We have implemented one-to-many mapping between two ontologies by using a
third ontology, an Articulation [1]. It uses a Match class with multi-valued
subject and objects, for example:

<art:Match rdf:ID='M1'>
	<subject rdf:reference = &o1;name>
	<object rdf:reference = &o2;first_name>
	<object rdf:reference = &o2;last_name>
</art:Match>

A separate articulation ontology is used to provide a stand alone mapping
that avoids adding facts to either source ontology.

There is a prototype matching engine on our web site at [2]. It currently
uses DAML+OIL, but our plan is to convert it to OWL when the standard begins
to be stable.
