Concise Software Identifiers
draft-ietf-sacm-coswid-02
Abstract
This document defines a concise representation of ISO 19770-2:2015
Software Identifiers (SWID tags) that is interoperable with the XML
schema definition of ISO 19770-2:2015 and augmented for application
in Constrained-Node Networks. Next to the inherent capability of
SWID tags to express arbitrary context information, CoSWID support
the definition of additional semantics via well-defined data
definitions incorporated by extension points.

1. Introduction
SWID tags have several use-applications including but not limited to:
o Software Inventory Management, a part of the Software Asset
Management [SAM] process, which requires an accurate list of
discernible deployed software components.
o Vulnerability Assessment, which requires a semantic link between
standardized vulnerability descriptions and IT-assets [X.1520].
o Remote Attestation, which requires a link between reference
