License and Attribution of the Pytest Logo?

[hwhsu1231]

Hello, Pytest Team,

I'm the author of the @localizethedocs organization, which focuses on creating l10n projects for open-source project documentation. For example:

• localizethedocs/cmake-docs-l10n
• localizethedocs/conan-docs-l10n
• localizethedocs/ros2-docs-l10n
• and more.

Currently, the pytest-docs-l10n project is in the incubation phase. To place the Pytest logo at the top of the README, I need to upload the logo to the static repository and then access it via jsDelivr. Here is the SVG logo I found:

https://github.com/pytest-dev/design/blob/43bbb9b7c2fd484a60c6922b903ca76796b3f45b/pytest_logo/pytest_logo_notext.svg

However, I would like to confirm the license of the logo and what attribution is required.

First, based on the wikimedia, the license of the Pytest logo is CC BY 2.5. However, the LICENSE file is CC BY-SA 4.0. How should the License part in the Attribution be written?

Next, based on the wikimedia, the author of the Pytest logo is Holger Krekel. However, the AUTHORS file displays 4 people: Florian Bruhin, Floris Bruynooghe, Brianna Laugher, and Vasily Kuznetsov. How should the Author part in the Attribution be written?

i don't recall how this was solved back in 2009 - i suspect @hpk42 is the only one who might remember

as for license versions the wikipedia upload was around 2009 when the version 2.5 was the latest of the license available
it has been updated since

i'd recommend presuming CC BY-SA 4.0 matches (IANAL)

How about the following attribution?

Code:

<tr>
  <td><code>mark/pytest.svg</code></td>
  <td><img src="mark/pytest.svg" alt="pytest" width="100"/></td>
  <td><a href="https://github.com/pytest-dev/design/blob/43bbb9b7c2fd484a60c6922b903ca76796b3f45b/pytest_logo/pytest_logo_notext.svg">Link</a></td>
  <td>By <a href="https://pytest.org">Pytest Team</a>, licensed under <a href="https://creativecommons.org/licenses/by-sa/4.0/">CC BY-SA 4.0</a>.</td>
</tr>

im not sure if that sufficient for someone pedantic, but i believe that's fine for now
