> //if we save the graph here the backend might just store one tripleHi Reto, Sorry I don't have time to reply fully, but I repeat what I said earlier that it is most unusual for any RDF database to just store one triple in that case. In the context of Java, if you create 5 BlankNode objects and add them to the database as part of Triples, then the database should store 5 BlankNodes references and internally make sure that they are distinct. Do you have examples of other RDF database systems that operate according to the Clerezza principle?
