OLAC Video Game Genre Vocabulary (Q60440967)Edit


Thank you for your changes on OLAC Video Game Genre Vocabulary (Q60440967).

I noticed you had added - instance of (P31) thesaurus (Q17152639).

Since thesaurus (Q17152639) subclass of (P279) controlled vocabulary (Q1469824), I had then removed - instance of (P31) controlled vocabulary (Q1469824): it would not be necessary to have both values as instance of (P31) − this is implicit per the subclass of (P279) relationship.

Unless is it wrong to have thesaurus (Q17152639) subclass of (P279) controlled vocabulary (Q1469824)?

Cheers, Jean-Fred (talk) 09:29, 16 June 2020 (UTC)


Hi! Please note that Q-items on Wikidata are about concepts, not words. Hence different items should be created for different concepts denoted by the same word. Data about words can be entered as Wikidata:Lexicographical data in "Lexeme" namespace instead. 2001:7D0:81F7:B580:D996:CF7C:6B2B:63C0 08:06, 22 September 2020 (UTC)

Also, please don't mix ethnic group and nationality (or sum of all residents of a country). E.g. Estonians (Q173302) (ethnic group) and citizens (or residents) of Estonia are entirely different groups of people. If in some relation it becomes useful, and it isn't enough to say that e.g. an individual is a citizen of Estonia or alike, then rather separate item should be created for Estonians or residents or citizens of Estonia, too. 2001:7D0:81F7:B580:F519:F3B5:A49:8293 09:46, 16 November 2020 (UTC)

orientalist (Q1731155)Edit

Hello, please do not merge into the newest item. Thanks. Ayack (talk) 08:27, 10 October 2020 (UTC)

Wood chemistryEdit

Hello, you asked me of me removing YSO ID from the item wood chemistry (Q25451366). I am one of the maintainers of YSO at National Library of Finland. YSO is a trilingual vocabulary (Finnish, Swedish, English). wood chemistry (Q25451366) is/was an item with no links to Wikipedia. On the other hand, there were two items, Q31886986 (Swedish: träkemi) and Q99196245 (Finnish: puukemia), with identical meanings that both had one Wikipedia article link to Swedish Träkemi and Finnish Puukemia respectively. As you say, "wood chemistry" is indeed "puukemia" in Finnish. On the other hand, in Swedish "wood chemistry" is called "träkemi". Thus there were separate items in all these three languages (English, Finnish, Swedish) when there should have been only one. I merged all the three items into one and linked YSO with the remaining item. I've been instructed by Wikimedia Finland that a) it is safest to link to the remaining item and not the one(s) that have been merged with it and b) it is best to keep the oldest item while merging. I followed these instructions. Tpalonen (talk) 11:20, 2 December 2020 (UTC)

  • Thank you for the explanation and for the merging of the three items. I believe that the labels should all be in lowercase per Wikidata policy. See comments below under "Label and case" and Help:Label#Capitalization. UWashPrincipalCataloger (talk) 11:47, 2 December 2020 (UTC)
  • Thank you for your reply! And thank you for bringing up the lowercase issue. It is indeed quite common for the Finnish labels in Wikidata to have an upper case initial. My theory for this is that many of them may have been generated from the Finnish Wikipedia article topic. Tpalonen (talk) 12:00, 2 December 2020 (UTC)

Adding YSO ID's to itemsEdit

Hello, I'm an information specialist working at National Library of Finland's Finto service where we are linking General Finnish Ontology (YSO) concepts to Wikidata items at the moment. As you may know, YSO is an indexing tool used widely in the Finnish library sector as well as in museums, archives, public administration and media. I noticed that you have added YSO id's to Wikidata items. While we appreciate your kindess, we would also like to remind that YSO concepts are maintained by a team of information specialists and are a result of careful concept analysis. Each concept has a specific meaning, indicated foremost by its Finnish and Swedish preferred terms and its broader concepts in the ontology hierarchy, but also, in practical terms, by its use in indexing of Finnish non-fiction literature and other domains. Any links made should be in accordance with the precise meaning of the concept. Therefore, while we are happy to receive help, we also express that anybody who's willing to help us in linking YSO concepts to Wikidata should have excellent skills in Finnish and Swedish and should follow the guidelines given by National Library of Finland (for example, see our guidelines for linking YSO to LCSH in the link, all of these won't apply to Wikidata, however, as we are only using SKOS:closeMatch with Wikidata as opposed to closeMatch/narrowMatch/broadMatch in the case of LCSH: https://www.kiwi.fi/display/Finto/YSOn+LCSH-linkitysten+linjaukset). For example, online translation tools such as Google Translate are not a good enough source for judging the equivalence of a Wikipedia item and a YSO concept. If you are interested in helping us more, please contact us. See our contact info here: https://www.kansalliskirjasto.fi/en/services/system-platform-services/finto Thank you! Tpalonen (talk) 11:38, 2 December 2020 (UTC)

Label and caseEdit


Unlike Wikipedia articles title, the label on Wikidata is not a title ; that's why the case is different (and that's why I changed ~5000 labels today, like I do every months for years now). See Help:Label#Capitalization for more details.

