Docker image holding an installation of the Blazegraph Wikidata query service.
Full Description

Docker image holding an installation of the Blazegraph Wikidata query service to support the QALD-7 benchmarking activities. The image requires a populated Blazegraph journal to run. The journal containing a snapshot of Wikidata from 09 Jan 2017 to be used for the QALD-7 Task 4 can be found on the HOBBIT project FTP server:
http://hobbitdata.informatik.uni-leipzig.de/qald7/wikidata-en/blazegraph-jnl/blazegraph.jnl

To run the service, the directory containing the blazegraph.jnl file must be mounted to the /blazegraph-data path on the docker image. For example, the command to run the Wikidata query service with this image can be the following:

docker pull metaphacts/wikidata-qald-7:latest
docker run -d --name wdqs --env WDQS_MODE=RUN_NO_SYNC -v /var/myblazegraphdir:/blazegraph-data metaphacts/wikidata-qald-7:latest

For testing with the QALD-7 queries, it is important to set the WDQS_MODE to RUN_NO_SYNC to ensure that the queries are executed against the correct snapshot of Wikidata.
