source source Derived from Derived from a different resource. Derivation conserns itself with derived knowledge. If this resource has the same content as the other resource, but has simply been transcribed to fit a different model (like XML -> RDF or SQL -> CVS), use pav:importedFrom. If a resource was simply retrieved, use pav:retrievedFrom. If the content has however been further refined or modified, pav:derivedFrom should be used. Details about who performed the derivation (e.g. who did the refining or modifications) may be indicated with pav:contributedBy and its subproperties.
