Motivation

At this moment Project:Books advices to use of published in (P1433), but distinct property is better. It is much simple to check single property (in LUA) and find out book series instead of generic property along with complex condition checks like "if it's a book, we will call it series, otherwise we will call it book/journal/something else". Vlsergey (talk) 14:57, 13 August 2015 (UTC)

Discussion

@Izno: Okay, let me provide more detailed example with explanation why P179 is different:

  • Creative work Day Watch (Q2714888) is part of Q20826824. It is what P179 is about and shall be used, i.e. P179 is creative work (FRBR work) property. This creative work was published as part of several books:
    • ISBN 5-17-008349-1 -- 2006 year -- as part of book series called "Звездный лабиринт"
    • ISBN 978-5-17-084937-6 -- 2014 year -- as part of book series called "Проект Сергея Лукьяненко «Дозоры»"
    • ISBN 5-17-025883-6; -- 2004 year -- out of any book series
  • Thus, i need a property used strictly for FRBR item (not FRBR work). It is possible that single Wikidata item will have both P179 and new property specified, but with different values. -- Vlsergey (talk) 14:57, 17 August 2015 (UTC)
Vlsergey, FRBR 'item' is wikidata 'edition'. Yes? Each edition has a publisher (P123) which could sort of do this however many publishers have separate brands which they use for different niches. Penguin Books (Q1336200) has Puffin Books (Q4907694) for kids and Pelican Books (Q17092380) for non-fiction; Gollantz Science fiction books all had yellow covers; Harlequin has multiple 'imprints' for different types of romance novels. I know that many publishers of translations have separate brands for detective, science fiction etc. Is that what this property is for? Could we just use publisher (P123) and have separate items for each brand/imprint with owned by (P127) to indicate which conglomerate owns each of these? I see that Template:Книга (Q909529) has separate items for 'series' and 'publisher' but it isn't clear what the difference is. If this really is a different property then I want to make sure the English description makes clear what it is for and what it is not for and I don't think we are there yet.Joe Filceolaire (talk) 13:14, 24 August 2015 (UTC)
@Filceolaire: it is close by description, but different in details. In Russia publishers do not use different brands, but merge books using same cover style. The most famous, IMHO, are Library of adventure and science fiction (Q4086379) and Q4180211. This "book series brand" can be used by different publishers, and according to our bibliographical description standard (ГОСТ 7.1—2003) "seria" ("Область серии") is a distinguished field from "publisher" ("Область выходных данных"). -- Vlsergey (talk) 13:42, 24 August 2015 (UTC)
Thank you Vlsergey. Can you try and add statements to Library of adventure and science fiction (Q4086379) to give us an idea as to what a typical 'book series' is? From the google translation of the russian wikipedia article (ru:Библиотека приключений и научной фантастики) it looks like it is a publisher. The article specifically says the brand is copyright and the various versions of this in the post soviet era from other publishers all seem to use slight variations of the name to distinguish themselves so they don't infringe on the brand - in looks like the "book series brand" cannot used by other publishers. Joe Filceolaire (talk) 14:36, 24 August 2015 (UTC)
@Filceolaire: found another good example, already filled with some properties: Lecture Notes in Computer Science. It is owned by single publisher as well (it may be usually the case), has a lot of books inside (~2k) and common topic. And it is obviously about topic and representation, not about content (i.e. no common characters, no common "world"). Regarding brands. "Lectures" are published under brand "Springer Berlin Heidelberg", but some of the books under "Springer Science+Business Media". I.e. it is not "publisher" field value to use. The thing i need is "series" field of w:BibTeX book format (and it is different from "publisher" field). -- VlSergey (трёп) 07:55, 17 December 2015 (UTC)
  •   Oppose Use part of the series (P179) or collection (P195). Swpb (talk) 14:00, 2 February 2016 (UTC)

  • @Vlsergey: I also see problems in the label of this property, I know what you mean, but it can be quite confusing if you are not familiar with the structure. I suggest cancelling this proposal and resubmitting it as "printed in" which I think it would be more clear.--Micru (talk) 07:31, 2 March 2016 (UTC)

All software and hardware released for PlayStation consoles (and even the consoles themselves) is assigned a unique reference by Sony Computer Entertainment Inc. This helps correctly identify a product, especially where two or more products share the same name. For example, Ridge Racer (PS1, PAL) is SCES-00001 and Ridge Racer (PSP, PAL) is UCES-00002.

Twitter hashtag

   Done: hashtag (P2572) (Talk and documentation)
Descriptionthe most used Twitter hashtag associated with this entity
RepresentsTwitter (Q918)
Data typeString
Allowed values[A-Za-z0-9_]+
ExampleFrench National Assembly (Q193582) → DirectAN
Formatter URLhttps://twitter.com/search?q=%23$1
Motivation

For instance, in France, there is this de facto rule among citizens using Twitter to use the #DirectAN hashtag to comment discussions at the French National Assembly (Q193582) but foreign observers often miss this piece of information and thus miss very valuable inputs. Reversely, when encountered, many people might not get what "DirectAN" stands for.

