Is/was aEdit

Latest comment: 10 years ago3 comments3 people in discussion

If I understand correctly, at some point we'll have a way to use qualifiers to specify the time that any attribute was held, so wouldn't it make sense to change the label of this to "is/was a"? --Yair rand (talk) 07:11, 5 February 2013 (UTC)Reply[reply]

I've started a discussion about this property here. --Kolja21 (talk) 08:55, 5 February 2013 (UTC)Reply[reply]
This is meant to be used in a very limited way for statements we want to make for which a property is inappropriate. For example, "<Canada> is a <country>". It might be worth re-labelling the property to "is an instance of" (so, "<Canada> is an instance of <country>". It is not meant for wide-spread use. Note that Property:P107 exists for a sub-set of this property (stating that the subject is an instance of "person", "name", "organisation", "event", "work", "term" or "place"), and should be used instead of this property for those.

UsageEdit

How is this supposed to be used? Should it be used only for describing an item in it's entirety (Marie Curie "is a" person) or describing every aspect of it (Marie Curie "is a" person, spouse, mother, child, woman, Nobel winner, chemist,...) Template:Unsigned

Not localizableEdit

Latest comment: 5 years ago2 comments2 people in discussion

This property is not very easy to translate/localize. For languages that have genders (e.g. German), there is no one translation for "one". I also share the concerns of Janjko above. Jon Harald Søby (talk) 18:47, 5 February 2013 (UTC)Reply[reply]

+1 the Chinese shows "分类" (means "Category" in English), but a apparently "instance_of" is quite different from "Category" and is a common mistake to confuse them two. Xinbenlv ([[User talk:Xinbenlv|int:Talkpagelinktext]]) 00:59, 22 March 2018 (UTC)Reply[reply]

Problem Localizing to PersianEdit

Latest comment: 10 years ago4 comments4 people in discussion

"is a" is in Persian "می‌باشد" and the verbs are coming in Persian after the nouns.

so the sentence like is a sovereign state will be

کشور مستقل می‌باشد

and not

می‌باشد کشور مستقل

how can we implement these kind of staffs. or it is not a right place! --Pouyana (talk) 20:01, 7 February 2013 (UTC)Reply[reply]

This particular property may need to be rethought, but for this kind of problem, I would think the best solution would be to find a phrase it so that word order is ok. If that is not possible, you may want to leave a message on Wikidata:Contact the development team. Cheers. --Zolo (talk) 06:30, 8 February 2013 (UTC)Reply[reply]
Perhaps renaming the property "type" or another noun would help. -- Ypnypn (talk) 21:24, 8 February 2013 (UTC)Reply[reply]
You don't need an exact translation on word-level, you can use a phrase but that phrase must be unique and usable in the property parser function. Well basically, you don't want a very long phrase as it is cumbersome to type. See m:Wikidata/Notes/Inclusion syntax v0.3. Jeblad (talk) 21:54, 8 February 2013 (UTC)Reply[reply]

Semantical nonsenseEdit

Latest comment: 10 years ago9 comments8 people in discussion

The way this property is used seems like nonsense. Where we mean that the item is a republic, we should use property "state system". Where the item is a person and we tell Wikidata that this person is a scientist, we should use propert "occupation". And so on. Wizardist (talk) 20:56, 8 February 2013 (UTC)Reply[reply]

I think this is an eseencial property. It just filters items in the crudest way. --NaBUru38 (talk) 21:18, 8 February 2013 (UTC)Reply[reply]
It's meant to be used for "person" or "place" or something. Anything more detailed goes in other properties. -- Ypnypn (talk) 21:25, 8 February 2013 (UTC)Reply[reply]
This property is for define the type of the item. In your first example is a State, in the second one is a person. --β16 - (talk) 22:01, 8 February 2013 (UTC)Reply[reply]
Then maybe we call this property a normal noun? Like "type"? Wizardist (talk) 03:41, 9 February 2013 (UTC)Reply[reply]
Yes probably, see Wikidata:Property_proposal#Main_type_of_item_.28entity.29_.2F_Art_des_Objekts_.2F_Type_principal and Wikidata_talk:Property_proposal#is_a. --Zolo (talk) 08:34, 9 February 2013 (UTC)Reply[reply]
What if we use this property for the "entities" of GND (person, name, corporate body, event, work, term, place)? --Sannita - not just another it.wiki sysop 12:43, 9 February 2013 (UTC)Reply[reply]
+1. Imho "main types of items" is the better choise. This seems to be the original concept of Wikidata:Infoboxes task force. --ThorstenX1 (talk) 21:56, 10 February 2013 (UTC)Reply[reply]
+1 to rename to 'type' or 'itemtype', or something similar with much more specific meaning than 'is a'. Now we can have object.GetType() :) --Yurik (talk) 10:36, 13 February 2013 (UTC)Reply[reply]
There is now Property:P107 that is better defined that this one - though implementation details still remain to be worked out. I think items using this property should be changed so that they use more specific property (like Property:P106 and Property:P107) and then this property can be deleted.

