That sounds fine to me. > New York's settlement hierarchy is very messy indeed, and indeed > not quite hierarchical. I have not explained myself well enough. Each state, more or less, has a set of rules about governments and boundaries. Separate from any rules, there are places that have names and populations. It is this that I am calling settlement hierarchy. Of course, often the named places and legal boundaries line up. > Fort Montgomery is one of these.

If such a relation is described on the Wiki, my > Google-fu is failing me. I heard about such relations long ago, but I have not really dealt with them. Around me there are nodes from the GNIS "populated places" dataset. But: https://wiki.openstreetmap.org/wiki/Relation:boundary and perhaps https://wiki.openstreetmap.org/wiki/Talk:Relations/Proposed/add_admin_centre_in_Relation:boundary This is messy, because there is the administrative center and then there is the place that most would consider the point that typifies the place. For New York, the epicenter of newyork-ness is arguably not Albany, but perhaps Penn Station in Manhattan. For small towns, people would almost certainly tag the place that everyone thinks of as the town center. In mine, it's where we have our original traffic light, common, town hall, and church. We have a new town office building, which happens to be in the same cluster, but in some towns it might be amile away. But still, that's just the town office location, not the town center. So I think we probably need a new relation member in addition to admin_centre which is just "centre", meaning a node which is the human-geography center of the administrative unit. That leaves place=locality and other things on nodes, since those sorts of settlement terms tend not to have boundaries.
