IMHO we don't even need a relation. All islands can have the same  tag
cluster:archipelago=*. If data consumers find a tag that starts with
"cluster:" they can group all elements that have the same
cluster:archipelago. It's the same as streets in a city. How do you know if
two segments of a street are the same street? They have the same name.

Archipelago isn't so much an entity in itself. It is just an attribute of
the islands it is consisted of.
