It is an implementation of triplestore technology.

It describes the logic of [[SPARQL]] queries, that are built and executed via the [[Wikidata Query]] or related tools. The model describes how the data is structured, and how queries can be constructed. == Query logic choices == You can basically choose between two types of queries, depending on the item values you base your query on: * ''object based queries'' (default), that search subjects having certain statements * and ''subject based queries'', to search related objects based on a subject item. You can query with and without qualifiers: * When you want to execute ''straight queries'', without qualifiers, you can use straight WDT property type filters. * When you want to ''query with qualifiers'', you heed to use the P, PS, and PQ property type filters. You can split WDT type filters into a combination of P and PS type queries. Then you go through intermediate WDS statements. Here you have the additional possibility to query for references and values. == Example queries == === Straight queries === ==== Straight object based query ==== An object based query is searching for all subject that have a link with the object. List all persons having a relation with Guido Gezelle and an nlwiki page.<syntaxhighlight lang="sparql"> SELECT ?item ?itemLabel WHERE { SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],mul,en". } ?item wdt:P3342 wd:Q336977. { ?articleplus schema:about ?item; schema:isPartOf <https://nl.wikipedia.org/>. } } </syntaxhighlight>[https://w.wiki/TbVM Try!] ==== Straight subject based query ==== A subject based query starts from the subject, and ''cascades'' through its data connections. List all relations of Guido Gezelle, having an nlwiki page.<syntaxhighlight lang="sparql">SELECT ?item ?itemLabel WHERE { SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],mul,en". } wd:Q336977 wdt:P3342 ?item { ?articleplus schema:about ?item; schema:isPartOf <https://nl.wikipedia.org/>. } }</syntaxhighlight>[https://w.wiki/TbVP Try!] === Queries with qualifiers === ==== Object based query with qualifiers ==== An object based query is searching for all subject that have a link with the object.