Other examples: accessibility (Q555097) → #a11y, Internet of things (Q251212) → #iot

By referencing those official or de facto hashtags, Wikidata could help jump in a subject and go straight to the relevant content -- Zorglub27 (talk) 11:53, 23 December 2015 (UTC)

Discussion
  • Oppose; hashtags can change on a daily basis. --Izno (talk) 17:54, 28 December 2015 (UTC)
it should be reserved for stable, well accepted hashtags obviously, such as the DirectAN example I was giving that is the de facto hashtag since 2010 from what I can see. Plus, some hashtags have already been accepted as entities. Alternatively, we could have a property to use those instances of hashtag (Q278485) as value, so requiring to change this propostion datatype. -- Zorglub27 (talk) 11:05, 29 December 2015 (UTC)
  •   Oppose If it is appropriate to link hashtags on Wikidata, then any hashtag which is connected to the item should be listed. It is not for Wikidata to determine which one counts as the 'main' tag. If one tag is prominent, you can use the ranking function to indicate this. Overall, I think hashtags might be appropriate, but sourcing and stability are major points of concern, as hashtags are generally defined by the user community and use changes regularly. I could be persuaded, but for now I oppose this as proposed. Josh Baumgartner (talk) 20:20, 6 January 2016 (UTC)
    • Many hashtags can be sourced, either to media coverage, or official web pages for an event (e.g. #Wikimania ;-) ), television programme, or similar. Indeed, the BBC often shows a hashtag in a caption, at the start of a programme. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 13:03, 8 January 2016 (UTC)
  •   Support. Though I sympathize with the discussion above, I believe that the usefulness of hashtags far outweighs the implementation work. 1) For some entities, like Black Lives Matter (Q19600530), hashtags define the group, its members, the related discussion, and up-to-the-minute events. 2) Researchers using Wikidata to get corpuses of text to train machine learning models would benefit far more from hashtags (lots of data) than just official websites (little data) or official social media accounts (a medium amount of data). 3) I don't necessarily think a String datatype is best; I think we should first make sure a hashtag is notable, assign it instance of (P31) hashtag (Q278485), and link from the relevant entity. This notability requirement would subsume the "stable, well accepted" requirement that Zorglub27 wisely noted. 4) Hashtags are one of the major forms of communication on multiple social networks; they're inherently useful to a large minority of Internet users. I believe Wikidata ought to reflect that. Runner1928 (talk) 22:01, 6 January 2016 (UTC)
  • changing the datatype to an entity and removing "main" from the label seem the be the right thing to do indeed, but should the property label keep the mention of "twitter" or could that be a generalist "hashtag" property? Should I edit the present proposition or edit a new one? -- Zorglub27 (talk) 12:09, 8 January 2016 (UTC)
    •   Comment Changing to an item will remove the utility of a formatter URL; but the individual item could hold a specific URL. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 13:03, 8 January 2016 (UTC)
    •   Comment Unless you see some benefit in having separate labels for every language or linking multiple items to the same tag, item datatype doesn't seem to be suitable for this.
      --- Jura 17:51, 11 January 2016 (UTC)
      •   Comment Ah, that's fair. I'll strike my suggestion for an item datatype. We should discuss whether this property should be Twitter-specific. Instagram uses the #hashtag style just like Twitter, and Pinterest and Google+ and Facebook all do too. Creating new properties for each site's hashtags would not only allow for easy formatter URLs but it would also allow us to differentiate between different hashtags on different sites but with the same meaning. E.g., #foobar on Twitter, #foo on Facebook, and #bar on Instagram might all mean the entity Q1. Either we'd need to differentiate using different properties or using one property with qualifiers or conditional formatter URLs. Runner1928 (talk) 15:58, 27 January 2016 (UTC)

@Micru: I at best see no consensus for inclusion of this property and at worst see consensus against inclusion. Why did you create it? --Izno (talk) 20:56, 1 March 2016 (UTC)
@Izno: The concerns raised were about stability of the hashtags, and those were addressed by only accepting sourced hashtags from official/stable sources.--Micru (talk) 09:11, 2 March 2016 (UTC)
@Micru: which are not guaranteed a) to be unique and b) are not guaranteed never to change in source. Official URL is susceptible to the same problem, but I at least can archive an official URL. I cannot do the same with a hashtag. --Izno (talk) 13:53, 8 March 2016 (UTC)
@Izno: There are no guarantees that they will remain stable, but they provide a source of information, which is specially relevant for some groups, some of them base their identity on the hashtag. Nevertheless we can wait until there are special cases, so far the property is not used that much. Regarding archives of twitter I found this, maybe it is relevant to your concerns.--Micru (talk) 14:27, 8 March 2016 (UTC)

Motivation

The culture(s) or people(s) associated with a geographical area, ancient site or find is a basic bit of information for which there is no appropriate Wikidata property. For ancient sites, this information is in 'cultures' parameter in the 'ancient site' wikipedia infobox, so is easy to import.

plural

   Not done
Descriptionplural of given item
Data typeString
Example 1MISSING
Example 2MISSING
Example 3MISSING
Motivation

Well, I don't know, how exactly to fill the template above, so feel free to mingle with it as necessary. Neither am I familiar with properties features, thus splitting the proposal to various ways according to the expected difficulty.

