Welcome to Wikidata, Dan Koehl!

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.
  • User options – including the 'Babel' extension, to set your language preferences.
  • Contents – The main help page for editing and using the site.
  • Project chat – Discussions about the project.
  • Tools – A collection of user-developed tools to allow for easier completion of some tasks.

Please remember to sign your messages on talk pages by typing four tildes (~~~~); this will automatically insert your username and the date.

If you have any questions, don't hesitate to ask on Project chat. 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! Sjoerd de Bruin (talk) 09:31, 11 December 2014 (UTC)

December 2014Edit

  Hello, I'm Sjoerddebruin. I wanted to let you know that I undid one or more of your recent contributions because it didn't appear constructive. Feel free to use the sandbox for test edits. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks! --Sjoerd de Bruin (talk) 09:31, 11 December 2014 (UTC)

(Which I did, I left Sjoerd de Bruin a message, it was strange, and I had no bad intentions - as always - don't know what happened. Dan Koehl (talk) 12:03, 28 March 2015 (UTC)



Hi, would you mind changing "no" to "nb" in your babel box? We're trying to get rid of "no", see phab:T102533 :) Danmichaelo (talk) 21:11, 4 June 2016 (UTC)

@Danmichaelo:, its   Done Dan Koehl (talk) 21:57, 4 June 2016 (UTC)


Hi, Dan. Wie geht es? Just touching base here; noting that you are clearly familiar with Wikidata. Presumably enough to be able to see how its facilities could help a WM genealogy site. I've read the second newsletter and most of the META talk page (which I hadn't seen before). (I must confess that I couldn't remember where we had met when I got your email!! Sorry - 76-year-old memory.) Robin Patterson (talk) 05:12, 6 March 2017 (UTC)

Hi @Robin Patterson:, mir gehts ganz gut, danke. Thanks for a nice greeting here, Yes, I think I have done a couple of things here, so I could actually start with a smaller project. But are you sure its totally OK, to submit genealogy records here, from pretty unknown people? Dan Koehl (talk) 05:42, 6 March 2017 (UTC)


Please have a look at Wikidata:Administrators' noticeboard. Thx. --Succu (talk) 22:53, 14 February 2018 (UTC)

Frédérique ChamsonEdit

Hi there,

according to [1], Frédérique Chamson never was a member of the 'Académie de Nîmes': that's the reason of my removal. Regards, 10:19, 10 September 2018 (UTC)

I see that @, sorry for being suspicious, and thanks for taking time to explain, I will revert my edit! Dan Koehl (talk) 10:26, 10 September 2018 (UTC)


Why you revert edits? I only added the name in the other language and deleted repeated information... where I mistake? -- 21:42, 10 September 2018 (UTC)

Sorry @, I see I did a mistake, I reverted my edits. Dan Koehl (talk) 21:48, 10 September 2018 (UTC)

Re: Q20008383Edit

Hi Dan. I removed that data because it was a spam vandalism and it was removed today by a itWiki admin as you can see here-- 08:08, 17 September 2018 (UTC)

Sorry for the mistake, thanks @ Dan Koehl (talk) 08:11, 17 September 2018 (UTC)


As said, could you please help me merging Édouard Bondurand (Q56313860) and Édouard Bondurand (Q55770981) (same person)?

Thanks in advance, 11:28, 17 September 2018 (UTC)

Yes now its   Done. Dan Koehl (talk) 11:30, 17 September 2018 (UTC)

Congratulations, Dear Administrator!Edit

English | español | français | Nederlands | +/−

An offering for our new administrator from your comrades... (our gift is better than the one at Commons or Meta)

You have your gun; now here's your badge: {{User admin}}/{{#babel:admin}} and {{Admin topicon}}. Enjoy!

Congratulations! You now have the rights of administrator on Wikidata. Please take a moment to read the Wikidata:Administrators page and watchlist related pages (in particular Wikidata:Project chat, Wikidata:Requests for comment, and Wikidata:Administrators' noticeboard), before launching yourself into page deletions, page protections, account blockings, or modifications of protected pages.

Please feel free to join us on IRC: #wikidata-admin @ irc.freenode.net. If you need access, you can flag someone down at @ irc.freenode.net. You may find Wikidata:Guide to Adminship to be useful reading. You may also want to consider adding yourself to meta:Template:Wikidata/Ambassadors, and to any similar page on your home wiki if one exists. (Check Wikipedia:Wikidata/Wikidatans (Q14964498).)

Please also add/update the languages you speak to your listing at Wikidata:List of administrators. You may also like to add your username to this list if you would not like that items you delete at RfD get marked as deleted automatically. Again, welcome to the admin corps!

Lymantria (talk) 10:21, 19 September 2018 (UTC)

Thank you @Lymantria:, will do everything requested above, and read through well! Dan Koehl (talk) 10:50, 19 September 2018 (UTC)
Congrats. I hope your adminship makes interaction the between WD and WS more seamless. Good luck fighting vandalism here. --Succu (talk) 19:59, 19 September 2018 (UTC)
Thank you @Succu:, yes, although I view an adminship merely as a tool against vandalism, I will in any case try to do my best to improve the interaction. Maybe Project Wikidata on Wikispecies, the collaboration platform with Wikidata:Wikispecies can serve as one way of improving communication and cooperation? Dan Koehl (talk) 20:24, 19 September 2018 (UTC)
I think both are dead ends for a while now. But lets see... --Succu (talk) 20:29, 19 September 2018 (UTC)

Roland Paulze d'Ivoy (Q54554745)Edit


For Roland Paulze d'Ivoy (Q54554745) I removed the nobility title "count" because he and his family are not "count" it is a fake title and this family doesn’t belong to the nobility :

This family and its fake title of count is listed in the book « A quel titre » an authoritative dictionary of Fake nobility in France.

Charondas , A quel titre?, volume 37,Les Cahiers nobles, 1970

Traduction in english : « Paulze d’Ivoy (comte) : Fake nobility, bourgeois 18 century »

I'm sorry to not having indicated this when I made the correction, but thank you to understand the legitimate reason of my correction. -- 19:08, 4 October 2018 (UTC)

I see @ I also see that when I reverted your edit, at 2018-10-03 21:24‎, I had checked the Wikipedia article, where mentioned as count on frwiki (comte de La Poype) but user Hictorv on frwiki seems to have changed this at 21.21, after I had read the page, and the link with the mentioned source for that he was not a count, is difficult to read, the direct link seem to mention the term comte and also baron, while the link to an archived version goes to a page where I cant read about this person at all... So sorry if yu think I did a mistake, but when I reverted your edit I had just read the article on frwiki, where he was mantioned as count, and appearently the user who changed the article did that after I read it. Interestingly, this is the only edit that user @Hictorv: has ever done on a Wikimedia server. A truly uniqie input, one single edit, from an acount fr:Utilisateur:Hictorv which was created 2018-10-03T23:12:54, just a second before the edit...?
Anyhow, If I did a miste, I apologize. Dan Koehl (talk) 22:13, 4 October 2018 (UTC)
No problem,
I made some researches, in fact its a little bit misleading : there was a old family whose name was "de la Poype". This family was baron and count de la Poye. In the 19th century, the last woman of this family married a member of the family Paulze d’Ivoy [2]. Their son Roland Paulze d’Ivoy added to his name that of his mother "de la Poype" and took the title of « count » but he was not noble no more than "count", that's why this second family "Paulze d'Ivoy de la Poype" is mentioned as fake nobility and using a fake title.
By the way, congratulations on your election as administrator. -- 04:07, 5 October 2018 (UTC)


Hi, don't forget to sign your commments. Stryn (talk) 10:26, 8 October 2018 (UTC)

Thanks for reminding @Stryn:, which edit are you referring to? If its the comments left by means of Huggle, it seems the script is uncomplete. Im happy to look into this, and would appreciate to do it do it together with someone. Dan Koehl (talk) 10:48, 8 October 2018 (UTC)
I'm referring to User talk: I needed to check from edit history who left the comments there. So it seems to be related to Huggle then. Hopefully someone can fix it soon. Stryn (talk) 10:55, 8 October 2018 (UTC)
@Stryn:, I think I managed to update 2 of the scripts, please see Template:Uw-vandalism, Template:Uw-vandalism2, Template:Uw-vandalism3, Template:Uw-vandalism4 and Template:Block? Dan Koehl (talk) 11:58, 8 October 2018 (UTC)

En stjärnaEdit

I Wikidata:Database reports/without claims by site/svwiki är ett par klasser överrepresenterade. Det handlar om travhästar och stjärnor. Borde man inte kunna mass-fixa åtminstone ett enkelt påstående till dessa två klasser så vi kan koncentrera oss på de knepigare fallen för hand? -- Hårig banan (talk) 05:58, 23 October 2018 (UTC)

Jag håller med, @Hårig banan:. jag kan undersöka möjligheterna om du vill, eller har du redan gjort det? Dan Koehl (talk) 08:22, 23 October 2018 (UTC)
Jag är inte så bekant med vilka möjligheterna är till massredigering. -- Hårig banan (talk) 09:54, 23 October 2018 (UTC)

Tedi AleksandrovaEdit

Hello I see you've removed my edits stating Tedi Aleksandrovas real age. but she is really born in 1981 and not 1990 as she claims.

Q57394958 (republish)Edit


Thanks for your care of Wikidata's information quality. In the case of Q57394958, it's possible to republish this item? This element is involve in a modelling project of Infobox in french from Archives Institution and their collections (see page of the projet on french Wikipédia).

I remain at your disposal for further information.

Thanks in advance

P.S. @Tomo8 5:

Dear @2le2im-bdc, Tomo8 5:, Q57394958 is restored. Dan Koehl (talk) 20:58, 4 January 2019 (UTC)
Dear @Dan Koehl:, Great! Thanks a lot. We will work on it next week. We hope to fix the all quickly. @Tomo8 5: --2le2im-bdc (talk) 21:11, 4 January 2019 (UTC)


Hello, Dan! Could you please merge Philippe Bord (Q58007736) with Philippe Bord (Q61613876)? This is a duplicate... 16:39, 7 February 2019 (UTC)

  Done @ Dan Koehl (talk) 16:46, 7 February 2019 (UTC)
Hi! Could you please do so for Henry François Garcin (Q57245971) and Henry François Garcin (Q60723274) too? Best regards, 14:41, 13 March 2019 (UTC)
(talk page stalker) @ Done, btw you can do that yourself, see Help:Merge. and Happy editing! ‐‐1997kB (talk) 15:00, 13 March 2019 (UTC)
Thank you! But I've no preferences, while I'm not a registered contributor... 15:46, 13 March 2019 (UTC)



You can help solve a mistake, mixed duki, a place, and es:Duki, a person.

Thanks Trierweiller (talk) 16:07, 7 June 2019 (UTC)

Admin inactivityEdit

Hello! Unfortunately, you have not made the required 5 admin/property creator actions in the last six months, and per WD:A your admin rights were removed. Thanks for your service in the past. --Rschen7754 01:08, 4 July 2019 (UTC)

Thanks and I understand @Rschen7754:, Ive been training elephants on 2 locations in Cambodia, and simply have too much real life presently. I hope to return later with more energy to serve the project on my 18th year!


Hi Dan,

this obviously wasn't an unconstructive removal. This claim was only there to help me to found some documentation about J. Reinaud. Now that it's done, it's no more useful. I allow myself to re-delete it.

Best, 10:19, 25 May 2020 (UTC)

Re: edit on Q3322116Edit

Hi Dan, my edits on wikidata items were aimed to remove the elevations imported by a bot from ceb.wiki, which are known to be wrong. You can check the items I corrected looking, for instance, on Openstreetmap. The elevations imported by ceb.wiki are sistematically underestimated. Thenks in any case for your patrolling work, -- 11:20, 25 May 2020 (UTC)

Oh I see @, sorry for my mistake. Ill restore your edit. All well! Dan Koehl (talk) 11:21, 25 May 2020 (UTC)
Thanks a lot! I wonder if it wouldn't be fine having a bot which does the work of erasing all these wrong elevations massively.-- 11:29, 25 May 2020 (UTC)-- 11:28, 25 May 2020 (UTC)
Good idea @, and I suggest that you apply for a bot at Wikidata:Bot requests. Dan Koehl (talk) 11:32, 25 May 2020 (UTC)
Thanks for the suggestion, I'll try to do it.-- 09:12, 29 May 2020 (UTC)
  Done!-- 09:35, 29 May 2020 (UTC)

Gong Chu (Q8335277)Edit

Hi, I find no source stating that Gong Chu was a citizen of British Hong Kong. He only lived there from 1949 to 1990. -- 06:38, 26 May 2020 (UTC)

I see, sorry for my mistake @, but you didnt explain your removal in the comments. I reverted to your version. All the best! Dan Koehl (talk) 06:42, 26 May 2020 (UTC)


It's not vandalism, it's improvement. 15:31, 1 June 2020 (UTC)


(I'm using English just in case other Wikidata editors may be interested in our conversation.)

