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.
