Hello, I would like to request feedback before creating a new Wikidata item for BlackSheep Fund, an Italian venture capital fund.

The fund appears to have received independent coverage over multiple years. Relevant sources include:

• Il Sole 24 Ore
• Financecommunity
• EconomyUp
• Engage.it
• Startupbusiness.it
• StartupItalia
• BeBeez

I have a connection to the subject, so I would like to disclose a potential conflict of interest and seek community input before proceeding.

My intention is to create a minimal, neutral, and well-sourced item, including only basic statements such as:

• instance of (venture capital fund)
• country (Italy)
• official website
• LinkedIn organization ID

At this stage, I would avoid adding promotional or non-essential information and focus only on verifiable data supported by independent sources.

As an additional note, the name “BlackSheep Ventures” is currently used in external communication as a broader brand reference. However, based on the available independent sources, “BlackSheep Fund” appears to be the most consistently attested name for the investment vehicle itself. For this reason, I am considering using “BlackSheep Fund” as the main label and potentially including “BlackSheep Ventures” as an alias, subject to community feedback.

I would appreciate feedback on:

1. whether the subject meets Wikidata’s notability criteria
2. whether “BlackSheep Fund” is the most appropriate and unambiguous label for the entity

Thank you in advance for your guidance. Marcicello (talk) 14:49, 19 March 2026 (UTC)Reply

Hello, just a quick follow-up. As there were no objections, I have created a minimal item for BlackSheep Fund based on the sources mentioned above.

Happy to adjust or improve it based on any feedback. Thanks! Marcicello (talk) 17:05, 26 March 2026 (UTC)Reply

You should have included this link: BlackSheep Fund (Q138795484) Bovlb (talk) 21:51, 31 March 2026 (UTC)Reply

Thanks for sharing the link, much appreciated.

How should I add islands like Jan Mayen, Nova Zembla and Spitsbergen to Arctic Ocean (Q788) ? - Erik Baas (talk) 15:37, 21 March 2026 (UTC)Reply

@Erik Baas I believe you should link the island with the ocean/sea using located in or next to body of water (P206) added to the island, see for example https://www.wikidata.org/wiki/Q14056#P206 Piecesofuk (talk) 10:48, 23 March 2026 (UTC)Reply

Thanks. But that was not my question... - Erik Baas (talk) 12:31, 24 March 2026 (UTC)Reply

I think it would be useful to know why you want to add the islands to the Arctic Ocean (Q788) item, instead of using a query to list the islands located in the ocean? --Ajarmund (talk) 00:03, 26 March 2026 (UTC)Reply

As far as I'm aware you don't add islands to oceans or seas but you add the sea to the island as I described above. There's a gadget available at https://www.wikidata.org/wiki/Special:Preferences#mw-prefsection-gadgets "relateditems: Adds a button to the bottom of item pages to display inverse statements" which adds a "show derived statements" link which will show you those islands Piecesofuk (talk) 07:36, 26 March 2026 (UTC)Reply

Tipula (Acutipula) longispina includes the subgenus (Acutipula) in the name. I suspect that this is a mistake. In Wikipedia article titles, a subgenus name normally is not included. I think the best solution is to change each instance of Tipula (Acutipula) longispina as a name in Q2655088 to Tipula longistila, and to add Tipula (Acutipula) longispina in the "Also known as" field. I am not a taxonomist, so I am asking what should be done before attempting to do it. Also, I created Tipula longistila (Tipula longistila (Q138756096)) when I couldn't find Tipula longistila. It should probably be merged into Tipula longispina (Q2655088) once the naming question is resolved. True-Crane-Fly (talk) 05:01, 22 March 2026 (UTC)Reply

I think they are different species, Tipula longispina and Tipula longistila, but T. longistila only has one search result (https://zenodo.org/records/19134903) and was only published recently so there are no identifiers. Peter James (talk) 15:19, 22 March 2026 (UTC)Reply

It may be better to take this to Wikidata:WikiProject Taxonomy. They'll likely be able to offer some best practices for handling subgenuses. — Huntster (t @ c) 15:45, 22 March 2026 (UTC)Reply

They're the same. The use or not of the subgenus name is strictly a convention i.e. to tell people that's where you place that species within the genus, but it is not actually a part of the name itself. It's not a middle initial or a differentiator. Circeus (talk) 23:30, 25 March 2026 (UTC)Reply

Hello,

Following up on a previous discussion (now archived) about sharepointdesigns [dot] com being blocked by the spam filter when trying to add P856 to Q138650701.

