How do you create a new blank node when inserting a triple? It seems from the dev guide for 11g that you give the bnode name. How would I create a name that is not already in use? Or is there a way of asking the insert to create a new one?
To insert a triple with a new blank node, user needs to use a blank node label that has not yet been used in the target semantic (RDF) model. One could use database sequence objects (useful in a concurrent setting) or other similar means to generate new labels and then use them to construct triples to be inserted.
