(Batch-)upload payload validation requires use of rdfs:label; skos:prefLabel is not sufficient #103
Description
Whilst testing the batch-upload capability with a (large) skos:Collection, I noticed that the payload validation was failing due to the lack of rdfs:label property for the embedded concepts. The skos:Collection did include skos:prefLabel properties which, as a sub-property of rdfs:label, should have been sufficient. However, the validation still failed.
(I worked around this by providing rdfs:label properties in addition to the skos:prefLabel properties - but this is clunky).
Please fix validation so that sub-properties of rdfs:label are seen as valid substitutions.