I have requests open on:

Just ask any administrator, but they may not have time to give you anything more than the QIDs. Items you created since April 2024 which have been deleted are: Q138133520 Danantara Steering Commitee organizational division in Danantara and Q138133509 Danantara Supervisory Board organizational division in Danantara. Both basically empty. Deletion reason says author request so you literally asked for it. :-) Infrastruktur (talk) 07:16, 26 March 2026 (UTC)Reply

Thank you for listing both of that and confirming my doubt! There might be some problem with my memory because I am remembering false things like nonexistent contributions... I probably have some things planned to do but didn't get to execute them yet FenyMufyd (talk) 16:25, 26 March 2026 (UTC)Reply

I am working on research methods and it seem there are several items refering to the same methods but using diffrent logics of categorisation (some double items notably coming from distinctions existing in the MeSH descriptor ID):

• Some items refer to the method (e.g. literature review (Q2412849))
• Some items refer to academic publications using the method (e.g. review article (Q7318358))
• Some items refer to the method as a research topic (e.g. scoping review (Q101116078))

I assume these dinstinctions exist because they are useful in a tree-structured database. But in wikidata we just need the first type of item because we can include in the academic publication item the property study type (P8363) to say the publication use the method and the property main subject (P921) to say that the paper is about the method.

So the question is: does it make sense to merge items such as twin study (Q131366935) and twin study (Q244775) even though they have different MeSH descriptor ID (P486) ? (As a researcher I would merge those items but maybe librarians have a different opinion on this?)

Jeanne Noiraud (talk) 18:06, 24 March 2026 (UTC)Reply

This is no different from painting (Q11629) and painting (Q3305213): the method and the result are different items. Not all twin study (Q244775) necessarily result in a publication. While sometimes a weird distinction seems to exist in a database that is not justified in Wikidata, here this is not the case. Circeus (talk) 13:44, 30 March 2026 (UTC)Reply

I was notified that one of my watched items had been linked to a new item, and discovered that there has been created at least 18 new items for people educated at (P69) Savitribai Phule Pune University (Q3135913) by new accounts with similar names. So they seem self-promotional without any external identifiers. For some reason, several of them end with "11" and have height (P2048) 5.5, and several have occupation (P106) set to phd theses or scientific papers (not occupations).

For examples, see https://w.wiki/KLUM ; e.g. Q138786137, Q138786060, Q138784502

This might be some sort of good-faith campaign, so I don't know what the best approach to them would be. Any thoughts? --Ajarmund (talk) 17:24, 25 March 2026 (UTC)Reply

Hello,

Could contributors please help improve item Kévin Boutillier (Q138660429): no description by adding key identifiers and basic biographical properties, with reliable references?

Suggested additions:

• first name
• family name
• date of birth
• occupation
• LOC ID
• IMDb ID
• GND ID
• ISNI ID
• Google Knowledge Graph ID

These identifiers appear to be available in structured data and could be added here if they match the same person and are properly sourced.

• IMDb : https://m.imdb.com/fr/name/nm18309421
• LOC : https://id.loc.gov/authorities/names/n2026510334
• GND : https://d-nb.info/gnd/138953653X
• ISNI : https://isni.org/isni/0000000529623882
• Google Knowledge Graph ID : https://www.google.com/search?kgmid=/g/11yp_5040h

Thank you. Vinke33 (talk) 10:35, 26 March 2026 (UTC)Reply

Thank you for completing the Wikidata profile @Trade

For the Google Knowledge Panel, the correct Google ID key is: /g/11yp_5040h.

