The metadata intentds to follow the semantics of the Dublin Core:

  http://www.dublincore.org/dces

About the 'Rights' element, that spec says:

    Name:       Rights Management

    Identifier: Rights

    Definition: Information about rights held in and over the resource.

    Comment:    Typically, a Rights element will contain a rights
                management statement for the resource, or reference
                a service providing such information. Rights information
                often encompasses Intellectual Property Rights (IPR),
                Copyright, and various Property Rights.

                If the Rights element is absent, no assumptions can be made
                about the status of these and other rights with respect to
                the resource.

For instance, I foresee having "Copyright (c) 2001 Digital Creations"
show up in the Rights field of "official" documentation. I think that
Zope's own security mechanisms are a better match
for what you want.
