Minutes

• Action item follow-up [0:00-0:10]
  • Cory: Slack channel in ASWF slack
    • Prefer to keep most communications on usd-interest
  • Cory: Python documentation
    • Some current issues in docstring build and release of Python documentation.
  • Cory: TAC ratification
• Outline current proposals (determine scope, identify lead)
  • Continuous integration [0:10-0:25]
    • Since USD 20.05, CI already running in Azure, no binaries yet.
    • Build flavours create a large matrix
      • Main switches are: Python on/off, Imaging on/off
    • Testing in the public Azure CI is limited (Linux only, no GPU), much Pixar-internal testing is currently image-based around linux-only perceptual diff
    • Daniel: CI working group progress on distribution/testing. Find the right way to share infrastructure between the GH Actions/Azure pipelines. Support the effort without needing to duplicate effort.
    • Kass: Can see if possible to donate GPU hardware or GPU compute instances for testing effort.
• Best practices/Knowledge base [0:25-0:50]
  • Cory: USD documentation editing / publishing workflow currently not suited to non-Pixar contributions
  • Cory: Discussed PEP-style best-practice approach with USD team, who want to avoid fracturing docs / API samples. Also want to manage the problem of versioning of docs, best practice against code.
  • Kass: Would a public wiki be acceptable?
  • Cory: USD team concerns about accuracy / maintenance
  • Kass: Wikipedia model shows robustness of decentralised and crowd-sourced contributions and maintenance. May sit alongside a more moderated PEP-style process.
  • Alan: Collection of examples need not be best-practice to be valuable. Cory: Wiki formatting much better for later discovery than email. SeanLooper: Wiki allows for discussion to be captured with examples for later distillation into best practice
  • Sue: An important factor is making examples accessible to less technical community, this includes richer media
  • Daniel: USD-wg GitHub repo does have a wiki with configurable access mechanisms: https://help.github.com/en/github/building-a-strong-community/documenting-your-project-with-wikis
  • Daniel: There may be IP / licensing questions around contributions. Cory: Action item to check with ASWF
• Determine action items/next steps [0:40-0:50]

Action Items

• Alan: Propose categories for knowledge base
• Cory: Create knowledge base category wiki doc in wg-usd.
• Cory: Discuss wiki approach with USD team.
• Cory: Discuss Azure/GH Actions GPU testing with USD team.
• Cory: Check with ASWF about legal framework for contributing to a public wiki.
