Wikidata Query Service/Implementation

Labs Deployment (beta)
Note that currently deployment is via git-fat (see below) which means it may not work on labs. In that case the scripts have to be deployed manually. This can be done as follows: See also Wikidata Query service beta.
 * 1) Check out   repository
 * 2) Run git-fat pull to instantiate the binaries
 * 3) rsync the files to deploy directory

Production Deployment
Production deployment is done via git deployment repository. The procedure is as follows: The puppet role that needs to be enabled for the service is.
 * 1)   the source repository.
 * 2)   in the source repository - this deploys the artifacts to archiva. Note that for this you will need repositories   and   configured in   with archiva username/password.
 * 3) Install new files (which will be also in  ) to deploy repo above. Commit them. Note that since git-fat uses archiva as primary storage, there can be a delay between files being deployed to archiva and them appearing on rsync and ready for git-fat deployment.
 * 4) Run deploy procedure as described in Trebuchet docs.

Services
Service wdqs-blazegraph runs the Blazegraph server.

Service wdqs-updater runs the updater. Depends on wdqs-blazegraph.

Upgrading Blazegraph

 * 1) Use script buildwmf.sh to create Blazegraph binaries. Note that you need to update VERSION in the script. Also note that JAVA_HOME should point to Java 7 home directory (production hosts do not have Java 8 yet).
 * 2) Use instructions in source repo to upload the new binaries to archiva.
 * 3) Update Blazegraph version in pom.xml in the source.
 * 4) Rebuild/redeploy production packages as described above.
