16:00 → 17:00 Discussion

• Nico, Marjolein, Stefano, Sara, Enrique, Stelios, Dave, Gareth, John, Klaas, James P., James C.
• Dave led a discussion on metadata.
  • Believes the metadata model he has proposed is sufficient to all use cases expressed.
  • All the information is captured in the WP5 wiki... but to the non-initiate, it's not obvious what's what.
  • Agreed that Dave & John should collaborate to compile this material and provide it to WP3.
• Dave led a discussion on use cases.
  • Identified six in total.
  • We discussed three with regard to immediate/short-term goals.
    • Jupyter notebooks
    • Binder/Jupyter notebooks
    • Containerized applications.
  • Discussion of the relationship between the first two categories: how are Jupyter notebooks different from the Binder case?
    • Notebooks is intended to capture just the bare notebooks, with no information about their environment.
    • Lacking information about the environment means that this notebooks cannot be reproducible; not clear they will be available through OSSR (in the long term, at least, even if some of them are now).
    • Agreed to rule these “metadata-unencumbered” notebooks out of scope for now.
  • Containerized applications contains at least three separate classes of application: command line (container accessed by e.g. SSH), graphical (container accessed by e.g. VNC), web (container accessed by HTTP).
    • Although the machinery for launching and managing these might be similar, the underlying applications are quite different.
    • Agreed to focus on graphical applications for now.
• Stelios led a discussion on next steps.
  • Captured on this board.
  • Action on all to add their name / initials next to the “D.N” deliverables that they are interested in participating in.
