Description

I have marked a media file with the CC-PDM-1.0 license and the lint command is outputting the following:

$ reuse lint
reuse.project - WARNING - Could not resolve SPDX License Identifier of LICENSES/CC-PDM-1.0.txt, resolving to CC-PDM-1.0. Make sure the license is in the license list found at <https://spdx.org/licenses/> or that it starts with 'LicenseRef-', and that it has a file extension.
# BAD LICENSES

'CC-PDM-1.0' found in:
* LICENSES/CC-PDM-1.0.txt
* doc/bmbf_en.jpg


# SUMMARY

* Bad licenses: CC-PDM-1.0
* Deprecated licenses: 0
* Licenses without file extension: 0
* Missing licenses: 0
* Unused licenses: 0
* Used licenses: CC-BY-SA-4.0, LGPL-2.1-or-later, MPL-2.0, CC-PDM-1.0, Apache-2.0, MIT
* Read errors: 0
* Files with copyright information: 121 / 121
* Files with license information: 121 / 121

Unfortunately, your project is not compliant with version 3.3 of the REUSE Specification :-(


# RECOMMENDATIONS

* Fix bad licenses: At least one license in the LICENSES directory and/or
  provided by 'SPDX-License-Identifier' tags is invalid. They are either not
  valid SPDX License Identifiers or do not start with 'LicenseRef-'. FAQ about
  custom licenses: https://reuse.software/faq/#custom-license

The tool was able to download the license from https://github.com/spdx/license-list-data/blob/main/text/CC-PDM-1.0.txt and is listed on the SPDX website here: https://spdx.org/licenses/CC-PDM-1.0.html.

I see that the CC-PDDC license is listed as a supported license with reuse supported-licenses, however, I do not see it listed on the Creative Commons website so I am assuming CC-PDDC is a deprecated license.

This bug is blocking https://codeberg.org/libobscura/libobscura/pulls/18.

Steps to Reproduce

1. Download and install the 5.0.2 REUSE tool.
2. Create a project and add any kind of file.
3. Specify the license of the file with the following header (or .license file) information:

   SPDX-FileCopyrightText: NONE
   
   SPDX-License-Identifier: CC-PDM-1.0
   

4. Run reuse lint.

It seems CC-PDM-1.0 was added to the license-list-data after the 5.0.2 REUSE tool release.

Solution to fix the bug

The licenses.json file needs to be updated from 3.25.0 to 3.26.0 to support CC-PDM-1.0, among other license additions/changes.