Cheers, VIGNERON (talk) 19:48, 31 October 2020 (UTC)

  • Hi, Thanks for pointing me to the Capitalization guidelines! UWashPrincipalCataloger (talk) 19:50, 31 October 2020 (UTC)
    • No problem, it's indeed a bit counter-intuitive. Don't hesitate to ask if there is any question or comment. Cheers, VIGNERON (talk) 22:00, 31 October 2020 (UTC)

Filiberto Barajas-López (Q101012047)Edit

Thanks for adding Library of Congress authority ID (P244) ! Did this exist at the time I created the item? I must have forgotten to look... Riesengrey (talk) 23:04, 12 November 2020 (UTC)

  • No, it didn't exist when you created the item, so you didn't forget anything. I created the NAR for him when I noticed that the name in OCLC wasn't controlled. UWashPrincipalCataloger (talk) 23:32, 12 November 2020 (UTC)

nature conservationEdit

You moved many articles from Conservation (Q628403) to nature conservation (Q20113959). I do not understand what the difference of the subject of these items is and what your criteria for having articles liked one or the other item is. Could you explain this? --GPSLeo (talk) 12:34, 13 January 2021 (UTC)

Conservation is a broader concept than Nature conservation. Conservation includes energy resources, mineral resources, agriculture, water resources, etc. The links I moved are for nature conservation specifically (https://en.wikipedia.org/wiki/Nature_conservation), which should be linked to the Wikidata item for nature conservation, not the more general item on conservation. I left the Wikipedia links that are broader on the item for conservation. See also https://en.wikipedia.org/wiki/Conservation, which discusses the differences of types of conservation. UWashPrincipalCataloger (talk) 18:32, 13 January 2021 (UTC)
I understand the difference but then I do not see the difference to environmental protection (Q832237). Another problem Conservation (Q628403) has the statement instance of (P31) branch of biology (Q28598684) with the new definition this statement would be false. But I also think things you wrote as included in Conservation but not in nature conservation are included in nature conservation. The enwiki has "enhancing ecosystem services" as part of nature conservation and the definition in dewiki has, based on the German law, the protection of artificial landscapes like agricultural landscapes as part of nature conservation. --GPSLeo (talk) 19:27, 13 January 2021 (UTC)
As I understand it, environmental protection (Q832237) would cover things like air and water quality, soil pollution, protection from hazardous wastes, etc., none of which would be considered part of nature conservation. I fixed the relationship problem that you mentioned. I'm also fixing labels so that they are on the right item. And I'm adding more identifiers to the nature conservation and related items. UWashPrincipalCataloger (talk) 20:22, 13 January 2021 (UTC)

Two VIAFEdit

Hi Adam. The script for adding identifiers works pretty cool. Thanks for suggesting that. It saves a lot of time. I wanted to ask you one question. What should we do if the person has two different VIAF pages ? --Gazal world (talk) 18:10, 15 January 2021 (UTC)

Hi, the best thing to do is to report the duplicates to OCLC. There's "feedback" link on each VIAF page that you can use. You can also put both IDs into the item for now. --Adam UWashPrincipalCataloger (talk) 18:24, 15 January 2021 (UTC)

Ok. Got it. I will do as you suggested. One more question ? How to add identifiers for books? For example this book. --Gazal world (talk) 14:10, 16 January 2021 (UTC)
See https://www.wikidata.org/wiki/Wikidata:WikiProject_Books. The type of identifiers you can add depends on what the item represents. There should be one item for the work, and then separate items for any editions of the work. ISBNs can only go on edition items. The WikiProject Books page explains everything. Lord and Peasant in Russia: From the Ninth to the Nineteenth Century (Q104844726) appears to represent the work, since it is the only item for this work. On this record you can add the properties for work found at https://www.wikidata.org/wiki/Wikidata:WikiProject_Books#Work_item_properties. Then you can create separate items for specific editions of the work by following https://www.wikidata.org/wiki/Wikidata:WikiProject_Books#Edition_item_properties. Here's an example that I did recently: Tacoma Stories (Q104593306) and Tacoma Stories (First edition) (Q104594562). UWashPrincipalCataloger (talk) 23:52, 16 January 2021 (UTC)

