Product Type not allowing top concepts

[RaggedStaff]

The connector is not allowing assignment of top concepts within Taxononies (specifically Product Type, may apply to other taxons).

Given the sparse nature of the DFC Taxonomies, I had assumed (and I think agreed with Florence) that we would default up to a level that worked. For example: a Plum tomato, would default up to "Tomato" as there is no subclass for Plum Tomatoes. or a Loquat would default to Fruit.

This is blocking OFN, as we can't use any level of Product Type but the narrowest one. Ie :

• we can't use Drink -> Soft Drink, modelled as a DataFoodConsortium::Connector::SKOSInstance in the connector
• we can only use the most specific one Drink -> Soft Drink -> Lemonade, modelled as a DataFoodConsortium::Connector::SKOSConcept in the connector

Ideally all levels of Product Type should be modelled as DataFoodConsortium::Connector::SKOSConcept. Also none of the SKOSConcept property are set: broaders, schemes, narrowers and prefLabels. This makes it really difficult to try and match OFN taxonomies with DFC Product Types, as there is no easy way to traverse the Product Type tree.
