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)

Fallback languages for labels on wdfist[edit]


Could you add labels from da/cs/sk/et/tr-labels to the ones displayed when there is no en-label? --- Jura 19:46, 25 March 2015 (UTC)

That should work now. --Magnus Manske (talk) 23:12, 25 March 2015 (UTC)
Great. Thanks. --- Jura 18:16, 26 March 2015 (UTC)

Mass edit with typo[edit]

Hi, last August there were a couple of hundreds edits like [1]. Probably employer (P108) instead occupation (P106) was intended (though the then relatively recent affiliation (P1416) might be an alternative). Do you still have the data for that run at hand and are able to fix it by the bot? -- Gymel (talk) 09:55, 28 March 2015 (UTC)

Ah, no, I don't have one-off data from August anymore... If the pattern is "occupation:university", then there are 37 instances of such. I'll go and fix some of these by hand. --Magnus Manske (talk) 15:17, 31 March 2015 (UTC)
I noticed them as constraint violations for occupation (P106) and from a few examples concluded the confusion with employer (P108). Whether it's just universities or broader in scope - my hope was you could tell... 37 is not such big a number, just fix some, I'll take on the rest. Sorry for having bothered you. -- Gymel (talk) 15:54, 31 March 2015 (UTC)
Sorry, it seems to be more, cf. this businessman. -- Gymel (talk) 16:06, 31 March 2015 (UTC)

Function "showQ" in User:Magnus Manske/wikidata useful.js (bis)[edit]

Hi Magnus, the "showQ" function is broken again. Could you fix it please? Thanks. — Ayack (talk) 09:40, 30 March 2015 (UTC)

Should work now. --Magnus Manske (talk) 15:09, 31 March 2015 (UTC)
Yep. Thanks a lot! — Ayack (talk) 15:23, 31 March 2015 (UTC)

French senators[edit]

Wow, I've just seen your tweet about Mix'n'match, thanks a lot. But I've made an error about formatter URL :/. The right one is not$1.html but$1.html with ID like senateur/robert_sylvie14229s, senateur-4eme-republique/aguesse_georges0427r4, senateur-3eme-republique/babaud_lacroze_leonide0398r3, senateur-2nd-empire/cambaceres_marie_jean_pierre_hubert0025e2 or senateur-communaute/dailly_etienne000397 which made matching a lot more difficult (I guess)... I'm sorry I made you do this work maybe for nothing. Tell me if I can do something about this. — Ayack (talk) 20:15, 31 March 2015 (UTC)

Well, I didn't create the property, or set the formatter URL. I guess the property is intended only for the current republic, as is my mix'n'match set. --Magnus Manske (talk) 22:24, 31 March 2015 (UTC)
Yes, it was my mistake. I created the property and set the wrong formatter URL. But now that all IDs have been imported on Wikidata from my mix'n'match, I plan to do the following actions:
  1. add by bot senateur/ at the begining of the IDs on Wikidata,
  2. change the formatter URL to$1.html on ID (P1808).
Then we will be able to use the property also for the former senators. Do yo see an issue with these actions? Thanks. — Ayack (talk) 10:47, 1 April 2015 (UTC)
Let me know once that is done; I will then modify the mix'n'match IDs, and try to import the other senators. --Magnus Manske (talk) 10:49, 1 April 2015 (UTC)
✓ Done. Thanks. — Ayack (talk) 20:07, 1 April 2015 (UTC)

Hi Magnus, you said you will try to import the other senators. Do you still plan to do it or is it too difficult? Thanks. — Ayack (talk) 19:23, 19 April 2015 (UTC)

✓ Done Now at 1,420. Names are last, first I'm afraid. --Magnus Manske (talk) 18:33, 20 April 2015 (UTC)
Great, thanks! — Ayack (talk) 18:47, 20 April 2015 (UTC)

Members of French Parliaments[edit]

I have no idea of the difficulty of doing this, but could you also import French MPs in Mix'n'match please? Website is and the property Sycomore ID (P1045). This time, I promise you that the formatter URL is right :). Thanks. — Ayack (talk) 10:47, 1 April 2015 (UTC)

Done. Importing matches from Wikidata now, so we can see which need to be done. --Magnus Manske (talk) 11:59, 1 April 2015 (UTC)
Great, thanks a lot! — Ayack (talk) 16:44, 1 April 2015 (UTC)

Filling the Getty[edit]

Hi Magnus Manske, both AAT identifier (P1014) and TGN identifier (P1667) are Getty Vocabularies related properties (like ULAN identifier (P245)). Both of them are barely used, but have a lot of potential. The data sets are available at for download. Could you add them to mix'n'match? For both I would probably take parentString as description. I just found CONA identifier (P1669). Could you add that one too? Thank you, Multichill (talk) 20:58, 1 April 2015 (UTC)

Wow, all three done now (wipes brow). --Magnus Manske (talk) 09:54, 2 April 2015 (UTC)
Great! Pff, that's going to be quite a bit of work to match everything :-)
Thanks for importing this. Multichill (talk) 20:03, 2 April 2015 (UTC)

Function "Images from wp" on wikidata usefuls is broken...[edit]