Your modificationEdit

Hello UWashPrincipalCataloger, Your modification doesn't suit a property. Cordially. —Eihel (talk) 07:12, 29 January 2021 (UTC)

wrong LCCN entriesEdit

Hi, since you are a professional librarian from the US, I though I might ask you: Is there any way to have faulty LCCN entries (like conflations) corrected? I know nobody who managed to contact the LC in any way … --Emu (talk) 11:12, 2 February 2021 (UTC)

Hi Emu, probably the simplest way would be to contact LC at coop@loc.gov to report a problem with an LCCN that represents more than one person. Or contact a NACO library from the directory at https://www.loc.gov/aba/pcc/naco/contact.html. UWashPrincipalCataloger (talk) 18:52, 2 February 2021 (UTC)

Your edit at RfDEdit

Hi, you removed Deletion requests with your recent edit at WD:RfD. If that happened on purpose, can you provide an explanation; If it didn't happen on purpose, can you please undo it and make sure that it doesn't happen again? Thank you -- Dr.üsenfieber (talk) 12:17, 16 February 2021 (UTC)

I did not intentionally remove any requests, and I am baffled about this. The only thing that I did on this page yesterday was to add a vote to keep Q54800218. I am unclear what exactly needs to be undone. UWashPrincipalCataloger (talk) 17:11, 16 February 2021 (UTC)

url farm on Q102047184Edit

Hi UWashPrincipalCataloger,

Somehow your approach on Q102047184 seems to go in the opposite way this is generally done: rather than determine the topic of an article and create an item for it, you added a set of identifier urls on the item of the topic. Besides, it isn't consistent with the purpose of described at URL (P973). Maybe you want to seek input on project chat on how to model this in general. --- Jura 00:21, 17 February 2021 (UTC)

I think you are misinterpreting the purpose of described at URL (P973). It is used to point to web sources that are about the item, not to the full text of the article that is represented by the item. described at URL (P973) is a subject link to sources on the web that describe the concept in the item. For an article item, the full text of the article isn't about the article, it is the article. I will follow up on project chat. UWashPrincipalCataloger (talk) 00:26, 17 February 2021 (UTC)

  • Two of the articles didn't have "main subject" link to the topic, I added it. @UWashPrincipalCataloger: I think @Jura1: is right: there are millions of articles that have "main subject" links to topics. The topics don't have links "described by source" to all those articles because there could be hundreds of thousands of articles about the same topic.
    • But if you're pretty sure these are the best 4 articles about that topic, then the "described by source" links can stay --Vladimir Alexiev (talk) 08:42, 7 December 2021 (UTC)
    I can't say that these are the best 4 articles, but I don't see anything in the property that requires this. I interpret the property as being used to link to items for useful sources that describe the topic. UWashPrincipalCataloger (talk) 20:37, 7 December 2021 (UTC)

Problematic property creationEdit

Hi UWashPrincipalCataloger,

If you create properties, please create them as proposed. DO NOT substantially alter them as done at [1]. If you think the proposal needs to be improved before creation, please participate in the discussion instead. "Polishing" them is fine (see Wikidata:Property_creators#Create_the_property). --- Jura 09:20, 28 February 2021 (UTC)

@Jura1: noted, thanks. UWashPrincipalCataloger (talk) 19:59, 28 February 2021 (UTC)

Unreferenced claimEdit

Hi UWashPrincipalCataloger

At [2], you added a claim about ethnic groups to Wikidata. Can you add a reference to this? You might want to have a look at w:Demographics_of_Zambia#Ethnic_groups.

On a related matter, please note that ethnic group (P172) has specific referencing requirements. --- Jura 07:13, 9 March 2021 (UTC)

  • Hi Jura1, ethnic group (Q41710) is defined as "socially defined category of people who identify with each other", and the Wikipedia article says it is a "grouping of people who identify with each other on the basis of shared attributes that distinguish them from other groups such as a common set of traditions, ancestry, language, history, society, culture, nation, religion, or social treatment within their residing area. Ethnicity is sometimes used interchangeably with the term nation ...", so on the basis of being a socially defined category based on being a nation, it seems that calling Zambians an ethnic group is acceptable. Nearly every item for the people of a country have a statement that they are an instance of an ethnic group. I've added a few sources that I hope are acceptable. In particular, the first, http://www.zambiapretoria.net/demography/, says: "Culture Name: Zambian."

