I got the answer of my question of my experimentation. I obtained a solution in the edit window of query (in the front end). I just selected every graph, selected all the triple inside it and deleted. Saving this would result is deleting all entries. The fron end would update and remove all

Hi, I added a new dataset in Fuskei 2.4.0 and added one line tdb:unionDefaultGraph true; at the end of the configuration ttl file. This started working and gave desired results for classes in my OWL file. One question regarding graphs loaded into my persistent dataset that I had
