[[<tvar|about-wd>Special:MyLanguage/Wikidata:About</>|Wikidata]] is a multilingual free knowledge base about the world that can be read and edited by humans and machines alike. It provides data in all the languages of the Wikimedia projects, and allows for the central access to data in a similar vein as [[<tvar|commons>c:Special:MyLanguage/Commons:Welcome</>|Wikimedia Commons]] does for multimedia files, it is also used by many other websites. The data on Wikidata is added by a community of volunteers both manually and by using software, much like other Wikimedia projects including Wikipedia.

<!--T:19-->
Wikidata has millions of {{<tvar|item>glossary|item</>|items}}, each representing things like a person, a place, an artwork, an abstract concept, or some other type of entity. Each item has statements (key-value pairs), each statement in turn consisting of a {{<tvar|pr>glossary|property</>|property}} such as "birth date", and the appropriate value for the item. Properties have their own pages on Wikidata and are connected to items, resulting in a linked data structure. There can also be statements for {{<tvar|ext-id>glossary|External identifier</>|external identifiers}}, such as a VIAF IDs.

<!--T:20-->
Wikidata is hosted by the [[<tvar|wmf>wmf:</>|Wikimedia Foundation]], a nonprofit charitable organization dedicated to encouraging the growth, development and distribution of free, multilingual, educational content, and to providing the full content of these wiki-based projects to the public free of charge.</translate>

<translate><!--T:22-->
Wikidata focuses on a basic level of useful information about the world and links to other resources for specialized data on the subject. Sources for data on Wikidata must be:

<!--T:23-->
* Reliable
* Publicly available

<!--T:24-->
The best way to find out which parts of your data is suitable for Wikidata is [[<tvar|contact>#contact-community</>|to talk to the Wikidata community]].</translate>

==Why add data to Wikidata== <!--T:25-->

<!--T:26-->
There are many reasons to add data to Wikidata including:</translate>

<translate>
===Improve open knowledge=== <!--T:29-->

<!--T:30-->
Wikidata hosts data that can be used on Wikimedia projects and beyond. By adding data to Wikidata you create a framework and checklist to help your topic to be well covered and up to date in all Wikimedia projects in many languages.</translate>

===Make your data more useful for yourself and others=== <!--T:33-->

<!--T:34-->
Under Tim Berners-Lee's (the inventor of the World Wide Web) [http://5stardata.info/en/ 5-star Open Data plan], making your data available as a spreadsheet is rated as 2 stars, but adding it to Wikidata will rate it as 5 stars, allowing it to benefit from the [https://en.wikipedia.org/wiki/Network_effect network effect]. By adding data to Wikidata it becomes more useful, you can:

<!--T:35-->
* Combine it with other data
* Use Wikidata tools to explore the data
* Visualise your data along with data from other sources</translate>

==How to add data to Wikidata== <!--T:65-->

<!--T:66-->
The process of adding Wikidata can be technically challenging but the Wikidata community is very happy to discuss with you the best approach and offer assistance where needed. The basic process is:

<!--T:67-->
# Contact the Wikidata community describing what data you have and would like to include in Wikidata.
# Decide with the Wikidata community what data is suitable to import.
# Work with the Wikidata community to import the data.
# Keep the data up to date or share the resources needed for others to do so.
</translate>

===1. Contact the Wikidata community=== <!--T:68-->
</translate>
{| cellpadding="10" cellspacing="0"
|-
|[[File:Wikimedia Community Logo.svg|100px|link=]]
|
<translate><!--T:69-->
There is a central noticeboard for contacting the Wikidata community called [[Wikidata:Project chat|Project chat]].

<!--T:70-->
# [<tvar|link-acc>//www.wikidata.org/w/index.php?title=Special:UserLogin&returnto=Wikidata%3AMain+Page&type=signup</> Create your own Wikimedia account] (do not use the name of an organisation in the title).
# Make sure you are logged in
# Go to the [[Wikidata:Project chat|Project chat]] page.
# Click the blue '''Start a new discussion''' button.
# Write a message and make sure to include a title in the title line.
# Sign the message by writing <tvar|sign><nowiki>~~~~</nowiki></> at the end of your message.

