Coordinates display in decimal [ edit ]

I prefer to add coordinates in decimal format and would like to see them in decimal rather than DMS format. Is there a gadget like thing that can help with this? Arjunaraoc ( talk ) 14:56, 15 May 2024 (UTC) [ reply ]

I'm not aware of one. If you want to write your own, I'd start by looking at Wikidata:Tools/Enhance_user_interface#Userscripts_to_enhance_the_display_of_values . Bovlb ( talk ) 15:19, 15 May 2024 (UTC) [ reply ]
Why is the default DMS? There is en:ISO 6709 . If I understand it right, they say: "Fraction of degrees (decimal degrees) is preferred in digital data exchange, while sexagesimal notation is tolerated for compatibility" . Please can we change the default? -- sk ( talk ) 09:29, 16 May 2024 (UTC) [ reply ]
Sexagesimal is easily divisible for humans. Coordinate notation in DMS is mostly historical at this point, made irrelevant by the advent of computers. And I still see coordinates presuming to be accurate to 10000th of a second on Wikidata, which is dubious seing as commercial GPS is accurate to between 1-10 meters. If mathematicians ruled the world we'd probably have coordinates based on radians instead. :P Infrastruktur ( talk ) 10:14, 16 May 2024 (UTC) [ reply ]
I'd vote to change the default to decimal. Its easier to mentally compare 2 numbers at the precision level I'm interested in, and copy the information out to other places. Vicarage ( talk ) 10:36, 16 May 2024 (UTC) [ reply ]
I support. Arjunaraoc ( talk ) 14:55, 16 May 2024 (UTC) [ reply ]
I would have no objection to switching to decimal. Bovlb ( talk ) 03:30, 17 May 2024 (UTC) [ reply ]
"digital data exchange" means things like APIs and file formats (things designed for computers to read). How it should be displayed for humans to read is a different matter, which that page covers in the section " Representation at the human interface (Annex D) ". - Nikki ( talk ) 15:13, 20 May 2024 (UTC) [ reply ]
@ Nikki , Thanks for providing the link, which helps clarify the current situation. I think a gadget is certainly required to add adding decimal display a, as it is more convenient and less error prone for humans also to work with. Arjunaraoc ( talk ) 00:35, 23 May 2024 (UTC) [ reply ]
Thanks to @ RamSeraph for implementing the request as part of his gadget . Arjunaraoc ( talk ) 08:34, 25 May 2024 (UTC) [ reply ]

Attribution text [ edit ]

At Halsted House (Q96358236) "attribution text" is giving an error. When I looked to see how it was used at another The Musicians (Q655705) it is used the same way with the same error message, any ideas? RAN ( talk ) 05:12, 22 May 2024 (UTC) [ reply ]

The property is designed for use on structured data on Commons and should not be used on Wikidata itself. Sjoerd de Bruin (talk) 07:34, 22 May 2024 (UTC) [ reply ]
+1, this property was not meant for that (as indicated on the constraint itself). I see that DaxServer did a big import using this property wrongly. I guess it should be removed (or moved, maybe as a qualifier of collection (P195) ??). Also ping Fuzheado . Cheers, VIGNERON ( talk ) 08:52, 22 May 2024 (UTC) [ reply ]

collection doesn't seem to have the attribution text, but has a donated by (P1028) . However, not all cases in the MET collection were donated with some being purchased. MET doesn't have that data categorized and just puts everything under " creditLine " DaxServer ( talk ) 09:27, 22 May 2024 (UTC) [ reply ]
@ DaxServer : Wikidata is about structured data so a text like "Gift of Henry U. and Emma B. Halsted, 1968" should be converted in the relevant provenance statements. That is not an easy task at all! Multichill ( talk ) 16:23, 24 May 2024 (UTC) [ reply ]
Now I understand why. Thanks again Multichill! DaxServer ( talk ) 17:25, 24 May 2024 (UTC) [ reply ]
  • @ DaxServer : Ah, now I get it. I have seen that error message before. Is there anyway the error message could be reworded to say "this property is to be used exclusively for structured data at Commons" instead of how it is currently worded? Is there a specific reason it is not allowed at Wikidata? Does it have to do with copyright of the attribution sentence? -- RAN ( talk ) 17:01, 22 May 2024 (UTC) [ reply ]

Scottish Index of Multiple Deprivation and similar deprivation indexes [ edit ]

Dear all

I was wondering if there is an existing mechanism in Wikidata for adding datasets connected to deprivation indexes, such as the Scottish Index of Multiple Deprivation (SIMD) and POLAR in England?

