A Usage for Shared Resources in RELOAD (ShaRe)
Abstract
This document defines a REsource LOcation And Discovery (RELOAD)
Usage for managing shared write access to RELOAD Resources. Shared
Resources in RELOAD (ShaRe) form a basic primitive for enabling
various coordination and notification schemes among distributed
peers. Access in ShaRe is controlled by a hierarchical trust
delegation scheme maintained within an access list. A new
USER-CHAIN-ACL access policy allows authorized peers to write a
Shared Resource without owning its corresponding certificate. This
specification also adds mechanisms to store Resources with a variable
name that is useful whenever peer-independent rendezvous processes
are required.
