User:Mike Peel/sandbox[edit]

Hi Mike. On the french version of Wikipedia, I create fr:Module:Infobox/Télescope. We speak about that in fr:Projet:Astronomie/Porte des étoiles and fr:Discussion utilisateur:Simon Villeneuve.

We should work togeter to elaborate a common infobox. Jérémy-Günther-Heinz Jähnick (talk) 12:44, 25 June 2015 (UTC)

Hi @Jérémy-Günther-Heinz Jähnick: Sorry for not getting back to you about this sooner. It's great to see that the French Wikipedia is also starting to use Wikidata for infobox content! We seem to be taking quite different technical approaches with the same aim, though: you're creating a Lua module to form the infobox in its entirety (utilizing other lua modules for the template), while I'm trying to adapt the standard en:Template:Infobox call to use information provided by en:Module:Wikidata. You're probably using the better technical solution, but copying it over to enwp is beyond what I'm currently interested in: I'm more focused on how to start getting the content onto wikidata and auto-included on wikipedia than I am about the best code/method to do this (although @RexxS: might be more interested in this).
So, perhaps it would be best if we collaborated on how to structure telescope information here on wikidata, such that both our approaches can incorporate the information? Thanks. Mike Peel (talk) 20:19, 3 July 2015 (UTC)
@Jérémy-Günther-Heinz Jähnick: I've now updated en:Template:Infobox telescope/doc to reflect the current wikidata usage by that template. I'm not currently sure what to do about linking the other parameters for the template with wikidata - any suggestions? (also @RexxS: and @Filceolaire:.) Thanks. Mike Peel (talk) 21:28, 4 July 2015 (UTC)


Hi !

I removed the area (P2046) statement because of the imprecision of the property itself : 31000 square inches is obviously the area of the mirror of the telescope, not the area of the telescope itself Face-wink.svg

I agree the size of the mirror (both the diameter, area, and even concavity) is pertinent information, and I'd love to have that on Wikidata, but we need a property specifically for it - and trust me, I looked for one (to no avail) before outright removing the statement.

Alphos (talk) 21:26, 20 April 2017 (UTC)

@Alphos: Ah, I didn't realise there was that distinction. I'm using this parameter in en:Template:Infobox telescope for "collecting area", and thought it would be fine to use the "area" property for this. I'll propose a new property for this immediately. Please don't remove it from any other telescope articles until the info can be migrated over! Thanks. Mike Peel (talk) 21:28, 20 April 2017 (UTC)
@Alphos: Actually, before I propose a new property, what would you think to using something like applies to part (P518) -> "telescope surface" as a qualifier of the value? Where "telescope surface" is a new Wikidata entry (since one doesn't seem to exist at the moment). Would that work in place of a new property? Thanks. Mike Peel (talk) 21:38, 20 April 2017 (UTC)
I have to say it's only my opinion on the matter, and I'm just a regular user on Wikidata ; but you seem to get the distinction I'm making too, and I thank you for that !
Let's put it this way : an individual telescope worth mentionning here sits in a building, usually with a round top and a slit opening with a closable door : that building has a ground area and an office-space area. A telescope rarely stands on its end, but rather on a mechanized pedestal, which has a footprint ; and the amplitude of movement of the telescope body describes a portion of a sphere, which projects to a circle of a given area on the ground. And it of course has a mirror of a given size, which is likely the most important info about the entity. All these are areas : would you have them share a property ? From my point of view (tiny pun intended), it seems awkward that they would all be statements with the same property, no matter what qualifiers are given.
I would fully support a new property for mirror area, and would certainly also think about a property for diameter (since not all mirrors are plain disks, with some even having gaps, especially on newer, wider implements with adaptive optics) :-)
Alphos (talk) 22:30, 20 April 2017 (UTC)
If we can describe all of those areas, then that would be great, but that's a lot of areas! I'm not sure that they will be available for most telescopes, as astronomers don't tend to report those values (I say this as a professional astronomer - these areas aren't relevant for observations, but they will be present on architectural plans). For flexibility on Wikidata, it is useful to be able to add all of those values with qualifiers whenever they are available. However, dish areas is one of the important parameters of a telescope, and it is something that is often quoted (although sometimes as antenna effective area (Q571946) that depends on frequency!) so I've gone ahead and proposed Wikidata:Property proposal/Collecting area - please comment on that proposal there. :-)
Diameters are another issue... They can be extremely complex for telescopes! See Radio Astronomical Telescope Academy Nauk 600 (Q1590725) as an example, which has an annulus surface for the primary mirror, and either rectangular or conical reflectors for the secondary, and then sometimes even a tertiary mirror! So we need to be able to describe various different topologies, even if we flatten them to 2D. And that's before we get to segmented mirrors ... Thanks. Mike Peel (talk) 22:58, 20 April 2017 (UTC)
Eee-yup ! Let's not even mention segmented codependant optics like that of Q845304 or segmented optionally codependant optics like those of Q210997 (1, or 2, or 1 and 2 as an interferometer)…
Thank you for listening to my suggestion :-) Alphos (talk) 08:21, 21 April 2017 (UTC)