Hi Magnus,

Thanks so much for all the beautiful tools you build for us to improve wikidata :)

The last GUI update, as usual, broke some tools, and now, I cannot add an image through wikidata usefuls… it does not show images, or the "no images found" message… --Hsarrazin (talk) 21:56, 1 April 2015 (UTC)

This should be fixed now. --Magnus Manske (talk) 10:11, 2 April 2015 (UTC)

Coordinates precision from quickstatements[edit]

Hello, it seems that adding coordinates through quiskstatements always sets the precision to 1.0E -6 [2]. In that case, my inputs had mostly 4 decimals, would it be possible to detect that and set the precision accordingly ? --Zolo (talk) 12:42, 3 April 2015 (UTC)

Iconclass in Mix'n'Match?[edit]

Hello Magnus! You have recently added the Art and Architecture Thesaurus to Mix'n'Match. Quite awesome. That made me think: would it be possible (and would it make sense) to add Iconclass there too? We have Iconclass notation (P1256), which is IMO not yet properly used. Mix'n'Match would definitely help there. Iconclass is available as Linked Open Data - not CC0, but I think for merely matching the terms with Wikidata that's not necessary? Thank you! Spinster (talk) 15:22, 3 April 2015 (UTC)

Imported ~40K into mix'n'match. Happy matching! --Magnus Manske (talk) 18:14, 3 April 2015 (UTC)
Thank you! This will eliminate any chance of boredom during the Easter weekend. Spinster (talk) 18:40, 3 April 2015 (UTC)
@Spinster: I'm not sure this is going to work. Mix'n'Match is for making one-on-one matches between items here and some other dataset. With iconclass we have milkmaid (Q1934482): Iconclass ID: 47I22311, but other paintings about milkmaids can have the same iconclass id. Multichill (talk) 20:15, 4 April 2015 (UTC)
Iconclass is a strange beast indeed, and until now we have not treated it well enough on Wikidata. We have Iconclass notation (P1256) which must be used for connecting concepts on Wikidata with their corresponding Iconclass ID's (the milkmaid example you mention), and then there is depicts Iconclass notation (P1257) for connecting artworks with Iconclass ID's, such as Vermeer's Milkmaid at the Rijks. We Mix and Match with Iconclass notation (P1256). I think there are still many mistakes there, I'd like to fix those. That being said, I also think that just a small selection of Iconclass IDs will be 'matcheable' here, because Iconclass is a vocabulary tree where the branches very often express different concepts simultaneously (for instance 11H(ANTONINUS)119(+5) which is a saint with his attributes, and a cloak, and he's also protecting people - we would not cram that into one Wikidata item, would we?). Spinster (talk) 12:47, 5 April 2015 (UTC)
Oh, we have two properties. Didn't know that. That should probably get a bit better documentation. Multichill (talk) 13:06, 5 April 2015 (UTC)

User:Magnus Manske/ext-props.js[edit]

Hi Magnus, please add also BIBSYS identifier (P1015) to your gadget. Thank you, --T.seppelt (talk) 12:38, 6 April 2015 (UTC)

Done. --Magnus Manske (talk) 12:41, 6 April 2015 (UTC)

Reasonator being creative?[edit]

Hi Magnus, pinging about this strange thing: --Antoine_Isaac (talk) 10:23, 11 April 2015 (UTC)

Coordinate on reasonator[edit]

Coordinate on Reasonator don't work ((unknown/no value). example Po (Q643) (View with Reasonator) or Fishing Creek (Q5455008) (View with Reasonator) --ValterVB (talk) 17:05, 12 April 2015 (UTC)

Ping :) --ValterVB (talk) 11:14, 18 April 2015 (UTC)


Hi Magnus, for some reason I sometimes get logged out of mix'n'match. Than it's complaining I should log in to TUSC, but of course TUSC has been retired. Can you change this to widar with the authorization link? That also makes it easier for newbies. Thanks for adding personID (P1819) to the tool. I'm amazed that over 3000 links have already been made :-) Multichill (talk) 19:30, 14 April 2015 (UTC)

It's already using Widar. I'll try to hunt down the obsolete TUSC messages. --Magnus Manske (talk) 22:11, 14 April 2015 (UTC)

User:Reinheitsgebot edit-warring me![edit]

cf. [3] or [4]: I've invested considerable time during the last month to clean up the VIAF unique value violations here and fixing their cause (usually blatant nonsense copy-pasted in en:Template:Authority control). VIAF used to harvest en:WP's data and switched to harvesting wikidata instead just last month, fortunately in most cases the do not follow blindly VIAF values in the articles/items, however in some cases VIAF incorporated such wrong listings. I have no clue as for the source of your "Widar" edits, but it seems to be outdated enough that you should implement some additional checks before "updating" to items here to past property values. -- Gymel (talk) 13:14, 15 April 2015 (UTC)

