A counter field that you add to an index on the parent key field. So you search for the record that has no parent key -- that's the top. Then you search for that record's key in the parent key index -- that will have its children in sibling order. And so forth. I don't do SQL searches, which would probably make this slow, just a local navigation algorithm on the index. You seem to have hit on something similar to my scheme with your self contained descriptions of where nodes live. The records I'm speaking of are just fields holding keys in that uniform structure I speak of, so each record holds the context -- plus the particular "node" key, which I call a link. "Nodes" are actually also metadata -- you don't really get "data data" until you seek attribute values.