The easiest way:
String which is nominative plural of given item. (writer -> writers etc.)

The middle difficult (?) way:
As above, but with female complement as well. (host/hostess -> hosts/hostesses)

The more difficult (?) way:
All possible plurals according to the {{#plural:}} in given language. (eg. in cs, it is 0 spisovatelů, 1 spisovatel, 2-4 spisovatelé, 5+ spisovatelů)

The most difficult (?) way:
As above, but with female complement as well. (eg. in cs, it is 0 spisovatelů/spisovatelek, 1 spisovatel/spisovatelka, 2-4 spisovatelé/spisovatelky, 5+ spisovatelů/spisovatelek)

Rationale:
The initial kick for this proposal was desire for automatization of categorization. Example: (generic) infobox about person contains field occupation - that is (can be) taken from Wikidata. Then the appropriate categorization could be automatically done simply with using the plural (eg. people with occupation "writer" would go to the category "writers"), so there is no need to create huge local "database" templates or modules with key->value of singular->plural.
The plural forms is ATM rather forward-compatibility. Let's imagine some list of people, which would contain some summary like "This list contains 2 writers, 5 singers and 1 musician." or so...)

Possible limitation:
I'm not sure if it's worth to limit it to any particular scope, but as described above, the original purpose is about people, thus their occupation, but also nationality for instance (Category:Americans etc...) and I bet there will be others...

To consider:
Inverse property "singular" for items like Americans (Q846570) (Americans -> American).

    Differing rationales produce the same problems in implementation. You need to show that it will work, which you haven't and honestly probably cannot (though you tossed out a handful of suggestions). That's the reason it was opposed last time. --Izno (talk) 14:05, 8 March 2016 (UTC)
    What was earlier, egg or hen? You want me to create something, what I (as I clearly stated) want to avoid creating as it can be much simplier, more flexible and scalable crated here? (Well, I can, but I am sure, that the description is clear enough and there is no need to worthlessly spend time on creating key->value templates/modules to handle the desired feature just to show how it should not be...) The proposal clearly mentions the most common and most desired usecase - automatic categorization. For which the simple plural (preferably with female qualifier as well) is enough. Everything other is just a conditional benefit over it. If that really matters, I can delete those subsequent suggestions for grammar forms.
    Danny B. 14:41, 8 March 2016 (UTC)
  •   Oppose To give sense to this property you would need to store the plural form of labels in (20-200 languages) * (1-3 grammatical genders) * (1-10 grammatical cases) = huge number. Conclusion: this needs its own project, e.g. Wikidata:Wiktionary/Development/Proposals/2015-05. Btw are Wikidata items thought to represent real world entities and not entries of a dictionary. --Pasleim (talk) 14:18, 8 March 2016 (UTC)
    • Did you actually read the proposal? So let me correct your incorrect statistic equation: (n of languages - well, each property is all langs, right?) * (1-3 genders - so why there is a "female form" property then?) * 1 (the proposal mentions the simple plural as the desired minimal aim, the other is just a benefit). So no huge number. Single property of single for plural and then either qualifier for that one stating a gender or have the plural as a qualifier for the female form. Nothing huge, so please don't spread incorrect statements, thank you.

  • I agree that support for Wiktionary would be the best way to handle things like this, but that is still a long way off, so I would not object to a proposal which explains why the property is needed now and addresses the issues regarding support for other languages. However, I don't think this proposal does that. For categorising pages, we already have topic's main category (P910) (e.g. writer (Q36180) already has a statement topic's main category (P910) Category:Writers (Q5849863)), so I don't see any need for this property for that purpose. For creating summaries, that needs more than just a "simple" plural and the proposal doesn't address how we would store all the information needed to select the correct form. - Nikki (talk) 15:23, 8 March 2016 (UTC)

There is a frequently used template (esp. in German WP) (Vorlage:Archinform / Q6611520) for setting up links to archINFORM.net (International Architecture Database). Transformation of the data in the templates into Wikidata should be quite easy. Like for other authority data, therewiould be a need for several "archINFORM" properties (persons, places, key words, ...). On the other hand the archINFORM editorial staff maintains a own relation table for authority data. Maybe the following way would be a better alternative: The archINFORM authority property only contains a boolean value instead of a full archINFORM ID. The value stands for an existing relating entry in archINFORM. To get the specific archINFORM-page a Wikidata resolver, maintened by the archINFORM website is used. example: http://archINFORM.net/wikidata/Q123966 --Arch2all (talk) 10:48, 28 January 2016 (UTC)

ISO 15924 numeric codesome other languages

Template parameteriso15924 in en:Template:Infobox writing system
Domainscripts
Motivation

ISO 15924 defines two codes per script, an alphabetic code and a numeric code. Right now they are both covered by a single property, ISO 15924 alpha-4 code (P506). That seems awkward since it's harder to use the data (e.g. if you want the alphabetic code) and harder to make good constraints (e.g. an item should have two statements for the same property, one should follow one format, one should follow another). I think the property should be split, in the same way we have separate properties for ISO 3166-1 alpha-2 code (P297), ISO 3166-1 alpha-3 code (P298) and ISO 3166-1 numeric code (P299).