The birth date is July 18, 1993, and this information is referenced in IMDb, GND, and LoC records.

Thank you very much for this valuable contribution. Vinke33 (talk) 09:43, 27 March 2026 (UTC)Reply

How is this person (is it you, or related to the CoI which you recently blanKed?) notable? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 19:45, 27 March 2026 (UTC)Reply

@Pigsonthewing: Thanks for asking.

Yes — I’m the same person as the subject of the item, and I’m stating that here for transparency.

On Wikidata, the record is supported by third-party authority and database identifiers (LoC, GND, ISNI, IMDb, etc.), with references. That’s the usual basis for maintaining a person item. I’m not claiming that I meet the threshold for a standalone Wikipedia biography; that’s a separate question and depends on independent secondary coverage.

I try to follow the same spirit as well-curated authority data (e.g. LoC, GND): statements should be verifiable and tied to reliable sources. For the item about myself, I avoid editing it directly to steer the content; I put requests to the community so updates can be reviewed on-wiki and it stays clear of self-promotion.

My aim is for statements to reflect what those sources already publish, not to promote myself. If anything looks unsupported, imprecise, or undue, I’m glad for others to correct or trim it.

About the blanking: it wasn’t an attempt to conceal anything — I had cleared text on my user page while tidying up.

I’m still fairly new and learning Wikimedia tools and norms day by day; I care about doing neat, well-sourced work. My background is in the semantic web, Schema.org, and AI, and I hope to contribute usefully in those areas over time. Please feel free to point me to policies, properties, or conventions I should follow, and to suggest anything that should be added to User:Vinke33 or related threads if that would help.

Thanks for your vigilance; it helps keep the data trustworthy.

• The previous CoI still exists, and should remain declared. If you don't want it on your user page, put it on the item's talk page.
  • Update: Item Q137441557 was deleted as promotional, so struck.
• You have a CoI regarding the item about yourself. Until you answered my question this does not appear to have been declared, and was not mentioned in your original post here.
• Several of the identifiers you list can be self-generated; and do not confer notability.
• Some of them may indicate notability, but this is not a given, especially if they just reflect the existence of user-generated IDs or profiles.
• Suggesting identifiers be used "if they match the same person" seems disingenuous, given that you are that person.
• You were advised in January, at Wikidata:Project chat/Archive/2026/01#Question about notability: Semantic web researcher with ORCID, LOV vocabularies, Schema.org contributions, and again this month at Wikidata:Bistro/Archive/2026/03#Demande de création d’un item Person pour Kévin Boutillier (identifiants d’autorité), that you did not meet our notability criteria.

Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 11:35, 29 March 2026 (UTC)Reply

Thank you again for your vigilance.

I aim to follow Wikidata:Notability, in particular criterion 2: the item should refer to a clearly identifiable conceptual or material entity that can be described using serious and publicly available references. National library authority records (GND, LoC, IdRef, and similar) are examples of such sources; they are not identifiers I can create for myself.

Regarding Verisav and the requests I routed through the community: this was my first experience with Wikidata, and I had not yet fully understood how the project works or the importance of declaring a conflict of interest up front. I will keep that in mind going forward.

Best regards, Vinke33 (talk) 12:44, 29 March 2026 (UTC)Reply

Following your note about keeping the conflict of interest visible: I have now added an explicit CoI statement on my user page, including that I do not edit statements on my own item myself and route changes through the community.

3-Methyl-2-pentanone (Q15720827) has type of chemical entity (Q113145171) as its value for instance of (P31). However, there are two stereoisomers of 3-methyl-2-pentanone, one being (R)-3-methyl-2-pentanone (CAS Number: 57968-72-6, PubChem: 6999802) and the other being (S)-3-methyl-2-pentanone (CAS Number: 2695-53-6, PubChem: 6994393). I searched the CAS Numbers of each of the stereoisomers in Wikidata, and could not find the pages for each stereoisomer, meaning that they may not have their own items.

