TASK DESCRIPTION I'm trying to get a local, standalone Wikibase with Wikidata Query Service enabled setup together (so that I can potentially teach it to others for educational purposes). I've been documenting everything up to this point to the best of my ability, but I've hit a wall. Because it's a standalone instance, I've had to combine aspects of other guides here <https://github.com/wikimedia/wikidata-query-rdf/blob/master/docs/getting-started.md> and here <https://www.mediawiki.org/wiki/Wikidata_Query_Service/Implementation/Standalone>. A hope to write a guide of my own after I get things up and running. Basic info: - Operating System: Ubuntu 20.04.4 LTS (GNU/Linux 5.13.0-1022-aws x86-64) - MediaWiki Version: 1.37.2 I've established that all components of MediaWiki and Wikibase are working as intended using the various implementation tests. In order to dump the RDF data I've done the following (there's only one entity in the instance): php /var/lib/mediawiki/extensions/Wikibase/repo/maintenance/dumpRdf.php --server http://localhost:400 --output /var/lib/mediawiki/extensions/wikidata-query-rdf/dist/target/service-0.3.111-SNAPSHOT/data/wikibase-05072022-all.ttl Then I go in and delete `schema:name` or `skos:prefLabel` from the `ttl` doc manually because it will fail to load correctly otherwise. I'm not sure if there is a workaround for this, but since it's only one entity, it takes like 2 seconds, so it isn't a huge deal right now. Next I load Blazegraph with: sudo BLAZEGRAPH_OPTS="-DwikibaseConceptUri=http://localhost:400"; bash /var/lib/mediawiki/extensions/wikidata-query-rdf/dist/target/service-0.3.111-SNAPSHOT/runBlazegraph.sh This works with no errors. Then I preprocess the `ttl` using munge: sudo bash /var/lib/mediawiki/extensions/wikidata-query-rdf/dist/target/service-0.3.111-SNAPSHOT/munge.sh -f /var/lib/mediawiki/extensions/wikidata-query-rdf/dist/target/service-0.3.111-SNAPSHOT/data/wikibase-05072022-all.ttl -d /var/lib/mediawiki/extensions/wikidata-query-rdf/dist/target/service-0.3.111-SNAPSHOT/data/split -- --conceptUri http://localhost:400 This works with no errors. Following that, I load in using: sudo bash /var/lib/mediawiki/extensions/wikidata-query-rdf/dist/target/service-0.3.111-SNAPSHOT/loadRestAPI.sh -n placeholdernamespace -d /var/lib/mediawiki/extensions/wikidata-query-rdf/dist/target/service-0.3.111-SNAPSHOT/data/split Finally, I run: sudo bash /var/lib/mediawiki/extensions/wikidata-query-rdf/dist/target/service-0.3.111-SNAPSHOT/runUpdate.sh -n placeholdernamespace -- --wikibaseUrl http://localhost:400 --conceptUri http://localhost:400 This

as intended. I'm wondering if perhaps I've done something wrong during the loading process? Or if something is not running correctly? Any help at all would be much appreciated and I can provide more information if necessary.
