    Typically useful to create a formatted subset of a Wikibase JSON dump.

    Download dump

    Wikidata dumps

    Wikidata provides a bunch of database dumps, among which the desired JSON dump. As a Wikidata dump is a very laaarge file (September 2020: 55GB compressed), it is recommended to download that file first before doing operations on it, so that if anything crashes, you don't have to start the download from zero (the download time being usually the bottleneck).

    wget -C https://dumps.wikimedia.org/wikidatawiki/entities/latest-all.json.bz2
    cat latest-all.json.bz2 | bzcat | wikibase-dump-filter --claim P31:Q5 > humans.ndjson

    Your own Wikibase instance dump

    You can generate a JSON dump using the script dumpJson.php. If you are running Wikibase with wikibase-docker, you could use the following command:

    cd wikibase-docker
    docker-compose exec wikibase /bin/sh -c "php ./extensions/Wikibase/repo/maintenance/dumpJson.php --log /dev/null" > dump.json
    cat dump.json | wikibase-dump-filter --claim P1:Q1 > entities_with_claim_P1_Q1.ndjson


    This package can both be used as a command-line tool (CLI) and as a NodeJS module. Those 2 uses have there own documentation page but the options stay the same, and are documented in the CLI section


    We are developing and maintaining tools to work with Wikidata from NodeJS, the browser, or simply the command line, with quality and ease of use at heart. Any donation will be interpreted as a "please keep going, your work is very much needed and awesome. PS: love". Donate