Donations and links[edit]

Hi, I noticed some of your clueful remarks on Wikidata recently at the English Wikipedia. Thanks for that. I just opened a discussion about phabricator:T175230 (I would have liked some smaller venue but didn't find one). By the way, I notice that Wikidata:Data donation uses the incorrect term "donation" instead of "release" or similar: I remember when you helped get the "donate files" removed from UploadWizard, so you might be interested in this. I'm especially appalled when I see some people talk about "data donation" when they really mean adding links which are probably worthless for Wikidata users but potentially very valuable for the target domain owner. --Nemo 13:03, 5 November 2017 (UTC)

Village and river[edit]

Hello, you merged village with river. — Ivan A. Krestinin (talk) 07:12, 6 January 2018 (UTC)

Ah, my bad, reverted. Sorry. Mike Peel (talk) 07:29, 6 January 2018 (UTC)

Sorting under Surname category in Wikidata infobox[edit]

I just noticed a problem with the surname category created by wikidata_infobox. The person needs to have a sort by their first name: [[:Category:Doe (surname)|John]]. Otherwise they all appear under the letter "D" for Doe. This is how categories for surnames should be sorted. --RAN (talk) 21:52, 5 March 2018 (UTC)

@Richard Arthur Norton (1958- ): I can't reproduce this - can you point me to a live example, please, or alternatively try using {{Wikidata Infobox/sandbox}} to see if that has fixed it? Thanks. Mike Peel (talk) 22:00, 5 March 2018 (UTC)
It looks like it was a temporary glitch, they are all sorting properly now. I would have noticed it much earlier if the error had been there all along. Thanks. --RAN (talk) 22:04, 5 March 2018 (UTC)

Mt. Wilson citation[edit]

Please provide a citation to a reliable source to support your edit to the location of Mount Wilson Observatory. Jc3s5h (talk) 12:08, 9 March 2018 (UTC)

@Jc3s5h: The coordinates? [1]. The previous ones were quite a way off (and were also unreferenced), see [2]. Thanks. Mike Peel (talk) 12:19, 9 March 2018 (UTC)

x Centauri[edit]

Note that en:x Centauri is not identical with sv:X Centauri to which you linked it on Wiki-data. X Centauri is a star with a variable designation. Deryni (talk) 06:01, 21 March 2018 (UTC)

