Richard: your advise was Ok! Thank you! I realized the RDFcrosswalk, its display in dwell as well its migration/display in sesame: very excellent!
However two issues still remain open to me: 1) instances of dc qualifiers are harvested as instances of the main dc term (ex. the qualifiers of dc:description; how to harvest them separately?); 2) the embedding of dwell in the dspace web ui (dspace run under tomcat, dwell not: how to manage this?)
