I saw there was some error in the example on slide 5 of
http://esw.w3.org/topic/Rdb2RdfXG?action=AttachFile&do=view&target=RIF4RDB2RDF.pdf
Here an improved version (also uploaded at the same address):
slide 5 uses the iri-string predicate. that is already a nasty
example... assume, for a mapping from your RDB to RIF, you have the rule:
Forall ?P ( ?P#foaf:Person[foaf:phone -> ?T] ) :-
And (
mydb:Customers( ?ID ?Name ?Phone ?Address)
External( pred:iri-string( ?P External( func:concat(
"http://mydb.org/Persons/" ?ID )))
External( pred:iri-string( ?T External( func:concat( "tel:" ?Phone )))
)
)
