standard unit

   Not done
DescriptionStandard unit for the quantity measured by this unit
Data typeItem
Domainunit of measurement
Allowed valuesunit of measurement (Q47574)
Examplemillimetre (Q174789) → metre (Q11573)
Motivation

In order to be able to process or query quantities with units, it may be necessary to bring them to the single unit. I.e. some distances can be expressed in kilometre (Q828224), some in mile (Q253276), weights in kilogram (Q11570), some in ton (Q11247037), some in pound (Q100995), which are not directly comparable but can be converted to common measure. It would be nice if for automatic processing we could specify that all metric length units should be converted to, say, metre (Q11573) - then every unit with standard unit marked as metre (Q11573) would be automatically recognized by tools as belonging to the same family and automatic processing of such quantities would be much easier.  – The preceding unsigned comment was added by Laboramus (talk • contribs).

Discussion
  •   Comment see #conversion_to_standard_unit above. --- Jura 15:41, 10 September 2015 (UTC)
    • Yes, similar, but not the same. You It would be more complex to ensure all length properties have the same standard unit without having dedicated property - i.e. if somebody says that yard is 36 inches, it may be non-trivial to figure out whether inch can be converted to meters. Having this knowledge explicitly would allow to scan for it and have bots or people enforce proper conversions more easily. That said, I support #conversion_to_standard_unit and if the majority things two properties are redundant, we can do with just one. --Laboramus (talk) 22:51, 10 September 2015 (UTC)
      • We should not be calculating conversions and storing the results of those calculations in Wikidata, as that would be original research. We should only be listing conversions when they are cited in source material, and as such what we list should be exactly as listed in the cited work. Josh Baumgartner (talk) 21:00, 5 January 2016 (UTC)
  •   Oppose. I expect the "number with units" datatype to deliver this automatically - i.e. all lengths should be stored internally in meters, no matter if the value is in inches or Angstrom, so all are comparable. If they fail to deliver then we can look at this again. Joe Filceolaire (talk) 15:06, 12 September 2015 (UTC)
That’s not how it works. A number with units is just a Quantity (value, minimum, maximum) and any item as unit – doesn’t have to be a number. —Galaktos (talk) 16:15, 12 September 2015 (UTC)
I think it's a bit different proposal but equivalent to what I proposed, only applied to measured quantities instead of units. Maybe we need a separate proposal for that... --Laboramus (talk) 08:11, 12 October 2015 (UTC)
  • "Base unit" has a specific meaning in the International System of Units; derived units are expressed in terms of base units, and some derived units have special names. For example, force is expressed in kg²⋅m / s² and one may use the special name newton for this derived unit, if one wishes. It would be confusing to assign a different meaning of "base unit" in Wikidata. Jc3s5h (talk) 20:43, 24 September 2015 (UTC)
  • If, for example, we wanted to have a unit to which every power measurement should be converted, we might choose the watt. But the watt is not an SI base unit, it is a SI derived unit with a special name. Jc3s5h (talk) 17:42, 23 November 2015 (UTC)
  •   Oppose We should not be deciding what unit is 'standard' for a measurement (such as 'mass is measured in grams'). I would be fine with an 'SI base unit' but it would only be those defined as such in SI and thus only apply to SI units and have no inherent relation to other measurement systems (ex: 'milligram' > 'gram'). We also should not be doing any conversions, all we should record on Wikidata are measurements and conversions recorded in cited sources. Josh Baumgartner (talk) 21:00, 5 January 2016 (UTC)
  •   Oppose A table on the Wikipedia side can do the job without all that stuff. To get feet from millimeter I don't need to first convert into meter and then into feet, I can directly convert using a table. Snipre (talk) 17:14, 19 January 2016 (UTC)
    @Snipre: This is not the point, this is a way to store the coefficient you would use in that "table" (btw. it's a calculation, not a table). author  TomT0m / talk pageé
    ;TomT0m I think this is the point: I can create a table with relation X mm = X*0.00328 feet and X m = X*3.28 and no X mm = X*3.28*Y feet where Y is your coefficient 0.001 for mm and 1 for m. My table will be bigger but I don't need to recover several parameter like the coefficient or the relation between mm and m. Snipre (talk) 17:00, 21 January 2016 (UTC)
    @Snipre: You can always harcode as many conversion you want in your code, with or without this. However if you encounter a unit you are not aware of, you won't be able to do nothing without couching your code. With that information in Wikidata, we can build more generic code which will be able to convert to "meters", for example, any length unit that can be expressed in meters, back and forth. author  TomT0m / talk page 17:17, 21 January 2016 (UTC)

This is a key property of toll bridges, tunnels, toll roads, etc. these change over time so this should be accompanied by a qualifier noting when it applies/ed.

  •   Oppose Fee, fare, and toll are all payment descriptions that may represent different concepts within particular situations, but overall are more or less interchangeable. In any case, the differences are not significant enough to require a separate property. Thus I support a single 'fee' property that covers it all (see 'toll' proposal above).

DEFAULTSORT

   Not done
Description
Proposition at languages level
At the end of definitions of the properties there are tables of links from Wikidata to other wikis.
We can add to each of these links a DEFAULTSORT field, with a priority mechanism described below, which is valid only for this couple of wiki + language.
If a lastname and 0 or 1 firstname is defined, the DEFAULTSORT 1 is "lastname then firstname". For other elements than Person this sort is the consensual one.
If a check box "firstname then lastname" or "reverse order", DEFAULTSORT 2 is the "reverse order" and overrides DEFAULTSORT 1. For other elements than Person this sort would be a switching between two simple options.
If a user has defined the DEFAULTSORT 3 is the text "value provided by the user" and overrides DEFAULTSORT 2.
The eventual future regional-sort can not use this option DEFAULTSORT 3 to not disturb the sorting in the main language.
Details in the Wikidata side, as source of DEFAULTSORT
For each packet (element + language + wiki), there is a group of options DEFAULTSORT 1 to 3.
An interface to get the DEFAULTSORT options of a category is available in all wikis for templates and in Wikibase Client/Lua.
Perhaps another interface to remotely define the DEFAULTSORT options of each packet (element + language + wiki) must be in the Mediawiki configuration of each wiki and could be in Wikibase Client/Lua.
Wikidata could also use the DEFAULTSORT property as client to sort its own categories or a part of them.
Details in the wiki side, as client of Wikidata
Each wiki can activate or not its client of DEFAULTSORT property, and activate or not the DEFAULTSORT property in each category.
In each category where DEFAULTSORT property is active, but bad defined, an error is displaid and one other alerts local admins.
Each wiki must chose a default packet (element + language + wiki).
Each category can change all or only some part in the wiki paquet definition.
Each user can chooses its own language to sort all categories of a wiki.
The priority level for the sort language is the item, else the user one, else the category one, else the wiki one.
If the priority change is partial, it can change other part of the paquet definition.
Data typeString
Template parameternone, for categories only
DomainPerson or any sortable items of the string type
Allowed values{ "normal", "reverse", "result", "regional" } + result + ( regional-sort-code in eventual future )
Example{{DEFAULTSORT|normal}} → {{DEFAULTSORT|reverse}} → {{DEFAULTSORT|result|De Magon, Ricardo}} → {DEFAULTSORT|regional|cyrillic-en|Ovechkin, Alexander}}
Format and edit filter validation1 to 3 strings following allowed values and options DEFAULTSORT 1 to 3
Robot and gadget jobsA bot to prepare the activation of new client wikis, collecting sort orders in many categories, before activation, could help to automatize the DEFAULTSORT definitions of packets (element + language + wiki).

