The following rules are relevant to what happens with annotation  
properties in OWL-RL

T(?p1, rdfs:subPropertyOf, ?p2), T(?x, ?p1, ?y)
=> T(?x, ?p2, ?y)
T(?p, rdfs:domain, ?c),  T(?x, ?p, ?y)	
=> T(?x, rdf:type, ?c)
T(?p, rdfs:range, ?c), T(?x, ?p, ?y)
=> T(?y, rdf:type, ?c)
T(?p1, owl:equivalentProperty, ?p2), T(?x, ?p1, ?y)
=> T(?x, ?p2, ?y)
T(?p1, owl:equivalentProperty, ?p2), T(?x, ?p2, ?y)
=> T(?x, ?p1, ?y)
T(?p1, rdfs:subPropertyOf, ?p2), T(?p2, rdfs:subPropertyOf, ?p3)	
=> T(?p1, rdfs:subPropertyOf, ?p3)
T(?p1, owl:equivalentProperty, ?p2)
=> T(?p1, rdfs:subPropertyOf, ?p2), T(?p2, rdfs:subPropertyOf, ?p1)

Here are some consequences of these rules.

If someone using OWL-RL writes the RDF equivalent of

PropertyDomain(p c)
EntityAnnotation(x Annotation(p y))

then the the rule application will add

ClassAssertion(c x)

If we have
and the triple
p rdfs:subPropertyOf p1

Then the rdf equivalent of
EntityAnnotation(x Annotation(p1 y))

Will be added.