@Deryni: Hmm, this is complex. As x Centauri (Q17041325) is instance of (P31)=Wikimedia disambiguation page (Q4167410), I'd say it's correct to have en:x Centauri and pt:X Centauri attached to that one, and that sv:X Centauri should be removed from it. We then have X1 Centauri (Q5097792) and X2 Centauri (Q5097795), which are the two pages linked to from the disambig pages. However, the new svwp article is not the same as either of those (the HD number is different), and it's not a disambig page, so I think it needs a new Wikidata item. So 4 items in total. Does that sound reasonable? Thanks. Mike Peel (talk) 16:16, 21 March 2018 (UTC)
It sounds reasonable to me, but x Centauri is not a variable designation, but X Centauri is. In EnWp X Centauri is a disambig page for the Bayer objects x1 and x2 but not a correct spelling. It should possibly be x Centauri. As for now there is also the disambig page no label (Q50628067) with one article, X Centauri. If you study the template for stars of Centaurus I think you see why capital R-Z, A-Q and RR-ZZ and AA-QQ followed by the constellation name are reserved for variable designations. Please study this and then make your decision, for I can hear that you are more experienced with Wikidata than me. All the best! Deryni (talk) 17:02, 21 March 2018 (UTC)
@Deryni: OK, how do x Centauri (Q17041325) (with no label (Q50628067) merged in) and X Centauri (Q50824512) look? Can you expand the latter with new properties? Thanks. Mike Peel (talk) 22:38, 21 March 2018 (UTC)
That looks real good. I'll take a lot at the properties. Deryni (talk) 04:53, 22 March 2018 (UTC)

Wikidata:Requests for comment/Privacy and Living People[edit]

You are receiving this message because you commented at the above RFC. There are additional proposals that have been made there that you are welcome to comment on. MediaWiki message delivery (talk) 03:50, 9 April 2018 (UTC) (for Rschen7754)


Hi Mike Peel, I noticed this edit by your bot. This is not helpful. There is a sad cycle happening in Wikidata:

  1. Somebody puts in a link to a Commons redirect (hey, Commons has an entry, we should link to it)
  2. Somebody sees there is a link to a Commons redirect and switches it for the Commons link redirected to, as if these two were interchangeable, instead of referring to two different concepts
  3. Somebody noticed that there is a link which is not only redundant but also a misfit: it needs to be removed.
  4. When it has been removed, somebody will put in a link to a redirect (hey, Commons has an entry, we should link to it)
  5. Etc

- Brya (talk) 04:27, 19 May 2018 (UTC)

@Brya: Hmm, this is an odd one. As far as I can see, the two topics are the same, they're just from different naming schemes - it's essentially a taxon redirect. So maybe this is one of the (few) cases where the link needs to remain as the redirect. The bot only makes that edit when there isn't another entry already using the commons sitelink, so I've reverted it and created no label (Q53769091), which should prevent the bot from repeating the change. Thanks. Mike Peel (talk) 12:11, 19 May 2018 (UTC)
Well, it is a recurring problem. Commons uses a Single Point of View perspective, while Wikidata needs to be compatible with a Neutral Point of View perspective. In this case the taxon concerned is likely to have the same circumscription in both items, but there are also cases where Commons adopts a viewpoint of a taxon that has been split or been merged as compared to items on Wikidata. - Brya (talk) 16:21, 19 May 2018 (UTC)

Adding Commons category links based on ID's[edit]

Hi Mike, I noticed this edit and wondered if you could also run that for other subsets. See Commons:Category:Cultural heritage monuments with known IDs for good options:

I'm currently running a bot with a different approach ([3]). The monuments database contains key + category information extracted from Wikipedia, but not so many Wikipedia's seem to be working on that. Multichill (talk) 15:30, 2 June 2018 (UTC)

@Multichill: Sure. It's now running through Cultural heritage database in Austria ObjektID (P2951), e.g. [4]. I've already run it through Historic Scotland ID (P709), Cadw Building ID (P1459), COAM structure ID (P2917), HPIP ID (P5094), and part-runs of NRHP reference number (P649) and National Heritage List for England number (P1216). If you can, please could your bot add the sitelink as well as the P373 (or instead of it, DeltaBot (talkcontribslogs) copies it over to P373 later) - although one of the other tasks of Pi bot (talkcontribslogs) should copy them over to the sitelinks at some point. Thanks. Mike Peel (talk) 16:04, 2 June 2018 (UTC)
Thanks, I'll just wait for Pi bot to come along. Multichill (talk) 20:23, 2 June 2018 (UTC)

