has immediate cause

Done: has immediate cause (P1478) (Talk and documentation)

Description	granular factor that directly resulted in this outcome or effect. Used in conjunction with 'cause' (i.e. underlying cause), when the 'immediate cause' directly followed any values in 'cause'. Multiple values allowed.
Data type	Item
Template parameter	None
Domain	None. Often but not always events or processes. See examples and discussion.
Allowed values	Any. Often but not always events or processes. See examples and discussion.
Example	Cretaceous–Paleogene extinction event (Q55811) has immediate cause starvation (Q853930), impact winter (Q3032301)
Source	external references
Proposed by	Emw (talk)

Discussion

In talk about causes, things are often broken down into "underlying cause", "immediate cause" and "contributing factor". This proposal is part of a series to add those properties to Wikidata and help us structure data about causes. The goal is let Wikidata model causation in a way that balances expressiveness and simplicity. It emerges from discussion at Property_talk:P828#A_better_way_to_model_causation (permalink). See there for extended examples and discussion. If these properties are created, then fuller guidelines and documentation will be put together based on the linked discussion and any comments below. Emw (talk) 03:50, 11 September 2014 (UTC)

Danneks, Genewiki123, Infovarius, Micru, TomT0m, Filceolaire, Tobias1984, WS, Matthiassamwald, Danrok, John Vandenberg, others, there seems to be general agreement in Property_talk:P828#A_better_way_to_model_causation for a three-tiered approach to modelling causation. Cause is a complex subject but I think we can grow guidelines over time as we gain experience with structuring data about causation in different domains. Please comment and vote here on this property, and also on the 'has contributing factor' property proposal below. Assuming consensus is shown here on this three-tier framework, I'll plan to label of P828 from 'medical causes' to 'has cause' and update its description accordingly. Thanks, Emw (talk) 04:15, 11 September 2014 (UTC)

sourcing circumstances

Done: sourcing circumstances (P1480) (Talk and documentation)

Description	sourcing circumstances
Data type	Item
Template parameter	primary dates and places in infoboxes
Domain	qualifiers can be used for references and also for claims, if all specified references for claim would have the same qualifier
Allowed values	very limited set of values, precisely documented on property talk page, including: "approximate value" -- the source specified value and explicitly stated that value is approximate, but specify no precision information. For example, "born around 1709" or "died near Berlin". "possibly approximate value" -- the source specified not-ideally-precise value (like year instead of date of birth) and did not explicitly stated that value is approximate, but other sources explicitly did. "unspecified calendar" -- the source did not explicitly specify used calendar for dates between 1582-10-15 and 1918-01-26 (or, for example, for dates in context when Japanese calendar could be used), calendar model is assumed basing on source information and/or comparison with other sources "misprint" -- the information in source differs very little from other sources and suspect to have a typo "miscalculation" -- source provides both calculation sources, methodology (or link to it) and calculation result, but result is different from other sources and manual calculation basing on provided description
Example	"misprint" example Yevgeniy Yevstigneyev (Q1344765) → date of birth (P569) 1926-10-09 ( rank = normal ) ( stated in Krugosvet (Q2627728) ) 1936-10-09 + ( rank = deprecated ) (as qualifier), "sourcing circumstances" = "misprint" ( stated in Integrated Authority File (Q36578), "sourcing circumstances" = "misprint" ) "approximate value" example Al-Khwarizmi (Q9038) → date of birth (P569) 780 ( rank = normal ) (as qualifier) "sourcing circumstances" = "approximate value" ( stated in Biographical Encyclopedia of Astronomers (Q14525437), "sourcing circumstances" = "approximate value" ) ( stated in MacTutor History of Mathematics archive (Q547473), "sourcing circumstances" = "approximate value" ) ( stated in Integrated Authority File (Q36578), "sourcing circumstances" = "possibly approximate value" ) 783 ( rank = normal ) (as qualifier) "sourcing circumstances" = "approximate value" ( stated in Krugosvet (Q2627728), "sourcing circumstances" = "approximate value" )
Format and edit filter validation	—
Source	sources themselves, sometimes infoboxes for import ("born about 1234 year")
Robot and gadget jobs	some conditions shall be checked using bot: some values implies existence of other claims with sources and "deprecated" rank of the claim ("misprint", "miscalculation") some values implies existence of other references to the same claim ("possibly approximate value", "unspecified calendar" (if attached to reference)) "unspecified calendar" could be used only for time

Discussion

I've curated a list of a few thousand Stack Overflow tags and their corresponding Wikipedia articles. I asked on the project chat about how to incorporate it, and Emw suggested that this seems like the right place to store the information. I just built a list for StackOverflow.com, but I'm sure this can be done for any of the other sites.

I need a little clarification about creating such a property - is it acceptable to have multiple values of this property for the same entity? Because, for example, Apache HTTP Server (Q11354) should link to at least "apache" on StackOverflow.com, "apache-2.2" on ServerFault.com, and "apache-2.4" on ServerFault.com. Also, notice how some sites have separate tags for distinct versions of some software; would this be fine? Finally some Stack Exchange correspond to things that only have a sub-section of a Wikipedia article, and I'm not sure of the right way to refer to them on Wikidata.

Thanks for your input! Bskaggs (talk) 01:33, 12 September 2014 (UTC)

WikiProject Informatics has more than 50 participants and couldn't be pinged. Please post on the WikiProject's talk page instead. @Emw:

Support. This is a fantastic idea. Bskaggs, I recommend using pywikibot to enter this data; see Wikidata:Creating_a_bot#Pywikibot. You ask a few questions:

"is it acceptable to have multiple values of this property for the same entity?"

Yes, I think that would be acceptable, especially in the initial implementation. Ideally, in my opinion, we would separate each version of a piece of software into its own Wikidata item even if it does not have a Wikipedia article, but that's probably too ambitious to start with. So if Apache HTTP Server (Q11354) links "apache" on StackOverflow.com, "apache-2.2" on ServerFault.com, and "apache-2.4" on ServerFault.com, that's fine. We can refine things later.

"Also, notice how some sites have separate tags for distinct versions of some software; would this be fine?"

