Re: Question regarding the Organization Ontology

I've done something similar to Bernard, except instead of using a new Position class, I simply add a "post" property to org:Membership. Instead of people holding posts directly, all people hold posts through their memberships; I therefore do not use the org:holds or org:heldBy properties. org:Membership already has org:memberDuring to express the time interval during which the membership exists, or in my case during which the post is held.

With respect to Christopher's affiliations, I add an "onBehalfOf" property to org:Membership, to express on whose behalf that person is a member.

I prefer to avoid a proliferation of sub-classes when an additional property would do.
