The pink area's legend may use the words "Conceptualizations (SKOS concepts)" or "Conceptualizations (@conceptScheme)" because SKOS itself does not conceptualize. --MZ

Why is "US Presidents" a subclass of foaf:Person? Seem like "US Presidents" should be a foaf:Group and "Ronald Regan" a foaf:Person who is a foaf:member of the foaf:Group "US Presidents".

The class "US Presidents" should be called "US President" to have consistent number. Every US President is a Person, hence a subclass of Person.

Michael - I agree; the plural was a mistake. I'm suprised how much discussion this quick scribbled diagram has generated, and entertained to be be having it on Flickr.
Regarding relationship between Group and Person, there has been a bit of discussion lately about using OWL2 punning to allow a Group to also be seen as a subclass of Person. This might allow for the idiom where a Group has worldly characteristics, like a chairperson or logo or hometown; but also for groups that are defined by membership criteria a la OWL. Bit of a hack though...