The alphabetic codes are almost always the codes that people refer to (they're also the ones used to make language tags, e.g. zh-Hant), so I'm proposing that we make a new property for the numeric codes, migrate the numeric ones to the new property and then restrict the current property to only the alphabetic codes, because I think that would be less disruptive than making two new properties and deleting this one. However, I would not be opposed to two new properties if people would prefer that.

I'm very surprised this doesn't exist already, as SSSI is a significant designation in the UK. SSSIs also exist in Wales and Scotland at least, but they have different formatter URIs as e.g. Wales is administered by Natural Resources Wales (Q6980600) not Natural England (Q1699627) and seems to use a three digit ID not a 7 digit reference, I haven't looked at Scotland.

Also, in the same way that position held (P39) will be used to track only the most noticeable positions held during a person's lifetime (such as a leadership position, or at least positions that would make a person eligible for an article on Wikipedia) rather than just any position they have held at some point, a property specifically labelled for membership in an executive branch is quite a different thing, in my opinion, from the generic notion of membership. Place Clichy (talk) 19:45, 3 September 2015 (UTC)
Why would it need to be a qualifier? Also, I don't think your understanding of position held (P39) is correct --Yair rand (talk) 13:18, 20 October 2015 (UTC)
  Question @Yair rand, Place Clichy: If I am understanding things right, this is for cases where a person holds an office/seat that is part of a cabinet. If these two claims are true:
⟨ John Prescott (Q332393)      ⟩ member of (P463)   ⟨ Deputy Prime Minister of the United Kingdom (Q1507619)      ⟩
start time (P580)   ⟨  Time period 'A' starts ⟩
end time (P582)   ⟨  Time period 'A' ends ⟩
⟨ Deputy Prime Minister of the United Kingdom (Q1507619)      ⟩ part of (P361)   ⟨ First Blair ministry (Q3112705)      ⟩
start time (P580)   ⟨  Time period 'B' starts ⟩
end time (P582)   ⟨  Time period 'B' ends ⟩
It can simply be inferred that during the time period where 'A' and 'B' overlap:
⟨ John Prescott (Q332393)      ⟩ cabinet search ⟨ Q3112705 ⟩
Doesn't this obviate the need for the 'cabinet' property, since it can be derived by query? Josh Baumgartner (talk) 22:07, 21 October 2015 (UTC)

  Comment @PAC2, Popcorndude: I would need more informations : is this some kind of datatype ? In computing or in maths, you define things like like x:Integer for example, which states that the X variable range over the set of integers. It seems to me that we here have a set of Social Security numbers and that actually the variable ranges over the set, which should be written in the previous notation, if we call the variable ssn ssn:Social Security number (Q5612679)     . Plus : this seems more appropriate as a qualifier for, say a column as a dataset. author  TomT0m / talk page 11:41, 25 November 2015 (UTC)
I would agree that it would be better as a qualifier, but I don't see anything for it to be a qualifier of.
If I understand your question correctly, the answer would be that we would not be giving the variable names, only the types.
Perhaps this would be better called "Statistical Variable Measured"? Popcorndude (talk) 12:33, 25 November 2015 (UTC)
  • I guess this is related to JHeald comment above and its proposition :
    ⟨ dataset item ⟩ "contains column" search ⟨ population (Q1613416) ⟩
    series ordinal (P1545) search ⟨ "2" ⟩
     : we need to think variables, quantity measured, variable names ... It seems also that we should be align with physics : for example we have units ( metre (Q11573)      ) with properties to link the unit to the kind of stuff it can measure
    ⟨ meter ⟩ measured physical quantity (P111)   ⟨ distance (Q126017)      ⟩
    . GDP is in $ or € or any money unit and is supposed to measure production (Q739302)     . What we want to express is that the dataset is about a set of countries, and contain a set of measures about each country, that measures beeing usually expresses using a certain unit ... How can we do that globally ? author  TomT0m / talk page 12:50, 25 November 2015 (UTC)
@TomT0m:, this is not datatype but really what is measured for each statistical unit. For instance, for a country, you may measure "population", "GDP", "GDP per capita", "area", etc. --PAC2 (talk) 14:22, 25 November 2015 (UTC)
@PAC2: OK, so with the assumption that one dataset can countain only one statistical units,
If the dataset format is for example CSV or similar tabular representation, then we would also associate a column number as suggested.

I noted this was apparently missing when expanding 1989 Loma Prieta earthquake (Q1053476).

It is also worth noting that damages (Q308922) is a similarly named but very different concept (also missing I think) which should not be added to this.

