       Resource-Oriented Lightweight Information Exchange (ROLIE)

Abstract

   This document defines a resource-oriented approach for security
   automation information publication, discovery, and sharing.  Using
   this approach, producers may publish, share, and exchange
   representations of software descriptors, security incidents, attack
   indicators, software vulnerabilities, configuration checklists, and
   other security automation information as web-addressable resources.
   Furthermore, consumers and other stakeholders may access and search
   this security information as needed, establishing a rapid and
   on-demand information exchange network for restricted internal use or
   public access repositories.  This specification extends the Atom
   Publishing Protocol and Atom Syndication Format to transport and
   share security automation resource representations.