This proposition answers to previous limits:

  • we get a new sorting property that works
  • specify the sortkey to be used for each language/script combination
  • sv.Wikisource and sv.Wikipedia do not use the same alphabet
  • easier to select the correct sortkey than monolingual string-datatype
  • The defautsort key is language-dependent
  • It should be handled with labels, not as a [simple] property.

--Rical (talk) 21:50, 13 January 2016 (UTC)

Motivation
  • Base of Wikidata: do once in Wikidata a shared task or service.
  • Propose an implementation to answer to a several times sought property.
  • Automatize the collection of existing sorting options paquet from many wikis.
  • To correct errors, detect sorting differences for one item, in 1 category when other(s) are equals, with the same options paquet.
  • Centralize the knowing and the know how to enhanse them.
  • Build an enough fiable robot able to propose a DEFAULTSORT and a right method in many new cases.
  • Offer a sorting service for any mediawiki wiki, in or out of WMF.
Along and across the automatic collection
  • Detect the differences in the value of SORTKEY, and the difference in the method to get the SORTKEY, the minimal options paquet to do the same.
  • To correct errors, see behind.
  • When detecting differences, search regularities inside exceptions in differences of method.
  • Build an enough fiable robot able to propose a DEFAULTSORT and a right method in many new cases.
  • Try and evaluate this robot after enough categories importation, when importing sort options from other categories.
Types of categories to compare
  • differences of projects: Wikipedia / Wikisource ...
Example: Swedish sv.Wikisource and sv.Wikipedia do not use the same alphabet.
  • differences of subjects: Biologists / Authors / Sculptors / Streets names / Genealogic research out of WMF ...
  • differences of countries: British / USA, Australia / USA, Canada / France, Maroco / France...
Example: France use "Van Gogh", Canada uses "Gogh, Vincent". See in VIAF.
  • differences of languages: foreing languages adapted in local language, like: cyrillic / cyrillic-en (cyrillic names modified in english).
Example: The transcription of the Cyrillic alphabet varies from one language to another.

The correct way might be a link to formatting template, which contains something like {{PLURAL:{{{1}}}|страница|страницы|страниц}}.

Motivation

This is being proposed as part of deleting/splitting comment (DEPRECATED) (P2315). Please see Wikidata:Properties_for_deletion#comment_.28P2315.29 for more information.

This was previously proposed at Wikidata:Property_proposal/Archive/44#property_usage. There were two reasons I can see for opposing it. The first reason being that the description field is sufficient. That is not true, it works when editing Wikidata directly, but it is inappropriate to include usage instructions in descriptions when showing descriptions in other contexts, see phab:T97566. Secondly, it was opposed because it was already covered by comment (DEPRECATED) (P2315). That is also not really true, the original description was quite vague and then the description was changed to be about usage instructions, but that is not what the property was intended for.

Ideally this property would be shown in search results when editing Wikidata (which is one of the suggested solutions to phab:T97566) so that usage instructions no longer need to be included in descriptions.

Motivation

This is being proposed as part of deleting/splitting comment (DEPRECATED) (P2315). Please see Wikidata:Properties_for_deletion#comment_.28P2315.29 for more information.

This property would be a generic comment property for people to add comments to things and would replace all the current uses of comment (DEPRECATED) (P2315), other than those which are usage instructions.

Although I'm proposing it, I don't actually support it for the reasons I gave in the deletion request, it's far too vague and we don't know what the comments are for nor who they are aimed at.

I think that in most cases, if people want to add generic comments about an item, the talk page would be sufficient. For cases where people want to narrow down the meaning of a statement, appropriate qualifiers should be used (or proposed, if there's nothing suitable already). For cases where people want to add custom edit summaries, while that isn't currently possible (see phab:T47224), I don't think it's appropriate to store those as part of the item's structured data anyway.

  •   Oppose the correct usage of this property is too unclear. Anything that might be written in here would be better expressed through a more specific property (and if the right property doesn't exist, propose it).

Aarne-Thompson classification systems are used to classify folk tales. The system is used in comparative folkloristics to identify some 2500 basic plots. I believe the expanded Aarne-Thompson-Uther (ATU) classification would be preferred to the old AT system, though it could be advantageous to be able to accept either. gobonobo + c 01:35, 3 February 2016 (UTC)

  •   Support This is a global standard. I will follow up with a few notes which may be useful to property implementers. Phil wink (talk) 04:35, 3 February 2016 (UTC)
    • Although, as I understand it, "Aarne-Thompson-Uther grouping" is unambiguous, "Aarne-Thompson grouping" might refer to 2 distinct indices: (1) the Aarne–Thompson Motif-Index or (2) the Aarne–Thompson Tale Type Index. It is the update to #2 which we're talking about here. So just to be explicit it may be best to re-name this property Aarne–Thompson–Uther Tale Type Index.
    • We are right to use ATU (the new standard), but I think we are justified in porting A-T numbers (the previous version) directly into this ATU property. It is intended to be "backwards-compatible", and my understanding is that it almost totally is.
    • The ATU index is organized hierarchically. I'm not sure this is easily managed in Wikidata structure; however I'll include here the keyed tables I'd use if I were setting this up as a relational database (this comes from the outline at Multilingual Folk Tale Database noted above, but normalized). The actual ATU values we'll be storing in this property would constitute "Level 4" (not tabulated). Maybe someone can make something of this... Phil wink (talk) 05:00, 3 February 2016 (UTC)

