Cool. I’ll go try that out. The only other wrinkle I can think of is that the files will need to end up in something like ${datarootdir}/share/jupyter, rather than the base ${datarootdir}. So in terms of the wheel schema you refer to, could you stash data at:
{distribution}-{version}.data/data/share/jupyter
Is that valid? I just read through the 2 wheel PEPs (PEP 427 and PEP 491) and I’m still unclear
