so you mean one graph may say my name is emmanuel and the other may say my name is gustavo, so which is correct?

@eric.d.scott: it really depends on the application and what you’re doing though. If you’re pulling in data from untrusted sources yes you need to care about provenance, and track it. A lot of applications can make a closed world assumption about the data; because they control or manage it, and not worry about it.

There’s a new release of grafter by the way… It now has a small clojure DSL for generating sparql property paths: https://github.com/Swirrl/grafter/blob/master/test/grafter_2/rdf4j/sparql/path_test.clj#L176-L220
