Welcome to Wikidata, Edelseider!

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, 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! --VIGNERON (talk) 16:20, 25 October 2018 (UTC)

Typography of FrenchEdit


For information, in French, proper names for bridges (and others things) like Beatus Rhenanus Bridge (Q20980965) start with a lowercase initial.

Wikidata:WikiProject sum of all paintings/Top work locationsEdit

You messed up the query. You should test it before you change a page and you should really test it before you undo my edits. Multichill (talk) 21:23, 1 October 2020 (UTC)

@Multichill: But I tested it, and I said so! Don't you believe me? What about assuming good faith? I had a high opinion of you, and now, that. Tsss. --Edelseider (talk) 05:34, 2 October 2020 (UTC)
This is what the query was:
SELECT ?item (COUNT(?item) as ?count) WHERE {
  ?painter wdt:P106 wd:Q1028181 .
  ?painter wdt:P31 wd:Q5 .
  ?painter wdt:P937 ?item .
} GROUP BY ?item
ORDER BY DESC(?count) 
You removed " ?painter wdt:P937 ?item ." turning it into:
SELECT ?item (COUNT(?item) as ?count) WHERE {
  ?painter wdt:P106 wd:Q1028181 .
  ?painter wdt:P31 wd:Q5 .
} GROUP BY ?item
ORDER BY DESC(?count) 
That doesn't work because the GROUP BY part references nothing. So not sure what you tested, but I'm sure it's not the query you saved.
Maybe you should assume good faith yourself and look into why someone undid your edit. Multichill (talk) 18:56, 2 October 2020 (UTC)
@Multichill: all I can tell you is that, as it now and was before, the list cannot be updated by ListeriaBot. When you click on "update manually", nothing happens. When I removed one criterion, the manual updating worked. There were "no new items" (which is curious and unbelievable), but at least ListeriaBot made a search. Did you try to update manually and see the result? Something has to be changed in any case! --Edelseider (talk) 07:43, 3 October 2020 (UTC)

Hans HammerEdit


Concerning the link between Hans and Friedrich Hammer, I know this source, but I don’t consider it reliable on this specific point, as it has many problems. It is rather vague and, at the contrary of some of their other affirmations, they don’t quote the origin of it. Besides, I’ve read nearly all the books they mention in the literature at the bottom of the page and none say that. More problematic, I have also read most of the research focused on Hans Hammer and I have neither come across this affirmation. It does mean that someone have eventually said that somewhere, but that the peers have preferred to not repeat it, implying they disagree, or at best that they are not convinced of this relation. As far as I know, the only descent that is widely accepted by researchers is Michel from his first wife Margreden ; Hans, Catharina and Anna, probably from an unknown second wife ; no child are known from his third marriage.

I think it would be better to stick on data with a scientific consensus, especially as this data is automatically relayed elsewhere (in Wikipedia infoboxes for example). We could still add it later if it finally gain more support from researchers : I monitor everything related to Hans Hammer and other late gothic architects, so if it appears in a paper in the future, there is high chances I will notice it.

Art catalogs versus booksEdit

Why do you feel an art catalog is not a book? Also, why is it important to specify that an art catalog is also a book? I understand merging a book with an exhibition and do this myself quite a bit, using instance of (P31) for two items, "art exhibition" and "art catalog". To additionally specify "book" seems excessive and also contradictory to the "art exhibition" part. Are you suggesting that in such cases there should always be at least two items for the book and for the exhibition? I don't see the added value for doing it this way. Jane023 (talk) 15:19, 18 January 2021 (UTC)

@Jane023: It is not about my feelings. When I enter the identifier P212 "ISBN", I also have to enter a P31 "book". That's how Wikidata is configured! :) --Edelseider (talk) 15:55, 18 January 2021 (UTC)
Fixed. I made art catalog into a publication and the constraint is gone. Jane023 (talk) 17:29, 18 January 2021 (UTC)
@Jane023: You lost no time. Good, and thanks! --Edelseider (talk) 17:31, 18 January 2021 (UTC)
