 It is conventional to map a relation name to a relational extension directly.  This however presumes that the vocabulary is segregated into relation names and individual names, and RDF makes no such assumption. Moreover, RDF allows an IRI to be used as a relation name applied to itself as an argument. Such self-application structures are used in RDFS, for example. The use of the IEXT mapping to distinguish the relation as an object from its relational extension accommodates both of these requirements. It also provides for a more intuitive notion of RDFS 'class' which can be distinguished from its set-theoretic extension.
