Would you mind providing examples for your NARA property proposals at WD:Property proposal/Authority control? Thanks, --Jakob (talk) 21:18, 25 March 2014 (UTC)

I provided examples in the original proposal. Please see my comment in the discussion section. Dominic (talk) 19:45, 26 March 2014 (UTC)

NARA propertiesEdit

Hi Dominic, what is the status of these NARA properties?

A lot of them give broken links making them quite useless. I already pinged you on Wikidata:Identifier migration/1, but I guess you missed that. In the current state I'm probably going to propose to delete them, but maybe you can clarify things so it can be corrected. Multichill (talk) 09:45, 14 August 2016 (UTC)

Hey @Multichill. These are definitely an issue. NARA's catalog changed its domain and identifier structure last year. This was a good thing for us, because we moved to a single unified identifier system, called NAID (National Archives Identifier) for all catalog records and authorities, instead of many different ones. Any link to https://catalog.archives.gov/id/{id} should now work. This means all the existing identifiers could be merged into a single new National Archives Identifier property. I think the broken links for some of those are a bug in the URL redirecting. It seems to be only affecting authority identifiers(?). I will report it to our help desk and see what they say. Thanks! Dominic (talk) 17:38, 17 August 2016 (UTC)
Hey Dominic, I changed U.S. National Archives Identifier (P1225) to become the new property, but now I realize it's probably easier to just reuse P1222 (P1222). Looks like there is no need to change the id there. Multichill (talk) 20:03, 17 August 2016 (UTC)
Thanks, @Multichill:. I just removed all of the uses of P1223 (P1223), since there were only a dozen and they seemed all broken. Looks like the others are all not in use. So I suppose they can be deleted/redirected (or whatever is the proper action for Wikidata)? I've cleaned up P1226 so it is current. Are there properties for adding "former name" or "former URL"? I couldn't find anything useful. Dominic (talk) 21:06, 17 August 2016 (UTC)

NARA properties with issuesEdit

Hi Dominic -

I found another issue in the NARA database:

Thanks! - PKM (talk) 19:26, 25 October 2017 (UTC)

Thanks so much. I have sent both of these along for correction. Dominic (talk) 19:52, 31 October 2017 (UTC)

Muster RollsEdit

I've created a new item muster roll (Q65789047). I've added <has parts of the class> "muster roll" to your various NAID items (Muster Roll (NAID 3074205) (Q64531137) etc.). Should those be <instance of> "muster roll" now that it exists instead? - PKM (talk) 21:16, 22 July 2019 (UTC)

@PKM: Yes, I think it could make sense to add that as a value, but still keep "collection" as well? I would note that that example looks like it is a series that is literally a single muster roll, but there may be other cases (or most cases) where a series is composed of multiple muster rolls (or a muster roll and related objects). Thanks! Dominic (talk) 01:02, 23 July 2019 (UTC)

cco license for Narihira Viewing the Cherry Blossoms (Q60474748)Edit

Dominic ,

That statement is wrong as this is license for the image and not for the original which in the public Domain. Different photographs of the same image might come with different license, so that info should be stored with the file on SDC. --Jarekt (talk) 04:42, 10 January 2020 (UTC)

Ouch, that's 35.000 items to fix. Can you please undo these edits?
I can help you with adding the right data on Commons as structured data on Commons. Multichill (talk) 13:51, 11 January 2020 (UTC)
I will start removing License==CC0 statements from the items in your query, and if Multichill can add it to SDC than it will be all wrapped up. --Jarekt (talk) 03:56, 12 January 2020 (UTC)
  Done--Jarekt (talk) 17:12, 12 January 2020 (UTC)
@Jarekt:, @Multichill: Hi guys, sorry I didn't check my messages this weekend. I would have been happy to fix, but thanks for taking care of it! I was being a bit too literal with the data, you're right, but I'm also still in the middle of working through this dataset (especially the unmatched entities), for what it's worth, so I am still making improvements. Dominic (talk) 02:14, 13 January 2020 (UTC)

Cleveland no tiffEdit

Hi Dominic, I still have User:Multichill/Zandbak (https://www.wikidata.org/w/index.php?title=User:Multichill/Zandbak&oldid=956888345 permalink]) sitting around with items about paintings that don't use a tiff image. Want to look into this? Multichill (talk) 13:33, 11 January 2020 (UTC)


Why on earth are you making new items like this: https://www.wikidata.org/wiki/Q80000906

...that is just one copy of the David Roberts litographs, out of hundreds? thousands? There are many, many on commons, just look at the el-Deir lito (see https://commons.wikimedia.org/wiki/Category:Jordan_by_David_Roberts)....are we going to have an item on wikidata for each of the 8 copies on commons? Huldra (talk) 23:04, 16 January 2020 (UTC)