Yes.

"Finally some Stack Exchange correspond to things that only have a sub-section of a Wikipedia article, and I'm not sure of the right way to refer to them on Wikidata."

Please create an item for those things. You can do so programmatically. Wikidata:Bots has a lot of bots that do this kind of stuff and Wikidata:Bot_requests has notes on past work.

Support Tag creation on stackoverflow is done by experienced users, users can not tag their questions with less common tags and stackoverflow itself is under "cc by-sa 3.0" so this is supporting another free knowledge database, I don't see any reason to oppose and like the idea.

Are those club-specific player IDs which would only apply to a small group of rugby players? Not sure what the policy is for such rather special properties. --Bthfan (talk) 15:23, 21 July 2014 (UTC)

Oppose In my opinion, most of these properties are not needed. For Barbarians, All Blacks, French Barbarians, you can use the following syntax :

Richie McCaw (Q726148) member of sports team (P54) New Zealand national rugby union team (Q55801)

ranking (P1352) 1014.

What's more, neither the official british & irish lions' website nor the ERCrugby one do use proper identification numbers. I don't see the need to store numbers in wikidata then. I think it would be better to have one proposal for each type of ID. That way, we would be more able to sort out which property is needed and which is not. --Casper Tinan (talk) 20:12, 21 July 2014 (UTC)

Elo rating (P1087) changes every month, and it is a lot of work to keep the Wikipedias updated. This proposed FideID property for chess players, will make it easy to match chess players on FIDE's rating lists with their Wikidata items, so bots automatically can keep Wikidata (and indirectly Wikipedias using Wikidata) updated with the chess players' actual rating.

Casper Tinan Bthfan This isn't just for football. It's for every team sport which records such data. If there is a fan out there collecting these statistics and wants to donate them to someone who will make them freely available and provide the infrastructure for other fans to build on his work then I think that yes Wikidata could become a sports database, one which can be accessed by anyone for any analysis they want to do, without having to get a license to anyone - or it at least has the potential to do so some day.

Oppose we can have single language property per item, so that shall be used as default language for all language-related properties. I don't want bunch of properties like "lang+title", "lang+subtitle", "lang+edition title", etc. -- Vlsergey (talk) 16:42, 7 September 2014 (UTC)

Vlsergey: I am not really sure of what you have in mind. We already have "title", "subtitle" etc. properties. Depending on the type of item there should be either one value (the title in the original language, or several, like one title per language). Currently, we specify the language using qualifiers. But now, we can use the "monolingual-string" datatype. The only difference is that language will now be required (which seems to make sense), and stored in the mainsnak's datavalue rather than in the qualifiers (which is more convenient). --Zolo (talk) 07:18, 8 September 2014 (UTC)

@Zolo: for every FRBR edition item we have language of work or name (P407) property that specifies language for all language-dependent properties. I don't like the idea to specify same language value several times in the same entity -- it is big overcomplication and redundancy (for FRBR work we also have original language of film or TV show (P364)). Currently the language can be specified once per entity, and language-dependent values with different language (for example, French name for English book, by the way, it would be original research to define that) can be specified using qualifiers in very rare cases. That is enough. -- Vlsergey (talk) 20:46, 8 September 2014 (UTC)

@Vlsergey:, it is true that for items about a particular edition of a text, the language should be inferrable from the language of work or name (P407) of the item. However, in many cases (items about a book with translation, about a move, about an artwork). We need more than one title. In many cases, the label could do the job, but that is less precise and less powerful. For example, if the French title of a movie is different in Canada and in France, wich may happen, it is easier to use a statement (that can have qualifiers) rather than the label. Or if an artwork was given a title by an art historian, we should know in which language it is (for formatting reasons and others). It could be done analyzing the item given in the reference, but that may prove rather tricky. As a rule, I think it makes sense that when a string is in a particular language, this is indicated directly in the datavalue. This is really easier to work with than qualifiers. If the language is really easy to infer, adding it will not be much additional work. And if the language is not easy to infer, this is proof that adding it is useful.

@Zolo: each translation shall be separate item i.e. FRBR Edition with it's own language of work or name (P407) value, it's own title, editors, publisher, dates, ISBN codes, etc. -- Vlsergey (talk) 07:41, 10 September 2014 (UTC)

@Vlsergey: I know, but we also need items for the work, independently of the translation, and actually, this is the majority of our current items (en:War and Peace is not about an individual translation, nor is War and Peace (Q161531) only about the original edition). And for movies, we currently do not use separate items for each subtitled version. For visual artworks, it would just be meaningless (there is just one work, just different titles).--Zolo (talk) 08:28, 10 September 2014 (UTC)

Another argument against this property is titles in artificial languages. For example, what language shall we put for "Woblanadne Ctulhu Ftagn" title? It's obligatory, i.e. we won't be able just omit language, and not, it is not an English (it's only English transcription). We can't specify artificial language neither, because language list is fixed by server properties. -- Vlsergey (talk) 07:39, 10 September 2014 (UTC)

Proposed by	Micru (talk) 17:12, 8 July 2014 (UTC)

Discussion

Motivation. Sometimes it is needed to use a label as a qualifier of another property, or there is a label that only was valid during a certain period (to be used with qualifier "start/end date"). I also think that it could be used to model systems since inputs and outputs usually require a way of name the signals.--Micru (talk) 17:12, 8 July 2014 (UTC)

"Ширак, Жак" is a title of article in Lentapedia (Q17290934) (i.e. title of Q17317811 article) that describes Jacques Chirac (Q2105). So P357 (P357) could be used instead. This property both used as qualificator in Jacques Chirac (Q2105) for described by source (P1343) and as a property in Q17317811. I believe P357 (P357) is the best choice for own property of Q17317811 and using is as qualificator for described by source (P1343) was a natural choice. Well, technically i need this qualifier only until bugzilla:47930 is resolved, since after that i will be able to extract title of article from subitem directly. -- Vlsergey (talk) 03:07, 9 July 2014 (UTC)

Basic property.--Micru (talk) 13:55, 9 July 2014 (UTC)

