<p>Well, I think there are two different points in here, which need to be treated separately. Firstly how to represent the relationship between dependent states and their "parents", and secondly how to link the capital to the territory it is the capital of. In both cases I think the boundary relations are the place to put this information. For example Gibraltar's admin_level=2 relation can have a tag "dependent_on=GBR" (or something similar), and possibly "designation=dependent_territory". Alternatively, the UK relation could have Gibraltar as a member with a role of "dependent_territory", although this would meet the same controversy as the "subarea" roles which denote a hierarchical relationship of a local authority with its higher level LA (recursive relationships).</p>
<p>London could be included in both the England relation and the UK relation with the "capital" role, although that would be redundant as it is coincident with the admin_centre anyway.</p>

Like that a city can<br /> easily be capital of multiple administrative units (it might be a national<br /> capital and a provincial capital at the same time) and it stays distinct<br /> from the administrative centre.<br /><br /> A city cannot simply be a "capital" based on its own characteristics like<br /> population or area. Being a capital is a role of a place in the context of a<br /> territory, so putting this on the relation for the territory seems the most<br /> logical place to me.<br /><br /> As the capital and administrative centre are mostly coincident, I would<br /> suggest that adding the "capital" role would only be required for the<br /> exceptional cases. If no capital is specified explicitly, I would assume<br /> that the admin_centre also has that role.<br /><br /> //colin</blockquote>
