Abstract

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