If the CRM is interpreted as an OWL ontology, then the most general relationship between two objects is *owl:topObjectProperty. *
This property has very weak semantics (e.g. that there is some known relationship between a and b). One benefit / problem with using this property is that it is a super property of all object properties, so you may need to be careful to turn inference on / off. You can also define your own equivalent placeholder, which will make it easier to use inference when you can start upgrading to more specific relationships. Simon
