Hi all,
looking into [1] I read that Wikidata supports 358 languages. Is it still
true? For example, I tried to add label in language coded as "nan" (defined
in ISO 639-3) and it worked. However it didn't worked for e.g. "arb", which
is also part of the ISO 639-3 standard. So how many?
Thanks
Jan

Hello,
I have a SPARQL query that returns French labels of people with the family
name (P734) Labrousse (Q25273100), sorting them by label:
http://tinyurl.com/hq44ea8
The problem is that French rules for sorting are not applied: Élisabeth
Labrousse and Émile Labrousse should be between Audran Labrousse and Ernest
Labrousse, and not at the end of the results.
This seems conform to SPARQL specifications (ordering is undefined for
literals with language tags):
https://www.w3.org/TR/2013/REC-sparql11-query-20130321/#modOrderBy
Some SPARQL engines like Dydra use language tags to sort strings:
http://blog.dydra.com/2015/05/06/collation
It seems that Blazegraph should be able to do the same thing (using ICU
library), but the documentation is old (yep, 2013 is old ! :p) and I don't
know how WDQS is configured:
https://wiki.blazegraph.com/wiki/index.php/Unicode
Is there a solution to use French (or other languages) sorting in WDQS?
Thanks,

Hi,
I created "Wikidata property for items about software" https://www.wikidata.org/wiki/Q25857383 modeled after "Wikidata property for items about works" https://www.wikidata.org/wiki/Q18618644. It is my understanding that it will automagically display all properties that are an instance of "Wikidata property for items about software" in the "Software" part (which does not exist yet) of https://www.wikidata.org/wiki/Wikidata:List_of_properties/all
There also is an existing "Wikidata property for software" https://www.wikidata.org/wiki/Q21126229 which seems identical but worded slightly differently. I realize creating a new item with an identical purpose was a mistake but I don't know how to remove this new item. And I don't understand why properties that are instance of "Wikidata property for software" do not show in https://www.wikidata.org/wiki/Wikidata:List_of_properties/all.
I would very much appreciate any advice you may have on this topic :-)
Cheers

Hi all!
First of all, let me say that we all love the SPARQL endpoint, it's a
great service and it has become essential to how we interact with
Wikidata and run our bots. Great job by Stas and others!
I am also aware that it is still in beta mode. There is just one
issue, which plagues us and I have filed a bug report regarding that
in Sep 2015 (https://phabricator.wikimedia.org/T112397), so the issue
got alleviated, but it turned out that it did not get fully resolved:
-Occassionally, data written to an item in Wikidata via the API does
not make it into the triple store. (Frequency of the issue is hard to
determine)
-It is a crucial issue because it can lead to data inconsistency by
creating duplicate items or incorrect properties/values on items.
-It seems to happen while the SPARQL endpoint is under high load (just
my impression)
How data is affected:
-New data does not make it into the triple store
-Updates to and merges of items do not make it to the triple store, so
'ghost items' are returned which have actually been merged or queries
show/miss resutls/items incorreclty because freshly added/deleted data
has not been completely serialized.
Example: item https://www.wikidata.org/wiki/Q416356, a protein,
recently got added protein domains via the 'has part' property. This
did not show up in SPARQL queries and a DESCRIBE query for that item
returned that these triples were not there indeed. (item has been
modified, so it is fine now.)
A solution seems to be to modify the item as this seems to trigger
re-serialization. But this is certainly not practical for larger
imports. Furthermore, as long as such an item does not get modified,
data could be missing/ghosting from/in the triple store for weeks or
even months. And it turns out to be quite difficult to determine how
much of a certain import effort finally made it into the triple store,
if you do not want to iterate through all items modified and check if
everything is in the triple store, which would take significant
amounts of time.
Could you maybe give us more info on the status of this issue and if
we could do something to help alleviating it?
Thank you!
Sebastian

Hello --
There is a new *Drag'n'drop gadget* available in Wikidata > Preferences >
Gadgets
https://www.wikidata.org/wiki/Special:Preferences#mw-prefsection-gadgets
* Drag'n'drop*: Add statements and references from Wikidata or Wikipedia
by dragging and dropping them.
Please note that there are issues with the gadget.
I would like to evangelize this gadget but for my purposes it is not
functioning
---> i.e., I drag the reference and get a shadow image of text and even
after waiting 5 minutes the reference does not apply; refresh clears the
attempted addition
It might be a browser issue, but I have tried it on both Mac and PC, as
well as on Chrome, Firefox, Safari, and SeaMonkey with exactly the same
unsuccessful results. I have talked with Magnus about this (he is not
having the problems I have had). It might also be a Wikidata response
issue, but I think that issue was resolved.
Currently if you use Wiki Markup and want to use one of the four Cite
templates via the RefToolbar these templates I don't think will transfer
- Cite books: not configured. Will get error message
- I have not tested Cite web, Cite journal, Cite news, but assume none of
these are configured to be captured by this tool.
Obviously to configure the tool to work with these RefToolbar citation
templates would be significant amount of time & effort.
But if this tool was fully functional and robust -- and was able to
transfer ALL of the piped data -- it would allow for a great
interoperability of citations between Wikipedia and Wikidata.
I don't build citations without using templates, as my assumption is that
templates are more machine readable and more useful -- and are more
consistent -- but obviously others are using different approaches. I assume
bare urls are probably the most transferrable. But those didn't work for me
either, so.....
I really appreciate the fact that this gadget is available and the hard
work it took to create it. Magnus has been very patient and kind offlist
trying to problem-solve the issues I have had.
I just wanted to follow up and provide this information, as it seems an
important tool for us citation-focused editors.
Best,
- Erika

Something very weird is going on with Serbian language on Wikidata, so I wanted
to draw more attention to it. As always, this is probably applicable to Chinese
etc. as well.
It used to be that, if someone visits Wikidata from Serbia, Serbian language
did
not appear in the list of languages for adding label and description. This is
described in https://phabricator.wikimedia.org/T121747
However, as of right now, if someone visits Wikidata from Serbia, he will get
Serbian language twice: in Cyrillic (српски) and Latin (srpski) variant.
To my
knowledge, it has never been discussed to conclusion whether there should be
independent labels for the variants. Either way, one of the consequences of
this
is that all the Serbian labels that have been entered so far are invisible in
this list.
It gets even funnier if you go to
https://www.wikidata.org/wiki/Q3711?uselang=sr-el since now you get Serbian
three times: as "srpski (latinica)", "Serbian (Cyrillic script)" and
"српски".
It appears that the first is sr-el, the second is sr-ec and the third is the
new
sr-cyrl.
I didn't want to play with editing, since this is a mess already. It appears
that this is caused by an attempt to fix T121747 while simultaneously changing
Serbian-language codes (https://phabricator.wikimedia.org/T117845). Either way,
I believe it warrants more attention.
Hey folks :)
Based on requests here Denny and I have worked on getting the Primary
Sources Tool code moved from the Google to the Wikidata organisation.
This has now happened and it is available at
https://github.com/Wikidata/primarysources from now on. I hope this
will lead to more contributions from more people as I believe it is an
important part of Wikidata's data flow.
Cheers
Lydia
