RDFS is useful, but does not solve all possible
requirements
-
Complex applications may want more possibilities:
-
- characterization of properties (not only listing their range
and domain)
- identification of objects with different URI-s
- disjointness or equivalence of classes
- construct classes, not only name them
- more complex classification schemes
- can a program reason about some terms? E.g.:
-
- “if «Person» resources «A» and «B» have the same
«foaf:email» property, then «A» and «B» are identical”
- etc.
