Abstract
Entitlements to resources can be determined by using access rules that are organized as respective ranges in an entitlement space. An access rule can represent a range between two rational numbers in the entitlement space; the range can be represented by a single rational number. Due to the way the rational numbers are chosen, a child rule is completely covered by its parent, and a parent has remaining room in the entitlement space for unlimited additional children. Entitlement checking for a large batch of resources can be performed quickly based on reusing calculated permitted ranges in the entitlement space. Implied permissions can be supported. Content can easily be added, and the access rules can be modified without unduly impacting the underlying tree structure, if at all.
