Abstract
A portable access control list (PACL) model is provided. The PACL is not meant to represent an actual ACL instantiation, but rather a global representation of the access control list concept. A portable ACL entry includes a tuple of identifiers, permissions and/or actions, and application rules. The portable ACL model is a superset of all existing identifiers, permissions, and actions. The PACL model also is unordered; therefore, any ACL model may be represented in the PACL model. A programming model is also provided. The programming model consists of common operations performed on ACL objects and may accept PACL entry information or filesystem specific ACL entry information. A mechanism is provided for performing conversion operations between actual filesystem specific ACL models and the PACL model. The PACL model may serve as an intermediate model between disparate filesystems.
