Policies & Enforcement

• Object Policies– METS = Policy, FEDORA = Enforcement– Eg. Rights:

– FEDORA uses XACML (eXtensible Access Control Markup Language) to enforce rights on one or a group of objects within the repository. Rights are based on XACML statements constructed from the METS:Rights from METS document.

• Repository-Wide Policies– Every Object had METS– Every Object is linked to a MARC record– Every Object has DC (OAI/Internal Use)
