Hi Simon, The Core guide reads > To assert that one concept is broader in meaning (i.e. more general) > than another, where the scope (meaning) of one falls completely within > the scope of the other, use the |skos:broader > <http://www.w3.org/2004/02/skos/core/spec/#broader>| property The current Primer reads the same, as well as the Reference. I think this is rather compatible with ISO 2788 for instance.
