Laurent, the reference node does not _have_ to have a relationship, although it is not recommended not to do so.
Another way to do this is to see if there are any relationships/nodes in use. This is not the official API, but there is the possibility to get a TransactionManager and the number of IDs in use: EmbeddedNeo.getConfig().getNeoModule().getNodeManager().getNumberOfIdsInUse(Nodes.class) This is not exposed in the external API and would require you , but it might help you in your case. We are trying to get the Config API into the 1.0 release, but don't count on it!
