License not SPDX-compliant

[btschwertfeger]

The project declares the following license:

python-sortedcontainers/pyproject.toml

Line 13 in 3ac3586

license = {"text" = "Apache 2.0"}

which is not SPDX-compliant (https://spdx.org/licenses/; Apache-2.0 would be the correct value). PEP 639-aware tooling that more and more relies on SPDX-compliant licenses in the project metadata stuggles with this particular package, since the license can't be matched against the defined set of SPDX licenses.

Additionally, the license classifier is deprecated (https://peps.python.org/pep-0639/#deprecate-license-classifiers):

python-sortedcontainers/pyproject.toml

Line 17 in 3ac3586

"License :: OSI Approved :: Apache Software License",

So I propose the following diff to sanitize the project metadata:

diff --git a/pyproject.toml b/pyproject.toml
index e135023..f17dd5e 100644
--- a/pyproject.toml
+++ b/pyproject.toml
@@ -10,11 +10,10 @@ authors = [
 ]
 readme = "README.rst"
 requires-python = ">=3.2"
-license = {"text" = "Apache 2.0"}
+license = "Apache-2.0"
 classifiers = [

     "Programming Language :: Python :: 3",

After applying this change, the metadata looks like:

❯ uv build -q .
❯ unzip -qo dist/sortedcontainers-2.4.0-py3-none-any.whl
❯ grep License sortedcontainers-2.4.0.dist-info/METADATA