  Support right ascension and declination - those are definite standard astrophysical properties we should have, useful for every astronomical object (at least outside the solar system). Distance from Earth I'm not entirely sold on - should it be a more generic distance property with Earth as a qualifier? ArthurPSmith (talk) 21:56, 28 January 2016 (UTC)
A generic distance property (with mandatory qualifier relative to (P2210)) would allow for lots of arbitrary statements of distance from insignificant points of origin. Swpb (talk) 17:09, 29 January 2016 (UTC)
A generic distance property would be good (and the idea has come up a few times before), but I think if there's a large class of things which would all use the same qualifier, it would make sense to have a subproperty for it. That sounds like the case here, so I   Support a "distance from Earth" property. - Nikki (talk) 19:48, 9 February 2016 (UTC)
  Comment (s) from Mu301 (talk) 20:14, 5 February 2016 (UTC)
  1. The examples above give RA and DEC in decimal degrees, but HH MM SS.nnn and DD AM AS.nnn are more the norm and that is the current format for the {{Starbox observe}} template. The formatting should conform to what reliable sources use. While I support the RA and DEC in general, I strongly oppose decimal degrees as the units. It impairs readability of the numbers and is not what a professional astronomer would use in most contexts.[2]
  2. For many objects ly or pc works fine, but it breaks down for the most distant objects where it is difficult to convert from redshift to distance without a large error in magnitude. Also see the footnote to the table at [3] which correctly points out that for the most distant objects in the universe this value "has no direct physical significance". This causes problems for astronomical objects like BDF-3299 which give misleading information in the {{Galaxy infobox}}. If this is not used for extra-galactic astronomical objects it would be fine.
  3. Will "distance from Earth" cause problems outside the context of starbox usage? A generic distance from Earth could reasonably need a wide variety of units. For a planet it might be AU while a near earth asteroid might need a multiple of Lunar distance or even Earth radii (for a close approach) as this is what a reliable source would use. I think this should be narrowed from all "astronomical objects" to just those outside the solar system (but not objects at cosmological distances.)
@Mu301: Are you suggesting a string datatype rather than a quantity datatype? Or to try to create a new datatype for angular degree units? I think that's really unnecessary -I don't think there's any essential difference between HH MM SS.nnn and a decimal formulation other than formatting. String datatype might be ok but I'm a little wary in this case. ArthurPSmith (talk) 21:13, 5 February 2016 (UTC)
@ArthurPSmith: I have a few concerns. One is that someone entering data manually will consult a source that gives HMS and there will be transcription errors when converting to decimal. Another is the display of significant figures. In the example[4] above the RA for the Crab Pulsar is given as 05 34 31.93830. Notice the significant trailing zero in the decimal portion of the seconds. The number of digits in a decimal representation should be equivalent to that precision. I'm not terribly concerned about how the data is machine readable formatted but it should render prettyprinted in an infobox. This is how sources represent the data in the majority of cases and it is what an astronomer (amateur or professional) would expect to see. Decimal RA would be like using JD 2457423.5 for today's date in my signature. It is a perfect choice for a computer program, but not very user friendly. But to answer your question I do think this warrants an angular data type as this is common usage in the field. It's not really a string of characters but a specific formatting of a numerical value. The w:IAU Style Manual specifically notes the common use of base 60 coordinates but only encourages decimal in examples like "formulae for numerical calculations." Readability is part of the reason why scientific publications use this style. --Mu301 (talk) JD 2457424.407639
Regarding #3, the quantity data type allows any units, so different units isn't a problem. - Nikki (talk) 19:48, 9 February 2016 (UTC)
Since the directions are relative to the celestial equator, which is Earth's equator projected onto the imaginary celestial sphere, it is consistent to express the distance as the distance from Earth.
About precision, for latitude and longitide, an unresolved controversy is whether there should be lossless conversion of units. For example, if I enter the RA of the Sun as I write this, from the Multiyear Computer Interactive Almanac, as 21 h 38 m 06.068 s, and someone wants to convert it to decimal degrees, the proper conversion from an engineering and science point of view would be 324.52528°, or maybe 324.525283°, because further decimal places are not justified by the precision of the number being converted from. But some editors want to use the full precision allowed by the data type, which according to the data model is 9 digits after the dot. In this example that would be 324.525283333°. This approach would give the greatest chance of lossless round-trip unit conversion, but misrepresents the precision of the number when the unit is degrees.
I believe we should state that the number of digits should correspond to the precision of the source, no matter what units are used, and lossless round-trip unit conversion is not a goal.
Do notice that when RA is expressed with minutes and seconds, it is usually expressed in hours, minutes of time, and seconds of time, not degrees, arcminutes, and arcseconds. Jc3s5h (talk) 17:01, 11 February 2016 (UTC)
Yes, it is important to note that RA is not merely just an angular unit. It is both angular unit and also a sidereal time (of the moment the star crosses the meridian.) The setting circles on telescopes use degrees arcminutes arcseconds for DEC and hours minutes seconds for RA. I'm not as concerned with how the data is internally represented in degrees or hours as long as the infoboxes that pull this data render RA as HH MM SS. I'm more a proponent of using precision that conforms to sources without padding. --Mu301 (talk) 17:37, 12 February 2016 (UTC)

The Pocket Guide to Chemical Hazards include a list of analytical methods that can be used to determine the presence and concentration of chemicals. The Pocket Guide refers to ID numbers of analytical methods published in the NIOSH Manual of Analytical Methods (Q21757411). I have created items for each of these methods and plan on modeling the relevant data on Wikidata and transcribing the text of this manual on Wikisource. I originally considered using determination method (P459) but I believe that property is meant to be used as a qualifier, plus it's confusing: chemicals don't have determination methods; their concentrations have determination methods.