UWashPrincipalCataloger (talk) 07:45, 9 March 2021 (UTC)

    • Well, all claims about ethnic groups should have such references. Ideally these meet the requirements of ethnic group (P172). The demographics article about the country seems to have a different view. If one uses two terms interchangeably, it's unclear why one would add claims with items for each as statements. --- Jura 08:00, 9 March 2021 (UTC)

Christine K Luscombe (Q45766736)Edit

Hi Adam, you have reverted my Edit on Christine K Luscombe (Q45766736). Here is the reference for "Country of Citizenship" [3] - so I would suggest to take both USA/JPN ?! In Germany you become a citizenship at birth for the corresponding country - is this other in the US ? Best regards, --Erfurth (talk) 09:46, 10 March 2021 (UTC)

@Erfurth: Japan has a rather strict ius sanguinis, so her birth in Kobe does not imply Japanese citizenship. As she wasn’t born in the US, her being an American citizen isn’t so sure either (but may very well be the case). Just leave it empty until proper references can be found. --Emu (talk) 10:12, 10 March 2021 (UTC)
@Erfurth, Emu: Agreeing with Emu, this is why I didn't include country of citizenship, because while it is likely she is an American citizen now, I didn't have any definitive information. I don't know if Japan requires someone to give up citizenship when they become citizens of another country, as some countries do. UWashPrincipalCataloger (talk) 17:40, 10 March 2021 (UTC)

ethnic group (Q41710)Edit

Hi, I have problem with your changes in Czechs (Q170217). After your changes there are 10 links to Czech Republic (Q213). But this object isn't related to the Czech Republic (See cs.wikipedia article or some links in encyclopedias). This is related to nation for long time in history. Same for Slovaks (Q171336). I don't understand sense of Czechoslovaks (Q100146275). There is Czechoslovakians (Q91075059), which was (1920-1948) real nation/nationality used in Czechoslovakia. After 1948 there were nationalities like Czechs (Q170217), Slovaks (Q171336) and others. Could you describe, what do you do? Skim (talk) 17:02, 10 March 2021 (UTC)

  • @Skim: Hi, I've made a new item Czechs (Q105969758) for the concept of residents/citizens of the Czech Republic, and I've moved many of the statements that were on Czechs (Q170217) to it. I will do the same thing with Slovaks. I think probably Czechoslovaks (Q100146275) and Czechoslovakians (Q91075059) can be merged, although the former is specifically for residents/citizens of Czechoslovakia as a whole, a label to describe them as a group. The latter seems to have more to do with a political concept of Czechoslovakism rather than a term for people who reside in a country. What do you think? UWashPrincipalCataloger (talk) 00:16, 16 March 2021 (UTC)
@UWashPrincipalCataloger: Ok, Czechs (Q105969758) and Czechs (Q170217) are somehow ok. I can't tell if Czechs (Q105969758) makes sense. I improved Czechoslovakians (Q91075059) for inception (P571) and dissolved, abolished or demolished date (P576) as official dates of this nation in Czechoslovakia (Q33946). I think, that's ok now. I will ping my community. Skim (talk) 06:29, 13 April 2021 (UTC)

Gymnocarpium ×brittonianum (Q17046489)Edit

I reverted your edits. --Succu (talk) 20:38, 10 April 2021 (UTC)

  • Why is that? Why did you remove instance of hybrid and the other common name I found in iNaturalist for it? UWashPrincipalCataloger (talk) 23:44, 10 April 2021 (UTC)

Amalia Rosenblüth (Rosenblueth)Edit

Hello, @Goesseln: wrote a new article (w:de:Amalia Rosenblüth) about Amalia Rosenblüth (Q101112434). She worked as a librarian at UWash and died in 1979 in Seattle. Do you have any idea how to find her exact death date online? Thanks a lot! --Emu (talk)

  Done I found her under her pseudonym! Sorry to bother you … --Emu (talk) 12:49, 12 April 2021 (UTC)
@Goesseln, Emu: I'm afraid you've confused two different universities. Her item says she worked at Washington University, which is a private university in Saint Louis, Missouri. It's often confused with the University of Washington, which is a state university in Seattle. UWashPrincipalCataloger (talk) 17:38, 12 April 2021 (UTC)
@Goesseln, Emu: After reading her Wikipedia article, it seems that it's her item that has the wrong information. I've changed the information so that it is correct. UWashPrincipalCataloger (talk) 17:40, 12 April 2021 (UTC)
Yes, indeed, sorry – American universities and their names are often confusing for me. Thanks for correcting the item! --Emu (talk) 20:11, 12 April 2021 (UTC)

