Others have mentioned the RELS-EXT datastream in a fedora object. Here's an example of two such datastreams in a simpler compound object (an ETD): One from the parent dissertation object (primarily descriptive) and one from a child object that stores a PDF of the dissertation itself. (Namespace declarations have been removed to improve readability.)
So you can see how this might play out with the model Steven M mentions. Though it's not the case here, the child object could belong to more than one parent object.
Parent RELS-EXT datastream:
<rdf:RDF>
<rdf:Description rdf:about="info:fedora/1711.dl:DRSBPUUNXGL2R8M">
<hasModel xmlns="info:fedora/fedora-system:def/model#" rdf:resource="info:fedora/1711.dl:CModelUWDCObject"/>

</rdf:Description>

Child RELS-EXT datastream (one of three):
<rdf:RDF>
<rdf:Description rdf:about="info:fedora/1711.dl:VOG6NUAUMIPBT9C">
<hasModel xmlns="info:fedora/fedora-system:def/model#" rdf:resource="info:fedora/1711.dl:CModelUWDCObject"/>
