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