  Weak oppose This not really a property of a chemical and this depends on too many parameters like solvents, concentrations or contaminants. I prefer to use the identifier to link to the web page and to be able to recover that information there instead of importing all the stuff in WD. I think WD is not a compilation of all data especially when we speak about complex processes. Snipre (talk) 10:53, 14 January 2016 (UTC)
Snipre, the goal of the property is not to describe the entire analytical process within the statement, or even within a dedicated Wikidata item. Rather, the goal is to link a chemical with a specific method, which has a Wikidata entry that corresponds with a Wikisource entry. The Wikidata entry will contain some basic structured data but most of the complex information would be on the Wikisource page. Do you have alternative recommendations for associating an analytical method item with the chemical(s) the method is designed to measure? James Hare (NIOSH) (talk) 13:57, 14 January 2016 (UTC)

I ended up encoding these values by going to the individual items and saying they are instances of analytical technique in the scope of chemicals {X, Y, Z...}. It'd be nice to have this information going in the other direction as well (chemical to method, rather than method to chemical), but I suppose this property is not all that necessary at this point.

Help scoping a lot of items and linking object to their sciences. A lot of structuring power, a help on automatic item disambiguation, a help on scoping Wikipedia article who sometimes mixes the two subjects. Can potentially help restoring lost interwikis : if some Wikipedia has an article on the science and the other one on the object, the interwiki language link might have been lost, as this is a common pattern a custom template can propose a link to the Wikidata item and redirect to the corresponding article in the other language.

This is not "part of", it would be more like has part (P527), but I do not think it is exactly that either. I support the idea, but as a general rule, I think it should be used only with more generic values. If "number: subclass of: mathematical object", and "mathematics: study of: mathematical object", then it does not seem necessary to add "mathematics: study of: number" (else where do we stop ?) --Zolo (talk) 16:03, 14 October 2014 (UTC)
@Zolo: I just took the statements from the Wikipedia articles. Study of numbers is a pretty common definition of maths, so there is no harm, and numbers (or sets in maths foundations) can pretty much the starting point to encode any other math objects. So it's just a matter of choice, there is no problem with beeing somewhat redundant if their is no contradiction, it's not a big deal. And it's just a detail, I think it's important to link a science to the type of concept it studies (way more) :) TomT0m (talk) 11:43, 21 February 2015 (UTC)

@Succu: I can't tell if microscopy (Q1074953)      is the study of the microscope themselves or what's looked at, I'm sorry. We got a problem of definition with maths. If maths are a set of knowledge about abstract object, like logics or theorems, then yes I's say we can use part of. If maths are the process of finding or studying knowledges about those objects, then this property fits. That's the first sentence of the enwiki article : Mathematics (from Greek μάθημα máthēma, “knowledge, study, learning”) is the study of topics such as quantity (numbers),[2] structure,[3] space,[2] and change.[4][5][6]. I'm not sure about the vice versa thing, what's important is to make a link. But I think a science item should link to the objects it is about, it's a defining property of a science. On the other hand it's not a defining property of the stars to be studied by astronomy, there was stars before astronomy and there probably be stars after ... TomT0m (talk) 17:31, 4 July 2015 (UTC)
I think it's more convincing to say
⟨ celestial body (Q1519541)      ⟩ is/are studied by search ⟨ Q333 ⟩
⟨ star (Q523)      ⟩ is/are studied by search ⟨ Q333 ⟩

⟨ astronomical object (Q6999)      ⟩ is/are studied by search ⟨ Q333 ⟩
If you use study of you end up with a very long (uncomplete) list. --Succu (talk) 18:31, 4 July 2015 (UTC)
@Succu: It's more effective to keep the wording as is and stay with a rule : if celestial objects is studied by astronomy, then any of their subclasses is studied by astronomy. That way we keep only the most general statements an your problem vanish. This is already implied by the subclass relationship anyway, as planets are of course astronomical objects. I don't think that the is studied by inverse property is better in that matter, because you would just end up with an endless and incomplete list of redundant statements localized anywhere on the items in the subclass tree ...

