The first order formalization given in the crm document are: P14(x,y,z) ⊃ [P14(x,y) ∧ E55(z)]
Note that the predicate on the left hand side has three arguments, which is more arguments than rdf is comfortable with. The "in the role of" property is modifying an instance of a "carried out by" property. An activity can be carried out by several different agents, each in a different role, so the property cannot be attached directly to the activity. There are several possible ways of representing this using semantic web tools. The first approach is to use RDF reification. I am not going to say anything more about this. If you are using OWL 2, you can add an annotation each "carried out by" property assertion. This is not ideal, as annotations are not really supposed to be part of the data in the model, and most reasoners ignore them. They are also not easy to work with in RDF. A third approach is to define your own class for reification, representing an instance of a "carrying out" ; this class would have properties relating the activity, the agent, and the role. The best approach may be to define a sub property of P14 for each type of carrying out in a role which is relevant to your model. You can specify the role associated with all uses of this property using a property whose subject is the subproperty.