This data is currently available under a OGL3.0 and provides rich population-level data on access to healthcare, education, income levels, rurality etc. It is comprised of datazones that are ranked approximately every 4 years and are used heavily by Scottish Government and local authorities to decide on policy changes. It is currently available for 2012, 2016 and 2020, with the next one in 2026, in an XML format. More info about 2020, including the type of data that can be downloaded, are available here .


Any thoughts about whether it is suitable for adding to Wikidata, or whether it would be better as a standalone Wikibase would be deeply appreciated. Drkirstyross ( talk ) 10:58, 22 May 2024 (UTC) [ reply ]

I don't think in principle including them would be a problem, similar to any other demographic data, but there's a major practical issue: what items would we put these on? The published data zones are MSOA or similar, very small areas - and we don't tend to have items corresponding to those geographies. We'd have to duplicate that hierarchy and then tie them back into existing regions, which would be tricky. Andrew Gray ( talk ) 13:17, 22 May 2024 (UTC) [ reply ]
That's the tricky thing. Some areas are small (a couple of streets in some cases) but others are vast (those in the Highlands and Islands) as they are designed to encompass ~500 members of the population. Each datazone can contain multiple postcodes and/or council authorities. The ranking from each year is one thing, but it is made up of a plethora of measures that might be really useful additional information.
In the interests of transparency, I am hoping to combine various open population datasets as part of an undergraduate degree module I am coordinating in September 2023, so it would be amazing if the data were incorporated into Wikidata. It won't be the end of the world if it couldn't be done and/or done by then. Apologies, not really answering your question Andrew! Just wanted to start a conversation about it, as I imagine that there are similar governmental datasets available elsewhere. Drkirstyross ( talk ) 15:01, 22 May 2024 (UTC) [ reply ]
I think if you're adding more data to these that sounds fine - my concern would be that if we just had an item saying "this tiny bit of Cumbernauld has SIMD 7, and it's in Cumbernauld", there wouldn't really be much more you could do with it. I think ONS provide enough existing data to link them back up to the overlying areas?
It might be worth running up one or two examples and seeing what they look like. Andrew Gray ( talk ) 23:08, 23 May 2024 (UTC) [ reply ]

Q11639308 and Q56651571 [ edit ]

decommissioned (Q11639308) and out of service (Q56651571) are two terms used to describe the state of use (P5817) property. In my opinion, there is no difference between these items, so I propose to merge them. If this difference exists, just I don’t see it, please point out what it is, to make it possible to note this fact in the description of the items (especially in the case of out of service (Q56651571) , the description is now meaningless). I think the items also should have the different from (P1889) property added then (as in not in operation (Q111802839) ). Pyrlandczyk ( talk ) 08:19, 23 May 2024 (UTC) [ reply ]

I think something can fall out of use without being actively decommissioned ??Martin ( MSGJ ?·? talk ) 12:28, 23 May 2024 (UTC) [ reply ]
A mothballed power station can be out of service, but can return to service quite quickly. A decommissioned one normally has irrevocable changes. Vicarage ( talk ) 14:38, 23 May 2024 (UTC) [ reply ]
  • A vending machine can be temporarily "out of service" because it is empty or unplugged, but at the point where it is beyond repair it becomes "decommissioned". -- RAN ( talk ) 16:22, 23 May 2024 (UTC) [ reply ]

perpetrator of holocaust [ edit ]

Hi everyone,

the statement perpetrator of Holocaust is not added anywhere.

