SPDX 2.1.1 specification - final review by 2019/5/21

Kate Stewart

In 2017 the project decided to move the specification from google documents to github and a repository was set up at:

Before we could move forward though, we needed to make sure we weren't loosing content/introducing errors,  so the decision was made to create a 2.1.1 version of the specification, with no significant content changes (only bug fixes).

2.1.1 was initially made available at: in 2018 by Thomas Steenbergen, in a beautiful online format (Thank you!), much improved and useful for those accessing the specification online.   However we stalled out on being able to generate .pdf version to get a static copy of this version.

Thanks to Jack Manbeck's efforts in 2019,  we've finally got a .pdf version available to be reviewed and approved.   Once this version is approved, we can start to incorporate the 2.2 changes into the specification.

A final candidate pdf version of the SPDX 2.1.1 specification is attached to this document, please review and open an issue at if you see a regression compared to SPDX 2.1 content which is at: 

If there are no significant regressions found compared to 2.1 in the review window, we will log this as the 2.1.1 version and start to incorporate the 2.2 content and features that have been agreed on over the last year into the reference version of the specification on github.

The review window for the 2.1.1 candidate will end on 2019/5/20.

If you have any concerns,  please either open an issue at  (against 2.1.1 milestone) or join us on the spdx-tech call to discuss.
