= Wikidata = [[File:Wikidata-logo-en.svg|thumb|right|260px|The [https://wikidata.org Wikidata] logo]] '''[[w:Wikidata|Wikidata]]''' [https://wikidata.org (.org)] is a [[w:knowledge base|knowledge base]], an effort to store and serve structured data to [[Wikimedia]] wikis and to a more limited extent to other parties. Wikidata effort saw the daylight in [[2012]]. The underlying software is the '''[[#Wikibase|Wikibase]]''' which consists of 2 [[Mediawiki]] extensions, the [[mw:Extension:Wikibase Repository|Wikibase Repository]] and the [[mw:Extension:Wikibase Client|Wikibase Client]]. Wikibase allows [[interwiki]] links to be managed with Wikidata removing much contributor annoyanges, redundancy and error-proneness. Wikidata is obviously a very viable source of [[reference]] level data once it is technically possible for non-WMF wikis to access the data items. (See [[#LinkedWiki extension]] for a potential workaround for this limitation) It can be accessed outside of WMF wikis with with * [https://query.wikidata.org/ Wikidata's SPARQL endpoint] using [[SPARQL]] ([[wikidata:Wikidata:SPARQL_query_service/queries|Wikidata advice on how to query]]). * [[mw:Wikidata Toolkit]] is a way for Java programs to access data in the Wikidata repository. * [https://rdflib.github.io/sparqlwrapper/ SPARQL Endpoint interface to Python] * [[wikidata:Wikidata:Database download|Wikidata database download]] * The [https://tools.wmflabs.org/wikidata-game/# Wikidata Game] [[w:gamification|gamifies]] adding information to Wikidata. Main entry point of any Wikidata item is a [[w:JSON|JSON]] dictionary, that has this form: <code>{“labels”: by-language dictionary “descriptions”: by-language dictionary “aliases”: by-language dictionary “claims”: list of property and values “sitelinks”: by-language dictionary}</code> == Lexicographical Wikidata == A '''lexeme''' is a unit of [[w:lexical semantics|lexical]] meaning that underlies a set of words that are related through [[w:inflection|inflection]]. It is a basic abstract unit of meaning,<ref>''The Cambridge Encyclopedia of The English Language''. Ed. [[w:David Crystal|]]. Cambridge: Cambridge University Press, 1995. p. 118. {{ISBN|0521401798}}.</ref> a [[w:emic unit|unit]] of [[w:Morphology (linguistics)|morphological]] [[w:Semantic analysis (linguistics)|analysis]] in [[w:linguistics]] that roughly corresponds to a set of forms taken by a single root [[w:word]]. For example, in [[w:English language|English]], ''run'', ''runs'', ''ran'' and ''running'' are forms of the same lexeme, which can be represented as <span style="font-variant:small-caps; text-transform:lowercase;">RUN</span> (Wikipedia on 2019-12-29) Since 2018, Wikidata has also stored a new type of data: words, phrases and sentences, in many languages, described in many languages. This information is stored in new types of entities, called '''Lexemes''' ('''L'''), '''Forms''' ('''F''') and '''Senses''' ('''S''').<ref>[[wikibooks:SPARQL/WIKIDATA Lexicographical data]]</ref>. This is enabled by [[mw:Extension:WikibaseLexeme|the WikibaseLexeme extension]]. * [[wikidata:Wikidata:Lexicographical_data/Documentation|The main documentation page for lexicographical data on Wikidata]] * [[wikidata:Wikidata:Tools/Lexicographical data|Wikidata's list of lexicographical properties and tools using the lexicographical data]] * [[wikibooks:SPARQL/WIKIDATA Lexicographical data|Wikibook on Wikidata's lexicographical data]] == Useful information == * [[wikidata:Wikidata:Tools/External_tools|Wikidata's list of external tools that make use of Wikidata's knowledge]] '''More info''' * [[m:Wikidata|Metawiki on Wikidata]] * [[w:Wikipedia:Wikidata|Wikipedia advice on Wikidata issues]] == Wikibase == [[File:Wikibase_logo.png|thumb|right|250px|The [http://wikiba.se/ Wikibase] logo]] '''[[mw:Wikibase|Wikibase]]''' [http://wikiba.se/ (wikiba.se)] is a system for storing and querying structured data that powers [[Wikidata]] and other wikis. Wikibase consists of two extensions: :# [[mw:Extension:Wikibase Repository|Wikibase Repository]] that allows a wiki to work as a repository for structured data. :# [[mw:Extension:Wikibase Client|Wikibase Client]] that allows a wiki to access structured data from a repository. The client can work only with repository databases it can access so they must be on the same machine or the same load balancer. === Installation of Wikibase === [[mw:Wikibase/Installation|Wikibase installation instructions at Mediawiki.org]] and [[mw:Wikibase/Installation/Advanced_configuration|advanced configuration of Wikibase]]. The installation instructions assume you are installing the dependencies with [[mw:Composer|Composer]], a PHP package manager that makes the installation of dependencies easy. === Useful extensions in conjunction with Wikibase === * [[mw:Extension:ArticlePlaceholder]] makes article placeholders from repository data and invites users to create the article. * [[mw:Extension:UniversalLanguageSelector]] is recommended to work in conjunction with Wikibase for user comfort. == Alternative to using Wikibase Client == * [[#LinkedWiki extension]] can be configured to access multiple SPARQL endpoints. === Useful information === * [[mw:Wikibase/DataModel|The data model used in Wikibase]] (thorough) and [[mw:Wikibase/DataModel/Primer|the primer on the data model]] (quick access) * [https://github.com/wikimedia/mediawiki-extensions-Wikibase/blob/master/docs/federation.wiki Information on the federation of Wikibase at Github] * [https://phabricator.wikimedia.org/T159240 Phabricator Task to "Document how to set up federated Wikibase instances"] * [https://phabricator.wikimedia.org/T196997 Phabricator Task to "Wikidata/Wikibase federation and distribution"] and the [https://docs.google.com/document/d/1YYIuQzcWz2cH9zTUbbfiBrTecVxMWAu3_9-U4DcKzEU/edit#heading=h.z49pje934vur Google Docs document charting out the task] ----
