    rdfs:comment """E81-CIDOC - This class comprises the events that result in the simultaneous destruction of one E77Persistent Item and the creation of another E77 Persistent Item that preserves recognizable substance from the first but has a fundamentally different nature and identity. [...] Instances of E81 Transformation are therefore distinct from re-classifications (documented using E17 Type Assignment) or modifications (documented using E11 Modification) of objects that do not fundamentally change their nature or identity.
++Philosurfical : need some consideration here - cause it's a quite important class""" ;