  • Isn't this redundant to office contested (P541)? --Yair rand (talk) 11:46, 14 October 2015 (UTC)
    @Yair rand: Maybe, maybe not. I note that this property is used to link a specific election to a kind of office, whereas that one is to link a type of elections (with the fact that any instance of the election's office contested (P541) statement will be redundant with the property I propose, actually. I was not aware of this property, but anyway there is a real question on whether or not we should have different properties when the domain is the class or when the domain is instances of some class. author  TomT0m / talk page 11:54, 14 October 2015 (UTC)
    Having a property for class, do we need a property for instances at all? Wouldn't a re-definition of office contested (P541) as a class-property do the job? --Shlomo (talk) 12:54, 14 October 2015 (UTC)
    Good point, that may be more relevant when some kind of reasoning feature will be intergrated to Wikidata (see WikiProject Reasoning). One problem I can see with that approach is the change in time problem, where it needs some thinking on how to well reflect changes in elections modes and so on ... Either this would need to have a new item for historical elections class for each change in the elections, or qualifiers for validity of claims about the properties of the election with good way to handle the inferences on old elections on infoboxes to avoid anachronisms. author  TomT0m / talk page 13:00, 14 October 2015 (UTC)
  •   Comment To me, the link between Q3587148 and Q375928 seems rather random. Do we really need this? What would it allow you to do? --- Jura 13:25, 14 October 2015 (UTC)
    Good point. I didn't notice the example, which shows a use of this property to connect it to a class, not an instance of a political office (or, as in this case chamber). If this is TomT0m's intention, it should be made clear also in description. In that case, it's not redundant with office contested (P541) at all. But then Jura1's question is fully legitimate: Is there a need for such a property?--Shlomo (talk) 14:14, 14 October 2015 (UTC)
    @Jura1, Shlomo: What do you mean random ? Oh, ok I guess I made a mistake and got lost into the maze of items, I meant French National Assembly (Q193582).
    The starting point of all of this is a discussion with Schlomo on the meaning of one item. is to define some classes of elections. This is totally a characteristic of a type of elections to know what's their purpose his. We don't actually have a lot of properties to describe an election which will allow to identify an item with statements, so unambiguously in all languages. Statements are the root of international communication on Wikidata. We have to be able to describe the items to enhance communication on Wikidata by making Wikidata more expressable by itself and serve as a common and expressive international language. author  TomT0m / talk page 14:27, 14 October 2015 (UTC)
    Another symtom that this it's useful : the discussion above demonstrate a huge power to reduce redundancy ... author  TomT0m / talk page 14:29, 14 October 2015 (UTC)
    After making clear the example was a mistake and after it's correction my question here is not relevant any more. But we have to solve the redundancy issue above...--Shlomo (talk) 14:54, 14 October 2015 (UTC)
    • Clear samples and usecases can enhance communication as well. Would you provide a usecase as well? How you plan to use it, what statements you would be adding? Somehow I think Q3587148 should be a disambiguation (or a history of .. item). --- Jura 15:07, 14 October 2015 (UTC)
    • Well, a history of ... "legislative elections in france" ? This is quite autoreferent :) The article about of a class of events is perfectly legitimate to be described by a history of this kind of events, together with a description of how the elections is organized, who votes, ... . Usually an item or an article have a subject on their own. Example of such items United States presidential election (Q47566) French senate elections (Q3587541) You'll remark that this items includes indeed a history, but at first they describe how such events are organised, who vote in this kind of vote, ... This is the formal definition of a class of events. Any event in a class of events shares some properties who are defined by the type of elections in our case : they take place a period of time after the preceding of the same kind, a type of people are allowed to vote (the same kind at each vote, except if the rule changes), the role of the elected people, who can compete ... The similarity beetween a formal definition of a class in math (a collection of object who shares some properties formally defined) justifies the fact that they are classes of events (periodical events), classes of elections, because all events of this kind are elections, and so on. The three properties I proposed aimed to reflect somehow the resume of each article and express the definition in a structured way. This is why this allows to reduce redundancy, because by classifying all elections in this classes, we don't have to repeat what they have in common (any president of the united states elections elect a president of the united states). By saying this is a property of all the instances of this class, you don't have to repeat it for all the instances. author  TomT0m / talk page 15:32, 14 October 2015 (UTC)
    • And your usecase in terms of data extractions as well as the statements you plan to add are? --- Jura 15:43, 14 October 2015 (UTC)
    • Beeing able to express useful things about an item when I occur them that are useful to describe a kind of pretty common items is useful for me. No, I don't have a ready made database of elections. I just know it's properties for a kind of elections that will help to define such items. Enough of a usecase for me. The expressivity of Wikidata is an important goal by itself. Filling the data is another step. Why would not that be enough ? author  TomT0m / talk page 15:48, 14 October 2015 (UTC)
  • Another point to clarify is the case of parliamentary elections: Shouldn't the statement point to the office obtained by particular candidates (in the sample case probably member of the French National Assembly (Q3044918)) rather than to the whole chamber?--Shlomo (talk) 14:54, 14 October 2015 (UTC)
    • I don't know whats best, but I tend to think it's best to link to the chamber as it's an election where there is a set of "circonscription" and that there is one "député" office for each circonscription. I'd say this election as several election parts, each of his parts designate a député, for example
      ⟨ législatives circonsription Nantes 1 ⟩  Wikidata property  ⟨ député Nantes 1 ⟩
      with
      ⟨ député Nantes 1 ⟩ subclass of (P279)   ⟨ député ⟩
      . author  TomT0m / talk page 20:05, 14 October 2015 (UTC)
      This seems to me to be to complicated for practical use. Besides, it could work for French National Assembly, but other elections have "circonscriptions" (=probably "election districts" or "divisions") with several or many mandates for each. Some of them have just one division and one ticket for all the voters. And finaly, the structure of divisions and method of assigning mandates to divisions can change far more often than the basic principles of the election do - since usually they aren't fixed in constitutions, just in regular acts or edicts.--Shlomo (talk) 20:48, 14 October 2015 (UTC)
      • This depends on the level of precision we can afford to attain, but usually results of elections are public and published, so it might be of some use to import them on Wikidata. Actually this seems not really difficult to automate in an OpenData perspective, so no, I don't think this is too complicated for practical use. It's a question or regularly importing the published spreadheets "en masse". I maintain furthermore that it's not the same when a national election is runned for a single office like the presidential election than when a ational election is aimed to elect an assembly of persons. If we want to map an election to an office, we should find a way to say that the number of offices in the game in the whole election, maybe something like
        ⟨ election ⟩  Wikidata property  ⟨ deputé ⟩
        quantity (P1114)   ⟨ 3xx ⟩
        would work, but we lose the link to the assembly, who is interesting as well. author  TomT0m / talk page 10:38, 15 October 2015 (UTC)
  •   Oppose Elections are for specific offices. If those offices are part of a body, then that body can be determined through querying the office, and does not need to be directly linked to the election. The same is true of a class of elections with instance elections that are for offices that are part of a body. It may seem illogical that French legislative elections (Q3587148) is not directly linked to French National Assembly (Q193582), but that link in reality is established through the contested office. Josh Baumgartner (talk) 17:01, 28 October 2015 (UTC)
    @Joshbaumgartner: Can you provide an example ? I don't think you understood. I do not want to link to a specific election instance but to the "Type of" elections. author  TomT0m / talk page 11:32, 15 November 2015 (UTC)
@TomT0m: Certainly, you are proposing
⟨ French legislative elections (Q3587148)      ⟩ type of election for search ⟨ Q193582 ⟩
, but that link is already established:
Thus, through this query, one can determine that French legislative elections (Q3587148) is held to elect members of French National Assembly (Q193582). Josh Baumgartner (talk) 20:38, 16 November 2015 (UTC)
@Joshbaumgartner: This is a weak modelling anyway. We don't know there is several deputies office, this might be an election of a president as well. The election is a composite one. This is an assembly that is elected by that election, not a single person ! author  TomT0m / talk page 20:49, 16 November 2015 (UTC)
@TomT0m: I get that, but it is still derivative is my point. The election elects members of French National Assembly (Q193582), not French National Assembly (Q193582) itself. French National Assembly (Q193582) is not a type of election, it is a legislative body, so it can't really be used as a 'type of'. Maybe if you had an item 'election of the French National Assembly' it could be a type, and fit, but it would seem redundant at that point. As for the president, they are elected by a separate election held prior to the legislative one, but even if not, it wouldn't change how the query would work. Josh Baumgartner (talk) 21:10, 16 November 2015 (UTC)
@Joshbaumgartner: Actually we have such that item, and its the subject of the claim, we reversed the sense of the property during the discussion. My point is an election is actually for the whole chamber. And the whole point is to link the type of election to the chamber it's used to designate ... It is a direct translation of the laws about the chamber. author  TomT0m / talk page 21:21, 16 November 2015 (UTC)