Prevent or avoid "is a"Edit

Latest comment: 10 years ago3 comments3 people in discussion

I think this property should never be used for people. A person could be anything. "Occupation", "Title", "sex", etc, are more specific. Is it possible to prevent it from beeing used for main type p?

Everytime a more specific property is available "is a" should be avoided. Organisations and works, the "type" property might be used instead.

A similar vague property, suggested by the wikidata developers, was "is in", for example for places, but until now, more specific properties (e.g. "continent") has been used. Mange01 (talk) 22:46, 14 February 2013 (UTC)Reply[reply]

This property should really be deleted all together. There is a entity type property (the name is under discussion, vote on the talk page), that should specify person/object/event/etc. --Yurik (talk) 22:51, 14 February 2013 (UTC)Reply[reply]
I'm agree to delete this property (is too much generic), but it is very useful for astronomic object, to distinguish stars, planets, satellites, galaxies... For example templates of Italian Wikipedia (astronomical object and non stellar objects), need a parameter to distinguish the different types of objects managed by them. Is it possible, after discussion, to undelete the property astronomical object? Its deletion was caused for the existence of this property! --Paperoastro (talk) 08:51, 16 February 2013 (UTC)Reply[reply]

Delete or renameEdit

Latest comment: 10 years ago5 comments5 people in discussion

{{delete|This property does not help with the classification of the entities in wikidata because its meaning is too ambiguous. The Property:P107 (entity type) has a much more precise meaning and follows a well established classification scheme by only allowing specific values: person, organization, event, work, term, and place. All items with this property should be changed (by a bot?) before deleting. --Yurik (talk) 05:13, 16 February 2013 (UTC)}}Reply[reply]

(Please see description in the box above, and comment here)

Please don't put deletion template to a talk page, as talk pages are not to be deleted. This template is for deletions that are not likely to be questioned. You should list the property page itself on RfD where it may be discussed. Bináris (talk) 16:40, 16 February 2013 (UTC)Reply[reply]

The aim of this property is to reflect relationships in an ontology, typically a hierarchical system such as a library classification system, making it possible for computers to inteprete knowledge base. But there are many alternative ontologies and competing standards. So I think that it should be supplemented by several of ontology specific properties. We may start with changing name of P31 from "is a" to "[is an ]instance of (GND entity)" or "GND ontology instance of". See http://d-nb.info/standards/elementset/gnd# for an authoritative source. A (temporary?) problem is that some of the GND entities have no Wikipedia article yet, and it is not allowed to created the item at Wikidata. (A similar discussion is ongoing at Property talk:P107 - "Wikidata main type of item"="GND ontology high level entity".) Mange01 (talk) 20:25, 17 February 2013 (UTC)Reply[reply]
Template:Oppose We renamed P107 already a couple of times. Now to start mixing different ways of classification can't work. --Kolja21 (talk) 21:33, 17 February 2013 (UTC)Reply[reply]
I think is-a is a “good“ property, we just have to invoke some rules. E.g. I added the property is-a elementary particle and is-a fermion to Q2225 (electron). I think this is helpful for queries in future like „List all elementary particles“ or „List all fermions“ etc.
I heard from a thing called „InstanceOfSnack“. I don't really understand the difference between this instance and the is-a-property. Is it only a technical difference?
We should invoke the rule “If there exists a more specific relation property than is-a, this specific relation property must be used“. Example: Marie Curie is-a mother and is-a spouse. But instead of using these properties we should use Marie Curie is-mother-of/father-of (Property:P40) Irène Curie and is-spouse-of (Property:P26) Pierre Curie.
The properties itself then get the generalized property: is-mother-of is-a is-a or something like that (if technical possible).
In general this “is-a“ properties will lead to the same insane discussions and problems what we all face for categories in the Wikipedia. Because is-a is nothing else than categorisation.--Svebert (talk) 11:07, 14 March 2013 (UTC)Reply[reply]

HierarchyEdit

A short reply without writing a history of the debate about P31/P107/etc: One level of "hierarchy" is enough. Espeso (talk) 15:02, 14 March 2013 (UTC)Reply[reply]
The deepest I suggest, right?
Is there some template or comparable to define such “rules“ for a property?--Svebert (talk) 15:45, 14 March 2013 (UTC)Reply[reply]
Yes, the deepest.
No, there are no (extended) templates describing properties. Some of the simpler properties have the template row from WD:P copied to the property talk page. But with this particular property, any attempt to formalize some usage would probably be met with resistance by... someone else who favors a different property. My own opinion is that since this is a wiki, and barely starting at that, let competition among properties prevail and see what happens. Espeso (talk) 17:11, 14 March 2013 (UTC)Reply[reply