Here is the fitting SPARQL statement

SELECT DISTINCT ?item ?itemLabel WHERE {
SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE]". }
 {
   SELECT DISTINCT ?item WHERE {
     ?item p:P8031 ?statement0.
     ?statement0 (ps:P8031/(wdt:P279*)) wd:Q113546439.
   }
   LIMIT 100
 } 
 }

There is a Wikipedia category that lists those people. How do I go about batch adding those statements?

I can pipe together the various api's , but maybe there is a better way. also, if there is some kind of sandbox api endpoint, I'd be very interested as not to break anything.

Is this the right endpoint for adding a claim?


lastly, the Adolf Hitler entity is protected, so can an admin please ad purpotrator of holocaust to that enity?


best wishes. FerhatUnvar ( talk ) 08:29, 23 May 2024 (UTC) [ reply ]

The Holocaust (Q113546439) doesn't seem to be the correct item. I also think these kind of statements are too general. Sjoerd de Bruin (talk) 09:30, 23 May 2024 (UTC) [ reply ]
We don't have a "perpetrator of" property in Wikidata. Before you want to add anything in bulk, it would be good to understand how Wikidata works and that goes better if you add individual statements.
Q113546439 was just a doublicate that existed because nobody over at WikiBooks added it to the correct Wikidata item which is The Holocaust (Q2763) (you could easily find it by typing Holocaust into Wikipedia to see where that article is). That item actually has a statement that Hitler was a perpetrator of the Holocaust. That statement lacks citations and we have a constraint that citation are necessary for this property. ChristianKl ? ? ? 11:01, 23 May 2024 (UTC) [ reply ]
@ ChristianKl
That is confusing to me as I have built that query using Wikidata Query Builder , I was trusting that the autocomplete to give me correct suggestions. I assume you now added a redirect from Q113546439 to Q2763 , if so, cheers for that.
I was talking about the perpetrator property here and added "of" to make it a correct English sentence. I did add the perpetrator statement for Goebbels, so the linked statement now returns one result. I did look at the Wikipedia article for holocaust, but failed to find a reference to Q2763 or Wikidata on it, I see now it's hidden behind the "tool" dropdown. The citations constraint does not link a citation policy directly, adding a link to Help:Sources in the description seems like a good idea to me - or is there a more fitting page?. I am still unsure if linking a given person's Wikipedia article via imported from Wikimedia project (P143) meets the citation constraint. I suspect that there are a lot of wikipedia categories similar to Category:Holocaust_perpetrators that allow to infer statements, so implementing tooling to facilitate seem useful to me. My initial question is aimed if such tooling already exists and if not, how I can help in providing it. FerhatUnvar ( talk ) 12:16, 23 May 2024 (UTC) [ reply ]
Autocomplete is going to give you an item that matches the name that you are searching for. Wikidata does not yet process mind-reading techonology to know which item you actually want.
Help:Sources is unfortuantely no policy page and does not reflect current policy in regarding sources in Wikidata.
perpetrator (Q4445088) is an item and no property. The Holocaust did not perpetrate Joseph Gobbels, so the claim you added is wrong.
Claiming that someone is a Holocaust perpetrator is a quite serious charge and thus not something that shoudl be added simply because of a Wikipedia category but if such a claim would be added it should have a proper source. ChristianKl ? ? ? 12:37, 23 May 2024 (UTC) [ reply ]
Autocomplete is going to give you an item that matches the name that you are searching for. Wikidata does not yet process mind-reading techonology to know which item you actually want.
sometimes it is better just to say nothing if you have nothing constructive to say. Just feedback as you are part of the welcome new user initiative. You made me stop contributing all together.
FerhatUnvar ( talk ) 13:18, 23 May 2024 (UTC) [ reply ]
I explicitely told you that we have no "perpetrator of" property and you still assumed that another property does what you want a "perpetrator of" property to do. If you contribute on the basis of adding a lot of wrong statements to Wikidata because you don't engage in effort to understand what you are doing, that's bad for Wikidata and that's why I was as explicit as I was. ChristianKl ? ? ? 23:33, 23 May 2024 (UTC) [ reply ]
P143 is not adequate as a source for statements which are covered by the Living people policy which was mostly written by ChristianKl by the way. Sources for things like perpetrator are mandatory for living people or recently deceased. There might be people alive that was involved in the Holocaust. It would be a really bad idea to add such statements unsourced in batch. Infrastruktur ( talk ) 15:37, 23 May 2024 (UTC) [ reply ]
Relating to this I'd like to point out that we are using subject has role (P2868) for pointing people that are Holocaust victim (Q5883980) on over 128000 items. Maybe P2868 could be used for Holocaust perpetrators as well if there aren't more suitable properties? ? Samoasambia ? 11:37, 23 May 2024 (UTC) [ reply ]
That usage is already a bad attempt to circumvent our decisions about property creation. Using it for perpetrators would however even worse because mistaken claims about victims are not as serious as mistaken claims about perpetrators. ChristianKl ? ? ? 12:39, 23 May 2024 (UTC) [ reply ]
I want to add statements that X was/is a perpetrator of the Holocaust, where X is a person. The Holocaust is well researched, so sources are not a problem.
Could anyone kindly point me to resources so I can add those statements in bulk (with sources) via the API? FerhatUnvar ( talk ) 17:59, 24 May 2024 (UTC) [ reply ]
You can look at comparable items and check how they do it, for example, Osama bin Laden (Q1317) : significant event (P793) , Khalid Sheikh Mohammed (Q319068) : nothing, Hamza al-Ghamdi (Q653287) }: nothing, Mohamed Atta (Q110067) : participant in (P1344) etc.
Property participant in (P1344) looks like a good candidate to me. Difool ( talk ) 02:00, 25 May 2024 (UTC) [ reply ]
the holocaust Q2763 has the P8031 perpetrator property with the Value Adolf Hitler. When I understand the definition of P8031
it should be the statement Hitler participant in (P1344) Holocaust and participant should have qualifier "object has role perpetrator" and that claim should have a citation FerhatUnvar ( talk ) 05:31, 25 May 2024 (UTC) [ reply ]