Oppose. contained_in had been a property of the Basic Formal Ontology (BFO), but it's being removed from BFO 2 per the draft specification in favor of a more generalized location (P276) property. I think that's a move in the right direction; we can use located in to capture the meaning of contained in. Emw (talk) 03:56, 10 July 2014 (UTC)

@Emw: are you sure of that? Looking at "3.6.4 Location" it seems that it has been replaced by occupies_spatial_region which is similar to "contained in". The problem of "located in", also identified in BFO2, is that it needs some prepositional modifier to indicate the location relation between both entities. Instead of "contained in", we could think of a qualifier of "located in", maybe "spatial relation" with values "on", "inside", "above", etc.? --Micru (talk) 07:18, 10 July 2014 (UTC)

Discussion

Needed to express which function a given part has in a system (it might be different depending on the system). Notifying @Emw:--Micru (talk) 14:32, 9 July 2014 (UTC)

Comment: I would support this property if its semantics were the same as those of has_role from the Basic Formal Ontology (BFO). BFO underlies many of the most important ontologies in the Semantic Web, like Gene Ontology.

Simply put, roles are things that are optionally manifested in other things. Roles are realized in things by virtue of some special natural, social, or institutional set of circumstances. Roles depend on those things for their existence. For example, roles include any of our various occupations, or the articulated steering (Q499159) of a rudder (Q209760) from Micru's example. One would say that "E. coli has role pathogen", for example, because such bacteria do not have that role when outside an animal's gut. In contrast, one would not say "heart has role circulation", because hearts are typically found in bodies pumping one. (However one might say "heart has role dinner" when being eaten by a lion.) Another example is something like "hydrogen has role nutrient", as stated in the BFO ontology ChEBI, the reference ontology for chemicals of biological interest.

This brings me to how I would change the 'Description' value of this proposed property. It currently reads "the function an element fulfills in a given system". "Function", "element" and "system" all have significant meaning and would cause alignment problems with BFO ontologies as proposed.

"Function" in BFO is closely related to "role", but not the same. Functions manifest in something by virtue of its physical structure. "Function" differs from "role" in that the former always or almost always manifests in something by virtue of its physical structure, while the latter optionally manifests in something. For example, the means "heart has function circulation" would be preferred over "heart has role function", because hearts almost always circulate blood, and do so by virtue of their physical structure. Same with "hammer has function impact nails".

"Element" has strong associations with the set theory operator element of (ϵ). The distinction between an "element" and a "set" is what differentiates the basic membership properties instance of (P31) and subclass of (P279) -- these are often analogized to "element of" and "subset of". I would not want the proposed wording to imply that has role is only applicable for instances and not for classes. BFO permits usage of has role on both instances and classes and the proposed property should do the same.

Finally, "system" is a vague term and seems likely to produce undue confusion. Certainly Coco Chanel (Q45661) has a specific kind of role, the occupation fashion designer (Q3501317), and Escherichia coli (Q25419) has role pathogen (Q170065), but to say that either subject is "in a given system" is rather obtuse. Things that have a role can be part of a system, but that should not be necessary and so shouldn't be in the description. I think we can safely drop the word "system" from the description.

I would word the description as "something the subject does because of some special natural, social, or institutional set of circumstances", per BFO.

Micru, thanks for proposing this property. I think it's likely to become a significant positive outcome of the Wikidata:Requests_for_comment/Refining_"part_of" RFC. Emw (talk) 03:49, 10 July 2014 (UTC)

Description changed as per Emw's comment.--Micru (talk) 07:22, 10 July 2014 (UTC)

That sounds useful. But as the role/function distinction suggests, that may be tricky to work out. Something about which I was wondering: it would be interesting to have a property that would say the areas of intervention of a particular administrative unit (eduction, security, etc.) Would that be possible to say that with this property or would it pave the way to irredeemable messiness ? @Innocent bystander: --Zolo (talk) 09:04, 10 July 2014 (UTC)

@Zolo: "Has role" is for entities that change their function depending on the context. I do not think that an organization adopts different roles, it is created with a fixed set of "functions" in mind and it always fulfills those, for that reason I would recommend using has use (P366) or proposing a new "organization function" property if p366 seems too bound to artificial objects.--Micru (talk) 07:30, 11 July 2014 (UTC)

Perhaps this should have a different label, so that users don't accidentally select it when they mean to add character role (P453). --Yair rand (talk) 16:31, 10 July 2014 (UTC)

@Yair rand: I have been thinking about this, and I reached the conclusion that the confusion would be normal because... they are the same property. Well, character role (P453) is constrained to "interpretative roles", but there is the question if we can generalize character role (P453) for all uses, or if we can exclude "interpretative roles" from this generic one. Would a "Constraint:Item|NOT property=cast member (P161)" work?.--Micru (talk) 07:30, 11 July 2014 (UTC)
I'm afraid I don't see the similarities or associations between the two properties at all. --Yair rand (talk) 00:40, 15 August 2014 (UTC)

Support I think this property would be very useful in book cataloging, for qualifying the very various roles of the authors : editor, translator, preface, etc.,

and yes Micru, organizations can have different roles in the same action, depending on many things, time, money, politics, etc. : an organisation can also be authoring a book... as author, as editor, as publisher... and it may also (for administrations), lead a politic, finance it, coordinate, etc. --Hsarrazin (talk) 15:33, 14 August 2014 (UTC)

Done as P1452 (P1452). Similar to character role (P453), but p453 is constrained to people, while this new property can be used for everything. Notification: @Hsarrazin, Yair rand, Innocent bystander, Zolo, Emw:--Micru (talk) 14:47, 20 August 2014 (UTC)

Oppose. I support the spirit of this property -- capturing cardinality constraints -- but I think we should use a generic cardinality property and merge quantity (P1114) and this proposed property into it. (As a practical matter I would redefine P1114 to have the semantics of that generic property.) That's much closer to how OWL and existing major ontologies handle cardinality constraints. "Cardinality" might be too stuffy as a label for such a property -- perhaps we could get by with 'number' or 'has number', and supply a description that indicates it doesn't take phone numbers?

