FWIW, REST based Web services already support this.  Of course, all
objects expose the same interface, so a "inheritance" relationship like
you describe is not a statement about interface, but about
implementation instead.

RDF Schema provides the means for expressing this sort of relationship.
For example;

<http://example.org/animal/cat/> rdfs:subClassOf <http://example.org/animal/>
<http://example.org/animal/dog/> rdfs:subClassOf <http://example.org/animal/>
<http://www.markbaker.ca/2001/02/Glory/> a <http://example.org/animals/dog/>