May I borrow your time?Edit

One of my colleagues at English Wikisource put this local question Wikidata talk:WikiProject Periodicals#Properties for periodicals tiers: work/series/volume/issue/article and we would appreciate a professional PoV. We WSers are very good at transcribing old texts and getting better at presenting for the modern age. Cataloguing (and probably categorising) and the dark arts around the right meta data for the right place are less our skill set, so polite though firm commentary is always our wont. <shrug with rueful smile>  — billinghurst sDrewth 23:49, 14 April 2021 (UTC)

I'd be happy to try to help, but I am not a serials cataloger and haven't cataloged them for a very long time. There are some serials catalogers in the PCC Wikidata Pilot Project though (https://www.wikidata.org/wiki/Wikidata:WikiProject_PCC_Wikidata_Pilot), and you might get better information and guidance from one of them. If you'd like to compose an email to the pilot project participants, I could send it out for you on our discussion list and ask serials catalogers to contact you.

Hi! I noticed that you added statements related to reality TV shows that are singing competitions to Q60723717, but this is a more generic item for singing competitions on TV and off of it. Could you please create a separate item for the TV-related ones? Thanks :) -Yupik (talk) 07:51, 23 April 2021 (UTC)

Hi, Yupik, I have created television singing competition (Q106603795) and revised some items and added it as a genre to a number of additional items. Hope this helps! UWashPrincipalCataloger (talk) 19:04, 23 April 2021 (UTC)

Q9824248 vs Q99705827Edit

Could You please clear the relationship between Molecular Engineering & Sciences Building and Nano Engineering and Sciences Building before reverting my changes. Are these identical buildings (duplicate, with just different names?), different sections of one building or two different separate units? It is not optimal that there is now a link from Nano Engineering and Sciences Building to an archINFORM entry, which links back to Molecular Engineering & Sciences Building ! --Arch2all (talk) 08:20, 21 June 2021 (UTC)

Hello @Arch2all:. First, you reverted the items that I created, which I believe were correctly established. Your reversions indicated that you did not understand the nature of these two entities, so instead of reverting them, it would have been better to initiate this discussion first. These are two separately named buildings that were built in two phases. You can see them on a map and with description at https://www.washington.edu/maps/#!/mol and https://www.washington.edu/maps/#!/nan. The buildings are adjacent to each other. They were funded as one project with two phases of construction to build two separate buildings. Molecular Engineering & Sciences opened in 2012 and the second phase was completed with the opening of Nano Engineering and Sciences in 2017. Additional description can be seen at https://www.moles.washington.edu/facilities/building-2/ and https://www.engr.washington.edu/about/bldgs/nanoresearch. The archINFORM and PCAD entries describe the entire project which was called Molecular Engineering Buildings Phases I and II. Note the plural term "Buildings". Phase I resulted in Molecular Engineering & Sciences Building (Q98242488) while phase II resulted in Nano Engineering and Sciences Building (Q99705827). While this may be a bit unusual case, the archINFORM and PCAD identifiers identify what are ultimately two different buildings, and as such, the identifiers are appropriate on both Wikidata items. These are not identical buildings, and they are not different sections of one building. UWashPrincipalCataloger (talk) 17:50, 21 June 2021 (UTC)

GRY-Online vs Gry-OnlineEdit

Hmmm that is strange. I thought labels on wikidata should reflect rather names used by connected Wikipedia articles (see pl:Gry-Online and en:Gry-Online - only first letter is capitalized). Additionally, in Polish language capitalizing all letters of name, which is not an acronym is just typographically incorrect (I don't know if it's the same in English, though). Thanks. Sir Lothar (talk) 18:18, 9 August 2021 (UTC)

In most cataloging rules, which is what I am most familiar with, a basic principle is to record information like titles in the form that a resource represents itself. Here is the Statement of International Cataloguing Principles. These statements are the relevant ones:

2.3. Representation. Descriptions and controlled forms of names should be based on the way an entity describes itself.
2.4. Accuracy. The entity described should be faithfully portrayed.

I am fairly certain that labels on Wikidata do not have to match what is in Wikipedia. See https://www.wikidata.org/wiki/Help:Label: "There is no requirement that an item's label be the same as the page name on its corresponding Wikimedia site. In fact there are several cases, discussed below, in which it is actually desirable for the Wikidata label to be different from the Wikimedia page title."