You can also use [[WD:IRC|IRC]] or [[WD:Telegram|Telegram]].

===2. Decide with the Wikidata community what data to import=== <!--T:72-->

<!--T:73-->
Wikidata does not include all data available but just a useful subset. Please refer to our [[<tvar|notability>Special:MyLanguage/Wikidata:Notability</>|notability criteria]] for the minimum requirements.</translate>
{{Anchor|work-with-community}}
<translate>
===3. Work with the Wikidata community to import the data=== <!--T:74-->

<!--T:75-->
There are several ways to add data to Wikidata including</translate>

{| cellpadding="10" cellspacing="0"
|-
|[[File:High-contrast-document-save-as.svg|50px|link=]]
|
<translate>
====Manual data entry==== <!--T:76-->

<!--T:77-->
Everyone can add data to Wikidata [[<tvar|help-items>Special:MyLanguage/Help:Items</>|manually]].</translate>
|-
|}

{| cellpadding="10" cellspacing="0"
|-
|[[File:High-contrast-document-properties.svg|50px|link=]]
|
<translate>
====Online tools==== <!--T:78-->

<!--T:79-->
There are a number of online tools to help with the import of data into Wikidata. Some of them that support specific workflows for data imports are:</translate>
* <translate><!--T:80--> [[<tvar|meta>meta:Special:MyLanguage/Mix'n'match</>|Mix'n'match]] contains lists of important concepts from reliable sources and allows to match the names to Wikidata entries with one click. It is possible to get your list included. Read [<tvar|blog>http://magnusmanske.de/wordpress/?p=114</> the blogpost about the motivation behind Mix'n'match].</translate>
* <translate><!--T:81--> [[<tvar|wp-pst>Special:MyLanguage/Wikidata:Primary sources tool</>|The Primary Sources Tool]] allows for a curation workflow for data donations to Wikidata, where Wikidata editors can review, edit, or reject data offered to the community. It was initially developed for datasets from [[<tvar|wp-freebase>Wikidata:WikiProject Freebase</>|Freebase]], but can be used for any collection of very large non-curated datasets.</translate>
* <translate><!--T:96--> [[<tvar|wp-qs>Special:MyLanguage/Help:QuickStatements</>|QuickStatements]] allows users to create items and upload lists of statements based on input in tab-separated format exported from spreadsheets</translate>

|

<translate>

====Wikidata API==== <!--T:82-->

<!--T:83-->
[<tvar|link>//www.wikidata.org/w/api.php</> The Wikidata API] is a web service that provides convenient access to wiki features, data, and meta-data over HTTP.</translate>
|-
|}

{| cellpadding="10" cellspacing="0"
|-
|[[File:High-contrast-contact-new.svg|50px|link=]]
|

<translate>
====Bots==== <!--T:84-->

<!--T:85-->
[[<tvar|wd-bot>Special:MyLanguage/Wikidata:Bots</>|Bots]] (also known as robots) are tools used to make edits without the necessity of human decision-making. Bots on Wikidata can add interwiki links, labels, descriptions, statements, references, and can even create items, among other things. We also collect [[<tvar|wd-bot-creating>Special:MyLanguage/Wikidata:Creating a bot</>|hints and inspiration for your own code to import data with a bot]].</translate>
|-
|}

<translate>

===4. Keep the data up to date=== <!--T:114-->
</translate>

{| cellpadding="10" cellspacing="0"
|-
|[[File:High-contrast-edit-clear.svg|50px|link=]]
|
<translate>
<!--T:115-->
Wikidata aims to share data with people and machines around the world for decades. Although some data may seem timeless, your import is likely to contain data that at some point will no longer be valid or complete. '''If the data is not maintained, it can not only lose its value, but also become misinformation'''.

<!--T:116-->
Unless you have made an easily repeatable data import, please:
* provide documentation, scripts and other technical resources under a free license so that the community can easily keep Wikidata in sync with the data source from now on, or
* take responsibility for maintaining the data yourself.

<!--T:117-->
One way to motivate yourself to maintain the data is to use it. Be sure to take advantage of Wikidata's potential for your benefit.