Still objecting mass-adding statements like this without proper sourcing. Sjoerd de Bruin (talk) 08:47, 25 May 2024 (UTC) [ reply ]
Yes, I would call it a requirement, but I assumed the statements would be added with sources after reading "sources are not a problem" above. Difool ( talk ) 09:28, 25 May 2024 (UTC) [ reply ]
@ Sjoerddebruin I plan add sources as @ Difool suspected. I also want to follow all rules and requirements. That's the whole reason I am writing here instead of just doing it. I don't see a reason to repeatedly do the same manual steps if I can write a script once, create a table containing person ids and sources , to then finally run the script. FerhatUnvar ( talk ) 11:33, 25 May 2024 (UTC) [ reply ]
Thank you @ Difoolfor the query, but what I am looking for would be an insert statement/api call.
There are several people that perpetrated the holocaust but never were convicted. Also, holocaust is not a criminal charge. I could however add the charges from the Nuremberg trials. FerhatUnvar ( talk ) 11:38, 25 May 2024 (UTC) [ reply ]
It's not trivial to decide who was a perpetrator of the Holocaust. Were the perpetrators only those people who actively killed Jews? Those who helped to kill them? Those who commanded killing them? Or everybody who was a member of the Nazi Party? You definitely need a good source to add such statements. What soure are you planning to use? D3rT!m ( talk ) 11:51, 25 May 2024 (UTC) [ reply ]
I will add undisputed perpetrators. This is not a fact finding commission. I will follow the guidelines that apply to Wikipedia, meaning to stick to the scientific consensus and sources that satisfy academic criteria. FerhatUnvar ( talk ) 12:13, 25 May 2024 (UTC) [ reply ]
Wikidata items don't do well with having thousands of claims of the same type.
The best way to add perpetrators would be to create new items like "killing of Jewish people in Ausschwitz" with:
"killing of Jewish people in Ausschwitz" part of (P361) The Holocaust in Germany (Q3188158)
"killing of Jewish people in Ausschwitz" perpetrator (P8031) person-who-did-bad-thing ChristianKl ? ? ? 10:19, 27 May 2024 (UTC) [ reply ]

