Hi!
What's the URL of the dataset loaded into your
Blazegraph DBMS? Ideally,
we should have this data available from a variety of SPARQL Query
Services [1].
The data is from
https://dumps.wikimedia.org/wikidatawiki/entities/ plus
streaming updates from Wikidata. You can see RDF format description at
https://www.mediawiki.org/wiki/Wikibase/Indexing/RDF_Dump_Format