Discussion
In nearly all cases in German Wikipedia the GWP is given for 100 years. But for completeness I added also the 20 years value.
If every duration would be possible, of course the qualifier approach would fit better. Because of the benefit of much easier querying I would urge to create two properties here.--Kopiersperre (talk) 23:37, 31 January 2016 (UTC)
  Support I support this property but I agree with Thryduulf that there should be a generic property Global warming potential, for which the duration is specified as a qualifier. As many GWPs are given for 100 years, it might be possible to create a sub-property which already has the duration 100 years embedded. But I would add this generic property rather than another specific GWP for 20 years. --Jtuom (talk) 11:29, 2 February 2016 (UTC)

There is a new data type 'Mathematical Expression'. In contrast to the property 'TeX string' (which is just a plain string) the new data type comes with a validator to permit formula input only. And it includes a formatter to show the formula rendered (by MathML) and not as plain TeX code.

TeX does not fulfil that function since it parsing it is more complicated and in general needs knowledge of TeX formatting to be understood.  – The preceding unsigned comment was added by 141.23.124.250 (talk • contribs).
    "Already existing support for TeX is irrelevant," is an unsubstantiated claim. It is entirely relevant.

    "I want" The key phrase, because "need" for a suitable string providing the formula of a particular conversion (or otherwise) has already been provided for in the use of TeX.

    "easily retrievable" Regardless these strings are "easily" retrievable.

    "[easily] parsable" may be the only interesting concern. But already I see an issue: "()" are not provided for in the proposal (c.f. a / (b + c)). How many other "easily parsable" characters are missing from the set? Underscore is certainly one; what happens with the need to differentiate between two speeds (as in Mach number (Q160669))? How quickly does that set increase to "not parsable anymore"? Lowest common denominator doesn't work.

    "calculated with" I presume proper TeX can provide this as well, so the point seems irrelevant.

    "somewhat humanreadable." doesn't seem like a huge concern, whatsoever. For the operators provided, there are suitable TeX, none of which can be said to be particularly not-human-readable. --Izno (talk) 13:06, 12 January 2016 (UTC)

  • Maybe we could try to focus on assessing the user's need rather than pick on their wording or formatting .. I'm sure everyone loves TeX, but maybe there are other options. Possibly the new formula datatype can cover some of it, but it is essentially TeX based.

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)
Yes, I believe this is correct (see en:Solar eclipse of August 11, 1999#Notable times and coordinates for example. I will ask someone more knowledgeable to comment here. MSGJ (talk) 09:52, 29 April 2015 (UTC)
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)
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.

Why not just use inception (P571) ? Jheald (talk) 17:26, 14 September 2015 (UTC)
inception (P571) is too broadly interpreted. It could be the start of production, or even the first time the work emerged as a concept. Josh Baumgartner (talk) 21:20, 14 September 2015 (UTC)
  Oppose Production covers a span of time (we do not currently have a data type for this). As I understand it, the 'production date' generally cited however is the completion of the production. If this is indeed the intent of this property, it should be re-labelled and described accordingly: date upon which production of a creative work is completed or some such. Additionally, the domain should be work (Q386724) as there are several subclasses of this that this could apply to as the completion of creation as distinct from the point of release/publication/broadcast.

Imho we need this property for all subjects. (What would be the advantage of having a separate property only for persons = biographies?) Of cause the referred work should be "notable" in the meaning of presenting essential information about the item. --Kolja21 (talk) 20:41, 23 January 2014 (UTC)
How about "Book/article about subject" then? The problem with "Further reading" is that it may look like it invites to non-notable information or spam. I guess some projects have good guidelines about how the header "Further reading" should be used, but they are exceptions. -- Lavallen (talk) 11:59, 24 January 2014 (UTC)
"Book/article about subject" would be a good description. I've added it to the title. --Kolja21 (talk) 21:37, 24 January 2014 (UTC)
I would oppose this as the inverse of main subject (P921). --Izno (talk) 13:38, 24 January 2014 (UTC)
"Subject heading" is much broader. A book can have a dozen subject headings. "Further reading" (I try to use the same terminology as WP) should only contain the main works about an item. Take for example Boston University (section Further reading). It only contain 4 works but there can be hundreds of articles and books in WD with the subject heading "Boston University". --Kolja21 (talk) 21:48, 24 January 2014 (UTC)
  Comment Would statement is subject of (P805) work for the use case cited in the proposal? Emw (talk) 13:57, 24 January 2014 (UTC)
Good question. P805 is used in North Macedonia (Q221) and other items in a different way (not for literature). The German description "Datenobjekt über das Thema der Aussage" is hard to understand and needs further explanation. --Kolja21 (talk) 21:37, 24 January 2014 (UTC)
Let me understand: this would be a property for indicating the main works about a topic. It is thus different from the References or Bibliography on Wikipedia, right? Ths bothers me a bit, as, even so I understand the usefulness of such property, it would be very nnNOPV and it would not be decided in the Wikipedia page. I mean: the Wikipedia article is the place where there is the discussion and the creation of the article about the topic. They discuss and create the References section and the Bibliography section. Even that is extremely delicate, as you could really go nnPOV. But having a Further reading property just in Wikidata, disconnected by all the sections in Wikipedia, seems to much to me. Wikidata has a really small and dedicated community, we can't afford to decide by ourselves which is the "main" literature around a topic. If the Further reading was a conventional and common section in Wikipedia I would agree, but it seems to me it's not. --Aubrey (talk) 10:28, 26 January 2014 (UTC)
@Aubrey: We could add a note to WD:N or the talk page that only books or articles are allowed with this property that are used in the bibliography section of WP. This would minimize spam. --Kolja21 (talk) 05:54, 27 January 2014 (UTC)
On the other hand, Wikisource often have a "works about X" header in Author-namespace, so something like this is desired, no matter how Wikipedia is treating the matter. And then it does not matter how "main" the literature is or not. -- Lavallen (talk) 11:19, 26 January 2014 (UTC)
@Lavallen:, @Kolja21:: "works about X" is a good example, but it's kinda ambiguous. There are many books about X, sometimes, and not all of them should be staying in a "further reading" section. I generally like WD properties that are "facts", little pieces of information without POV issues. I agree that a simple metadata like "date of birth" or "nationality" is nnPOV sometimes, but they are often exceptions within a general rule. For example, in the Italian Wikisource we have 2 templates that are used when in a text an author/work is mentioned. See for example it:s:Storia_della_letteratura_italiana_(De_Sanctis)/I. I thus would like a "mentions" property for that, which could enumerate all the works and authors mentioned in a certain work. This is not "nnPOV", as it is the text which mentions them, and the community just puts manually the templates. This is the difference that makes me uncomfortable with the "Further reading" property proposal. Aubrey (talk) 10:19, 27 January 2014 (UTC)
I understand your worries, but intellectual work (looking at the content of a book) always involves the risk of POV issues. If you go to a library and ask for books about Oscar Wilde, you want an answer. If the librarian says: "I'm sorry, I have to be neutral but I can give you a a list of 50.000 books that mention this author", you can't work with this. --Kolja21 (talk) 15:41, 27 January 2014 (UTC)
In a first step stay with works which have an article in wikipedia or work used as reference in wikidata. This represents quite a large number of books. I think we have to fix some priorities. Snipre (talk) 13:04, 28 January 2014 (UTC)
This is understandable, but it remains unsatisfactory that, looking at the example Oscar Wilde (Q30875), an article of The Guardian (enWP, Citations 88) might be notable but main works about the author that are part of WP (listed under "References" and "Further reading") are ignored by WD. (See also: Book templates like de:Vorlage:BibISBN, used in 6 languages. Imho this bibliographic data should be transfered to WD.) --Kolja21 (talk) 14:49, 28 January 2014 (UTC)