I agree something needs to be done but we need a solution that works for people with multiple names. I need to think about this. Filceolaire (talk) 22:28, 17 July 2014 (UTC)

@Filceolaire: Yes, actually you are right, we'd need a generic transliteration (monolingual string) with this property as qualifier (description changed accordingly). It would be easier to have the name as an independent item, because then we'd be able to put all transliterations for that name together, but that again seems to be in the domain of linguistic data... --Micru (talk) 06:56, 18 July 2014 (UTC)

Consider Joseph Stalin (Q855).

birth name:იოსებ ბესარიონის ძე ჯუღაშვილი (in Georgian)
- Transliteration:Ioseb Besarionis dze Jughashvili (English)
- Transliteration:Iósif Vissariónovich Dzhugashvili (spanish)
Known as:Ио́сиф Виссарио́нович Ста́лин
- Transliteration:Iosif Vissarionovich Stalin (English)
Known as:Ио́сиф Ста́лин (Russian)
- Transliteration:Joseph Stalin (English)
- Transliteration:José Stalin (Spanish)
- Transliteration:Josef Stalin (Spanish)

Qualifiers can't have qualifiers so I'm not sure where to put the 'transliteration type' property.

it does look like we need a 'known as' property and a 'transliteration' (or maybe 'localisation') property. Filceolaire (talk) 11:50, 18 July 2014 (UTC)

@Filceolaire: I don't think that we can do that with qualifiers, because also transliterations may have sources. I have tried to replicate with items your structure here: https://test.wikidata.org/wiki/Q558.--Micru (talk) 12:47, 18 July 2014 (UTC)

Still thinking about this. So basically we have 2 solutions:

Each time we want to describe a name, we create a separate item. Which means that if we want to get the Arabic transliteration of Richard Wagner we do it through Richard (Q1249148) and Wagner (Q2539239). There are 2 issues first that it may seem unwieldy and requires creating items even for nicknames and given names that were given to only one person. More importantly, it may not always give a correct result. One case in point is transforming transmogrigying a name into Chinese (not sure it would be called transliteration, but it is needed notheless). For instance, Richard appears to be rendered the differently in Chinese in Richard Wagner and in Richard the Lionheart.
Using qualifiers. That seems to require create new properties, like, I guess a string-type "first name" property in addition to the current item-type one. It would also create massive redundancy (repeating the 10s of transliteration of the same first name in 1000s of items). And as Micru notes that may also have issues for sourcing (which actually is an issues I have encountered several times with statements containing qualifiers, so there may be something more general at stake here).

We could also make a mix of the two, but that may not be very intuitive.

We could also decide that we can let the software do the job for simple cases (providing standard transliterations of Greek or Russian words for English-speaking users iappears to be pretty mechanical and straightforward). But it would not work for all cases, so that would not really solve anything. -Zolo (talk) 13:24, 18 July 2014 (UTC)n

@Zolo: you forgot to mention the third option, which is to treat the whole name as an item, and then transcribe/adapt it as a whole, linking to linguistic data when/if available with qualifiers (see linked items).

I think we should not enforce any solution, just offer a path for the names of an item to grow organically depending on the number of editors interested in the item: first only labels (as now), then use monolingual properties for transliterations all in the same item, and when the item grows too big, then split it into subitems (see my example).--Micru (talk) 13:37, 18 July 2014 (UTC)

When we get a 'monolingualtext' datatype I look forward to getting the 'official name' property and will be proposing a number of other name properties. Also proposing that the datatype for the 'birth name' be changed from 'string'.

When we get a multilingual text' datatype I will be proposing a 'localised version' property with multilingual text datatype, to use as a qualifier for the name properties. For some languages there may well be more than one commonly used localisation for famous names (e.g. for languages using more than one script). For many small languages the wikidata transliteration will effectively become the default name for that person/country/company since no one else has ever bothered to write about that item in that language before.

Note that there is still no place to put a 'transliteration type' property but we do get a 'language' qualifier for free for each 'localised version'. Filceolaire (talk) 19:29, 18 July 2014 (UTC)

The items would fulfill the notability criteria because they are linked to this property.

I don't see how Wiktionary support would be of any help, as it's structured by string sequence rather than meaning. @Micru: Maybe you could explain how this would work. --- Jura 08:12, 22 June 2014 (UTC)

With lexical data support we would link to the item containing all declinations and lexical forms. I strongly discourage this property. Instead I recommend of the following:

facet of (P1269) for existing items like American (Q4742863), understanding that these items are not meant to represent the word, but the concept of being of a certain place and how that concept came into existence.
a mono/multilingual string property for demonyms with appropriate qualifiers

--Micru (talk) 20:24, 23 June 2014 (UTC)

Wiktionary doesn't seem to be on the planning horizon, so we need to find another solution.

Obviously, we do need to be rigorous with the labels, otherwise automated use of the words isn't possible. Current infoboxes in Wikipedia just use one form, so it shouldn't be much of an issue to define a primary form for this either.

Some sort of a string property could work. If the above solution seems to complicated, we could just start with the existing string format and add qualifiers to define the language used. --- Jura 05:29, 29 June 2014 (UTC)

Jura, that seems more reasonable and the monolingual datatype is almost ready (no need to qualify with language). If there are articles about the demonym, they can be linked with the qualifier statement is subject of (P805). With the datatype change I would support the proposal.--Micru (talk) 08:53, 29 June 2014 (UTC)

In the far future, a "phone number" datatype would be great, since Wikivoyage often gets invalid phone numbers: many people insert a homepage URL instead, even though we have a separate field for the homepage URL (and these URLs are valid IRIs, so just IRI would not catch the mistake).

Support IsIn and IsPartOf are identical in a technical sense. Maybe the naming IsIn is better because this feature can be used not only in the main namespace. This information has to be specific to each language branch. Maybe it is useful to distinguish between one primary and obligatory IsIn and a random number of secondary IsIns. For instance Garmisch-Partenkirchen is primarily in Bavaria and secondarily in the Alps. The Alps are in Europe, and it is not possible to put it in a single bread-crumb trail with Bavaria or Germany. --RolandUnger (talk) 13:10, 2 February 2014 (UTC)

Proposed by	Emw (talk) 03:53, 15 September 2014 (UTC)

Discussion

This would be an inverse property of has cause (P828). To make that apparent, the label would follow the 'has X' and 'X of' pattern used in properties like has part(s) (P527) and part of (P361). It would have the aliases 'has effect', 'has result', 'outcome of', and others.

