Vikiveri üzerinde sağlanan verilerin kopyalarının indirilmesine olanak sağlar.

Vikiverideki yapılandırılmış verilere erişmenin bir çok farklı yolu vardır, bunlar tam veritabanı dökümü gerektirmez.

Veritabanı dökümleri

There are several different kinds of data dumps available. Note that while JSON and RDF dumps are considered stable interfaces, XML dumps are not. Changes to the data formats used by stable interfaces are subject to the Stable Interface Policy.

JSON dökümleri (önerilir)

Tüm Vikiveri varlıklarının liste halini içeren JSON dökümü https://dumps.wikimedia.org/wikidatawiki/entities/ adresinde bulunabilir. Haftalık olarak oluşturulmaktadırlar.

Bu önerilen döküm biçimidir. Vikiveri varlıklarının nasıl temsil edildiği hakkında bilgi edinmek için JSON yapı dökümantasyonuna bakabilirsiniz.

Hint: Each entity object (data item or property) is placed on a separate line in the JSON file, so the file can be read line by line, and each line can be decoded separately as an individual JSON object.

Note that the files are using parallel compression, which means that some decompressors cannot reliably unpack the files. If you are using Windows you can use e.g. Bzip2.

JsonDumpReader is a PHP library for reading the dumps.

RDF dumps

First, canonical RDF dumps using the Turtle format can be found under https://dumps.wikimedia.org/wikidatawiki/entities/. The mapping is described here. These full statements are noted as all.

Secondly, so called truthy dumps are provided. They use the nt format. They are in the same format as the full dumps, but limited to direct, truthy statements. Therefore, they do not contain meta data such as qualifier and references.

The complete dumps together contain all entity information in Wikidata with the exception of order (of aliases, of statements, etc.), which is not naturally represented in RDF. Simplified dumps encode statements that have no qualifiers as single RDF triples (references are omitted).

XML dumps

Full XML dumps of Wikidata can be found at https://dumps.wikimedia.org/wikidatawiki/.

Warning: The format of the JSON data embedded in the XML dumps is subject to change without notice, and may be inconsistent between revisions. It should be treated as opaque binary data. It is strongly recommended to use the JSON or RDF dumps instead, which use canonical representations of the data!

Incremental dumps (or Add/Change dumps) for Wikidata are also available for download. These dumps contain stuff that was added in the last 24 hours, reducing the need of having to download the full database dump. These dumps are considerably smaller than the full database dumps

They can be found at https://dumps.wikimedia.org/other/incr/wikidatawiki/.

Lexicographical data

Lexical data dumps are not yet available for download. See corresponding Phabricator ticket.

Old JSON and RDF dumps

Old RDF and JSON dumps can be found on the Internet Archive (Q461):

Data model

The data model can be looked up here. The data model describes the fundamental building blocks of Wikidata's data.

Database schema

An overview over the schema of the database can be found at this page. (This is not the schema of the data in Wikidata.)