I am importing all of the artworks described by the Cleveland Museum of Art. This is a notable work described in a museum's collections database, and it is clearly in scope according to Wikidata:Notability. Can you explain further what problem you think this causes? I can't speak for other versions on Commons, as I did not do anything relating to them, but considering they might all be distinct physical manifestations with their own locations, provenance, physical condition, etc., and cataloged by reputable institutions, I wouldn't immediately reject the idea that they might merit separate items. Dominic (talk) 01:47, 17 January 2020 (UTC)
The lithograph above (one of many!) is Plate 091 in vol 3 of en:The Holy Land, Syria, Idumea, Arabia, Egypt, and Nubia. Link here. If you look at the commons category there are at least 3 similar pieces on commons (there might be more, I have just not found them yet. In fact, there normally are 3 to 7 copies of each lithograph on commons. What you are doing is basically similar to creating a wikidata entrance of each and every copy of a Dickens 19century book: do you think this is sensible?? (even if every copy of his books have "distinct physical manifestations with their own locations, provenance, physical condition") --Huldra (talk) 21:09, 17 January 2020 (UTC)


Why are you adding accession numbers to labels? Help:Label indicates that the "most common name that the item would be known by" ought to be used, and that will typically be simply the painting's title. Nikkimaria (talk) 00:11, 11 February 2020 (UTC)

Wikidata's software does not allow multiple items to share the same label and description. Using the title alone is often insufficient for a bulk import such as in this case when an entire museum's catalog has been added to Wikidata, since there might be works with the same title that would have the same description. From a data perspective, this should not cause any real issues, since if someone wants an item's official title, they should consult that property, and not the label. Dominic (talk) 00:13, 12 February 2020 (UTC)
It would seem that the appropriate solution would be to elaborate the description, perhaps by adding the accession number there rather than in the label. Nikkimaria (talk) 04:10, 12 February 2020 (UTC)
@Nikkimaria: Sorry for being offline over the weekend. I am working on this now. My main concern was overwriting descriptions, that may have been added or improved by humans, to enforce the accession number. That is not an issue for labels, which should not change, so that's why I designed it this way. The import script I am using is kind of dumb in this regard, and just detects any differences and then updates the values, but will not distinguish between changes made by editors versus changes due to the data being out of sync. However, if this is the preference, I can go ahead with what you are suggesting, and assume that the risk in updating existing descriptions is small. As a demo, I just updated the first 50 artworks like so. Let me know what you think. Dominic (talk) 19:42, 17 February 2020 (UTC)
Definitely think that approach is better. If overwriting is a concern, is it possible to simply append the accession number without changing the existing description? Nikkimaria (talk) 20:44, 17 February 2020 (UTC)

Teapot (Q79488050)Edit

Hi, Dominic (talkcontribslogs), wondering if the teapot you are refering to looks like this. :-) Lotje (talk) 13:01, 3 April 2020 (UTC)

Your revert on "copyright license" (P275)Edit

Hi Dominic,

your revert https://www.wikidata.org/w/index.php?title=Property:P275&oldid=prev&diff=1185781289 seems to have re-introduced an inconsistency that leads to errors. See discusson of copyright license (P275). Trilemma2 (talk) 17:53, 23 May 2020 (UTC)

I agree with Multichill's change. The inconsistency was a problem, but the way to solve it was not to just remove the valid constraint. Instead, if anything, the one that permitted "public domain" as a license should have been removed, which is what he just did. Your change, rather than solving a problem, was allowing people to put in a value that isn't allowed under the property's scope. Dominic (talk) 00:34, 24 May 2020 (UTC)

Advice for new WD editors bulk uploading museum collection data?Edit

Hi Dominic--

  Hope you won't mind me reaching out--I'm a relatively new WD editor working on a sizable batch upload of archaeological objects from the Yale University Art Gallery collection. I've noticed the Cleveland collection has a bunch of objects of similar type to those we're grappling with, and since you're handling that collection and clearly experienced with WD, I wondered if you might be open to advising my colleague and I on some of the gnarlier issues we're running into with getting our objects aligned for a batch upload. 
  We're particularly challenged with some issues around designating chronology of objects (specific date ranges for archaeological objects--of the sort where there's a sizable range when the object could have been produced: ie. 165-256 CE; also historical periods like "Roman", "Parthian", etc. where the colonial history of a single site means that the parameters for the relevance of such historical designations would be highly particular to that single site). I notice you haven't dealt with chronological statements on the archaeological objects from Cleveland (at least the ones I've been viewing)--I assume this is for good reason and that you might have thoughts on the complexity of dealing with chronology in WD, or might be able to point us to another experienced WD editor who might be helpful.

Thanks in advance-- Ahc84 (talk) 14:49, 14 September 2020 (UTC)

Hi Ahc84! I'm not working for CMA anymore, but I'm still doing Wikimedia work for DPLA, and happy to advise. If you want to reach out to my email, at dominic dp.la, I'd be happy to meet with you all and discuss Wikidata strategy in detail. My calendar is open on Thursday right now, if that works for you. Dominic (talk) 01:00, 15 September 2020 (UTC)