--UWashPrincipalCataloger (talk) 18:28, 9 August 2021 (UTC)

I see. Thanks for clarifying this issue. I suppose I should change Polish label back to GRY-Online too? Sir Lothar (talk) 18:36, 9 August 2021 (UTC)
Yes, I would. :) UWashPrincipalCataloger (talk) 19:39, 9 August 2021 (UTC)

Open questionsEdit

Hi UWashPrincipalCataloger

Can you see that the missing samples issue per Wikidata:Property_proposal/setlist#Discussion are addressed? In the future, please ensure this is addressed before creating properties. Thanks. --- Jura 07:49, 14 August 2021 (UTC)

slender-billed prion?Edit

Do you read sometimes realated sources? --Succu (talk) 21:23, 16 September 2021 (UTC)

You can find numerous sources that capitalize the letters in various ways. The form of the label should not be based on one form of capitalization. Most of the sources for "Slender-billed Prion" are just the same publication in different versions. In English, common names of animals are not considered proper nouns (unless they have a geographic or person's name in them) and therefore are not capitalized in normal writing. I added additional capitalization forms and sources for them in taxon common name. The best label is uncapitalized. UWashPrincipalCataloger (talk) 22:12, 16 September 2021 (UTC)
This is your POV! There is no consensus for this here. --Succu (talk) 04:38, 17 September 2021 (UTC)

The standard guide for English writing is The Chicago Manual of Style, which says:

For the correct capitalization and spelling of common names of plants and animals, consult a dictionary or the authoritative guides to nomenclature, the ICN and the ICZN, mentioned in 8.119. In general, Chicago recommends capitalizing only proper nouns and adjectives, as in the following examples, which conform to Merriam-Webster's Collegiate Dictionary:

Cooper's hawk
rhesus monkey
Rocky Mountain sheep

The National Geographic Style Manual lists some common names (e.g., honeybee, tsessebe, Harris's hawk) and does not capitalize anything but proper nouns. See also: https://www.dailywritingtips.com/when-to-capitalize-animal-and-plant-names/, https://projects.ncsu.edu/cals/course/zo150/mozley/nomencla.html, https://mostlybirds.wordpress.com/2015/12/09/should-common-names-of-species-be-capitalized/, and https://grammar.yourdictionary.com/capitalization/capitalization-of-animal-names.html, among many others.

Also for virus names, see this, from the International Committee on Taxonomy of Viruses (ICTV): "The first letters of words in a virus name, including the first word, should only begin with a capital when these words are proper nouns (including host genus names but not virus genus names) or start a sentence. Single letters in virus names, including alphanumerical strain designations, may be capitalized. ... Examples:

   Isolates of dengue virus 2 were obtained ....
Detection of West Nile virus in human serum ....
Salmonella phage SE1 was isolated ....
Sida ciliaris golden mosaic virus (SCGMV) causes ....
Aphids transmit potato virus Y (PVY)

The Codes do not govern common names. At least two major sources (IUCN and IOC) do not follow your POV. --Succu (talk) 09:13, 17 September 2021 (UTC)

University of Alaska Anchorage (Q1285252)Edit

The problem with using 'parent organization' in this context is that the term (as defined on WD) has a very specific meaning. It's 'inverse item label' is "has subsidiary", with the inverse property subsidiary (P355). The Parent organization/subsidiary relationship is supposed to imply ownership of another organization that is 'completely separate', such as one company buying another. That kind of relationship doesn't generally apply to state university systems... the actual organization is typically (and seems to be the case in Alaska) a "Board of Regents" that is legally given 'governing authority' over the various universities, which do not themselves have a separate legal identity.... they are instead constituent parts of 'the system' governed over by the Regents.

The role played by the Board of Regents is far more significant with regards to the universities than simply 'owning' them... a Board of Regents, as a body corporate, does not in fact actually 'own' the universities (they are state property) but instead governs them according to the authority delegated by state law. State universities typically have their own police departments, that enforce not only state and local laws, but the regulations 'enacted' by the Board of Regents, with the force of law (as an example of how the situation is different).

