There is always one IUAPC and most of the time you can put more than one. And as IUAPC is going to publish some rules to select the preferred name when several possibilities exist (see here, we can define one name for that property. Snipre (talk) 12:49, 26 June 2013 (UTC)[reply]
I have noticed French language using alternative characters with accents for the names, which does not quite match use in English. So is the non accented use correct? Graeme Bartlett (talk) 08:15, 29 June 2013 (UTC)[reply]
In French non accented names are not correct. That's why a multilingual property is proposed: each language will have its own name, so the value of this property will be a list of chemical names associated with a language. Snipre (talk) 08:32, 29 June 2013 (UTC)[reply]
Support, though the domain should probably be refined to "chemical compounds". Otherwise perhaps I'll finally get to see the IUPAC name for titin! It would also help to have an example, if only for documentation. Proposing a canonical source for IUPAC name claims would be helpful, too. Emw (talk) 12:14, 29 June 2013 (UTC)[reply]
Support – IUPAC name property should be available. It's rather a unique identifier in a sense that a IUPAC name defines single compound. There can be more different IUPAC names for single compound (but it is the case for SMILES strings, maybe even "canonical" as well). For that type of uniqueness, the PIN (Preferred IUPAC Name, introduced in 2013) can be used (which however is still somewhat open problem, e.g. for natural compounds). —Mykhal (talk) 18:44, 29 March 2020 (UTC)[reply]
Description/review (en)
Agreed to be created; waiting for multilingual text datatype
Exploratorium (Q206518) -> A great kid friendly option, with lots of interactive exhibits teaching about science, with intriguing displays about the mind, natural systems, sound, sight, and much much more.
Support but why the name "personal"? Wikivoyage POI descriptions feel indeed more personal than Wikipedia sentences, but they are not the result of a single individual, they are most often the result of a wiki collaboration. Nicolas1981 (talk) 08:04, 28 November 2013 (UTC)[reply]
Support. Property should be number with unit type hours. Needs a 'day' qualifier property to say which day the time given applies to (mon, weekdays, bank holidays, second tuesday in the month). Filceolaire (talk) 23:53, 18 August 2013 (UTC)[reply]
epoch refers to 6 orbital parameters: how to join them?
for spaceflights and artificial satellites the epoch is expressed in usual calendar unity; for extrasolar planet in Julian day or some its variants. How to solve it?
Support It might be useful to have a specific property because it can be further developed to have customisations and different representations (J2000, TT, etc.). As for bundling orbit parameters, one possible solution is to have an item to represent the orbit and link it with a property "orbit parameters". --Micru (talk) 20:37, 12 November 2013 (UTC)[reply]
I am not an astronomer and having read the en:Epoch (astronomy) article I am still confused.
On the one hand epoch refers in some way to unusual ways for expressing calendar dates - for these we could use the current wikidata time variable type and ask the devs to offer alternative ways of displaying this at some future date
on the other hand it seems to refer to unusual units of time (Julian years and Julian days) - for these we can use seconds until the devs get round to creating alternative units of time
on the third hand it refers to IAU standards - we can create items for these
I have amended the example as I understand it should be used. Please check I got it right.
Can this property be extended so it can be used on solar eclipses as well? Creating a property that can only be used on lunar eclipses seems a bit narrow. Filceolaire (talk) 00:10, 29 April 2015 (UTC)[reply]
P1-4 and U1-4 apply to solar and lunar eclipses, but differently. A solar eclipse is a en:Transit (astronomy) so the timing is based on the viewing location INSIDE a shadow, while a lunar eclipse has viewers looking at an object INSIDE a shadow, so everyone sees the same appearance at the same universal time. So knowing the P1-4,U1-4 times for a solar eclipse are less useful for any given observer. Tomruen (talk) 01:08, 30 April 2015 (UTC)[reply]
If U4 for a solar eclipse is different from U4 for a lunar eclipse then we should have separate items for these with the "applies to part" qualifier linking to the appropriate item in each case. This means this property could be used for solar eclipses if we just change the label. I would Support this property if you made this change to the property label and description. Filceolaire (talk) 03:04, 30 April 2015 (UTC)[reply]
Could you explain what you mean by "This means this property could be used for solar eclipses if we just change the label." Does that mean that properties can have more than one label? Or do you mean that you could have two statements for "subject item of this property"? Or do you mean something else? MSGJ (talk) 12:24, 30 April 2015 (UTC)[reply]
Rename the property as "Contact time for eclipses". Change the description to "Contact time for lunar and solar eclipses (U1, U2 etc. lunar and U1, U2 etc. solar)". Filceolaire (talk) 16:41, 30 April 2015 (UTC)[reply]
