Ah, interesting. Thanks.

The "foo is a subject of bar" interpretation sounds odd for anything  
except documents. "Buildings is a subject of the Eiffel Tower"  
doesn't really work either.

I wish there was a skos:in_category ...

I think for now I will just ignore these concerns and go ahead using  
skos:subject. Thus, if a biography of Wittgenstein has been  
categorized under "Philosophy", then I will categorize the guy  
himself under the same label.

Unless someone tells me right now that this will kill kittens.