Kolja21: Do we really need this? --Succu (talk) 20:05, 27 November 2015 (UTC)

(Example: en:Cèmuhî language#Bibliography.) statement is subject of (P805) is marked as "qualifier only". We use notable work (P800) although we have author (P50).

Hopefully this will bring more comments. --Kolja21 (talk) 21:25, 27 November 2015 (UTC)
Further reading, Kolja21? Something like de:George Engelmann/Schriften or de:Ernest Rutherford/Schriften? --Succu (talk) 21:43, 27 November 2015 (UTC)
No, for these lists we have notable work (P800) (deWP: Schriften / "Further reading" = Sekundärliteratur). --Kolja21 (talk) 22:00, 27 November 2015 (UTC)
  Question Is that valid? The documentation does not indicate that list items are acceptable values for notable work (P800). That sort of substitution strikes me as something that would complicate things. Dancter (talk) 22:30, 27 November 2015 (UTC)
Sure, Kolja21 … Both never published something… --Succu (talk) 22:37, 27 November 2015 (UTC)

  • Andy Mabbett There are a couple issue with this. data.nytimes.com is incomplete, and, as far as I can tell, unmaintained for some years. Second, the identifier it uses is not exposed in the article metadata unlike their Semantic Concept. I think its important to be able to use an identifier exposed in the html of the article, this would enable browser extensions to, say, notify the user of political donations by the entities discussed in the article. I don't object to having a separate property for the data.nytimes identifier, but I think there is value for having one for the Semantic Concept. Thinkcontext (talk) 16:18, 24 November 2015 (UTC)

  • Thryduulf It doesn't sound like anyone likes my original idea, though perhaps I didn't express it well. The alternate proposal to use the data.nytimes id, I think has problems, as I commented.  – The preceding unsigned comment was added by thinkcontext (talk • contribs).
    • I think the idea has merit, but your suggested implementation could be improved upon.

      • Thanks for the effort to move this forward. I'm fine with your suggestion of multiple properties if that would bring others on board. The NYTimes has done the hard work of associating these concepts with the Linked Data Cloud, I think it would be an easy way for Wikidata to add value by supporting it. Thinkcontext (talk) 21:56, 1 February 2016 (UTC)
        • I suggest five properties: four for concept names where concept types are known (type String for properties nytd_geo for locations, nytd_per for people, nytd_org for organizations, and nytd_des for descriptors), as well as type Number concept_uri for numeric URIs. Wikidata entities should have at most one of the concept names, and can also have a concept_uri. Since the Times has already done the work of associating nytd_geo/Kansas with Kansas (Q1558) via sameAs: http://en.wikipedia.org/wiki/Kansas, we can bot-import that data. Five properties also works well since there are five specific formatter/query URLs. Runner1928 (talk) 22:13, 1 February 2016 (UTC)

Sourceexternal reference
Motivation

I specifically need this property to capture the provenance on Protein items in Wikidata. Content is retrieved from Uniprot. Records in Uniprot are constantly being updated and with each new update a protein record gets a new version number. Currently, the version is stored using the property reference URL (P854) e.g. http://www.uniprot.org/uniprot/P04637.txt?version=237. We would like to be able to store a version of a source as a proper value, not being part of a URL. Although this example is highly domain specific, I believe a version to be applicable on other domains as well. I first thought edition to be a prime candidate to capture the sequence of a release, however, on second thoughts a version applies an updated item on the same concept, whereas edition suggests the same context but could differ on the context (e.g. A next edition of a newspaper, doesn't report an update on news reported in the previous edition Andrawaag (talk) 23:37, 8 January 2016 (UTC)

It may be interesting having that property, but how would we handle different phonological analysis? Moreover, Wikipedia does not have articles about phonemes, but articles about phones. I'm a bit skeptical about this property, but we should discuss it. --SynConlanger (talk) 19:59, 17 August 2015 (UTC)