Got a short, third-party list. Should be through with the VIAF now. Apologies for the inconvenience. --Magnus Manske (talk) 13:22, 15 April 2015 (UTC)
O.K., since everything still was in my watchlist I could revert the edits where appropriate (VIAF and ULAN identifiers). So we won't have a tight oscillating loop where we're feeding last month's VIAF wikidata harvest back into wikidata as this months wikidata VIAF harvest and at the same time they're acting vice versa (they probably will and therefore we mustn't) - glad to hear... -- Gymel (talk) 13:33, 15 April 2015 (UTC)
I do set ULAN coming from mix'n'match at the moment though. They should be mostly human-annotated. Problem is, if you just remove them, next round of updates may well re-create them... --Magnus Manske (talk) 13:37, 15 April 2015 (UTC)
FYI, of the ULANs you reverted, the majority seem to have been set by User:Spinster. --Magnus Manske (talk) 13:38, 15 April 2015 (UTC)
For which I sincerely apologize ... Is it best to steer away from ULAN matching for a while, if I understand correctly? Spinster (talk) 13:54, 15 April 2015 (UTC)
Nah, just don't trust the automatcher so implicitly ;-) Some of your matches had clearly different dates; just take a second to make sure it's the right item. --Magnus Manske (talk) 14:46, 15 April 2015 (UTC)
@Spinster: please do continue working on ULAN, just keep a close eye on the dates. I hope User:Multichill/Rijksmuseum creators RKD becomes complete in the next couple of weeks. Reminds me of something else. I'll ping you on the other topic. Multichill (talk) 20:41, 15 April 2015 (UTC)
The ULAN's I reverted should usally have been ULANs I already deleted during the last couple of weeks, i.e. either cases of wrong ULAN Ids in the right VIAF cluster or a corollary from wrong VIAF numbers in the wikidata item and bots spilling other identifiers from that cluster into the wikidata item. As I mentioned above, VIAF is not fooled easily by bad data but see the last sections of en:Wikipedia talk:Authority control/VIAF#OCLC_Mechanisms for a by no means complete list of error flavors even under the assumption that data here is perfectly in order. I think everything will be quite manageable unless someone decides to bot-import VIAF numbers based on the mapping to wikidata item numbers provided by VIAF dumps beginning from tomorrow (not quite clear: I noticed Wikidata-mappings in VIAF during the weekend, however the links were broken and now I see "Wikipedia" links again: maybe they aborted this aspect of this month's operational round completely and will retry next month). -- Gymel (talk) 16:09, 15 April 2015 (UTC)

RKDimages (P350)[edit]

Viele durch Reinheitsgebot hinzugefügte RKDimages (P350) Werte sind ungültig, z.B. Nauru (Q697), tungsten (Q743), Unione Calcio Sampdoria (Q1457). Mehr Fehler auf [5]. Pasleim (talk) 10:58, 18 April 2015 (UTC)--

On Wikidata:Database_reports/Constraint_violations/Mandatory_constraints/Violations#RKDimages_.28P350.29:_Type_work_of_art_.28Q838948.29 you can find a whole list. Not sure what happened Magnus, but you know the deal, if your bot creates a mess, you clean it up. I gave you rollbacker to make that easier. Multichill (talk) 16:59, 18 April 2015 (UTC)
Seems like the Q-number for the item and the numerical RKD id were exchanged for the edits ;-)  – The preceding unsigned comment was added by Gymel (talk • contribs) at 17:21, 18 April 2015‎ (UTC).
Those should be gone now. Will try to import them correctly later. --Magnus Manske (talk) 10:27, 19 April 2015 (UTC)
Thanks for taking care of this. Multichill (talk) 19:38, 21 April 2015 (UTC)

Ancient Greek nationality[edit]

I really like your new tool wrong nationality: I want you to know that ALL the items with nationality Ancient Greece (Q11772) are wrong, because ancient Greece isn't a state. This absurd information was unfortunately imported from Italian Wikipedia, where in the last two years I've often complained about the use of ancient Greek nationality. Thank you, --Epìdosis 10:07, 19 April 2015 (UTC)

Game mode not working for some catalogs on Mix'n'match[edit]

Hi Magnus, when I click on "Game mode" for CH-D or French senate (for example), the screen displays "loading" and then nothing (while CH-B works well). Could you have a look at it please? Thanks. — Ayack (talk) 11:03, 21 April 2015 (UTC)

Should work now. --Magnus Manske (talk) 17:13, 21 April 2015 (UTC)
Yep, thanks. — Ayack (talk) 17:29, 21 April 2015 (UTC)

First-grade humans[edit]

Reinheitsgebot has turned a few people into grade 1 listed buildings [6]. Maybe that refers to their graves or something, but their is no reference provided and I don't really know how to find out. --Zolo (talk) 06:27, 23 April 2015 (UTC)

RKDimage auto matches[edit]

Hi Magnus, in Mix'n'Match we ran out of auto matched items for RKDimages. Do you feel like having a shot at creating more auto-matched items? It's possible to extract the inventory number from the description. Take for example 105243 it has "inv./ SK-A-4925", if you take this inventory number and use WDQ you get the right painting item. Sometimes you'll see a variation like inv./ SK A 4878, this corrosponds to SK-A-4878. Do you think you can auto match some more items based on this? Multichill (talk) 11:40, 23 April 2015 (UTC)
