Re: About the root element of the SKOS/RDF

Hi,

Depends on what you mean with "root node". It might be the Concept 
Scheme instance, it might be the set of broadest concepts, possibly 
the c_3397 and c_32543 in your piece of code below. Note that the 
Guide [1] recommends/prescribes (?) to use skos:hasTopConcept between 
the ConceptScheme node and the "root concepts", which should make it 
easy to query for the set of broadest concepts.

CHeers,
Mark.
