jakob, I haven't yet had time to look at your SOBR, but I am meeting  
soon with some folks to talk about a kind of "RDA lite" -- the goal  
being to build up a data structure using RDA but starting with a bare  
skeleton rather than the whole 1,300 properties. (And I'm pretty sure  
it will not be the same as RDA core.) If we come up with anything  
concrete from this first meeting I will post it here and we can  
compare to your schema. This one will have the library catalog "bias"  
but that simply means that it may serve the library cataloging function.
