Concise Software Identifiers
draft-ietf-sacm-coswid-01
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.

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 instances.
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
integrity measurements (RIM) and security logs of measured
software components [I-D.birkholz-tuda].
SWID tags, as defined in ISO-19770-2:2015 [SWID], provide a
standardized format for a record that identifies and describes a
specific release of a software product. Different software products,
and even different releases of a particular software product, each
have a different SWID tag record associated with them. In addition
to defining the format of these records, ISO-19770-2:2015 defines