Japanese family names[edit]

Hello, your bot is currently adding wrong properties family name (P734) for many Japanese people. Some examples:

--Santer (talk) 21:05, 25 June 2018 (UTC)

@Santer: Thanks for letting me know. I've stopped the bot until we figure this out. The bot currently does English label minus given name (P735) to get family name (P734) - which apparently doesn't work here since the English version of the family name is the same (except for the Kano/Kanou example, is that a typo in the English label?) Is there a way of doing the same in Japanese? Thanks. Mike Peel (talk) 21:16, 25 June 2018 (UTC)
Takashi Kano (Q744354) family name (加納) depending on its pronunciation could potentially be linked to 3 nearly similar names: Kanoo (Q26203566), Kanou (Q26203565) and Kano (non-existing yet). The English label would suggest that the third one is correct, but according to the name in kana (P1814) (カノウ タカシ) it's actually the second one. I think that for Japanese family names the safest way would be to check (1) if the native label (P1705) (or Japanese label) in the family name (P734) item is the same as the first characters of the person's name in native language (P1559) (ex. Kanou (Q26203565) "加納" – Takashi Kano (Q744354) "加納孝") and (2) if the name in kana (P1814) in the family name (P734) is the same as the first part before the space in the person's name in kana (P1814) (Kanou (Q26203565) "かのう" – Takashi Kano (Q744354) "カノウ タカシ" → "かのう たかし" (in this case there's an additional step to convert it from katakana to hiragana)). Santer (talk) 00:37, 26 June 2018 (UTC)

Commons category filter tweak[edit]

After this edit another bot does a correction. I noticed this on a whole bunch of pages. Probably some hidden character that you could also filter out yourself. Multichill (talk) 09:40, 7 July 2018 (UTC)

@Multichill: That's weird. It's not editing pi bot's change, which is to add the sitelink - it's editing the P373 value. Maybe @Ivan A. Krestinin: can you help figure out what's happening here? Thanks. Mike Peel (talk) 13:23, 7 July 2018 (UTC)

Wikimania 2018[edit]

Hi Mike,

I'm Charlie from the WMDE UX-Team. We briefly talked about Wikidata Infoboxes via Email. I saw here that you'll be attending Wikimania and I'd love to get a chance to talk to you in person about this topic in more depth. Let me know if you'd be interested and we could set up a time to meet during the event. I know the Wikimania days are pretty busy for everyone so I'm totally happy with a small slot sometime in between that matches your schedule :) cheers --Charlie Kritschmar (WMDE) (talk) 14:39, 10 July 2018 (UTC)

@Charlie Kritschmar (WMDE): Definitely! Maybe talking some time during the hackathon would be the easiest? Thanks. Mike Peel (talk) 15:02, 10 July 2018 (UTC)
Hackathon sounds great! I'll be there on both days. I'll try and find you during the first day :) thank you, and see you then! --Charlie Kritschmar (WMDE) (talk) 15:22, 10 July 2018 (UTC)
OK, see you there! If you can't find me, ping me here and I'll come looking for you. Thanks. Mike Peel (talk) 18:40, 10 July 2018 (UTC)

Moving commons category sitelink to category item[edit]

Could your bot please stop "Moving commons category sitelink to category item" for items like ? I find this "category item" a completely unnecessary complication, which does nothing but confuse and require extra clicks when navigating.--Hjart (talk) 12:51, 16 July 2018 (UTC)

@Hjart: Please see Wikidata:Requests for permissions/Bot/Pi bot 6 for the background. As far as I'm aware, the bot is following the consensus here. I'm happy to not run it for a bit if you want to raise this for wider discussion, though (say at Wikidata:Project chat). Thanks. Mike Peel (talk) 14:40, 16 July 2018 (UTC)
