Ok, fair enough. I suspect the typo in the sparql query doing the key join isn't helping :( The SPARQL is more paragraph based. We are looking for ?j a :Person

Ok, fair enough. I suspect the typo in the sparql query doing the key join isn't helping :( The SPARQL is more paragraph based. We are looking for ?j a :Person named 'Jenifer' and ?p a person who is a friend of ?j . Both need to be interested in graph technology. This kind of sections of defining a query ends up easier when the relations are multitude between nodes. e.g. friends, colleagues and past having non identical lunch preferences.
