I have two OWL files each file describes what a receipt is, OWL-A has class named RecBody with property hasItem. OWL-B has the same class but has a property called hasField. both are identical

My question is how specify to the RDF engine that hasItem and hasField are the same "thing" I need a solution do this automatically since I face such problem when I try to bind data from heterogeneous sources

Well, you can use the owl:sameAs tag to do this, according to the Owl language reference. Using this tag will make it clear to a reasoner that these two constructs refer to the same thing.

For classes be sure to use owl:equivalentClass and not owl:sameAs as the latter if used on classes will make your ontology OWL-Full