Like other inverse properties, this property, 'immediate cause of' and 'contributing factor of' would require editors to use common sense. For example, this means not putting 15 million 'cause of' claims in Big Bang theory (Q323) or physics (Q413). When not used in clearly inappropriate ways this generic property to capture causally downstream information would be quite useful. Emw (talk) 03:53, 15 September 2014 (UTC)

~~Withdrawing proposal~~. Sorry, it just occurred to me that for consistency in how P828 was relabeled from 'medical causes' to 'has cause' to facilitate a broader approach to modeling causes, so P780 would make sense to relabel from 'symptoms' to 'cause of'. That would make this property proposal redundant. Please see Property_talk:P780#symptoms_-.3E_cause_of. Emw (talk) 14:14, 21 September 2014 (UTC)

The main inspiration for this qualifier proposal is including an explanation of why a marriage ended (e.g., divorce (Q93190), annulment (Q701040)), something often kept track of in infoboxes but not included in Wikidata so far. We can definitely broaden it to include any more information about why something started or ended though, such as if someone transferred schools, dropped-out, etc. Cbrown1023 talk 02:30, 6 August 2014 (UTC)

If this is to be used for many properties, I don't think that "reason" is the right word here. --Yair rand (talk) 22:31, 6 August 2014 (UTC)

What do you suggest? I couldn't come up with a better name either, but "end reason" is the best one we came up with. If we agree it's a good idea, though, the good thing about Wikidata being a wiki is that we can always change the name or add new aliases. Cbrown1023 talk 01:32, 7 August 2014 (UTC)

Comment: Cbrown1023, great idea. I would support this property if it had the label 'end cause'.

Oppose. This is Wiktionary's domain. This should wait until we have a system for dealing with complex (very complex) linguistic data. --Yair rand (talk) 02:16, 8 September 2014 (UTC)
- Wikipedia generally includes this information (see infobox samples above). --- Jura 06:08, 11 September 2014 (UTC)
  - I am aware of that. Still, this data is well beyond what Wikidata is currently capable of. Demonyms are words, and words are complicated. Some languages can have hundreds of different forms for a demonym, and there are thousands of languages we can cover, and these are interlinked in strange ways. Simple monolingualtext won't work well at all. --Yair rand (talk) 23:38, 15 September 2014 (UTC)
Comment I came here to propose this myself. It's relevant to us in addition to Wiktionary, as evidenced by the fact that it's used in infoboxes (for example, see w:en:Halifax, Nova Scotia and its unusual demonym "Haligonian"). But Fralambert does make a good point that it would have to be multilingual, so now I'm torn. --Arctic.gnome (talk) 15:55, 12 September 2014 (UTC)
- Good question indeed. For many places demonyms might only exists in one or two local languages. This property can easily hold entries for several languages. A solution that requires translation of the label in every conceivable language might not be that practical. This was the disadvantage of the earlier "item" property. A multilingual property is likely to have the same drawback. --- Jura 08:41, 13 September 2014 (UTC)
  - I guess most places (other than countries and world-cities) will only have a commonly-used demonym in the local language. Where demonyms exist in two or three local languages, we could add both of them with the language as a qualifier, like I did with legal citation of this text (P1031) on Supreme Court Act (Q7644846). However, countries and world-cities have demonyms in every language, so maybe we should change the name of this parameter to "local demonym"; either that or we wait until compatibility with Wiktionary so we can link to their list of all demoyms. --Arctic.gnome (talk) 20:17, 13 September 2014 (UTC)

Necessary property for modeling w:FRBR levels. Not necessary all the time, but in some cases it might be useful to model the manifestation separately from the expression. --Micru (talk) 08:23, 19 August 2014 (UTC)

Could you show at least one such case, please (for works)? Danneks (talk) 18:17, 19 August 2014 (UTC)

@Danneks: There are no items like that at the moment, because it is for special cases, but I created one for this example:

work item: Iliad (Q8275), all Iliad versions
- edition item: Iliad (Q17559055), a Catalan translation by Conrad Roure
  - manifestation item 1: Qxxx, the original manuscript by Conrad Roure kept at the library
  - manifestation item 2: Qxxx, a print run of 300 exemplars with 300 pages
  - manifestation item 3: Iliad (Q17559097), special print run of 30 exemplars with 336 pages
    - item: c:File:Iliada (1879).djvu: a scan of one of the 30 exemplars, contains author signature on page 2

This is of course hypothetic, normally it would be enough having only the work and edition item, only when more than one manifestation is added, then it would be needed to split it.--Micru (talk) 19:41, 19 August 2014 (UTC)

@Micru: Thanks. I'm not sure that we need distinct items for different manifestations of the same edition, we are not a library after all :) Alternatively, we can create "text" property with links to Wikisource, like image (P18) and document file on Wikimedia Commons (P996). And I think that text can be translated unambiguously into many more languages than manifestation of. Danneks (talk) 09:32, 20 August 2014 (UTC)

@Danneks: Yes, that could be another option, but if it is just to link with the "Wikisource index page" (the text is a sitelink) I wouldn't call it "text", but perhaps simply "Wikisource index page" which is what it is :) I'm also thinking that such a property could be used as qualifier of "scan file".--Micru (talk) 11:15, 21 August 2014 (UTC)

And what about non-bibliographic items? How do we link classes like banknote (Q47433) => money (Q1368)? Do we need a more user-friendly name, like "representation of"? Or can we perhaps (ab)use "instance of"? Pinging @TomT0m: to see if he has some idea.--Micru (talk) 11:15, 21 August 2014 (UTC)

Well, money is defined as any object generally accepted as payment, and banknotes are clearly a subclass of such objects. Danneks (talk) 11:47, 21 August 2014 (UTC)

There are two "money" concepts, one is "object accepted as payment", and the other "record accepted as payment", I guess you are referring to the first one which is clear, but I am more interested in the second. Or better said, how to connect both concepts in a better way than having both merged in one item.--Micru (talk) 12:25, 21 August 2014 (UTC)

Sorry, but I don't understand you at all. Isn't record an object (Q488383)? Or maybe you can give reference to the fact that there are two money concepts... Danneks (talk) 12:46, 21 August 2014 (UTC)

See the lead text of enwp: the main functions of money are distinguished as: a medium of exchange; a unit of account; a store of value; and, occasionally in the past, a standard of deferred payment. Any item or verifiable record that fulfills these functions can be considered money. By "item" it is meant a physical entity, and by "record" it is meant an information entity.

Information is what happens when you perceive something, and a physical entity happens independently of perception. To put it briefly, "a banknote" is always happening, but the "realization that the banknote is worth 10EUR" only happens when someone perceives it and decodes its message.

object (Q488383) has the connotation of something perceived by an observer, not of something happening independently of perception.--Micru (talk) 13:09, 21 August 2014 (UTC)

Well, it seems that for different philosophers, "object" has different connotations... Personally, I like the opinion "object=entity". So I think that "banknote" does not exist unless someone will say that it is a banknote, and its "atoms" do not exist unless someone will say that they are atoms... We can say that they "correspond to matter", but the problem is that we can't say anything about matter itself... And I can say that "money" correspond to some matter too, I have some material money :). So I think that having the "instance of" property would be enough for all purposes, unless you will show a convincing counter-example. Danneks (talk) 15:12, 21 August 2014 (UTC)

@Micru: This property seems a little bit abstract to be OK with only one example to me. I'm not sure I understand this property. For the money problem, I would say it's easier to say that each coin is an object with a facial value, the facial value would be a number with a currency type. It seems easier to model, a property facial value, a qualifier property for the currency (or converse). For editions, how is this different from using instance of (P31) ? TomT0m ^(talk) 16:40, 21 August 2014 (UTC)

@TomT0m: Well if you are fine using instance of to link class-to-class, then I'm fine with <banknote (Q47433)> instance of <money (Q1368)>. Another example could be <human> instance of <person>, or <teacher> instance of <profession>.--Micru (talk) 09:54, 22 August 2014 (UTC)

@Micru: You're one of the ones who like controversies, aren't you ? :) You can't do that without reflexion. Both human and persons are class of real world objects. This means if you take the set of all persons and the set of all humans, the set of all humans is a subset of all persons. This means subclass of (P279) must be used. Now if you take a concept like clade, this is different. The set of all clade is not a set of real world objects, like the set of all humans. Actually <human> is an example of a clade. So the set of all clades is a set of sets of organisms, I will call this kind of class a metaclass. Classes can be members of metaclasses, but not subsets of metaclasses. We should think "member of the set of = instance of (P31)" and "subset of = subclass of (P279). When I talk of artwork, I use a little trick allowed in the OWL language: I use the same item for a written work and for the sets of his, if I understand well, the sets of its printed embodiment. We can do that if we can always tell if we are talking of the item as an artwork or if we are talking of the item as a set of books. This seems cool to me as we do not have to introduce a new concet like embodiment If we are linking an instance of a book object to an artwork item, we can know for sure it is as a class opf books. Now I don't know how that relates to money :) Maybe a property who links abstract things to cncrete one is cool. Can we say a material measure (Q1329540)  

is an embodiment of its measure unit ? this would be cool but can't cover the new abstract definitions of the International system for example. TomT0m ^(talk) 10:33, 22 August 2014 (UTC)

@Micru: A set can be an element of another set... a type can be a term in a universe type, which in turn can be a term in another universe type... a category (Q719395) can be an object of another category... This is not controversial, compared to "real objects" and "manifestations". Danneks (talk) 11:57, 22 August 2014 (UTC)

@TomT0m: Neither I like controversies nor I dislike them, they just happen :) The example of "person" is complex, because there are different views [6], but if you say that <human> instance of <clade> to mean "member of the set of", that is fine for me.

A <standard (class)> is definitely a manifestation of <measure unit (class)>. If you think the words "manifestation", or "embodiment" are too abstract, "execution", "rendering", or "interpretation" are also similar. OTOH, if we can use "instance of" for that purpose, I am also fine with it.--Micru (talk) 12:23, 22 August 2014 (UTC)

Maybe "used to define" would be more accurate? There is the definition of metre (Q11573), and this definition mentiones light — quite a definite relationship. Danneks (talk) 14:44, 22 August 2014 (UTC)

@Danneks: <definition of metre (1983)> manifestation of <metre>. A metre is just a concept, and it has been materialized in different ways through the years.--Micru (talk) 15:44, 22 August 2014 (UTC)

@Micru: And here I'd have used instance of. "metre (1983)" is also a concept: I suspect that only humans know about metres, it requires a lot of abstraction. Danneks (talk) 15:58, 22 August 2014 (UTC)

@Danneks: Exactly, both of them are mind-made, but as you were saying "metre (1983)" mentions light, which puts it closer to physical world than the other one. I'm also fine using <instance of>, but one has to bear in mind that "metre (1983)" is a class.--Micru (talk) 16:03, 22 August 2014 (UTC)

Don't follow you guys. This discussion seems to go way out of control. If meter is a class, then which definition would you give for its instances ? the metre class is the set of all objects of precisely one meter ? Do not seem very useful. TomT0m ^(talk) 16:15, 22 August 2014 (UTC)

Well, we can say: "this distance is a meter". Danneks (talk) 16:34, 22 August 2014 (UTC) I mean, the distance between given two points. Of course, we can say this about many pairs of points... whether it is useful or not. Danneks (talk) 16:51, 22 August 2014 (UTC)

I see it as this:

<metre> concept gestated from 1668 to 1771 and that is still alive
<metre (1983)> one of many implementations of the concept
<metre (physical measure)> element built or measured following the 1983 guidelines

