Abstract

   ISO/IEC 19770-2:2015 Software Identification (SWID) tags provide an
   extensible XML-based structure to identify and describe individual
   software components, patches, and installation bundles.  SWID tag
   representations can be too large for devices with network and storage
   constraints.  This document defines a concise representation of SWID
   tags: Concise SWID (CoSWID) tags.  CoSWID supports a similar set of
   semantics and features as SWID tags, as well as new semantics that
   allow CoSWIDs to describe additional types of information, all in a
   more memory efficient format.