Should 3-Methyl-2-pentanone (Q15720827) have group of stereoisomers (Q59199015) as its value for instance of (P31) instead of type of chemical entity (Q113145171)?

I began working on Raul Panther III (Q138792280) and Sir Dr. Robert Bakker (Q138791926) but I wasn't certain how to proceed, particularly when it comes to questions of whether they are instances of humans. Panther and Bakker are the stage personas of anonymous performers who cannot have their own Q item because they intentionally hide their real identities. Everyone in their band is "in universe" for their rock opera's narrative and many of those characters are robots, rather than humans. However it's easily apparent to anyone that these folks are human, and the robot thing is part of the performance. This was also causing me some confusion because Panther plays another character in universe: Joe (Q138792105). It was causing an error on Joe's item if I didn't list Panther as some kind of human. The man who plays Panther is human but fictionally it's not clear whether Panther the character is human. And the character Panther in universe performs as other characters like Joe.

Are there other Q items that have pinned down how this kind of performance stuff should be reflected on Wikidata? Thanks. Pingnova (talk) 21:45, 27 March 2026 (UTC)Reply

"anonymous performers who cannot have their own Q item because they intentionally hide their real identities"—Yes they can. Simply label them as "anonymous".

But are the two personas always related to the same two anonymous individuals? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 22:13, 27 March 2026 (UTC)Reply

So I make a new Q item called "anonymous" and fill out the real person's known information there, such as "human"? And then say that anonymous plays Panther? And then Panther plays Joe?

Yes, Panther and Bakker are always played by the same anonymous stage performers. Pingnova (talk) 01:27, 28 March 2026 (UTC)Reply

At Igor Klatzo (Q11711445) (and some other entries) I saw additional statements for date of birth (P569), which only contain the year of birth, while there is also a statement for the whole date. How is the policy about those? Can one remove them (apart from cases, where they are contradicting and should be marked as false)? Flominator (talk) 10:39, 28 March 2026 (UTC)Reply

If they're referenced then I would keep them and make sure the more accurate statement has a preferred rank. Not sure if there's any official policy regarding this though. Piecesofuk (talk) 11:00, 28 March 2026 (UTC)Reply

If either statement is unsourced, just remove it. Otherwise, make the more precise statement preferred (Help:Ranks). Optionally, qualify with reason for preferred rank (P7452): most precise value (Q71536040) to tell others why you did so.

If two (or more) statements are in contradiction, make all of them but one deprecated (Help:Ranks). Which one should not be deprecated is the most difficult question to answer. Alternatively, leave them as they are, it's quite common that sources disagree on someone's significant dates, and it's not purpose of Wikidata to establish the truth.

No official policy, WD:UCS applies. --Matěj Suchánek (talk) 08:56, 29 March 2026 (UTC)Reply

Hello, is it possible to automatically transfer the family relationships added to one object to another? Example: Elisabeth, Gräfin von Solms-Braunfels is the great-grandmother of Elizabeth of Isenburg (Q61139851), is it possible to somehow link the two objects without having to manually add to Elisabeth, Gräfin von Solms-Braunfels that Elizabeth of Isenburg (Q61139851) is her great-granddaughter?

@Dieda30: It is probably possible, but it not adviceable to do it that way. It is possible to get information about a persons relatives using SPARQL queries (by for example checking parents of parents and so on). That has the big advantage that you just need to add that someone was the parent/child of someone else once and the rest is automatic. Adding all relatives that you can find to any person in the database will make the database huge and very hard to maintain. Gunnar Larsson (talk) 09:35, 29 March 2026 (UTC)Reply

Hello, I'm trying to understand how to add a spouse to Marie Salmon (Q138507599). His name was Jean-Louis Savary (not Jean Louis Savary (Q59258498)). Don't I need to create a new wikidata entity for him, if I'm going to add him as a spouse?

