qualified primary source not properly converted from rdf, as illustrated by:

Hm, is it not? The result from importing/exporting is slightly different in structure - i.e.:

http://www.gutenberg.org/ebooks/996 prov:qualifiedDerivation :node17e9v6qb3x1 . :node17e9v6qb3x1 a prov:Derivation ; prov:entity ns1:XX2197892 . _:node17e9v6qb3x1 prov:type "prov:PrimarySource"^^xsd:QName .

But doesn't that correspond to a hadPrimarySource ns1:XX2197892? Should there be a method that checks if the Derivation has >1 property, and creates a binary hadPrimarySource if not?

are you saying the problem is in the converter?

I'm not sure it's an issue as such - at least, assuming:

ex:a prov:qualifiedDerivation _:n1

_:n1 a prov:Derivation; prov:entity ex:b; prov:type "prov:PrimarySource"^^xsd:QName.

Conveys the same as:

ex:a prov:hadPrimarySource ex:b ?

OK, translation is good, I believe. Issue solved!
