Thanks Heath, for trying to explain to me. It is still not clear to me, please allow me one question.
Since archetype_node_id's are not unique inside an archetype, even paths are not unique, from a programmers point of view: Please correct me if I am wrong. There is only one way to create the data-set which represents the archetype, that is Take the root object from an archetype (which is the locatable rm-object), and iterate to the properties, on an object oriented way, not necessarily using the archetype_node_id's That is OK, but my question is then: what is the function of the archetype_node_id? That I don't understand Thanks Bert