When it comes to sex or gender (P21) each item usually has only one value. In a complex case with a person who transitioned a few times, you might have a handful of sex or gender (P21) claims but never a thousand for a single person. ChristianKl ? ? ? 22:20, 27 May 2024 (UTC) [ reply ]
@ FerhatUnvar You can use the query to see how the statements are used, i.e. not a lot, and mostly for murders. I would use QuickStatements to add the statements. Difool ( talk ) 12:22, 25 May 2024 (UTC) [ reply ]

Conflation [ edit ]

I can't speak for every infobox on every project, but generally they should only be using " truthy " statements, so deprecating the claim will make it not used.

usage on other wikis [ edit ]

1. What needs to happen so each Wikidata item lists "usage on other wikis", like is routine on Wikimedia Commons?

  • On a few occasions, Wikidata administrators have tried to delete Wikidata items that I've created. If those items are not used on other Wikis AND if they have few properties and no links from other Wikidata items, that may be okay. However, I currently don't know how to get that information. The "what links here" feature within Wikidata identifies other uses within Wikidata but not from other Wikimedia Foundation projects.

2. What needs to happen so w:Template:Cite Q displays more than just the QID?

  • I've been challenged this past month by two other users on Wikipedia who did NOT like my use of w:Template:Cite Q in new articles I've created on Wikipedia. The first challenger replaced several of my w:Template:Cite Q references with the more traditional w:Template:Citation style. I complained, and the other user grudgingly allowed me to continue using Wikidata citations.
  • To make it easy to understand a QID, I've been including comments, e.g., <!-- Lewis Diuguid (2004) A Teacher’s Cry: Expose the Truth About Education Today-->{{cite Q|Q126074936}}.
  • I believe that meta:WikiCite would be much better received if {{cite Q|Q126074936}} could be understood without a comment expanding that QID into a text description, like I just did with the comment in this example.

3. What needs to happen so Wikipedians who are "watching" an article that has a Wikidata infobox ({{infobox .../Wikidata}}) could get a useful notice when the relevant Wikidata item changes?

  • I think I first became aware of Wikidata via emails that Wikipedia articles I was "watching" changed, and I could NOT see what had changed. Eventually, I learned that a Wikidata item used in an infobox had changed. That was several years ago. I have not seen that recently, but I wonder if it's still an issue that pushes many Wikimedians away from Wikidata?

FYI, I've logged over 22,000 edits in Wikidata since 2018 and over 15,000 in other WMF projects since 2010. DavidMCEddy ( talk ) 19:08, 25 May 2024 (UTC) [ reply ]

1) There are multiple issues here. Page Information does contain information about Wikidata items being used on other Wikimedia projects.
The deletion interface does warn about usages within Wikidata but does not warn about usages by other projects. Lastly, our notability rules do not result in "Cite Q" making an item notable.
3) There's the option "Show Wikidata edits in your watchlist" in Watchlist preferences over at Wikipedia. The problem is that a lot of changes to Wikidata items are of no interest to Wikipedia users. If there's another external ID property added that does not affect Wikipedia it still shows up in the watchlist and thus Wikipedians generally don't have "Show Wikidata edits in your watchlist" on.

2. I'm assuming Cite-Q will display the QID if there is no label available for the wiki's language. The fix is then to add a localized label.
I like Cite-Q myself and have been using it extensively on select Covid-19 articles. Adding comments defeats the purpose of using Cite-Q, I would recommend turning the reference into a named reference instead e.g. <ref name="roentgen1895">{{Cite Q|Q54525969}}</ref> Infrastruktur ( talk ) 21:01, 25 May 2024 (UTC) [ reply ]
When it comes to QID being displayed instead of labels I hope it will get soon better with mul. Does names of articles and names of people should be in mul and then be displayed in any language. ChristianKl ? ? ? 11:27, 26 May 2024 (UTC) [ reply ]
There does seem to be a language fallback already. I don't know the specifics of it but it would seem if a journal, book or paper specifies language of work or name (P407) then Cite-Q will fall back to using labels in that language if there is no native labels. If you need specifics it might be easier to ping Mike Peel or Pigsonthewing. It's very likely mul support will be implemented too. Infrastruktur ( talk ) 16:59, 26 May 2024 (UTC) [ reply ]

