                   draft-banghart-mile-rolie-csirt-01

Abstract

   This document extends the Resource-Oriented Lightweight Information
   Exchange (ROLIE) core to add the information type categories and
   related requirements needed to support Computer Security Incident
   Response Team (CSIRT) use cases.  The indicator and incident
   information types are defined as ROLIE extensions.  Additional
   supporting requirements are also defined that describe the use of
   specific formats and link relations pertaining to the new information
   types.
