Concise Software Identification Tags
draft-ietf-sacm-coswid-11
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 the same features
as SWID tags, as well as additional semantics that allow CoSWIDs to
describe additional types of information, all in a more memory
efficient format.
