Display SKOS vocabularies regardless of their structure (skos:broader or skos:narrower)

[galviset]

Hi,
SKOS vocabularies currently need at least one skos:ConceptScheme to be displayed in the UI, and hierarchy works only if skos:broader is used. While I agree the former should be used at least once when defining a vocabulary, there are instances where it's not the case, such as NVS vocabularies (https://vocab.nerc.ac.uk/) we re-distribute through the EarthPortal (example: https://earthportal.eu/ontologies/NVS_L05 with its original source https://vocab.nerc.ac.uk/collection/L05/current/) . Concerning the latter, skos:narrower being the opposite of skos:broader, I think it's logic both can contribute to build the hierarchy.
A possible way to define the root of the structure when there are no skos:ConceptScheme is to let the user define it (e.g. using the URI metadata field, or a brand new field).

Thanks
This issue is well known to us and we shall address it yes.
@syphax-bouazzouni Can you point here the other issues related to SKOS support in AgroPortal so that we can specify and address this point.

@galviset . Do you confirm original L05 contains a skso:ConceptScheme so we do not conflict with the other issue of dealing primarliy with collection?

Hi both and thanks for the opening of this issue.
L05 originally does not contain skos:ConceptScheme.
