<div lang="en" dir="ltr" class="mw-content-ltr">
A '''property''' describes the data value of a statement and can be thought of as a category of data, for example "color" for the data value "blue". Properties, when paired with values, form a {{ll|Help:Statements|statement}} in Wikidata. Properties are also used in {{ll|Help:Qualifiers|qualifiers}}.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Wikidata currently has {{pages in namespace|property}} properties.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Properties have their own pages on Wikidata and are connected to items, resulting in a linked data structure.

==বৈশিষ্ট্য জ্ঞান==

<div lang="en" dir="ltr" class="mw-content-ltr">
Properties are similar to items in a couple of ways. Like items, each property has a label, a description, and even an alias or aliases that can be added in multiple languages. Properties also have statements that help to more completely describe the property, including [[Special:MyLanguage/Help:Property constraints portal|constraints]] on how the property can be used.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{| class="wikitable" align="right" 
|+ [[Property:P106|P106]] for English, French, and Polish
! Label !! Description !! Alias 
|-
| occupation || occupation of a person || profession; job; work; career
|-
| profession || métier ou occupation d'une personne || métier; occupation 
|-
| zawód || zawód osoby, zobacz także "dziedzina" || <small>(none yet added)</small>
|-
|}
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
However, properties do not have a section on their pages for sitelinks to other Wikimedia projects, and they also do not have external identifiers.
</div>  

<div lang="en" dir="ltr" class="mw-content-ltr">
Each property has a {{ll|Help:Data type|data type}} which defines the kind of values allowed in statements with that property.
</div> 

<div lang="en" dir="ltr" class="mw-content-ltr">
Properties aim to relate one type of entity with another type. The type of item a property should be used on is called its {{Q|Q112036279}} and can be enforced using a {{Q|Q21503250}}. If the data type of an item is an Item, than the type of item that should be the value of the property is called is {{Q|Q112036270}} and can be enforced using a {{Q|Q21510865}}. If the data type is not an Item, the type of a value a property has can be specified with {{P|P10726}}.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Like items, properties also have a unique identifier. While items begin with a Q prefix and are found in the main namespace of Wikidata, properties have a P prefix and are stored in the property namespace.
</div>

==বৈশিষ্ট্য তৈরিকরণ==
{{main|Wikidata:Property creation}}
<div lang="en" dir="ltr" class="mw-content-ltr">
Before a new property is created, it has to be discussed and documented at {{ll|Wikidata:Property proposal|Wikidata:Property proposal}} first. When after some time there are some supporters, but no or very few opponents, the property is created by a {{ll|Wikidata:Property creators|property creator}} or an {{ll|Wikidata:Administrators|administrator}} (see [[Special:ListUsers/propertycreator|List of property creators]]).
After creation, relevant documentation is moved to the corresponding property's talk page, where usage of the property is further discussed.
</div> 

<div lang="en" dir="ltr" class="mw-content-ltr">
When proposing properties, keep in mind that each property should be expected to be used by at least 100 items; if a proposed property cannot be used this many times, it likely should not be added to Wikidata (of course, there are exceptions to this rule).
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
To propose a property, click {{ll|Wikidata:Property proposal|here}} and choose a topic category. Click the blue button "Create request page" and then fill out the provided template with as much information as possible. Make sure to include a possible property name in English (this will be the label), a description, the data type, examples of the type of item that may bear the property, and an example of how the property would be used. Don't worry about getting everything right the first time; that's what the discussion process is for.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
If you are interested in being involved at the property proposal level for a specific subject matter, consider joining or creating a {{ll|Wikidata:WikiProjects|WikiProject}}, a group of contributors who want to work together to improve a particular aspect of Wikidata. These groups often focus on how to best represent the data for a particular area of knowledge.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">

<span id="Editing_properties"></span>
==বৈশিষ্ট্য সম্পাদনা==
{{Warning|1=<span lang="en" dir="ltr" class="mw-content-ltr">You need to be [[Special:MyLanguage/Wikidata:Confirmed users|confirmed]] or [[Special:MyLanguage/Wikidata:Autoconfirmed users|autoconfirmed]] to edit properties.</span>}}

<div lang="en" dir="ltr" class="mw-content-ltr">
Property entities can be edited like {{ll|Help:Item|item entities}} with {{ll|Help:Labels|labels}}, {{ll|Help:Descriptions|descriptions}}, {{ll|Help:Aliases|aliases}}, and statements.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''Property labels''' should be as unambiguous as possible so that it is clear to a user which property is the correct one to use when editing items and adding statements. Properties rarely refer to commonly known concepts but they are more constructs of the Wikidata with specific meanings. Unlike items, property labels must be unique.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''Property descriptions''' are less relevant for disambiguation but they should provide enough information about the scope and context of the property so that users understand appropriate usage of the property without having to consult additional help.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''Property aliases''' should include all alternative ways of referring to the property.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''Example:'''<br/>
:property: [[Property:P161|P161]]<br/>
:label: cast member<br/>
:description: actor performing live for a camera or audience<br/>
:aliases: film starring; actor; actress; starring<br/>
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Label, description, and aliases of a property are first discussed by the community during the property proposal process. Major changes to a property should be discussed on its talk page first.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
See [[Help:Data_type#Changing_datatype]] for changing the datatype of a property.
</div>

<span id="Deleting_properties"></span>
== বৈশিষ্ট্য অপসারণ ==

<div lang="en" dir="ltr" class="mw-content-ltr">
If you think a property should be removed from Wikidata (for example, if is a duplicate of another property in use), you will have to make a request for its deletion. To do so, follow the steps listed at {{ll|Wikidata:Properties for deletion}}.
</div>

<span id="Using_properties"></span>
== বৈশিষ্ট্য ব্যবহার ==

<div lang="en" dir="ltr" class="mw-content-ltr">
Wikidata relies on consistency. For instance, all persons should have common properties whenever possible, whether they are politicians, artists or scientists, living or historical, fictional or not. If you are unsure whether the property you are using is most appropriate for the statement, consult the property's discussion page or ask on [[Wikidata:Project chat]]. An automatically generated list of properties currently supported by Wikidata can be found at [[Special:AllPages/Property:|here]]. Community-maintained lists can also be found at {{ll|Wikidata:List of properties}}.

<span id="Bidirectional_relationships_and_hierarchies"></span>
===দ্বিমুখী সম্পর্ক ও শ্রেণিবিন্যাস===

<div lang="en" dir="ltr" class="mw-content-ltr">
Wikidata does not support automatic bidirectional links ([[phabricator:T51165]]), so some properties need to be added and maintained twice. If, for example, A is a child of B on A's item page, the relation B as the parent of A also needs to be maintained on B's item page.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
In general, only simple hierarchical properties should be recorded as statements. For example, record properties like {{P|40}}–{{P|22}} and/or {{P|25}}, but not properties like ''grandchild–grandparent'', ''niece–aunt'', ''niece–uncle'', etc. Such additional relationships can be derived from the existing data.
</div>

== <span lang="en" dir="ltr" class="mw-content-ltr">Property misuse</span> <span id="misuse"></span> ==

<div lang="en" dir="ltr" class="mw-content-ltr">
Every Wikidata property is intended for a specific purpose. When a Wikidata property is used in a way that goes against the consensus of how the property is meant to be used, we speak of ''property misuse''. Wikidata attempts to combat property misuse with {{ll|Help:Property constraints|property constraints}} and {{ll|Wikidata:WikiProject Schemas|entity schemas}}. If a property is misused because there doesn't exist any good alternative property, {{ll|Wikidata:Property creation|a new property may be proposed}}.
