Wikidata Query Service/Implementation/Standalone

WDQS can be run as a service for any Wikibase instance, not just Wikidata. You can still follow the instructions in the documentation, with the following changes:

To generate the dump of your database, use  script in the   directory of Wikibase extension. Depending on your requirements, you may still want to run  script, or you may load the resulting RDF directly into the database.

Required setup
So far, the following conditions should be fulfilled by Wikibase instance for WDQS to work properly: Given Wikibase install top URL as ,
 * RecentChanges API should be accessible at
 * Entity data dump should be accessible at  for entity.

If your Wikibase instance has different URL scheme, the recommended way is to create web server redirects for these two, as these parts are not customizable yet. See below about the URL customization.

You can also separately set Wikibase entity concept URL. The assumptions are, given base URL as :
 * The entity prefix is
 * The data prefix is

You can verify those looking at  and   prefixes in the entity dump URL above, e.g. https://www.wikidata.org/wiki/Special:EntityData/Q4.ttl

WDQS Configurations
Two main things you may need to change are Wikibase endpoint (the URL at which your Wikibase instance is accessible) and concept URI (the URI which prefixes the RDF URIs describing data in your instance). Note that these by default are related but are controlled independently, and do not have to match. By default both settings are set up to match Wikidata data.

If you're running a copy of Wikidata but on your own domain, you may need to change Wikibase endpoint. If you are running your own dataset, you also need to change concept URI.

Setting Wikibase endpoint
This setting controls the URL at which Wikibase instance is found. See above for the list of URLs that are expected to work relative to this URL.

For Updater: For Munger:
 * Use  option when running Updater to set up Wikibase URL.
 * No changes are needed since Munger does not communicate with Wikibase

For Blazegraph: For WDQS GUI:
 * No changes are needed since Blazegraph does not communicate with Wikibase
 * ??? Set up Wikibase endpoint

Setting concept URI
For Munger:


 * Use  option when running Munger. The rules for the URL are the same as for Update above.

Example: bash munge.sh -f mydump.ttl.gz -d data/split -- --conceptUri https://my-wikibase:8081 For Updater:


 * Use  option when running Updater. The URL should match the one seen in the TTL export in   prefix, e.g. if the prefix is defined as:   then the URL will be   Example:

bash runUpdater.sh -n wdq -- --wikibaseUrl https://my-wikibase:8081 --conceptUri https://my-wikibase:8081 For Blazegraph: For WDQS GUI:
 * Set  Java property when running Blazegraph. If you only change hostname, you can use   instead. Example:
