Software Identification (SWID) Tag Standard

An Introduction to the Standard

The Standard’s Development Team

ISO/IEC standards are created by dedicated volunteers. We thank the team of volunteers who tirelessly contributed to the development of this standard, and the organizations that supported their efforts.

In October 2009, an WG21 Interim meeting passed a resolution recognizing the efforts of the ISO/IEC WG21. Since then ISO/IEC WG21 has updated 19770-2 in 2015 and completed 19770-3 in 2016.

Obtaining the ISO/IEC 19770-2:2015 Software Identification Tag Standard

Copies of the standard are available for purchase at the following sites:

The standard can also be purchased from your local national standards body.

The 2015 schema (XSD) for XML documents used as software identification tags is available here.

A note for implementers – The 19770-2:2015 is compliant with the latest version of the standard, but does have deficiencies which are addressed in the draft “current” schema.  The
“current” version is available here as a reference for those interested in changes made subsequent to publishing the spec, and which might need to be considered by tag creation or processing tools.

The National Institute of Standards (NIST) has produced a helpful guide to understanding and implementing SWID tags.  Based on the 2015 version of the standard, NISTIR 8606, “Guidelines for the Creation of Interoperable Software Identification (SWID) Tags” is available here as a free download.

Revision to ISO/IEC 19770-2

The first version of the SWID tag standard was published in 2009. The revision to the standard was published in 2015.  Further work in support of the 2015 revision has been done by NIST with the publication of NIST-IR 8060 which defines end-user interoperability expectations for SWID tags. has also published the SWID Tag Signing Guidelines which enable publishers and users of SWID tags to know that the data in the tags have not been modified.
