Renaming a item edit

Hi, thanks for your work on the National Register of Historic Places! It's fun that at least one other user is interested in the subject in North America. Just a note, when you rename the label of a item, like NRHP district (Q20856087), just put the old name in the aliases, so the user who use the old name could find it. --Fralambert (talk) 01:16, 11 January 2018 (UTC)Reply[reply]

Great point! Will do in the future. Btw, I am in the process of proposing some new National Register-related properties for use as qualifiers to heritage designation (P1435):National Register of Historic Places listed place (Q19558910). Take a look at Wikidata:Property proposal/Place. As a relative newbie on Wikidata, I'm being bold but would appreciate a second opinion from someone familiar with the NRHP. — Ipoellet (talk) 01:20, 11 January 2018 (UTC)Reply[reply]
Yes, I seem the proposal and I suported it, it seem a good idea. I work primally on the heritage properties in Canada. I finished all the provincial and municipal heritage properties (or monuments) in Alberta and Quebec and I work slowly in Prince Edward Island (PEI Register of Historic Places ID (P763). I am actually working to complete the Registered Heritage Place (Q14897292). But if you think to add some contraints on NRHP reference number (P649) or even some complex constraints in Wikidata:Database reports/Complex constraint violations/P649, let me know, I will help you. --Fralambert (talk) 02:03, 11 January 2018 (UTC)Reply[reply]

Redacted not part of sourcing circumstances (P1480) edit

P1480 is about the truthfulness of the value, whereas "redacted" is about a statement in the source in a work, not about the truthfulness of the value. As such you shouldn't be using P1480 to indicate that a reference statement is redacted. P1480 is a qualifier, whereas what you seem to be wishing to do use as part of the reference. I have undone your addition of redacted as a suitable qualifier.  — billinghurst sDrewth 12:56, 6 February 2018 (UTC)Reply[reply]

unknown value in P625 edit

Intead of create a long list of exceptions for the archeological sites, maybe use unknown value? I made thsi adition to Haputo Beach Site (Q20658354) what do you think? --Fralambert (talk) 01:49, 11 February 2018 (UTC)Reply[reply]

@Fralambert: If using unknown value avoids triggering a constraint violation, then I'm happy to use it because it's easier. Thanks for the suggestion. A longer-term philosophical issue would be that these coordinate locations are only unknown publicly: there is a difference between "unknown" and "confidential". Is it fundamentally appropriate to use unknown value if the value is in fact humanly known, just held confidentially? — Ipoellet (talk) 06:45, 19 February 2018 (UTC)Reply[reply]
Another issue I noticed in Cronin Point Site (Q23926608), where you removed address restricted (Q47460806) from location (P276) to a qualifier of coordinate location (P625). The problem is that when people in other projects query NRHP data from Wikidata, we're giving multiple different properties to look at for "address restricted" info. Personally, I'd rater leave address restricted (Q47460806) uniformly under location (P276) across all items for consistency and downstream user frendliness. — Ipoellet (talk) 07:00, 19 February 2018 (UTC)Reply[reply]

P131 edit

Re [1], "you only need to add one" isn't the same as "you must only have one", there's no singular value constraint on the property. In this case, the values are shown in the infobox at en:Arecibo Observatory, where the location either reads "Arecibo, US" or "Arecibo, Puerto Rico, US" depending on this edit. Originally, Puerto Rico was set to the country, but @Fralambert: disagreed (see the edit history of the page). I think Puerto Rico needs to be mentioned *somewhere* in the properties, as it's not trivial (or server-cpu-friendly) to have to follow the links through multiple Wikidata items to find it. Thanks. Mike Peel (talk) 11:26, 22 March 2018 (UTC)Reply[reply]

@Mike Peel: I was wondering if you might parse the instruction that way. I'm kind of torn, because on one hand I get and am willing to comply with the current concept of located in the administrative territorial entity (P131) that we should let the lowest level of the hierarchy imply all higher levels. OTOH I feel that approach leads to ambiguity where subdivisions aren't perfect (e.g. a point in Salem (Q43919) might be in either Marion County (Q484408) or Polk County (Q495393); merely specifying Salem doesn't determine which county the point is in). Using P131 to capture all levels of hierarchy rather than just one could solve that. Then there's your PR concern, which is also a real issue. So I'm just going to back off and let you proceed to have both Arecibo and PR statements. Please forgive me for stirring up a mess in the first place. — Ipoellet (talk) 15:53, 22 March 2018 (UTC)Reply[reply]
@Mike Peel: For Puerto Rico, it could be put as a country, since it's a associated state and have is own ISO 3166-1 code (PR), but we have probably to change how we see colonial or oversea territories in Wikidata, or at least the way we look at it in the United States. Is United States of America (Q30) reprensent only the 50 states + DC or it aslo include the other territories? I also see that Puerto Rico (Q1183)} have neither country (P17) and located in the administrative territorial entity (P131), who is strange. Ipoellet For the municipalities who are in more that one county, maybe you sould use territory overlaps (P3179) for the county and use the state for the city in located in the administrative territorial entity (P131)? --Fralambert (talk) 00:20, 23 March 2018 (UTC)Reply[reply]

