yes it is :-)

I prefer a popular solution that can actually be used, over an "ideal" 
solution that is only relevant to some experts. FRBR was already 
blessed enough in 1998, so libraries had time enough for adption.
In the end, the adoption of FRBR is irrelevant. What's relevant is 
the solution of problems - FRBR in any of its forms is nothing but 
a tool for this.

good to know.

I don't contradict myself with the assertion, I just hijack Ians 
FRBR ontology URIs, assuming that most people are interested
in simple URIs but less in applying the disjointedness constraint. 
A better solution may be to create a fork and upvote it on
http://prefix.cc.
I will not hesitate to do so as soon as the ignored disjointedness
constraint becomes a problem.
