Hi! I'm interested in using SPARQL for my own Wikibase installation. But, I was getting errors in the munge step.
To reproduce the problem, I set up a new Wikibase instance and tried to load it into wikidata-query-rdf. It has only one item, one property, and one statement. First I used the included dumpRdf.php to create the RDF file, attached. Then I did the munge step. It produced the errors, attached. I don't understand why there is "Unrecognized subjects" when the subjects listed do match the patterns, "Expected only sitelinks and subjects starting with http://www.wikidata.org/wiki/Special:EntityData/ and http://www.wikidata.org/entity/"; I don't understand what is the revision id it is looking for. What is the proper procedure for indexing? If necessary, I can code in Java and fix the tools. I just need an overview on how this system works. Thanks! Regards, Miguel
