At the moment we are relying on LHAPDF for the whole server/set/organization management. I don't think we really want to reimplement the whole thing, but it would be nice to have at least some feature that is able to download PDFs to /usr/share/pdfflow or even /usr/share/LHAPDF so that the library can work stand-alone-y.

@scarrazza what should we do about this? I was thinking it might make sense to make a fork of LHAPDF with only the set management stuff (maybe open an issue in their repo) so it can be distributed via pip.
I think reimplementing the stuff ourselves is both unnecessary extra work and sort of ugly if we are going to be using their servers...

We got no answer so I would do two things:

  1. Add a mechanism so that one can point to a directory with an environment variable and get the PDFs from there.
  2. Do our own (maybe vp-like once NNPDF4.0 is open sourced)