"no value" means that there was no spouse. Use "unknown value" instead with an object named as (P1932) qualifier, see for example https://www.wikidata.org/wiki/Q335855#P26 However, since she has a Wikipedia article I would probably add the spouse as an item as I believe it would pass WDN3: "It fulfills a structural need, for example: it is needed to make statements made in other items more useful."

Since October 2021, Wikimedia Enterprise has offered services for high-volume commercial reusers of Wikimedia content. Over the past two years, Wikimedia Deutschland and Wikimedia Enterprise have collaborated during regular exchanges to explore how Wikidata’s data could be included in this service in a way that reflects our shared movement mission, values and responsibilities.

Wikimedia Enterprise is now announcing the beta release of its Wikidata APIs: read the announcement blog for more details on its technical features.

We want to share why we believe this decision is necessary in today’s context, what principles guide it, and which safeguards WMDE has put in place together with Wikimedia Enterprise to ensure we continue to work together toward our vision to freely share in the sum of all human knowledge for everyone?

Our main goal is to distribute knowledge as widely as possible.

Large, high-volume reusers play a major role in bringing Wikimedia content to people. Many of the tools, apps, and services that millions of people use every day depend on Wikimedia content. This has been true for years, long before an API designed specifically for the needs of commercial users existed.

Until now, these organizations have placed a significant technical burden on Wikimedia’s infrastructure — including server capacity, hardware, bandwidth, and the personnel required to run these services — all funded by donors who want to support Wikipedia and the Wikimedia projects. At the same time, they have been able to use this data at scale without offsetting the costs they generate. On top of that our infrastructure nowadays is under pressure in ways never seen before due to a significant rise in automated requests and scraping.

We believe it is reasonable and fair that companies that rely on Wikidata’s data and availability at a very large scale, and that profit from it, contribute to the cost of maintaining and improving this infrastructure. This is what has driven Enterprise’s principles https://meta.wikimedia.org/wiki/Wikimedia_Enterprise/Principles.

We are taking these steps to ensure that organizations that profit commercially in substantial ways are not doing so at the expense of the volunteers, donors, and infrastructure that make the Wikimedia projects possible.

The ideals of free and open knowledge arose in an earlier, more distributed internet, where power and access were shared among many actors, a landscape that has since changed significantly. Today, a small number of very large companies draw immense value from community-generated content and shape how knowledge flows online. If we want to protect the principles that have guided us since the beginning, we need updated models of stewarding the digital commons to match today’s realities. Asking heavy commercial beneficiaries to contribute financially is one way of upholding those values, not abandoning them.

Moreover, investments by enterprise customers benefit all reusers and will enable improvements such as improved documentation, higher reliability and new public-availability access methods and community-requested features that benefit Wikidata editors and reusers more broadly.

This direction is aligned with the Movement Strategy recommendations to:

• explore earned income through enterprise-grade APIs, and
• improve the Wikimedia API suite for all users.

We acknowledge that providing a commercially-focused service has raised concerns within our open-source and free knowledge communities. Below, we outline the major issues raised and how we are working with Wikimedia Enterprise to address them responsibly.

There are multiple ways to access Wikimedia Enterprise datasets for free, including through free accounts or Wikimedia Cloud Services (WMCS) and via third-party platforms. Free accounts are available to anyone, for any purpose, in line with Wikimedia’s licensing policies.

If you have a Wikimedia mission-aligned use case and your requirements exceed what is offered at no cost, you may request free access to a higher tier of the Enterprise APIs.

More details on all free access options, including how to apply for free access as a community member, are available here: https://meta.wikimedia.org/wiki/Wikimedia_Enterprise#Access

For cases that involve substantive use of Wikidata content, Wikimedia Deutschland is embedded in the review process for “exceptional access”  requests. Wikimedia Deutschland's input is given significant weight, and any disagreement on the interpretation of the exemption criteria triggers a good-faith joint review within Wikimedia Enterprise’s existing governance and review mechanisms.

