Abstract
This document extends the Resource-Oriented Lightweight Information

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.
