Project license not clear

[btschwertfeger]

The project defines the BSD license in its project.license.text and a license classifier License :: OSI Approved :: BSD License in project.classifiers.

1. The use of the license classifier is deprecated as of PEP 639
2. The project.license.text is deprecated as well (see PEP 639) which is no big deal as there is no deadline when it will be unsupported.
3. Both of the license declarations do not specify which license is actually used. There are many different BSD licenses out there. For users like us that process such metadata to be compliant with certain regulations, it would be nice if this project would specify a proper SPDX license (see https://spdx.org/licenses/). Either as project.license or via the License Expression field introduced in PEP 639.

The https://github.com/bbangert/beaker/blob/master/LICENSE file is a BSD-3-Clause, that is meant to be the single source of truth if you need license details

[btschwertfeger]

Automated systems read the project metadata by their keys and values. The License metadata field is not specific enough to interpret the actual license since it does not define a version like BSD-3-Clause nor uses it a LicenseRef-style license (https://spdx.github.io/spdx-spec/v2.3/SPDX-license-expressions/) indicating that the license provided does not matches any of the ones published here https://spdx.org/licenses/. The same counts for the deprecated classifier.

While the license file serves its purpose, in practice, it is not feasible or meant to be interpreted by non AI-systems.