statement disputed by (P1310)? Popcorndude (talk) 20:37, 17 August 2015 (UTC)
Mmmh, not sure. It may be one phoneme only that is disputed, or more than one, and different sources may dispute a different set. It can get quite complex. We could however rely on an arbitrary external phonological database and stick to that, like Phoible. Yeah, I think choosing one database should work. What do you think? Again, the problem remains that wikipedia does not have articles for phonemes and the same phoneme label could actually match different phonetic labels, so it wouldn't be safe, we need a proper work around I cannot think of... --SynConlanger (talk) 20:56, 17 August 2015 (UTC)
Oh yeah, also, there won't be a page for some phonemes because they are modifications of phones which are very unlike to be listed as items here or pages in Wikipedia. Like long vowels for example. I think we should concentrate first on standard phones, and then maybe move to phonemes. --SynConlanger (talk) 21:01, 17 August 2015 (UTC)
Perhaps this could be another use case of the "secondary articulation" discussed at Wikidata_talk:WikiProject_Linguistics#property_idea
e.g. "Language X":
  • "phonology contains" => "voiced dental fricative":
I have also corrected the above to phone and made consonant and vowel subclasses of phone rather than phoneme. Popcorndude (talk) 21:36, 17 August 2015 (UTC)
What if the language has two vowels that differ only in length? We would insert twice the same item as a value of this property and we would add a qualifier to the two values ("short" and "long" respectively)? --SynConlanger (talk) 21:59, 17 August 2015 (UTC)
I would say yes. Popcorndude (talk) 22:51, 17 August 2015 (UTC)
SynConlanger, Popcorndude I would say no. Instead have two item - a long version and a short version of the vowel - treat them as different phones/phonemes. Joe Filceolaire (talk) 10:22, 11 November 2015 (UTC)
  •   Support I'm not familiar with the linguistics but I can see that this property would allow us to make useful statements about languages and maybe about accented versions of those languages (in many cases we have separate items for these). Joe Filceolaire (talk) 23:52, 20 August 2015 (UTC)
We don't have separate items for IPA symbols with diacritics, I'm afraid you're mixing "letters" and "sounds" here. --SynConlanger (talk) 14:01, 21 August 2015 (UTC)
These would seem to fit the bill, am I missing something? Josh Baumgartner (talk) 23:15, 6 November 2015 (UTC)
I would be willing to use that instead. (Although using used by (P1535) may not be advisable, given the number of languages) Popcorndude (talk) 00:48, 7 November 2015 (UTC)
They would sort of fit the bill but I believe for specialised concepts and domains like this it is justified to have specialist properties instead of using these general properties. Joe Filceolaire (talk) 10:22, 11 November 2015 (UTC)

also, @Charles Matthews: Andrew Gray (talk) 12:30, 4 November 2015 (UTC)
So it is a bit of a mess. The means to resolve that is to work out which it is to be, or if both are acceptable then how they are differentiated. To me it makes sense to have a qualifier to describe the parent work of the article. We also need to consider how this can work, such as at the WSes, which have the articles and need to run quick/simple data pulls to the their wiki, not wanting to run high-powered queries.

So maybe it is needs a fuller exploration of what is looking to be achieved and whether we have the components in place rather than some of the simpler "I don't like it" responses.  — billinghurst sDrewth 03:12, 15 November 2015 (UTC)

The combination of described by source (P1343) with section, verse, paragraph, or clause (P958) can be used as a statement with qualifier and also within a reference claim. Specifying the overarching work (recte: specific edition of that work?) has huge merits as previous discussions emphasized, it`'s that work which allows accessing the quality of the reference. Infering this from information contained in a target item might be currently beyond the capabilities of most data consumers. However when we have specific items for entries in reference works they usually have additional statements which must be accessible, too. A minimal approach could consist of introducing a qualifier only property "reference item" to be used together with described by source (P1343) (in both situations). One probably will not be able to prohibit use of this item in contexts without overarching work of "dictionary" type, but IMHO use for journal articles or even individual blog entries seems to be appropriate. -- Gymel (talk) 11:44, 15 November 2015 (UTC)
You can specify this on the property definition page. Just as we do for most other online works. No need to repeat it on every P31:Q5. --- Jura 11:56, 15 November 2015 (UTC)
@billinghurst: This situation is appear due to Wikidata:WikiProject DNB#Examples : Subject of DNB entry recomends an improper use of P1343. I consider that this should be coverted to use with stated in (P248) as qualifiers. I can run my bot to fix it. -- Sergey kudryavtsev (talk) 08:31, 17 November 2015 (UTC)
@Sergey kudryavtsev, Gymel, Jura1: I am not sure what any of you are arguing in your later comments. I would suggest that would be resolved by examples of what would be right, and what is wrong. For P1343 which is right and which is wrong?  — billinghurst sDrewth 09:21, 17 November 2015 (UTC)
Supposedly the current use for P1343 is the outcome of a lengthy debate, thus I don't see a point of doing that change.
It's a non-issue if we use a separate property for DNB. --- Jura 09:32, 17 November 2015 (UTC)
I'm not principally opposing a dedicated property, but my proposal would be:
So P1343 gives only a gist from what's recorded in more detail in Q19019224 (questionable use of chapter (P792) there IMHO) and emphasizes the broader publishing context of the source. This is still a bit more indirect than in other cases without Wikidsource edition, where we appreciate a direct web link to the article via an additional qualifier . -- Gymel (talk) 10:36, 17 November 2015 (UTC)
@billinghurst: For P1343 which is right and which is wrong? — Usage rules of P1343 described in Property talk:P1343, of course. DNB is stored at enwikisource, so it should follow the second example in Property talk:P1343. I consider that the property usage rules have a highest priority over any project rules. Jura1 told some kind of "debates". But the property usage rules has scope whole Wikidata. There isn't even any notification at Property talk:P1343 about this consensus.
The motivation to use a qualfier. In the fact stated in (P248) as qualfier optimizes a retrieving information for a computer programs. If article item be a value of P1343, then a program code is obliged to inspect a claims in all item stored as P1343 values. But if a article item stored as a qualfier value for known values (such as Dictionary of National Biography, 1885–1900 (Q15987216), Brockhaus and Efron Encyclopedic Dictionary (Q602358) etc), then a program code may search only claims of P1343 with values needed to its purpose.
The logic P1343 with stated in (P248) and reference URL (P854) as qualfiers is already programmed in LUA-modules at least in ruwiki and ruwikisource. -- Sergey kudryavtsev (talk) 11:21, 17 November 2015 (UTC)
It doesn't currently work for DNB in ruwiki (with any approach), but a fix is available if a new property would be created. --- Jura 14:12, 18 November 2015 (UTC)

If it is notable that an item is capable of reading (Q199657) then I would think so. Josh Baumgartner (talk) 22:53, 13 November 2015 (UTC)
Yeah, but how would we determine if something is notable or not? Someone could add "ability > reading", "ability > speaking", "ability > walking" and so on to all person items ... what would we do about it? Revert those edits? Jonathan Groß (talk) 12:33, 17 November 2015 (UTC)
Fictional characters only, That's how you solve that problem. Also, perhaps make an item called something like "superhuman ability", then set up a constraint, and there you go. --AmaryllisGardener talk 19:33, 24 November 2015 (UTC)