The whole situation is altogether a different relationship than what is intended/implied by "parent organization" and "subsidiary". In a parent/subsidiary relationship, the control exerted by the 'parent' is not through direct governance, but instead through the shareholder's ability to appoint the management of the 'subsidiary' organization.... they remain, conceptually, 'separate things'. Jarnsax (talk) 15:01, 21 September 2021 (UTC)

Essentially, in a parent/subsidiary relationship, the parent is (talking legalistically here) a "member of the corporation" of the subsidiary, with rights defined by the articles of incorporation of the subsidiary, and controls the subsidiary through possessing the majority of member votes.

pulication date / inception on "Last Days" (Q44370964)Edit

May I ask why you removed "publication date" on Q44370964 and replaced it with "inception"? My understanding has always been that they refer to two different things with written works, namely when they were published and when they were written. Is it because part of the work had been published pror to 2009? But simply removing the property seems a suboptimal solution in that case.--Pfadintegral (talk) 06:15, 23 November 2021 (UTC)

Inception (date of creation) is used on items for works, whereas publication date is used on items for specific editions. Items are not supposed to combine both work and edition. The model that is supposed to be followed is at https://www.wikidata.org/wiki/Wikidata:WikiProject_Books. UWashPrincipalCataloger (talk) 18:20, 23 November 2021 (UTC)

I understand the need to separate works and editions. But if you restrict "publication date" to editions, how would you deal with cases like Q48229 where "inception" (when it was written) and "publication date" (when it was first published) have two different values? Do you think the date of first publication should simply not be stored on work items? --Pfadintegral (talk) 06:44, 25 November 2021 (UTC)

Yes, my understanding is that "publication date", even first publication date, is not supposed to be recorded on items for works, which also aren't supposed to have "publisher", "place of publication", "number of pages", "ISBN-13" and "ISBN-10" and other properties related to specific manifestations. Work itself is an abstract concept, so only "inception" (date of creation) should be given. Of course in many cases, the date of creation is inferred from the date of first publication. For Lost in America (Q48229), only the date the work was created should be there. There should be a separate item for the first edition published in 1927. Here's an example: work - Golden Boy (Q17105820), first publication - Golden Boy (2013 British edition) (Q109690729). UWashPrincipalCataloger (talk) 07:31, 25 November 2021 (UTC)


Could you please:

  • Edit the NACO/SACO data to be consistent with each other, eg:
    • the pref label should be "NACO"?
    • I think "part of" is enough, there should be no "subsidiary / parent org" because the subprograms are not orgs
  • Add BIBCO and CONSER
  • Add "participant" lists. I added such list to PCC, but actually that's the list for NACO (taken from the VIAF home page). If different subsets of libraries participate in the different subprograms, I'll need to fix that

Cheers! --Vladimir Alexiev (talk) 07:59, 8 December 2021 (UTC)

Yes, there are different participants in each of the programs. Some libraries participate in all four, but many are just NACO or SACO libraries. To be in BIBCO and CONSER, they have to be NACO participants. I can work on the BIBCO and CONSER items. UWashPrincipalCataloger (talk) 08:19, 8 December 2021 (UTC)

Q110271724 and Q6649Edit

Hi! I saw that you edited the page about "lesbianism" and added some to the "lesbian" page (which was created today), but since all these pages are talking about the same subject I don't see why separate them. That's why I propose that there is a fusion of the two so that the interwiki pages are not in different places just by name or that the interwiki pages are totally separated from Q6649 so that there is no confusion. --N4CH77 (talk) 23:36, 26 December 2021 (UTC)

studied by (P2579)Edit

Hi @UWashPrincipalCataloger:, why did you add student (Q48282) to the constraints of studied by (P2579) back in February ? Isn't practiced by (P3095) more appropriate for students ? For example, physics (Q413) practiced by (P3095) physicist (Q169470), why not the same for students ? I think that we are mixing very different entities if we use studied by (P2579) for both the discipline (activity) and the students (humans). Thank you for your help. CaLéValab (talk) 12:12, 27 December 2021 (UTC)

  • Hi, is it correct to say that physics is practiced by a physics student? It seems more accurate to say that physics is studied by a physics student. They can't really practice until they have mastered their studies. UWashPrincipalCataloger (talk) 19:13, 27 December 2021 (UTC)

New External Identifier property P10312Edit

Hi,UWashPrincipalCataloger. Thanks for creating this new identifier.

Since you did so, eleven hours have passed and still it appears that links created using the identifier (the three examples given as justification) while set up still are not clickable. Similarly a Quickstatements batch I have of 4200 updates to use the identifier fails on every one.

I just wondered if this time passing (until the identifier can be used) is normal or not - or whether I or someone else needs to do something to finish the process.

Thanks again.

