I am not sure about this, sibling_id is the array-index, when I understand. What happens in case a dataset changes, for example an item is removed from a cluster, in that case all the other datasets should need revisiting to have this property changed. For my idea, the array-index is volatile and calculated at the moment of need. Bert
