A computer-implemented mechanism for granting rights is described. A license may be used to identify one or more principals, resources, rights and conditions. The license also identifies a license format scheme and a license format modification scheme. An access control module or other entity may interpret the license in accordance with the license format scheme and license format modification scheme.

Substitution groups/inheritance for extensibility in authorization policy

A computer-implemented mechanism for granting rights to a resource is described. A license identifies one or more principals, resources, rights and conditions in fields of the license. The license fields include one or more instances of one or more variables. The variables are universally quantified so that each variable may be any one of a set of values. All instances of any given variable are bound to the same value.

Digital licenses that include universally quantified variables

A computer-implemented mechanism for comparing information sets is described. The mechanism may include a comparison system that concentrates on the schema in each information set. An alternative embodiment includes an equality comparison mechanism that performs sets of initial comparisons to determine whether the information sets are inherently different and not needing a detailed comparison using the schema-centric comparison technique.