We believe that Wikimedia Enterprise should improve access for everyone, not just paying customers. To support this, WMDE is working in close collaboration with Wikimedia Enterprise to emphasize work on:

• Better, centralized documentation for developers about all available APIs for Wikidata
• Documentation explaining how community developers can use Enterprise resources including clear information about authentication and available access paths through Wikimedia Cloud Services
• Jointly aligning on community-requested tools and services that benefit Wikidata editors and reusers more broadly (e.g. data integrity tooling such as the RevertRisk machine learning model).

Wikidata needs ongoing investment. As data and traffic grow, so do the costs of hosting, development and maintenance. All revenue generated through Wikimedia Enterprise is treated like any other unrestricted revenue received by the Wikimedia Foundation, which funds and hosts Wikidata and other Wikimedia projects. It flows into the Wikimedia Foundation’s general budget and is governed through the Foundation’s annual planning and budgeting process, with final oversight by the Board of Trustees. This is the same process used to allocate funds raised through donation campaigns and other fundraising efforts.

Revenue from large-scale enterprise use will support the infrastructure on which Wikidata depends, helping maintain stability and technical capacity for all users.

See the Wikimedia Enterprise FAQ and financial reports for details: https://meta.wikimedia.org/wiki/Wikimedia_Enterprise/FAQ#How_will_the_money_be_spent

https://diff.wikimedia.org/2025/11/24/wikimedia-enterprise-financial-report-fiscal-year-2024-2025/

We support including Wikidata’s data in Wikimedia Enterprise's APIs because we believe the future of free knowledge depends on equitable, sustainable infrastructure to enable broad, responsible reuse. By combining Wikidata’s community-curated, openly licensed knowledge graph with Wikimedia Enterprise’s focus on reliable distribution at scale, this collaboration helps ensure that the value created by volunteers reaches more people and systems worldwide.

Asking high-volume data reusers to contribute financially or through other means is a practical step to protect the work of volunteers, reduce strain on shared resources, and reinvest in the movement. Raja Amelung (WMDE) (talk) 15:00, 31 March 2026 (UTC)Reply

And if anyone has any questions/comments about the Enterprise API in general or this announcement specifically, you are also welcome to comment over on the project talkpage on meta wiki. LWyatt (WMF) (talk) 17:44, 31 March 2026 (UTC)Reply

Will a list of some of the customers become publically available for the sake of transparency? Trade (talk) 18:25, 31 March 2026 (UTC)Reply

Hello @Trade.

Yes - the most elaborate answer is on our FAQ page on Meta: "Who are the customers?". There's lots of links, context, history there.

But here's some info here too:

• We have many individual customers named in ‘long form’ case-studies. At that link - which goes to our project blog, filtered for the tag 'partners') you can see stories about Firecrawl, Mistral, Reef Media, Nomic AI, ProRata, Pleias, Ecosia...
• Also, ‘short form’ lists of customers in the annual financial report. The relevant paragraph of the most recent report - the 4th such annual report, stated:

Wikimedia Enterprise had 13 commercial customers utilising the paid tier of the service at the end of this financial reporting period. This includes single and multi-year contracts for either monetary or in-kind support, as well as organisations currently trialing the service. Also, there are many more individuals and organisations using the free tier.[...] Also, there are many more individuals and organisations using the free tier. New commercial contracts signed since June 30 and the publication of this report will be represented in the 2025-26 FY report.

It notes that the total commercial revenue at the end of the last fiscal year represented 4% of the WMF total, and that the project had now fully paid-back its startup investment costs and was profitable.

• Google was announced as the "launch customer" several years ago, but in the context of the 25th birthday this year, we also were able to announce Amazon, Meta (facebook), Microsoft and Perplexity.