Merge and use the existing items, per Pasleim. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 20:10, 13 November 2015 (UTC)

Two issues with the above comments

  1. Maybe it is more the time for those who have created the properties to assist in their redefinition. If one looks at the talk page for the proposed property to change it is very specific in the components that apply. For a general user to go and to modify this could be problematic, and such a change needs some level of imprimatur or governing and declared process. Someone clueless making that redefinition is simply going to be problematic.
  2. What is the cricketer bats right-handed, and plays tennis left-handed. It is quite well-known for even professional cricketers to bat one side, and bowl the other (eg. Michael Clarke) so without some delicate redesigning of the property, the simple statement of merge is a simple fail.  — billinghurst sDrewth 04:03, 15 November 2015 (UTC)

I am concerned about the name of this property. Different Wikipedia have different methods of choosing which matches do and don't go in the infobox, and I am take-my-car-if-I'm-wrong confident that we will not get a uniform consensus. Some Wikipedia go for the regular season of the league only, others for league + playoffs, others for league + playoffs + cups, and there are a couple of other deviations from these main categories. If we don't name this precisely enough, we will create a mess – English/German/French/Italian speaking editors would probably end up doing different things with the same parameter, and end users at individual wikis would have to painstakingly trawl through the values to work out which one is suitable for their wiki's purposes. I would suggest different properties for league and cup competitions, potentially one more for playoffs, plus one for total appearances. It may seem like overkill, but those three/four parameters would cover almost every conceivable use for this data. —WFC— 07:21, 3 May 2013 (UTC)

Bonsoir, excuse me but i'm best in french :) Le problème est que chaque wikipedia fonctionne différement, les francophones comptent championnat + coupes dans l'infobox, les anglophones seulement le championnat, le problème vient également des sources, des sites ont parfois des divergences notamment pour les joueurs du passé, même chose pour les clubs : la différence entre club professionnel et amateur est faite dans les infobox joueurs dans fr.wikipedia pas dans en.wikipedia, les équipes B ne sont également pas indiquées sur fr. wki (sauf pour les pays où le club B est une filiale, exemple l'Espagne)--Remy34 (talk) 19:21, 5 May 2013 (UTC)

  Oppose Why a property so specific ? In my opinion, it would be more appropriate to have a property "Total matches played" that could be used as a qualifier of the property member of sports team (P54) but also as a qualifier of a new property "takes part in" when the value is a sport competition. With this structure, the "Total league caps" property is no longer needed and the syntax is simplified. Same goes for the "Team goals for local leagues" and "Total leagues goals" properties : a "Total points scored" property should do the trick and could also be used for other sports than only hockey, football, handball and water-polo.

Motivation

As an inverse of family name identical to this given name (P1533) to make it easier navigation between both of them.

  •   Support for symmetry: if you like having it ;). To avoid having them mixed up or merged, P1533 is generally sufficient. --- Jura 13:18, 18 October 2015 (UTC)
  •   Oppose as creating inverse properties for their own sake bloats the database, makes items take longer to load and increases workload on contributors. Ideally, WD will eventually have support for true inverse properties which don't need to be individually entered and maintained, but instead automatically mirror to facilitate navigation within WD. I doubt that is coming any time soon, but creating a bunch of inverse properties just to facilitate navigation within WD is not a good plan. They are sometimes warranted, but in this case, I would have to say that family name identical to this given name (P1533) is sufficient. Note also that if there is both a family name and a given name that are the same, they should both be instances of a general name item that covers all applications of the name and this will give you a way to click-navigate from one to the other.

  • Sorted to person from unsorted. Josh Baumgartner (talk) 23:41, 6 November 2015 (UTC)
  •   Question Josh Baumgartner I think that I don't understand what you mean. Even if in the future the software mirrors the symmetric properties still two properties will be required to know which property has to be mirrored with each of them (or a way to have more than one name in each property and choose the correct one, or even a renaming of properties to "name-surname relation" to make sense in both of the elements). Also I don't understand how family name identical to this given name (P1533) can be sufficient if the one I know is the surname and I don't know if a name element exists. Also having one element that combines the names and surnames spelled in the same way as you suggest to make it easier the navigation wouldn't bloat the database more than creating one property for that? As far as I know an element and a property are both one row in the database, and while the same property can be used in more than one element a new element will be needed for each couple. -- Agabi10 (talk) 21:07, 7 November 2015 (UTC)
    • @Joshbaumgartner: Still waiting an answer to my question. -- Agabi10 (talk) 17:33, 15 November 2015 (UTC)
    • @Agabi10: Regardless of whether or not such a technical development ever happens, I oppose this property as unnecessary bloat. In fact, I don't even see a purpose for family name identical to this given name (P1533) in a structured database, much less a needless reflection of it. However, it is there and if the structure of given and family names being subsets of a general name item isn't handy for you and you have to put a direct link between the two, then family name identical to this given name (P1533) would do it. There is no need to have to enter that information on both family and given name items. I'm not sure I understand your question about knowing the surname but not the other, since even with your proposal, you would have to know both family and given name to be able to create the statement, and if you know both then why not use family name identical to this given name (P1533)? Josh Baumgartner (talk) 01:16, 18 November 2015 (UTC)
    • @Joshbaumgartner: I agree with you in the reasoning that this property and family name identical to this given name (P1533) would be completely useless, but only in a state of the database where there is no type constraint violations in where a surname was used as a value for the name property or in the other way. I know that the people who adds the properties to any of the name/surname elements (even if it is me or any other) will have to know, at least for a moment, that there is an element created for the other one to be able to put the property. The thing is that if after them someone tries to correct constraint violations related to elements with that property where the incorrect one is put they will find it easier.
      I also know that the ideal solution would be that the suggestion drop down shows first a value with a name instance for a name property, and the same happens with all of the other properties, which, as far as I know at this moment is not necessarily true. This would decrease the number of violations. Having correct names and descriptions for all the entities in all the languages would also help, but that's too idealistic. Being able to search for a value without having to use external tools (even if Magnus' tools are great) would also make it all of this easier to find elements with family name identical to this given name (P1533) with the current element as a value.
      As you can see I know that there are more ways to solve it that are also technically possible, but at this specific moment I think that an inverse property is the most feasible one. At least now I understand better why you are opposing and even if the explanation doesn't make you change your mind at least I hope that now both of us are understanding what the other wanted to make clear.  – The preceding unsigned comment was added by Agabi10 (talk • contribs).

