R1: For creator, contributor, and publisher provide support for management of (a) affiliation, (b) character portrayal (contributor only?), and (c) additional roles.

[pdpinch]

a. Allow association of creators, contributor, or publishers with affiliated organizations (stations, companies, etc).

b. PBCore does not specifically address character portrayal in the contributor elements. For instance for a Sesame Street segment, PBCore can state Henson, JimActor but does not provide a specific means to clarify whether Jim Henson is portraying Ernie or Kermit.

c. PBCore limits expression of roles to one per creator, contributor, or publisher, although frequently one creator, contributor, or publisher performs more than one role to avoid entering a contributor multiple times to state all of their roles."
