Forgot to paste this into my prior response .

Here's why its OK:

1. 
http://linkeddata.uriburner.com/describe/?url=http%3A%2F%2Fdata.bnf.fr%2Fark%3A%2F12148%2Fcb14521343b 
-- new URI

2. 
http://linkeddata.uriburner.com/describe/?url=http%3A%2F%2Fstitch.cs.vu.nl%2Fvocabularies%2Frameau%2Fark%3A%2F12148%2Fcb14521343b 
-- old (prototype) URI

3. 
http://linkeddata.uriburner.com/describe/?url=http%3A%2F%2Fdata.bnf.fr%2Fark%3A%2F12148%2Fcb14521343b&sas=yes 
-- new URI and effects of enabling owl:sameAs inference .