Depending on how many of those abstraction levels you represent in Wikidata, some statements make more sense than others. For instance if we represent all 3 of them, to say "<metre (physical object)> instance of <metre (concept)>" conveys less meaning than to say "<metre (physical object)> instance of <metre (1983)>". It is important to realize that there are no "fix" classes. Like the lense of a microscope we can adjust the abstraction level of any class to at least those three levels. Perhaps it would be more clear if we use a distinct property.--Micru (talk) 17:03, 22 August 2014 (UTC)

Fortunately, we would never have an item <metre (physical measure)>, because now it is impossible to build that physical element. And without its building, it will remain an abstract concept, the same as <metre (1983)>. Danneks (talk) 17:20, 22 August 2014 (UTC)

Technically speaking, every time that you measure something you are instantiating a class based on <metre (1983)>. And with Commons joining in, maybe someone wants to create an item to represent the object that this image depicts. So never say never :) --Micru (talk) 17:31, 22 August 2014 (UTC)

This image depicts a metre bar, which is not an instance of a metre, but of a metallic bar. All we can say is that a certain definition of metre uses that bar... maybe sometime we will be able to say in which way the definition uses it, and it would not involve any "manifestations", only the procedures which were used to compare measuring instruments with that bar. Danneks (talk) 18:04, 22 August 2014 (UTC)

This image depicts a metre bar according to your mind, and which is not an instance of a metre according to your mind :) Without the mind there cannot be known if there is or there is not, because the mind precedes all that can be known. Without it you wouldn't be able to codify things and much less think about if there such a thing or not. It is impossible to get rid of "manifestations" (transformation of concepts into physical matter/processes) because it is impossible to get rid of the mind without getting rid of the idea that there are things. You can hide that as much as you wish, or pretend that it is not like that, but as soon you scratch a little bit this fact reappears, which in fact it is just a co-lateral effect of having a smaller system codifying a larger container system and building a model out of it.--Micru (talk) 07:25, 23 August 2014 (UTC)

Yes, and Wikidata is a database of human knowledge. Danneks (talk) 07:58, 23 August 2014 (UTC)

BTW, I don't think that to get rid of the mind is a healthy desire :) It's like "no man, no problem". Danneks (talk) 08:13, 23 August 2014 (UTC)

So that's why there will always be concepts that can happen only in the mind (like mathematics), concepts that happen in the mind inferred from contact with reality, and things that happen independently from the mind but that we wouldn't know if we didn't have a mind to interpret them. For me all this conversation was about defining the relationship between the 1st and the 2nd group, if it is not clear I think it is better to let this discussion aside for a while. Oh, yes I agree about your last point... better than the desire for no-mind is the wish for understanding and control over it. Perhaps a good motto for the site would be "Wikidata - the mind you can edit" :) --Micru (talk) 09:35, 23 August 2014 (UTC)

Of course I understand that you want to distinguish the concepts of the first and the second kind, the only problem is that they could not be clearly distinguished. Yesterday aether was "real", today it is "abstract"... Wikidata is needed as a reliable source of knowledge, not as a source of philosophical guesses of its editors. Danneks (talk) 10:14, 23 August 2014 (UTC)

"Wikidata is needed as a reliable source of ~~knowledge~~ guesses", FTFY :) As expressed in this essay, abstraction is not a boolean parameter, but a continuum. If we wanted we could put thousands of shades and they will never end, but there are some basic categories that are useful for organizing knowledge and for making sense of it.--Micru (talk) 11:14, 23 August 2014 (UTC)

OK, if you are sure that this way of making sense does not generate controversy in a multi-cultural setting and we would not get statements like <Muhammad> <manifestation of> <Allāh> all over the place, then I don't object. Danneks (talk) 12:01, 23 August 2014 (UTC)

Wikidata has sources to deal with controversial statemants, that actually reads [claim] according to [the source]. We also have qualifiers like disputed by. But I really would recommand not to use this property out of libraries scope. TomT0m ^(talk) 12:11, 23 August 2014 (UTC)

@Micru: FBBR seems to be an accepted model, can you provide an actual usecase of it ? And out of curiosity, why did you extract only one relationship of it when they forms a whole (meter seems clearly out of scope anyway). TomT0m ^(talk) 10:28, 23 August 2014 (UTC)

@TomT0m:My main interest is to keep compatibility with the Library of Congress, The British Library, and other national libraries like DNB that are implementing RDA (the manifestation of FRBR). What others confuse with "philosophical guesses", is in fact a well-established conceptual framework with wide support. By making sense of that framework in our structure and having the necessary properties to model it, then it will be possible to keep interoperability with huge bodies of data. The use case is to automate metadata import and maintenance as much as possible with as many standards and sources as possible. I did extract only one relationship because it is the most significant one that we are missing (see here). Bear in mind that we are taking some liberties in its application, in order to keep it simple at the begining of item creation, but allowing an expansion of the structure whenever needed.--Micru (talk) 11:14, 23 August 2014 (UTC)

It seems contradictory to both take liberties to maintain compatibility. When it is up to mass import, what about database laws issues ? It's probably OK for the US database imports, but … last to maintain compatibility with a well defined goal, how about some documentation about the mapping ? All 1/1 properties, with the same intended meaning ?

Comment on your spreadsheet : I don't get the 3rd and fourth column. Isn't item/manifestation relation a 1/1 mapping ? TomT0m ^(talk) 11:38, 23 August 2014 (UTC)

Item compatibility can be achieved by keeping a clean concept tree and by knowing the abstraction level that an item represents (think of abstraction level as a zoom). External properties can be mapped directly to q-items and inferred which is the closest property we have. And more documentation would be nice, but it requires a lot of time that I don't have. Item and manifestation are different, I gave an example high above this thread, but abstraction levels are approximations, and as such you can collapse them or expand them at will.--Micru (talk) 12:15, 23 August 2014 (UTC)

Sorry, if you can't be clearer than that I won't follow this. TomT0m ^(talk) 12:35, 23 August 2014 (UTC)

@TomT0m: If an item is an instance of any of these items, the instantiated item represents a work. If the item has "edition of" we know that it represents a expression of that work, and if another one is an instance of any of these then it represents a manifestation. FRBR-items are not relevant because they will be stored in Commons and linked with an specific property. In the excel file you have the properties required to connect the different abstraction levels (if they exist). Is that clear enough?--Micru (talk) 13:13, 23 August 2014 (UTC)

@Micru: seems OK to me at first sight. If I understand well, a lot of their conceps implicitely maps with our concept. And if we choose to use instance of to link for example to link a work to a radiophonic manifestaion of this work or edition, thought as classes of manifestations, we can also map this to their manifestation of concept. In this view an edition can even be thought as a subclass of a work I guess.

