GregorHagedorn - Wed May 10 2006 - Version 1.5 Parent topic: EnumeratedValues Provides codes for roles like author, editor, photographer, advisor, or copyright holder. This type is implemented as a union of all AgentRole* enumerations. It is provided for programming convenience and not currently used in schema. The roles and their codes used here are based on http://www.loc.gov/marc.relators/ (as of 2004/6 available at http://dublincore.org/usage/meetings/2004/03/Relator-codes.html). For example, the enumerated code "aut" for author corresponds to http://www.loc.gov/marc.relators/aut. The DublinCore Agents group is considering using the same codes (see e. g. http://www.loc.gov/marc/dc/Agent-roles.html), but as of 2004/6 the DublinCore Agents subgroup did not yet agree on a Creator/Contributor refinement as qualified DublinCore. Note that the roles selected here are a subset of the MARC roles.
The following role subsets are defined:
AgentCreatorRoleEnum: Enumeration of roles supported for creator agents.
AgentContributorRoleEnum: Enumeration of supported roles for contributor agents.
AgentOwnerRoleEnum: Enumeration of supported roles for owner/copyright agents.
(An additional intermediate AgentCreatorContribRoleEnum is defined as the union of creator and contributor roles (AgentCreatorRoleEnum and AgentContributorRoleEnum), for types where this distinction is not intended, but owner roles (AgentOwnerRoleEnum) shall be excluded.)
Enumeration of supported roles for owner/copyright agents. See AgentRoleEnum for information about the MARC relator codes.
Without changing the enumeration lists and semantics, a technical problem with Xerxes was resolved in newer versions of UBIF, see AgentRoleEnumXerces262Problem. -- Gregor Hagedorn - 12 Sept 2004