Relatedly, the relevant policy governing this is the WMF "Wikimedia Foundation Commercial Sales and Contracts Policy". This formalises that there is exactly the same degree of governance and financial oversight for commercial customers as there is major philanthropic grants or donations (subsection: "Commercial Sales and Contracts Requiring Board Notice") - This includes a Human Rights assessment [see also the WMF "Gifts" policy]. Furthermore, that Commercial Sales and Contracts Policy states that we always always prefer to transparently report customers (Subsection "naming") but anonymity remains a right of all donors, grantors, and customers (just as this is also the case for readers, downloaders, and editors). Nevertheless, we will comprehensively report on the revenue received and expenses incurred, both within the normal WMF financial reports as well as separately (subsection: "Reporting"). You can see all those reports and other legal documents on the governance wiki.

I hope that thorougly answers the question. If you've got followups, I invite you to ask over on the Enterprise talkpage on Meta - to consolidate information there for the benefit of other future people with similar questions. LWyatt (WMF) (talk) 16:18, 1 April 2026 (UTC)Reply

A work of Linda Saul was indeed exhibited here which, as far as I am concerned, ensures notability by our standards. The user clearly has a COI and must be commended for coming here instead of just creating an item or paying an external company. Unless I hear objections reasonably soon, I will create an item (which might be tricky since I will leave for holidays in a few hours without my laptop, but I will find some way).

some people have "real" (aka official/formal) names in languages which are not their native languages, or they may not even be fluent in those languages. for example, many descendants of chinese may have a "chinese name", but they dont actually speak chinese, or this list of chinese names of sinologists https://home.uni-leipzig.de/clartp/ChineseNamesWesternScholars.html . what property do i use for this? none of Template:Name properties other than name (P2561) seems suitable. official name (P1448) and native label (P1705) cannot be used on humans. Kamala Harris (Q10853588) lists it as pseudonym. it's not a pseudonym (i.e. false name) but a real name for specific cultural contexts. RoyZuo (talk) 13:21, 1 April 2026 (UTC)Reply

TL;DR: Mobile editing now supports all datatypes (not just Strings and External IDs). Enable the beta feature in Preferences and test on any Item. Share feedback on the project talk page.

Hi everyone,

Following our earlier beta release for String and Entity ID datatypes, we're happy to announce that mobile statement editing now supports all datatypes. You can edit any statement directly from your mobile device, just like on desktop.

To try it out, make sure the beta feature is still enabled in your Preferences (Beta features --> "Edit Wikidata Items on mobile devices"). Then visit any Item on your mobile.

If you run into issues or have feedback, please share it on the project talk page: Mobile editing of statements.

Join our user testing panel and help improve mobile editing for everyone

We are planning new testing sessions from late April to early May. We're looking for volunteers of all experience levels, especially less experienced editors and users of RTL scripts (eg. Arabic, Hebrew, Persian, Urdu). Sessions are typically held via video call where you’ll try editing different datatypes and share your impressions with the team. Sign up (Great Question) to join the mobile testing panel, and we'll share details closer to the sessions.

Your feedback and participation are greatly appreciated.

Thanks. -Mohammed Abdulai (WMDE) (talk) 14:39, 1 April 2026 (UTC)Reply

On the English Wikipedia, "Organometallic compound" (Q2642710 on Wikidata) redirects to "Organometallic chemistry" (Q237200 on Wikidata), and Wikidata doesn't allow more than one item to be linked with a given Wikipedia article. When trying to merge Q2642710 to Q237200, I got an error indicating a conflict with links to non-English Wikipedia articles. Further complicating matters, Q2642710 was linked with "Metal-organic compound", which, according to the English Wikipedia, is a distinct concept from "Organometallic compound"; but see the talk pages for Q2642710 and for the English Wikipedia article about metal-organic compounds. However, Q2642710 is primarily about organometallic compounds, not metal-organic compounds. ZFT (talk) 22:03, 1 April 2026 (UTC)Reply

I think it would be better if this article from the French Wikipedia were connected to element Q6457851, as it deals with LGBTQ history in China, while this article would be better suited to element Q19514494, as it deals with LGBTQ rights. Questionadora ávida (talk) 00:28, 2 April 2026 (UTC)Reply
