Hi, there is no clear resolution to merge these requirements: R-25-OBJECT-PROPERTY-DOMAIN (http://lelystad.informatik.uni-mannheim.de/rdf-validation/?q=R-25-OBJECT-PROPERTY-DOMAIN) R-26-DATA-PROPERTY-DOMAIN (http://lelystad.informatik.uni-mannheim.de/rdf-validation/?q=R-26-DATA-PROPERTY-DOMAIN) I would merge them to 'R-25-PROPERTY-DOMAIN' Cheers, Thomas -- Thomas Bosch, M.Sc.
