Scot Breitenfeld

No update.

Discussion of the need to extend the standard to include identifiers and references

Scot Breitenfeld

With more widespread sharing of CGNS data, for example, ML training, it might be helpful to standardize unique identifiers (global) for the file (maybe data, local?). Some examples:

• Online Resources: creator URL, publisher URL, contributors

• UUIDs, date convention, citations

• Descriptive keywords

• Lineage: audit trail for mods to original data

Should we go ahead with a CPEX?

Scot Breitenfeld Will go ahead with CPEX.

Working on the new website before creating a new development branch to prevent duplicating efforts.

Started prototyping with Python and C and will push a branch on GitHub in the upcoming weeks. (The “C” branch is a slow work in progress)

• The first draft of the API is in the branch https://github.com/CGNS/CGNS/tree/wip_cpex-0047

  • No unit test of the API yet
