Importantly, the sentence you quoted ended with "... in some special cases," which was lost.

I would hope to see something like this more than 80-90% of the time initially and 100% of the time in the long run:

<http://example.org/work/johnnys-elephant> bf:label "Miller, Joel, 1912-. Johnny's Elephant";
	bf:title "Johnny's Elephant";
	bf:author <http://example.org/person/joe-miller>;
	bf:illustrator <http://example.org/person/joe-miller>;
	bf:language <http://id.loc.gov/vocabulary/languages/eng>;
	a bf:Book,
		bf:LanguageMaterial,
		bf:Work.

<http://example.org/work/joe-miller> bf:authority <http://id.loc.gov/authorities/names/miller-joe>;
	bf:label "Miller, Joseph, 1912-";
	a bf:Person.

Yours,
Kevin