name

   Done: name (P2561) (Talk and documentation)
Descriptionname the subject is known by
Representsname (Q82799)
Data typeMonolingual text
Examplesee below

We currently have several name properties which apply to certain specific types of names. However, sources do not always provide such definition when they provide a name, so there is no way to create a claim for the subject's name and know for sure which property to use. An educated guess constitutes a certain amount of original research. A contributor might see 'John Smith' and assume that given name (P735) John and family name (P734) Smith are appropriate, but even as uncontroversial as this may be to a native English speaker, there are many different linguistic constructs for names and many do not conform to first-last format. Even if we do add properties to cover all of the different classes of name out there, we will still have cases where the exact type is unknown, so we need a super-property that covers all of the name properties:

There are various ways in which this property can be used:

In an ideal world, all values would eventually be sorted into appropriate sub-categories as sources are found to substantiate such claims. The reality is that much of this type of specific detail is not available for some subjects and therefore the overarching property is needed. Josh Baumgartner (talk) 22:45, 20 October 2015 (UTC)

  • Why not just have a different property for each type of name, instead of the P794 (P794) business? There aren't even a dozen of them, I think. --Yair rand (talk) 23:11, 20 October 2015 (UTC)
    • @Yair rand: That is what I thought at first, but what do you do when you know it is their name (per your source), but it is not clear what class of name it falls under (because your source does not specify)? You are left to guess, which is not appropriate for a sourced statement. The other problem is that not all name classes have their own properties, and it is possible that the community will deem some of them too specific to warrant their own property. I actually would support a broad set of such properties, but there are cases where the right one does not exist. However, as I noted above, even if they all did, you still need this property to avoid invalid claims based on guessing. Josh Baumgartner (talk) 21:41, 21 October 2015 (UTC)
      • So, why the broad usage examples? I could support a property for situations where the name type just isn't known, but if you're specifying anyway, I don't see why this should be used. Also, the monolingual datatype is probably wrong. --Yair rand (talk) 22:02, 26 October 2015 (UTC)
        • @Yair rand: I'm not sure I understand your question, I am proposing that this be used in exactly that case: where the name type is not known (see the first example I show). As for monolingual datatype, I'm open as to how to do that better. Is a simple string a better plan? Josh Baumgartner (talk) 16:41, 28 October 2015 (UTC)
          @Joshbaumgartner: In the second example given above, you list "name <Leo Tolstoy>" along with the given name and family name properties. If the given name and family name are already specified, why the extra statement? Or am I reading the example incorrectly?
          Regarding datatype, the properties given name (P735) and family name (P734) both use the item datatype, which allows for more structured data (along with easier handling of multilingual issues, in my opinion). The "name" property would also need to be item datatype for other name properties to be subproperty of (P1647) of it, as suggested by Filceolaire below. --Yair rand (talk) 22:26, 28 October 2015 (UTC)
@Yair rand: Maybe the model of my second example won't prove to be how this is used, but even if that proves true, use for the first case is sufficient to warrant creation of this property. Also, details of how we apply subproperty of (P1647) is a discussion that does not necessarily relate to whether or not we should have the property. Making the datatype 'item' would be a huge burden to create an item for every permutation of a full name that might be cited. Josh Baumgartner (talk) 19:19, 18 November 2015 (UTC)
I don't think I understand the scope of the property. Are the examples above actual statements that would be added? If not, would the item Leo Tolstoy (Q7243) use this property at all? If so, what statements would there be? Could you give some more examples? --Yair rand (talk) 21:22, 2 December 2015 (UTC)

"family name" has datatype 'item' - it links to a surname item. The "married name" property proposed here is like birth name (P1477) in that the actual name is spelled out. This can still have family name (P734) as a qualifier. Joe Filceolaire (talk) 01:08, 9 December 2015 (UTC)
  • @Jura1: Well, sir, that's subject to negotiation, but I would suggest that the new property structure should parallel that of the existing "birth name" property, and be a complete name with the language specified. Married names often vary widely in structure, with the relatively simple taking of the husband's surname (e.g., Hillary Clinton), the creation of a compound name (e.g., Hillary Rodham-Clinton), the use of both husband surname and the wife's maiden surname as a middle name without hyphen (e.g., Hillary Rodham Clinton), a different feminine surname form in Russian and several other Slavic languages (e.g., Svetlana Andropovna), or Spanish married combined name forms (Hillary Rodham de Clinton). I'm sure there are numerous other cultural and linguistic variations with which I am unfamiliar, combined with what is often the complete choice of the parties in the relatively new scenario of same-sex marriages. I know that in several countries, such as Germany, the format of married names has been strictly regulated by law, while in most English-speaking countries, the only limitations are social customs, which have been evolving toward greater flexibility and variation since the 1960s.

