TransformerCLI: CPC classes should have one Main and multiple Further types #73

Closed legolego closed 5 years ago

legolego commented 5 years ago

Hi, Looking at the CPC classes in the transformed JSON files, all of the CPC classes have a type main. I think there's one, but not sure if always true. The rest of the CPC classes should be of type further. These are for patent number US9428405B2 (source XML attached).

Result JSON:
