Cross-posting the announcement from the Wikimedia Blog. The details of the event are on Meta and we're also creating meetup.com pages for the local events. Check them out and RSVP if you're planning to attend – it'd be awesome to have folks from the wikidata community on-board. Looking forward to see you on November 9!
Dario, on behalf of the organizers
Join the inaugural Wiki Research Hackathon on November 9
Last summer at Wikimania in Hong Kong, the annual global Wikimedia conference, we (a group of Wikipedia researchers) discussed how we could make wiki researchmore impactful. In our work in academia and on Wikimedia projects, we saw a host of missed opportunities to share ideas, hypotheses, code, and research methods. We set out to create a space to bring researchers together with Wikipedians and facilitate problem solving, discovery and innovation with the use of open data and open source tools. Labs2 (L2) aims to build this space, by providing infrastructure and venues for collaborative wiki research.
Today we’re thrilled to announce the inaugural Wiki Research Hackathon – a global event hosted by Wikimedia Foundation researchers, academic researchers and Wikipedians from around the world on Saturday, November 9, 2013.
What
This hackathon is an opportunity for anyone interested in research on wikis, Wikipedia, and open collaboration to meet, share ideas, and work together. It is targeted at Wikipedia editors, students, researchers, coders and anyone interested in designing new tools, statistics and data visualization, and producing new knowledge about Wikimedia projects and their communities.
The goal of this event is to:
share knowledge about research tools and datasets (and how to use them)
ask burning research questions (and learn how to answer them)
get involved in ongoing research projects (or start new ones)
design new data-driven apps and tools (or hack existing ones)
Where
(Locations are approximate)
This hackathon will be held both as a series of local meetups (Perth, Mannheim, Oxford,Rio de Janeiro, Chicago, Minneapolis, San Francisco, Seattle, etc.) and virtual meetups (Asia/Oceania, Europe/Africa & The Americas) for those who can’t make it to the local events. An IRC channel (#wikimedia-labsconnect) and a Google Hangout open throughout the day will allow attendees to connect online.
How
Interested attendees can sign up for the event on Meta-wiki.
Local and virtual meetups are listed on theevent page. All you need to do is add your name to the list of participants for the event that makes sense for you.
Who
For any question about the event (including volunteering for a local meetup), you can reach us at wrh(a)wikimedia.org or leave a message on the hackathon’s talk page on Meta-wiki. We look forward to seeing you on November 9.

Hello everyone,
Here is the weekly summary over all the things that happened in Wikidata
since last week. This week includes quite a few development updates. Also
Echo has been enabled on Wikidata and Wikidata is also 1 year old next
Tuesday (the 29th). So stay tuned for some surprised next week while you
read the summary at;
https://meta.wikimedia.org/wiki/Wikidata/Status_updates/2013_10_25
Also in regards to the summary, a few changes have been made to the format
this week. These changes include the listing of closed RfCs under the
discussion heading and doing a weekly 'Help a task force out' under open
tasks for you, this week is the Roads tasks force. Enjoy!
Regards,
John

Google Code-In is a contest to introduce pre-university students (ages
13-17) to the many kinds of contributions that make open source software
development possible. Students must complete tasks (see examples), one
at a time. The Google Code-in 2013 contest runs from November 18, 2013
to January 6, 2014.
https://www.mediawiki.org/wiki/Google_Code-In
There has been a discussion in this list about listing little bugs ready
for newcomers. I'm sure there is also potential for documentation tasks
e.g. small tutorials or step-by-step guides. Also, do you have cleanup
tasks that someone must do (or program a little script / bot to do)? All
these are good potential tasks for Code-in.
What do you think?
We are currently preparing the proposal to apply by Oct 28, next Monday.
If you can add at least 5 tasks to the wiki page linked above then you
will be ready for the next level - if we are one of the organizations
selected on November 1.
If you have questions just ask, here or at the related talk page.
PS: Lydia is an expert Code-in mentor / org admin but I'm explicitly NOT
requesting her to get involved as she usually volunteers to so. This is
in fact a very good opportunity for new mentors with some free time and
a will to help new contributors that perhaps perhaps will stick around
and become Wikidata fans thanks to you.