OK, just to recap :

An artist starts to worw on something. He gets a sequence of intermediary results. This is what we could «work». finally he gets something he wants show other people, this is what we could call « an expression ». An expression is a text, or a sound, or a video. If we read and record the reading of a text, we get another expression of a work. An expression could be seen as a step in the working sequence of the author(s). For that matter, he uses a communication medium like a book or a radio station. He or they can produce any number of those manifestations. This mean that a work by itself in this model is neither textual or vocal by essence. A manifestation is the set of concrete objects storing the same expression. Different supports can store the same expression (CD - casettes), then they refers to the same expression, but belongs to manifestations. Expressions are sets of identical physical objects. A manifestation as a class can be seen as the set of the union all the physical objects of manifestations of the same expression.

I think there could be a mismatch here. I woud identify an edition in the Wikidata sence with a manifestation, not to an expression. A reprinting of a book with the same text but with different colors is an edition. TomT0m ^(talk) 15:30, 23 August 2014 (UTC)

@TomT0m: On a more practical level it is not as clear-cut as that, but rather:

I want to model a novel, and I create an item (Qx) to enter some data about it. This item might represent any abstraction level or all at once (down to physical item), depending on how much data I entered. Then someone else sees my item and creates a new item (Qy) for a translation in his/her language and moves some of the data from Qx to Qz which is a new item more specific for part of the data I originally entered. Qx, my original item, now has a more limited scope, it has stopped representing all levels, and now it only represents work. Qy and Qz are now representing the remaining levels. Then a third person comes an adds some sub-items to Qz, which stops representing expression-manifestation-item, and now represents only expression...

As you can see the items don't have a fix "area of influence", it keeps evolving depending on how much data is fed to them. The apparent mismatch is not only intentionate, but inevitable if we want to keep some flexibility. In practice it is much easier because people in general understand that if there is this much data, the item refers to this, or that if this is an instance of something material, then the item must be material. The only missing link was when we have to connect a class of non-material objects with a class of material objects. If you say that using "instance of" is enough, then it's fine.--Micru (talk) 17:32, 23 August 2014 (UTC)

I think the best use case of this is for instances, not classes. The problem I find with classes is the many-to-many problem, so to me it's not clear if we were using it for classes what direction to go in, i.e.

Reversed property, manifested as

Encylopedia (work) manifested as collection of books (manifestation)
Encylopedia (work) manifested as website (manifestation)
Encyclopedia volume (work) manifested as book (manifestation)
Encyclopedia article (work) manifested as book section (manifestation)
Encyclopedia article (work) manifested as webpage (manifestation)

Original property, manifestation of:

Book (manifestation) manifestation of encyclopedia volume (work)
Website (manifestation) manifestation of encyclopedia volume (work)
Book (manifestation)manifestation of proceedings (work)
Book (manifestation)manifestation of dictionary (work)
Book (manifestation)manifestation of novel (work)

The far more useful case, IMO, is using it for instances to denote relationships between instances of manifestations and instances of work. So if we wanted to find the work that a manifestation pertains to, or several manifestations of the work (using the original property only):

Insect ( Encyclopedia Britannica work)
- instance of encyclopedia article (work)
- author Sir Vincent Brian Wigglesworth
Insect ( Encyclopedia Britannica webpage)
- instance of : webpage (manifestation)
- manifestation of : Insect ( Encyclopedia Britannica work)
- url : http://www.britannica.com/EBchecked/topic/289001/insect
Insect ( Encyclopedia Britannica article)
- instance book section (manifestation)
- manifestation of Insect ( Encyclopedia Britannica work)
- volume II
- pages 200-202

In practical terms many of the work and manifestation properties are in the same wikidata item, in which manifestation of isn't useful but manifested as is slightly useful to the properties herein. As both manifesting a webpage and a book section, it will have a url as well as a volume:

Insect ( Encyclopedia Britannica article)
- manifested as webpage
- manifested as book section
- instance of encyclopedia article
- url http://www.britannica.com/EBchecked/topic/289001/insect
- volume II
- pages 200-202
- author Sir Vincent Brian Wigglesworth

With neither property, using instance of for everything:

Insect ( Encyclopedia Britannica article)
- instance of webpage
- instance of book section
- instance of encyclopedia article
- url http://www.britannica.com/EBchecked/topic/289001/insect
- volume II
- pages 200-202
- author Sir Vincent Brian Wigglesworth

If there is only one work and the manifestations seem to mix properties okay, this is less of an issue. But consider a song: as a work, the composer is generally considered the author, and this would go in the author property. But if the song is published in a book, the "author" is actually usually published as the author of the book. And in a recording of that song? Well the performer is frequently in the author field. If we have a single wikidata item for a song, in the "authors" field do we put the composer, and the author of every book it was in, and every performer that has ever sung it and the information for all those recordings that have been made of it? This is actually what happens to a popular song like Silent Night. It has a semi-large list of performers already. A Nightmare! (Pun intended).

tl;dr Support, and I'll probably mostly use it for instances to link manifestations of a work to the work. Mvolz (talk) 20:47, 25 August 2014 (UTC) Support to match FRBR which is the standard for book metadata. Filceolaire (talk) 21:52, 15 September 2014 (UTC)

Support, it may be useful in some cases to distinguish between a text and a text with a medium. Danneks (talk) 15:59, 29 September 2014 (UTC)

@Micru, Danneks, TomT0m, Mvolz, Filceolaire: Done, with apologies if there was someone I accidentally didn't ping. --Jakob (talk) 21:41, 11 October 2014 (UTC)