As Pasleim notes, organizations can have a huge number of assigned address ranges, separate for each office and data center location.

    • I changed the label "Foreign exchange rate" to "currency exchange rate". I also removed the reference to "USD" in the description. --- Jura 12:18, 11 September 2015 (UTC)
  • How often Global Economic Map Bot could update values? What a source of data it used?

  •   Comment @Mcnabber091, Zolo, Bezik: given the way units are defined, we could use number datatype with items like USD/CNY (Q20965809) as units. Don't forget to add a point in time (P585) qualifier. --- Jura 10:51, 11 September 2015 (UTC)

  •   Oppose. Remember that this property will be used to make statements abouut a currency so you already know what the 'first' currency is. The value for this property should be the value of one unit of the subject item. Change the label to "Value in USdollars".

  • You are right. It is. See better proposal below.Joe Filceolaire (talk) 22:51, 6 October 2015 (UTC)
  •   Comment. After some thought, I think we should have both (B) and (C):
    • (B) as a qualifier "exchange rate used", to qualify how specific statements have been converted. This can be done at a later stage.
    • (C) as a property with item-datatype (to link currencies to their pair items). Below the relevant proposal. This should make it easier to assess/create. --- Jura 17:20, 23 September 2015 (UTC)
  Comment. Get rid of USD/CNY (Q20965809). Burn it to the ground then let it fall into the swamp. "6.18 USD/CNY" is meaning less.
'United States dollar (Q4917)' <Value: 6.18 (units=renminbi (Q39099))> makes complete sense. 'renminbi (Q39099)' <Value:0.16 (units = United States dollar (Q4917))> does too. No problems with which way the exchange rate is expressed. No preference for one currency over another.
This is how you should handle exchange rates, in my opinion. The property you want to create is a property to make claims about the value of the current item. Joe Filceolaire (talk) 22:51, 6 October 2015 (UTC)
Sure, if you want to give it I try. Ok for me. --- Jura 10:12, 27 October 2015 (UTC)