Can I find a summary of the current status of the Lexeme project somewhere, in particular the Swedish vocabulary? I've been browsing documentation pages and spurious proposals, but the edit dates aren't entirely clear, and it's a bit tedious to cross-check revision histories all the time to find out... Are we supposed to add every single lexeme, form and sense yet missing manually, or are there plans to do bulk imports of data from free lexicographic sources, such as old editions of SAOB or SAOL (if possible)? Any negotiations with Isof or the Swedish Academy about getting a license to use more recent data going on? How about Project Runeberg (Nordisk Familjebok)?

I see that many lexemes have been imported from Wikidata labels, which have been imported from Wikipedia, which is sometimes confusingly wrong and has so been for years. As an example, the Swedish articles on "Evenemang" and "Händelse" were mixed up wrt to the English versions, and that error of course crept into the lexeme database leading to the Big Bang being something you might get an event management company to engage in... I think I have resolved that one now, after seven years of confusion, but there are probably others waiting to be discovered. Can we somehow search for those and get them fixed before adding more data?

I have also been looking into the English vocabulary and found a number of words with multiple meanings having been entered into the very same sense, such as "office" being described as "a room where administrative tasks are carried out OR a position within an organization" (something like that). I have fixed a few cases of such words, but there are several more, and there aren't even separate Wikidata items for them yet; "Archive" being a rather tricky example. I think we could do an automated search for any lexemes with English glosses containing the word "or" to get a list to work through (some instances of "or" are actually legit in glosses, though).

As I found English "of" totally messed up with two forms (but only one sense) due to an earlier merge with an item describing the lexeme itself as a genitive marker, I began working offline with a mammoth project, sorting out the senses of all the prepositions and corresponding grammatical constructs (such as cases) in any language, with the intent of presenting a table correlating of, from, by, to, when, in, into, i, om, på, ur, av, de, at, в, durch, für, gegen, ohne, um, aus, bei, mit, nach, seit, von, zu, an, auf, hinter, in, neben, über, unter, vor, zwischen and so on with each other; I think I found over 80 different prepositions in Danish (but only two in Russian), and English "in" has at least 23 different senses in the COD (9th edition)! This isn't something you can achieve asking volunteers to type in random glosses off the top of their head, but it requires a more systematic approach, I think. Might do the same with conjunctions, articles and numerals. Do you have any suggestions or other comments on that? --SM5POR (talk) 10:52, 9 August 2020 (UTC)

Call for participation in a task-based online experimentEdit

Dear Dan Koehl,

I hope you are doing good,

I am Kholoud, a researcher at King's College London, and I work on a project as part of my PhD research, in which I have developed a personalised recommender system that suggests Wikidata items for the editors based on their past edits. I am collaborating on this project with Elena Simperl and Miaojing Shi.

I am inviting you to a task-based study that will ask you to provide your judgments about the relevance of the items suggested by our system based on your previous edits. Participation is completely voluntary, and your cooperation will enable us to evaluate the accuracy of the recommender system in suggesting relevant items to you. We will analyse the results anonymised, and they will be published to a research venue.

The study will start in late January 2022 or early February 2022, and it should take no more than 30 minutes.

If you agree to participate in this study, please either contact me at kholoud.alghamdi@kcl.ac.uk or use this form https://docs.google.com/forms/d/e/1FAIpQLSees9WzFXR0Vl3mHLkZCaByeFHRrBy51kBca53euq9nt3XWog/viewform?usp=sf_link I will contact you with the link to start the study.

For more information about the study, please read this post: https://www.wikidata.org/wiki/User:Kholoudsaa In case you have further questions or require more information, don't hesitate to contact me through my mentioned email.

Thank you for considering taking part in this research.
