@hannesm : The list of data sources in the documentation could also be updated to add this new source. https://github.com/google/osv.dev/blob/master/docs/data.md

This updates this page: https://google.github.io/osv.dev/data/

Thanks for your comment. FYI, this is not mentioned in the issue template for a new source (see #4581).

Anything I can do to move this forward? It looks like CI systems await approval (though I can't see the oss-vdb worker output).

I believe you can run most of the tests locally as well

make lib-tests
make lint

See Makefile for other tests available, but I think lib-tests is the one you need, though it will require you to have the poetry installed. (See CONTRIBUTING.md for full list of prerequisites. )

LGTM, though please fix the linting issues.

Use make lint to run the linter locally.

yapf -i <file> to format the file.
