Welcome to Wikidata, Magnus Manske!

Wikidata is a free knowledge base that you can edit! It can be read and edited by humans and machines alike and you can go to any item page now and add to this ever-growing database!

Need some help getting started? Here are some pages you can familiarize yourself with:

  • Introduction – An introduction to the project.
  • Wikidata tours – Interactive tutorials to show you how Wikidata works.
  • Community portal – The portal for community members.
  • Contents – The main help page for editing and using the site.
  • Project chat – Discussions about the project.
  • Tools – A collection of user-developed JavaScript tools to allow for easier completion of some tasks.

If you have any questions, please ask me on my talk page. If you want to try out editing, you can use the sandbox to try. Once again, welcome, and I hope you quickly feel comfortable here, and become an active editor for Wikidata.

Best regards! --Guerillero | Talk 21:59, 2 January 2013 (UTC)

Reasonator on Sergio Mattarella (Q3956186)[edit]

It seems we might have too many statements on the item. doesn't produce any results. --- Jura 17:28, 31 January 2015 (UTC)

It works in some languages, but not in all. is ok. fails. --- Jura 17:19, 7 February 2015 (UTC)
Seems I fixed it while working on my automatic description API... --Magnus Manske (talk) 20:29, 9 February 2015 (UTC)


getSitelinks and getWikidataItems functions only return no more than 1000 pages. Where's the bug?

By the way, the "Alma mater" game in Wikidata Game is still broken.--GZWDer (talk) 12:51, 3 February 2015 (UTC)

E Numbers[edit]

Hi Magnus, For some reason, you added instance of human to some E numbers. eg:

Also thank you so much on behalf of Project Food and Project Jobs and Occupations for helping with E numbers and UNII ids (which both have nice truckloads of data that could be imported)

--Teolemon (talk) 21:42, 5 February 2015 (UTC)

Fixing now. --Magnus Manske (talk) 22:04, 5 February 2015 (UTC)

Adding date of death to a living person[edit]

This edit back in July 2014 [1] added a death date to Q628151 with a reference to enwiki. According to Wikipedia, she is still alive! I checked the Wikipedia version at the time and cannot see how you picked up the information. I have fixed the entry, but just letting you know about the bug, plus I am curious where the date came from. Periglio (talk) 09:31, 8 February 2015 (UTC)

From here --ValterVB (talk) 10:05, 8 February 2015 (UTC)
Ah yes, I missed that! Just unfortunate timing then. Periglio (talk) 16:47, 8 February 2015 (UTC)

References in Wikidata Game[edit]

Hi, is there any reason for the Wikidata Game not to mention the Wikipedia article as a reference when adding a property? Indeed, we can be quite sure that the informations comes from this article since this is what this UI is for. ProgVal (talk) 11:01, 11 February 2015 (UTC) does not update (data week old)[edit]

See phab:T89583. Could you have a look at it? Thank you, Multichill (talk) 06:45, 15 February 2015 (UTC)

Structured Data on Commons update[edit]


After a delay in updates to the Structured data on Commons project, I wanted to catch you up with what has been going on over the past three months. In short: The project is on hold, but that doesn't mean nothing is happening.

The meeting in Berlin in October provided the engineering teams with a lot to start on. Unfortunately the Structured Data on Commons project was put on hold not too long after this meeting. Development of the actual Structured data system for Commons will not begin until more resources can be allocated to it.

The Wikimedia Foundation and Wikimedia Germany have been working to improve the Wikidata query process on the back-end. This is designed to be a production-grade replacement of WikidataQuery integrated with search. The full project is described at will benefit the structured data project greatly since developing a high-level search for Commons is a desired goal of this project.

The Wikidata development team is working on the arbitrary access feature. Currently it's only possible to access items that are connected to the current page. So for example on Vincent van Gogh you can access the statements on Q5582, but you can't access these statements on Category:Vincent van Gogh or Creator:Vincent van Gogh. With arbitrary access enabled on Commons we no longer have this limitation. This opens up the possibility to use Wikidata data on Creator, Institution, Authority control and other templates instead of duplicating the data (what we do now). This will greatly enhance the usefulness of Wikidata for Commons.

To use the full potential of arbitrary access the Commons community needs to reimplement several templates in LUA. In LUA it's possible to use the local fields and fallback to Wikidata if it's not locally available. Help with this conversion is greatly appreciated. The different tasks are tracked in phabricator, see .

Volunteers are continuing to add data about artworks to Wikidata. Sometimes an institution website is used and sometimes data is being transfered from Commons to Wikidata. Wikidata now has almost 35.000 items about paintings. This is done as part of the WikiProject sum of all paintings. This helps us to learn how to d:Wikidata:WikiProject Visual arts/Item structuremodel and refine metadata about artworks. Experience that will of course be very useful for Commons too.

Additionally, the metadata cleanup drive continues to produce results. The drive, which is intended to identify files missing {{Information}} or the like structured data fields and to add such fields when absent, has reduced the number of files missing information by almost 100,000 on Commons. You can help by looking for files with similarly-formatted description pages, and listing them at Commons:Bots/Work requests so that a bot can add the {{Information}} template on them.

At the Amsterdam Hackathon in November 2014, a couple of different models were developed about how artwork can be viewed on the web using structured data from Wikidata. You can browse two examples here and here. These examples can give you an idea of the kind of data that file pages have the potential to display on-wiki in the future.

The Structured Data project is a long-term one, and the volunteers and staff will continue working together to provide the structure and support in the back-end toward front-end development. There are still many things to do to help advance the project, and I hope to have more news for you in the near future. Contact me any time with questions, comments, concerns.

Quick statements oddity[edit]


I've just run a job using QS, with commands like:

Q749793 P1714   "charlotte-leslie"    S143    Q328
Q337453 P1714   "chris-grayling"      S143    Q328
Q332540 P1714   "chris-huhne" S143    Q328
Q267648 P1714   "chuka-umunna"        S143    Q328
Q263508 P1714   "clive-betts" S143    Q328
Q5144697        P1714   "colette-hume"        S143    Q328

However, every time it hits an example where the data already exists, it stops. I expected it to skip that line, perhaps with a warning) and execute the next. Was I being over-optimistic? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 19:35, 23 February 2015 (UTC)

This should be fixed now. --Magnus Manske (talk) 14:46, 26 February 2015 (UTC)
