> in which case you might want to avoid Fuseki entirely and just work with TDB I can issue SPARQL queries directly at TDB2 without using Fuseki? My original problem still stands tho :) Is "s-put" the only way to replace a graph in a TDB2 dataset? Is there any CLI tool (non http) that can manipulate a TDB2 dataset to replace a graph with another (eg. replace wikidata with a new dump)?