I would like to make a tool in toolforge that will allow a user to input an IP address and get the organization (Q43229) associated for that IP address. Unfortunately, you cannot query a range unless you have the start and end of that range. Based on the discussion in the previous proposal it seems best that a new datatype would be created for this property, one that extends from Quantity. Then organizations will be able to be queried by the IP address. U+1F360 (talk) 20:59, 1 November 2019 (UTC)[reply]
Discussion
After the property is created, the old properties should be deprecated. Once all of the data has been migrated, the old properties can be removed. U+1F360 (talk) 21:03, 1 November 2019 (UTC)[reply]
Comment if you want to make a tool anyway, then I suggest you do the indexing there. Looking at the Phabricator ticket, there is not a huge appetite for deploying a dedicated datatype for this. − Pintoch (talk) 18:58, 3 November 2019 (UTC)[reply]
In Wikimedia Commons there are thousands of images depicting lexemes (a few of them: c:Category:Images by text, not categorised by language yet). Creating a property to indicate the lexemes depicted in a file would be great (IMHO) with regard to structuring linguistic data in media files. This was posted here. Apparently this was also proposed here a few months ago. strakhov (talk) 16:06, 16 July 2022 (UTC)[reply]
Discussion
Comment To make this really useful, wouldn't it be better if it was "depicts lexeme form"? That way, we would capture more specifically what is on the image. Ainali (talk) 17:31, 16 July 2022 (UTC)[reply]
Comment I don't know. That way it would be captured more specifically what is on the image, for sure, but in the other hand it may make more difficult/complex introducing data. Are there already in Wikidata other properties with the lexeme datatype using forms? strakhov (talk) 10:03, 17 July 2022 (UTC)[reply]
@AntisocialRyan: In fact this property is not intended to be used as a qualifier, but as a main statement. But not (at least not mostly) here, but in Wikimedia Commons, with media files. strakhov (talk) 16:10, 18 July 2022 (UTC)[reply]
I would like the description to be more explicit about what depicts means. What's valid and what's not valid as an image for depicts? ChristianKl ❪✉❫ 13:55, 18 July 2022 (UTC)[reply]
@ChristianKl: with regard to the description, mirroring P180's English description, "word visually depicted in an image, see also P180 for entities depicted" may work (?). But please feel free to propose a better one.
With regard to what's valid and what not... I guess it's valid when the lexeme form is depicted in the file. Since depicts (P180) has no indication for what's not valid and what is valid, I do not know why this one would need such prescription. Use of P180 is at the discretion of the user and common sense. Anyway, if you believe there are situations when a form is depicted in a file but using this property would not be valid, please indicate them here. strakhov (talk) 15:59, 18 July 2022 (UTC)[reply]
Comment We should principally be using inscription (P1684) for text on depicted items. Not sure how the present proposal relates to that. And wary that this property might lead to a *lot* of statements per image. Jheald (talk) 15:35, 18 July 2022 (UTC)[reply]
@Jheald: inscription (P1684) is for entities, concepts, etc, not text: it's language independent, it does not capture different languages being used nor synonyms in the same language (but it captures senses). I guess the problem with someone adding a lot of "depicts lexeme form" statements is not different to someone adding too many P180/P1684P6568 statements (that properties could also be abused). Anyway, if someone believes a big "please, do not try to transcribe full book/newspaper pages such as this one while using this property, try to use common sense" is needed... Cheers. strakhov (talk) 15:59, 18 July 2022 (UTC)[reply]
You are absolutely right about this proposal not relating to that property. My bad, I did not consider that one. Well, I guess inscription (P1684) is good for transcribing full sentences (they can be added in the file description, file caption, as free text,... too). But it's pretty bad when it comes to crosslinking Wikidata Lexicographical data and Wikimedia Commons. I am interested in the latest. strakhov (talk) 15:20, 19 July 2022 (UTC)[reply]
Support in thinking about this, this would open up some interesting possibilities. If we want to document information about what a word looks like written by hand, which can often differ from the digital representation, this would be useful for linking photos showing this to lexeme forms. I uploaded an example of سلسہ just now which I would add this property to if available.
Question What about homonyms? Those might be forms of distinct lexemes or even of the same lexeme, e.g., in the case of inflection. Are editors adding statements with this proposed property to images supposed to work out which of potentially several possible lexemes (and therefore senses) might apply? Which grammatical features apply? What if the inscription is intentionally ambiguous? Or if the image is taken too far out of context? ―BlaueBlüte (talk) 04:38, 1 February 2023 (UTC)[reply]
