Contact the development team

Wikidata development is ongoing. You can leave notes for the development team here, on #wikidata connect and on the mailing list or report bugs on Phabricator. (See the list of open bugs on Phabricator.)

Regarding the accounts of the Wikidata development team, we have decided on the following rules:

  • Wikidata developers can have clearly marked staff accounts (in the form "Fullname (WMDE)"), and these can receive admin and bureaucrat rights.
  • These staff accounts should be used only for development, testing, spam-fighting, and emergencies.
  • The private accounts of staff members do not get admin and bureaucrat rights by default. If staff members desire admin and bureaucrat rights for their private accounts, those should be gained going through the processes developed by the community.
  • Every staff member is free to use their private account just as everyone else, obviously. Especially if they want to work on content in Wikidata, this is the account they should be using, not their staff account.
On this page, old discussions are archived. An overview of all archives can be found at this page's archive index. The current archive is located at 2015/01.


Is it the time to enable links to Wikibooks?--GZWDer (talk) 05:42, 17 January 2015 (UTC)

How does 24th of February sound? Is there at least some demand from Wikibooks to have it at the moment? --Lydia Pintscher (WMDE) (talk) 11:34, 19 January 2015 (UTC)

Error when calling a deleted property[edit]

Using {{#Property: on non-existing properties gives an error message on fr:Wikipédia:Wikidata/Bac à sable. Given the content of the message, I don't think it is intentional. --Zolo (talk) 11:25, 17 January 2015 (UTC) clarified --Zolo (talk) 10:40, 20 January 2015 (UTC)

You can transclude property by label, {{#property:nature de l'élément}}. --JulesWinnfield-hu (talk) 16:56, 17 January 2015 (UTC)
It may be a good idea, to warn that the property could not be found but this sort of message looks buggish. --Zolo (talk) 10:43, 20 January 2015 (UTC)
THanks for bringing it up. Do you have a suggestion for what would be better there? --Lydia Pintscher (WMDE) (talk) 15:00, 20 January 2015 (UTC)
The "property not found for label P373" part (preferably translated) might have been clearer without the "rendering failure" part but I am not sure using error message is the best solution. The most likely reason for this sort of issue is that the property was relabelled/deleted. No big deal for the article, some info will be lost, but thhre is no need for a big red message that only a few can understand. Adding an "invalid property" tracker category sounds like a better approach. Those who don't know about these technical things won't be bothered, and those who do will find problematic pages more easily. With the current system, the issue can hardly be found using the search enging. This particular case was spotted only because an administrator -with some technical background- could not make sense of the message and notified it on fr:Discussion Wikipédia:Wikidata. --Zolo (talk) 15:57, 20 January 2015 (UTC)
Ok. Thanks for the clarification. I have created a ticket for it at phabricator:T87430. --Lydia Pintscher (WMDE) (talk) 11:22, 23 January 2015 (UTC)

JSON dumps[edit]

Since yesterday the directory is empty. Is this intended to be so? --Succu (talk) 10:14, 20 January 2015 (UTC)

No there was unfortunately a screwup which deleted them all. A new one is generating right now I'm told. --Lydia Pintscher (WMDE) (talk) 10:27, 20 January 2015 (UTC)
They are back by the way. Sorry I forgot posting it here earlier. --Lydia Pintscher (WMDE) (talk) 11:16, 23 January 2015 (UTC)
. Thx. I allready made use of the new one. --Succu (talk) 11:40, 23 January 2015 (UTC)

LM template[edit]

One af the admins kindly instructed me to use the LM template to get localised images in the translated help pages. I noticed that this help page already used the template so I uploaded to Commons the translated image. However the translated version of the help page still shows the English image. Is the LM template not working, or did I do something wrong? Thanks in advance. --Quico (talk) 16:23, 24 January 2015 (UTC)

@Qllach: Again me: I have purged the page and the file is now shown localised. Matěj Suchánek (talk) 16:46, 24 January 2015 (UTC)
Oh, great, thank you, very kind of you, I notice I still have to learn a lot! --Quico (talk) 16:58, 24 January 2015 (UTC)

Getting "unprocessed" data from the database?[edit]

Is there a simple way to get data as it is stored in the database, without any processing such as padding, converting binary numbers to characters, or the like? Would this be an example of how to get the data:

A related question is whether there is a specification about how data shall be provided to data consumers so data consumers can write reliable parsers?

Jc3s5h (talk) 19:06, 27 January 2015 (UTC)

I am not developer, but data are stored in MySQL database as I know. Some raw data can be found in the database dumps. Also page Wikidata:Data access can be useful maybe. — Ivan A. Krestinin (talk) 21:07, 27 January 2015 (UTC)

detailed information of language version of moved side links is lacking in revision history[edit]

could the language version of the moved site links be given again in the revision history. It is a very necessary quick possibility to check site link changes. --Oursana (talk) 19:12, 28 January 2015 (UTC)

Can you please give me a link to a diff with an edit summary you mean and what you think it should be? Thanks! --Lydia Pintscher (WMDE) (talk) 09:47, 29 January 2015 (UTC)
I understood this that Oursana meant if you look at some article history on Wikipedia, there's no way to see sitelink changes anymore. But better to wait Oursana's answer than guess :) --Stryn (talk) 16:59, 29 January 2015 (UTC)

Wordnet reference integration[edit]

For various applications, the mapping of wikipedia/wikidata references to wordnet references is useful. This is only true for common words (not for people, geo places, book and movie titles...).

Such links were partially integrated in FreeBase - not perfectly.

As far as I know, nothin like wordnet reference is currently provided by wikidata.

That would be a MAJOR improvement, since many people (like me) spend a lot of time trying to establish such mapping, probably incorrectly.

Future plans on this ?

Best regards,


I don't know wordnet in detail but it looks to me like this will need Wiktionary integration. That is still quite some time away as it needs major technical development. Planning is at Wikidata:Wiktionary. --Lydia Pintscher (WMDE) (talk) 09:46, 29 January 2015 (UTC)

Error without info when trying to add website property to Adland[edit]

I'm trying to add official website (P856) to the Adland (Q4683270) item, and every time I try to save the value, the operation fails without any information as to why. The error object returned states "failed-save" as the code, and has as its info field "<unknownerror-nocode>". Any reason why this would be? When I put in an invalid URL string it fails and informs me that it's due to not providing a valid URL, but when I provide the actual URL for Adland, it's just a silent failure. // coldacid (talk|contrib) 03:21, 30 January 2015 (UTC)
