Most tools used for compliance and SBOM generation use SPDX identifiers This change brings us a step closer to an easy SBOM generation. define NuttX local NuttX-PublicDomain identifier “Public Domain” is a concept distinct from copyright licensing; it generally means that the work no longer has any copyright protection or ownership, and therefore requires no license permission in order to use, copy, modify, distribute, perform, display, etc. In the United States – and many jurisdictions – copyright protections attach automatically to creative works upon creation if they satisfy certain minimum criteria. “Public Domain” would thus represent a significant change to the legal status of the work. The rules around “Public Domain” often vary or are unspecified jurisdiction to jurisdiction. Adding to the confusion, some jurisdictions may not even recognize the concept of “Public Domain” (or similar). As such, a license may nevertheless be required or implied in these cases. Even in the U.S., there is no clear, officially-sanctioned procedure for affirmatively placing copyright-eligible works into the “Public Domain” aside from natural statutory expiration of copyright. The bottom-line is, there are few if any objective, brightline rules for proactively placing copyright-eligible works into the Public Domain that we can broadly rely on.
