SACM Working Group H. Birkholz Internet-Draft Fraunhofer SIT Intended status: Standards Track J. Fitzgerald-McKay Expires: 26 August 2021 National Security Agency C. Schmidt The MITRE Corporation D. Waltermire NIST 22 February 2021 Concise Software Identification Tags draft-ietf-sacm-coswid-17 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.
