Oberallgäu is currently mapped as a political (not an administrative) boundary, so Sonthofen would be neither a capital, nor an administrative center of any relation. Correctly, its node has no capital=* or admin_level=* tags.
Swabia, on the other hand, has its government seat in Augsburg, and its node currently has no capital=* nor admin_level=* tags. Government seat is not the same thing as a capital (as pointed out earlier), so it seems correctly mapped too. Bavaria, a state (admin_level=4), has it's capital Munich's node tagged with capital=4, which seems to agree with the rule of tagging the capital city as capital=[lowest admin level of all regions that have it as capital]. If it were Germany's capital (as is Berlin), the node would be tagged as capital=2 by this pattern. However, capital=* and state_capital=* would also work to describe this particular situation because government seat is not the same thing as a capital (they often are the same city, but not always). So, for the sake of clarity, I think it would be acceptable if we agreed that: - we place capital=* on actual capitals (not any admin_centre), since using numbers is more flexible than capital=yes and state_capital=yes (equivalent to capital=2 and capital=4) - what the admin_centre role refers to is a government seat, and in some rare situations there may be more than one - we define a "capital" role in administrative boundary relations for those rare cases where capital and government seat are different cities Also it seems that rendering programs are more concerned with the concept of "capital" than "government seat", so it shouldn't be necessary (at least not yet) to arrange another tag for nodes (such as the capital tag) to identify them. By this reasoning, Berlin's node would be tagged as capital=2 (as would any country capital). And perhaps some rendering programs out there (Mapnik/Carto, osmarender, and others) would need to be tweaked to support this value. Well, this is me thinking about all per country variations. In Brazil, we would end up only using capital=2 for Brasília and capital=4 for all state capitals. If capital=2 is not yet supported by apps, then maybe we could copy Berlin temporarily (capital=yes+admin_level=2), but at least knowing what the future tagging goal is. (We can just leave a note on the node explaining that.)
