The domain of copyright:date is bf:Provider, so it should not be directly under Instance. It should only be in bf:publication.
This is another property that may be better as typed data. The notion of copyright is inherent in the property so the copyright symbol is unnecessary and the date should be typed instead of a literal.
bf:copyrightDate appears twice in converted records, once as a subproperty of Instance and again as a subproperty of bf:publication.
