Subject: [Buildroot] [PATCH 6/7] package/pkg-python: support PURL generation
Date: Tue, 15 Apr 2025 21:55:40 +0200	[thread overview]
Message-ID: <20250415195547.199428-8-thomas.perale@mind.be> (raw)
In-Reply-To: <20250415195547.199428-1-thomas.perale@mind.be>

The PURL specification for python packages follows the coordinates from
the sonatype ossindex:

https://ossindex.sonatype.org/ecosystem/pypi

- The PURL type is 'pypi'.
- The PURL name is the package name. Since buildroot python packages
  include a 'python-' prefix to the name of package, this part is
  stripped.
