Someone's affiliation is a relationship of membership or belonging that the person can have with respect to a particular organization (i.e., an individual of the class `foaf:Organization`). 
Such an affiliation may be specified in the document with respect to which that agent is an author or contributor. 
A particular individual of [SCoRO](http://purl.org/spar/scoro), i.e., `scoro:affiliate` (belonging to the class `scoro:OrganizationalRole`) is used to express such an affiliation. 
The domain of `pro:withRole` is not `foaf:Agent`, but rather a member of the class `pro:RoleInTime`, which itself is the range of the property `pro:holdsRoleInTime`, for which the domain is `foaf:Agent` (i.e., our contributor).
        </vaem:rationale>
    <skos:note xml:lang="en">
The full minimum pattern to express the role of some agent is: 
        foaf:Agent 
                pro:holdsRoleInTime [ 
                        a pro:RoleInTime ; 
                        pro:withRole pro:Role 
                        ] . 
PRO permits one to specify the time period over which a role is held, and the other contextual entities to which that agent's role relates.
