== SPDX Tags in the tree
The project uses https://spdx.dev[SPDX] tags in our source base.
-At present, these tags are indented to help automated tools reconstruct license requirements mechanically.
-All _SPDX-License-Identifier_ tags in the tree should be considered to be informative.
-All files in the FreeBSD source tree with these tags also have a copy of the license which governs use of that file.
-In the event of a discrepancy, the verbatim license is controlling.
-The project tries to follow the https://spdx.github.io/spdx-spec/v2.2.2/[SPDX Specification, Version 2.2].
-How to mark source files and valid algebraic expressions are found in https://spdx.github.io/spdx-spec/v2.2.2/SPDX-license-expressions/[Annex D] and https://spdx.github.io/spdx-spec/v2.2.2/using-SPDX-short-identifiers-in-source-files/[Annex E].
-The project draws identifiers from SPDX's list of valid https://spdx.org/licenses/[short license identifiers].
-The project uses only the _SPDX-License-Identifier_ tag.
-
-As of March 2021, approximately 25,000 out of 90,000 files in the tree have been marked.
+SPDX-only license marking (without reproducing the full license text) is strongly preferred for new files.
+When a file contains only a copyright notice and an SPDX-License-Identifier tag, the SPDX tag specifies the license for that file.
+When a file contains both an SPDX-License-Identifier tag and the full verbatim license text, the SPDX tag is informative and the verbatim license is controlling in the event of a discrepancy.

= Software License Policy
+The canonical FreeBSD license policy, including preferred license templates, acceptable licenses, and SPDX usage, is documented in the link:{license-guide}[FreeBSD License Policies] article.
+
+What follows is a summary of the key points.
+
== Philosophy
The FreeBSD Project aims to produce a complete, BSD-licensed operating system allowing consumers of the system to produce derivative products without constraint or further license obligations.
@@ -20,142 +26,16 @@
We instead encourage FreeBSD and third party developers to seek the relicensing or reimplementation of critical components under the BSD license.
Such would ease their more integral adoption into the FreeBSD operating system.
-== Policy
-
-* The import of new software licensed under any licenses other than the BSD license and BSD-Like Licenses (as defined below) requires the prior approval of the FreeBSD Core Team. Requests for import must include:
-** A list of features or bug fixes that the new version or patches contain, along with evidence that our users need those features. PRs or references to mailing list discussions are ideal forms of evidence.
-** A list of FreeBSD branches that may be affected. Expansions of scope require a new request to and approval from the FreeBSD Core Team.
-
-* The Apache License 2.0 is acceptable for use in some cases. The Core Team must approve the import of new Apache License licensed components or the change of license of existing components to the Apache License.
-** This license is approved for the following components:
-*** LLVM toolchain and (with LLVM Exceptions) runtime components.
-*** Subversion and its dependencies
-
-* The BSD+Patent License is acceptable for use in some cases. The Core Team must approve the import of new BSD+Patent License licensed components or the change of license of existing components to the BSD+Patent License.
-** This license is approved for the following components:
-*** EDK2 derived code related to UEFI functionality
-
-* The Common Development and Distribution License (CDDL) is acceptable for use in some cases. The Core Team must approve the import of new CDDL licensed components or the change of license of existing components to the CDDL.
-** This license is approved for the following components:
-*** DTrace
-*** ZFS filesystem including kernel support and userland utilities
-
-* Historically, the phrase 'All Rights Reserved.' was included in all copyright notices. The BSD releases had it to comply with the Buenos Aires Convention of 1910 in the Americas. With the ratification of the Berne Convention in 2000, it became obsolete. As such, the FreeBSD project recommends that new code omit the phrase and encourages existing copyright holders to remove it. In 2018, the project updated its templates to remove it.
-
-=== Acceptable licenses
-
-The following licenses are considered to be acceptable BSD-Like Licenses for the purpose of this Policy. They must be reproduced verbatim on any new code. Deviations or the use of any other license must be approved by the FreeBSD Core Team:

+* SPDX-only license marking is strongly preferred for new files.
+The preferred order is the copyright notice first, followed by the SPDX-License-Identifier, but either order is acceptable.
+New contributions to FreeBSD should use the BSD-2-Clause license.
+* The import of new software licensed under any licenses other than the BSD license and BSD-Like Licenses requires the prior approval of the FreeBSD Core Team.
+* The Apache License 2.0, BSD+Patent License, and Common Development and Distribution License (CDDL) are acceptable for use in some cases with Core Team approval.
+See the link:{license-guide}[full policy] for approved components and details.
+* Code under some non-BSD licenses must be placed in specific sections of the repository, and in some cases, compilation must be conditional or disabled by default.
+* The FreeBSD project discourages completely new licenses and variations on the standard licenses.
+New licenses require the approval of the FreeBSD Core Team.
-* It is acceptable to use only the SPDX-License-Identifier
-** See https://spdx.github.io/spdx-spec/[Annex D of SPDX Standard] for definition of standard SPDX-License-Identifier expressions used, how to interpret them and where to find the license text(s) that are applicable.
+For the complete policy including license templates, acceptable license list, and SPDX expression syntax, see the link:{license-guide}[FreeBSD License Policies] article.