This item should probably be merged into material (Q214609) , however the interwiki links conflict. Someone speaking Zulu should verify this. It is possible the former entity and its only associated Wikipedia article are vandalism, they were created from a disruptive IP range. Janhrach ( talk ) 09:26, 26 May 2024 (UTC) [ reply ]

According to ChatGPT : "In Zulu, "Isithako" is more commonly used to refer to ingredients or components, especially in the context of cooking or making something that involves combining different substances. On the other hand, "I-Material," borrowed from English, is often used in more technical or industrial contexts to refer to raw materials or substances from which products are made."
For it to be merged, ZuluWiki would need to merge their pages. You would need to ask over at ZuluWiki to request them to merge their pages which they might or might not do. ChristianKl ? ? ? 10:31, 26 May 2024 (UTC) [ reply ]

Dealing with vandalism on translated pages [ edit ]

Discovered I can't simply rollback vandalism on translated pages.

Permission error

You do not have permission to quickly rollback the edits of the last user who edited a particular page, for the following reason:

This page cannot be updated manually. This page is a translation of the page Wikidata:Introduction and the translation can be updated using the translation tool.

Do I seriously have to undo every single one by hand or is there a better way? Infrastruktur ( talk ) 16:08, 26 May 2024 (UTC) [ reply ]

You need to find the edit in the Translation: namespace and undo that (or delete it, if the page was previously untranslated and the vandal edit created the translation). If the vandalism is coming from a single user, it would be a matter of filtering their contributions by namespace and doing mass rollback or mass delete. ?

Hello, there are always unconnected (new) articles in every language version, which need to be connected to existing wikidata items (if existing) or connected to a newly created item (if not yet existing):

Also, the AutosuggestSitelink -Gadget might be usefull for this purpose. It opens a wiki pop-up (not a browser pop-up), so articles, which are not yet connected to a wikidata object can be connected to an object (see screenshot). M2k~dewiki ( talk ) 15:08, 27 May 2024 (UTC) [ reply ]

Building complex vs architectural ensemble vs group of buildings [ edit ]

currently building complex (Q1497364) is a subclass of (P279) architectural ensemble (Q1497375) which is a subclass of (P279) of group of structures or buildings (Q18247357) which explicitly says "architectural structures or buildings that do not form a building complex, but are treated as a group"

I agree building complex (Q1497364) and group of structures or buildings (Q18247357) should be alternatives, expressing the tightness of the link between structures. architectural ensemble (Q1497375) is rather wooly, but because of that should probably be the parent for both. My interest is separating between buildings at a particular point, and ones spread across a larger area. Vicarage ( talk ) 10:38, 27 May 2024 (UTC) [ reply ]

Wikidata weekly summary #629 [ edit ]

A systematic approach to conditional statements [ edit ]

Some statements are only correct under certain conditions, and we have several restrictive qualifier (Q61719275) properties to express some common and generic types of such conditions ( list ). However, many statements would require more specific ways to express conditionality, and I do not think we would want to always create dedicated properties for them. Instead, we might want to give some thought to more generic ways of expressing conditionality.

To give an example where I could not find a way to express conditionality using existing Wikidata statements: A square pyramid (Q1075704) can only be considered a Johnson solid (Q1059659) if each and every one of the triangular faces of the square pyramid (Q1075704) is a equilateral triangle (Q157002) . A square pyramid (Q1075704) meeting this particular condition would then be a square pyramid with equilateral triangle sides (Q17370383) , which will always be a Johnson solid (Q1059659) . How can we express that statements like square pyramid (Q1075704) subclass of (P279) Johnson solid (Q1059659) are only true for a given ?qid if ?qid ( instance of (P31) or subclass of (P279) ) square pyramid with equilateral triangle sides (Q17370383) ?

