  • Timescale is reasonable, but people do need to find time to write, hopefully together

New things added to the scope:

  • Validation
    • Can vary experiment to experiment
    • There is scope for common tools in this area
      • Machine learning (anomaly detection is potentially interesting)
    • Statistics of validation histograms are important
  • Interaction with deployment and operations
    • Document the most popular solutions, but stay generic
  • Licensing (take ownership of that here)

Document Discussion

  • Make software more modular? Brings problems of assembly and combinatorics.
    • Industry is in much more control of the stack than "we" are
  • Is it possible to put everything into the one repository? Probably not a good solution.
  • Are our big products usable in all cases?
  • Two challenges, at least
    • Integrate the work of others in a particular experiment
      • Consistent and reproducible stack
    • Integrate the work of dispersed development communities even within an experiment
  • How can we actually monitor our performance and measure the success in meeting challenges?
    • Patricia is concerned that without this we write a lot of empty words...
    • Should strive to identify areas where HEP needs to do work
  • Integrating with non-HEP software is a challenge
  • We are not trying to address the whole of data preservation, but in so far as one can write code that's more future proofed we should say something
  • How to move away from software components that reached their end of life? Internal and external.
    • e.g. Pythia6 vs. Pythia8

Suggestion (Pere) to rework the document in terms of challenges and solutions. May bring more cohernece to the chapter.