Let's use Wikidata data model powerfulness ! author  TomT0m / talk page 17:46, 20 October 2015 (UTC)
@TomT0m: I appreciate your opinion, but it ignores the simple fact that for the overwhelming majority of our subjects with married names, we have neither an exact date nor even a year of their marriage. Of course, the situation is even more complicated for persons who have been married more than once. We need a property that identifies and collects all married names of a subject person within a single property, and that provides the flexibility to address the multiple married name formats not only in English-speaking countries, but multiple countries and cultures around the world. Stuffing married names into the "family name" property -- which only permits the entry of single-word linked family names -- does not do that. Please see my comment @Jura1 above regarding examples of the multiple formats of married names around the globe; the "family name" property simply is not made to purpose. Thanks. Dirtlawyer1 (talk) 19:08, 20 October 2015 (UTC)
@Dirtlawyer1: "the "family name" property simply is not made to purpose" => See the study about names on the talkpage of WikiProject Name for the different naming schemes in the world. This IS NOT a problem about married names, this is about all naming scheme. A scecialized property for married named won't help at all. I don't see how such a property will help if there is no known date either. It's exactly the same problem. It's enough to put the last known name with the "preferred" rank, and to use end date qualifiers and maybe qualifier about the order in sequence if we have no name. author  TomT0m / talk page 19:15, 20 October 2015 (UTC)
  •   Support The advantage of having "married name" as a simple string parallel to birth name (P1477) is that this is very easy to extract and use (and very easy to understand). Any scheme that involves qualifiers immediately is made a lot harder to query -- even more so if one would then have to filter out any other reasons why a name might have been changed. In contrast with two simple properties for birth-name and married-name, it becomes very easy to see whether one of those fields is missing.<br?>I am not against making sure that the married family-name is also reflected as a value for family name (P734) -- just as the relevant family-name part of a birth name (P1477) would be reflected in that way. Having an explicit property for the full married name as a string, parallel to birth name (P1477), in fact makes it easier to achieve and maintain appropriate values for the family name (P734) property, because it then becomes easy to check that values corresponding to both the birth name (P1477) string and the married-name string are present -- when these two properties are known and distinct, then there ought to be the correspondingly appropriate number of distinct values for family name (P734). Jheald (talk) 19:45, 20 October 2015 (UTC)
    • @Jheald: This argument has little to do with "married name" as such, it would hold for the name of the person as well. Plus ... it's a lot worse. A person can be married several time, how would this work ? We would have to create a "second married name" ? This would be a property mess. For this, rename "name at birth" "full name", and use ranks and date, per the same reasoning I used above. author  TomT0m / talk page 20:03, 20 October 2015 (UTC)
      • @TomT0m: If we were to go down that route, it would make it very difficult to systematically extract birth names for a particular group of people. Having to use comparison operators on qualifier dates for a variety of full name values would kill query performance stone dead.
        Yes, there will be cases where there will be more than one married name. But in such cases one will usually want to extract all of them, and one can use an ORDER BY clause. On the other hand, one may well want the original birth name in a separate column, and that would be a total nightmare with the system you suggest. Jheald (talk) 21:20, 20 October 2015 (UTC)
        • @Jheald: I'm pretty sure it's not harder to do a min or max in SPARQL than to do an order by clause.

        • PS: It is possible, see http://rdf.myexperiment.org/howtosparql?page=GROUP%20BY for example. author  TomT0m / talk page 21:30, 20 October 2015 (UTC)
          • The point is that you are then relying on all of the date qualifiers to be in place and to be correct, simply to extract the birth name -- it's a lot more robust simply to have a birth name property, then you don't have to rely on any qualifiers to identify the right value.
            Yes, you could introduce an additional sub-query for each individual, to join in all the names and all the date qualifiers into the query, with an ORDER BY and a LIMIT 1 to extract the earliest (if all of the qualifiers are there and correct) -- but it makes a hell of a lot more work; plus you would probably have to hand-optimise it, because the auto-optimiser is a bit random when it comes to queries involving sub-queries. (A sub-query is needed rather than GROUP BY because one can extract the earliest date with GROUP BY and MIN(), but there's no obvious way to get the name that goes with it).
            Finally, I don't think it is unrealistic for users to potentially want a list of individuals that included a column of birth-names and a separate column of married names. Particularly for a print-out, that is very often exactly the format one wants. (Something like this tinyurl.com/nwwk6ny, though at the moment we're a bit short of data). Jheald (talk) 22:07, 20 October 2015 (UTC)
  • A further thought: it may make most sense to introduce the "married name" property as a qualifier to spouse (P26). This would be the way to most directly associate the property with the right dates (if available) and the right spouse. Jheald (talk) 22:35, 20 October 2015 (UTC)
    • @Jheald: Good thought, but that only works if (a) we know at least the common, if not full name of the spouse, and (b) the spouse field may be entered as a plain text string (not linked text) for non-notable spouses. Dirtlawyer1 (talk) 18:38, 21 October 2015 (UTC)
    • Not sure how this would work for Molly Meacher (Q1943636) or Angela Merkel (Q567). --- Jura 13:03, 26 October 2015 (UTC)
      • @Jura1: I will let Jheald speak for himself, but I believe that Angela Merkel's legal married name is "Angela Dorothea Merkel," in keeping with the German name laws. When Merkel divorced her first husband she kept the Merkel name, and did not take her second husband's name when she remarried in 1998 (presumably because she was already well known publicly and politically as "Angela Merkel"). Had Merkel taken her second husband's name, as an example, the proposed property should be able to accommodate additional married names from second and third marriages, etc. Molly Meacher's legal married name is "Molly Christine Meacher," which appears to be relatively straightforward.

  •   Oppose per Yair rand. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 19:58, 23 October 2015 (UTC)
  • Strong   Support. Saying <family name:Clinton> with a start date doesn't tell us if her married name is Hilary Clinton or Hilary Rodham-Clinton or Hilary Clinton Rodham. We need this property with text datatype to specify the name she uses. 'Family name' can then be a qualifier to 'married name' to show what family names she uses since she is married with a different set of 'family names' as qualifier to her birth name. Joe Filceolaire (talk) 22:28, 25 October 2015 (UTC)
  •   Support, but it will need to be clarified that it is to be the full name, not just the assumed family name (or we can do it that way and make it 'item' datatype in line with 'family name'). Josh Baumgartner (talk) 01:22, 18 November 2015 (UTC)
    • Josh, it is intended that the datatype be text (not a linked item) and that the full married name be used, not just the assumed family name. Because of the various different types and forms of married names -- e.g., husband's family name, compound-hyphenated name, feminine version of husband's family name, maiden name as middle name + husband's family name, etc. -- the simplest and most accurate way to enter the name in every instance is text format. As it is, we do not have items for every surname. Dirtlawyer1 (talk) 14:05, 18 November 2015 (UTC)
    • Maybe "full married name" would be a better label to use to make it clearer. - Nikki (talk) 21:07, 19 February 2016 (UTC)
  •   Support, Some women can be married up to 10 times, think Bonnie Lee Bakley, and get a new name each time, or they may carry over the surname of the previous husband and hyphenate it with the new husband. --Richard Arthur Norton (1958- ) (talk) 18:44, 19 February 2016 (UTC)

Most of the information known about caves within Australia is held by numerous caving clubs/societies, with the ASF hosting a database (KID) which aims to collate the knowledge held by clubs into one shared source. The database contains a list of caves known within Australia, as well as detailed data on the characteristics of each cave (length, depth, features, date of discovery, etc). Caves usually have a little metal tag at the entrance stating the cave area code and serial number of the cave within the area. This unique identifier is referred to in literature published by speleological/caving societies, on maps and in books. Dhx1 (talk) 03:59, 22 November 2015 (UTC)