Special:Diff/690984018 edit

Hi! You say that say my edit was unexplained. In fact I referred to a discussion which covers the problem. In short: there are settlements (cities among them) that are not administrative units (e.g. settlements in Estonia) or not even designated territorial units with specified borders. So particular cities that are not administrative entities are currently wrongly classified as ones. The solution is to use Q56061 for instances/subclasses (e.g. Q15063611) that actually are administrative entities. 06:46, 6 June 2018 (UTC)Reply[reply]

@ I apologize that I failed to notice that you did indeed cite a prior discussion. I also looked over that talk page and failed to identify that discussion as relevant to this issue - another oops. I can't say I necessarily agree with the reasoning in that discussion, but a discussion was had. The solution you suggest is one that has previously occurred to me, although for different reasons. (Specifically, that "city" as constitutionally defined in my state of Oregon is very different from e.g. the notion of "city" in the UK. Heck, Greenhorn (Q721338) has a census population of 0.) So anyhow, I see your point and I'll leave the matter alone. Thanks. — Ipoellet (talk) 19:41, 6 June 2018 (UTC)Reply[reply]

Blackstone Canal edit

I'm am not sura about Blackstone Canal (Q4923399). The entry of 1995 (95001004) should a another item or not? --Fralambert (talk) 23:07, 3 October 2018 (UTC)Reply[reply]

@Fralambert: The available National Register documentation appears to treat the Rhode Island segment (71000030 and 91001536) and the Massachusetts segment (73000328 and 95001004) as two separate NRHP listings. The structure of the list articles at enwiki also follows this pattern. In addition, it also looks to me like 95001004 is just a continuation/expansion of the same listing started in 73000328, rather than a separate listing. I suggest keeping Blackstone Canal (Q4923399) as an item relating to the canal as a whole but without NRHP information. That item can then be linked through has part(s) (P527)/part of (P361) to two new items relating to the respective segments in each state. These two new items are where the heritage designation (P1435) and NRHP reference number (P649) statements would be found. If you like, you can just leave it up to me to carry out my suggestion - your choice. — Ipoellet (talk) 19:51, 8 October 2018 (UTC)Reply[reply]
  Done with Blackstone Canal, Massachusetts Segment (Q57084142) and Blackstone Canal, Rhode Island Segment (Q49242758) (I merged the part in Rhode Island with a duplicate if cebwiki.) You can check the two item if they seem fine. --Fralambert (talk) 20:35, 8 October 2018 (UTC)Reply[reply]
@Fralambert: Thank you for working on that thorny problem! I have made some edits to the two new items that made sense to me - I hope they work for you as well. I also made some edits on enwiki and Commons to reflect what we have done here. — Ipoellet (talk) 21:09, 10 October 2018 (UTC)Reply[reply]
No problem, it was not really different of when I slipt Rideau Canal (Q18087815) and Rideau Canal (Q651323), the World heritage site including the Kingston Fortifications (Q18085382). --Fralambert (talk) 22:33, 10 October 2018 (UTC)Reply[reply]

NRHP sites edit

I've been working through the set of California Office of Historic Preservation Historical Resources (Q57955877) on Mix-and-Match, which includes all of the NRHP sites in California, and looking for guidance/best practices on how to populate and reference NHRP sites properly. I stumbled across your work on NRHP Nomination forms - thank you so much for these! Are you doing them in some automated fashion, or by hand? If you have a process, I don't want to step on it.

I have run into sites like Vacaville Town Hall (Q38251612) (just found today), and some which have no EN WP articles at all, so building these out leaves a lot of work to be done. - PKM (talk) 21:12, 2 November 2018 (UTC)Reply[reply]

  ?item wdt:P131 ?town .
  OPTIONAL { ?item wdt:P625 ?coords . }
  OPTIONAL { ?item wdt:P18 ?image . }
  SERVICE wikibase:label { bd:serviceParam wikibase:language "en" . }
GROUP BY ?item ?itemLabel ?townLabel ?coords ?image

Pennsylvania State Capitol edit

Hi, I am not sure how to resolve the link between Pennsylvania State Capitol (Q2915393) and Pennsylvania State Capitol Complex (Q29824585), since the National Register of Historic Places listed place (Q19558910) of the first moved to the second in 2013? Could you help me. --Fralambert (talk) 02:12, 15 January 2020 (UTC)Reply[reply]

@Fralambert: I've set the two items up in a way that makes sense to me. I based it on the prior example of Berrien Springs Courthouse (Q38250825) and Old Berrien County Courthouse Complex (Q33084567). I hope that helps. — Ipoellet (talk) 04:35, 15 January 2020 (UTC)Reply[reply]

Incorrect use of instance of (P31) edit

Hello –

This edit to "St. Ignace Mission" (Q3316762) was in error. The properties instance of (P31) and subclass of (P279) define key ontological relationships. Because subclass of (P279) is transitive, such errors lead to numerous false inferences, such as St. Ignace Mission (Q3316762)instance of (P31)behavior (Q9332). Before you use these properties, please look at the value item in your statement to be sure it's the one you intend. You can also review the usage instructions on these two properties, and Help:Basic membership properties. (In particular, note that all instances of a class must be of the same type.) There is often another property better suited to expressing the relationship you had in mind; you can search for one here. In this case, has use (P366) works better. Thanks!