Should we think here about generic properties like "has condition" or "applies under condition" or so, or should we perhaps try to be even more generic by looking into frameworks like the SuperPattern Ontology (Q111972233) ? Or would the current approach of creating dedicated properties indeed be preferable? Daniel Mietchen ( talk ) 16:18, 27 May 2024 (UTC) [ reply ]

First the pyramide a base carree et cotes equilateraux (Q17370383) is both a subclass of solide de Johnson (Q1059659) and pyramide a base carree (Q1075704) , so it meets both conditions
This would mean that it both satisfies the conditions of the definitions of a Johnson solid (Q1059659) and a square pyramid (Q1075704)
Maybe this would miss the "these are the "only" solid that meets both". This might be expressible with disjoint union of (P2738) View with SQID but maybe not simply. I think
would express this uniqueness. But we still would have to define negatively "square pyramid with non equilateral triangle" which could be done in this particular case by does not have part (P3113)

I'd just have paired disambiguations between concrete items here, if they could be confused under our name/description system. WP disambiguation pages reflect the constraints of their no-duplicate name systems, and are of limited used as a second-level connection between items.

P31 for firms and companies [ edit ]

For humans, we have a simple rule. P31 should always be human (Q5) . This makes it very easy.

For organizations, the approach is much more complex. We can have a lot of values:

Is there any discussion about using one value for all organisations? I would propose to use organization (Q43229) . PAC2 ( talk ) 20:18, 28 May 2024 (UTC) [ reply ]

Wikidata Infobox image [ edit ]

Hi. At Category:Megan Compain over at Commons, the Wikidata Infobox image is showing as this image but the wikidata image for Megan Compain is this image .

Re: New EntitySchema data type is ready for testing on Test Wikidata [ edit ]

Hello,

You may recall our previous announcement inviting you to test a new EntitySchema datatype on Test Wikidata . Once fully implemented, this data type will allow editors to refer to existing EntitySchemas in statements to indicate what class of Items are governed by an EntitySchema for example. Many thanks to everyone who provided feedback during the initial testing phase.

Based on your input, we have reassessed the architecture of the datatype. It should now return as a ‘wikibase-entityid’ when accessed through the API. See phab:T339920 for more information on this.

In addition to this update, we have made the following improvements:

  • Improved Display : EntitySchemas linked in statements, Wikitext, edit summaries and Special Pages are now displayed by their labels instead of their IDs, making them more readable and easier to understand.
  • Language Support : We've added support for language fallback to ensure EntitySchemas are legible across different languages.

We invite you to test these changes once again and provide us with your feedback by June 6 . Unless any major issues arise, we will enable the new datatype on Wikidata during the next train deployment. Once this is done, the open property proposal at Wikidata:Property_proposal/Pending#Shape_Expression_for_class can be created.

Please note when testing: the data type still needs to be registered with Wikibase Client to ensure full accessibility of Items with EntitySchema statements on client wikis. See phab:T363153 for more information on this.

If you encounter any issues, have questions or concerns, or want to provide feedback, please don’t hesitate to reach out to us on Wikidata talk:Schemas or leave a comment on this ticket ( phab:T332157 ).

Using Wikidata as an upstream for device information [ edit ]

As part of postmarketOS we track a significant amount of information about the specs of computer hardware, mostly tablets and phones (e.g. the OnePlus 6 ) . However, since this info is fixed, I've been thinking it probably makes more sense to find a more central datastore and put this info there and to pull from it instead. Found that some of our devices are already in Wikidata. We'd want to add some more fields probably, but a bunch would already be usable for us. Does this seem like a good use of Wikidata? 2A02:168:F912:0:0:0:0:1001 19:42, 29 May 2024 (UTC) [ reply ]

It could be a good use case. The main problem though is that we require information to have references (or at least be referenceable). I'm not clear on where your information is sourced to. Also it would depend on exactly how many new properties you would want made. You may want to consider using https://www.wikibase.cloud/ which I believe would let you federate somehow with wikidata while maintaining your own database separate from wikidata (which you could link bidirectionally to wikidata). If you went that route you wouldn't need to follow our rules about sources or notability. BrokenSegue ( talk ) 01:07, 30 May 2024 (UTC) [ reply ]