Watty62 (talk) 19:12, 31 January 2022 (UTC)

  • Hi, yes it's normal, and can take as long as 24 hours or so before the links work. You can "purge" the record periodically to force the links to work, but I've tried that just now and it's still now linking. Hopefully later today it will work. UWashPrincipalCataloger (talk) 19:26, 31 January 2022 (UTC)
    Cool, thanks. That's reassuring. All the best. Ian Watty62 (talk) 09:15, 1 February 2022 (UTC)
The links are live now. UWashPrincipalCataloger (talk) 15:59, 1 February 2022 (UTC)

Authority control propertiesEdit

Hi, @UWashPrincipalCataloger. I have exchanged the position of LDT @ Library Name Authority ID (P10489) and NCL ID (P1048) in {{Authority control properties}}. They have two different UID. The IDs in P10489 are the same with CYT in Virtual International Authority File (Q54919). Kethyga (talk) 06:58, 14 March 2022 (UTC)


I've just tweeted DACS to see if they might have be able to give us a list giving their new IDs matched to their old IDs [4]. I'm guessing probably not, but no harm in asking.

In the meantime, can I suggest that when there has been a total change in IDs like this, it might be worth suggesting a new property, eg DACS ID (2022), to keep the new IDs completely separate from the old ones; and to redirect the old ones to point to something like [5] for Andy Warhol, by changing the URL formatter to https://web.archive.org/web/20210630075411/https://www.dacs.org.uk/licensing-works/artist-search/artist-details?ArtistId=$1.

(We had to do something similar for the Royal Academy identifiers a couple of years back).

That way the old IDs won't get muddled with the new IDs; and people will still be able to see what the information DACS used to give about them, at least as it was in 2021, for artists when we only have the old IDs.

Cheers, Jheald (talk) 18:45, 15 March 2022 (UTC)

Thanks for the suggestion and the tip. I think this might be the first time I've noticed this kind of change and didn't necessarily know how to deal with it in the best way. The tip about using the Internet archive address to replace the former URL is very cool. I'll revise the existing property with the redirect URL you suggest.

New proposal at https://www.wikidata.org/wiki/Wikidata:Property_proposal/Person#DACS_ID_(2022). UWashPrincipalCataloger (talk) 20:13, 15 March 2022 (UTC)
Thanks, I think that does make sense. The only exception would be if they did give us a list with the entire old ID -> new ID mapping, so that we could update all the values overnight, in one go (deprecating the old ones). So I am curious as to whether they will get back to me. But even then it might be cleaner just to have the new property.
That's a heroic set of translations of 'former', btw! Jheald (talk) 21:36, 15 March 2022 (UTC)
Thank you Google Translate! ;-) UWashPrincipalCataloger (talk) 02:07, 16 March 2022 (UTC)

Juniperus communis, etc.Edit

FYI: I've removed a whole lot of vernacular names that are only relevant to one or another particular subspecies, not to the species as a whole; please do not re-add them there, as it is misleading to suggest they apply to the whole species. Also please be careful about adding huge numbers of obscure and rarely-used vernacular names, as it just clutters up the VN listing at Commons and elsewhere; particularly not ones that are no more than typographical errors such as ommissions of hyphens due to sloppy editorial work at the references cited. Thanks! - MPF (talk) 16:06, 25 March 2022 (UTC)

Indiana State Historical Marker ProgramEdit

I made some adjustments to Indiana State Historical Marker Program ID (P9546) to model the related concept more clearly as you may have seen my changes to the property examples, adding constraints, and moving of IDs. I also created the second proposal for the numberic ID as it is critical to include to keep data linked long term if the URL changes as it is the most stable identification of the marker. See the new proposal - Indiana State Historical Marker Program numeric ID. I'm not sure the the Indiana State Historical Marker Program (Q106571962) "program" is the correct statement for what the marker IDs stated in or represent as much as the website or database of that program. Wolfgang8741 (talk) 17:21, 31 March 2022 (UTC)

I created Indiana Historical Markers (Q111442916) for the website, and replaced applicable 'stated in' value (P9073) with it instead of the Program. UWashPrincipalCataloger (talk) 17:50, 31 March 2022 (UTC)

Help with propertiesEdit

Hello! Would you help me fill in the properties All.Rugby club ID (P10590), traveloka restaurant ID (P10591), maPZS trails/locations ID (P10592) and Kinowiki ID (P10593)? MasterRus21thCentury (talk) 05:22, 9 April 2022 (UTC)

angiosperms (Q25314)Edit

You removed taxon name (P225) for angiosperms (Q25314) probably because that item is clade, but anyway, if you delete taxon name you have to add clade name or some other property name. Currently the item is taxonomically broken. --Termininja (talk) 14:58, 5 May 2022 (UTC)
