Abstract

Fractional permissions allow resource tracking type systems to give out multiple read accesses to the same resource without losing the ability to re-form a unique write access later. This paper describes the motivation for fractional permissions, and different fractional models including those for which fractional scaling is required. We describe a particular system of fractional permissions that uses scaling to support the technique of "nesting."
