Versioning

[cisaacstern]

We will need a versioning scheme for these schema. I'm punting on this for now to move forward, but it will need to be addressed before too long.

The changes here will be tightly coupled to those in pangeo-forge-orchestrator, which also doesn't have a versioning scheme, so perhaps these two will be linked in some way. Where that breaks down is that pangeo-forge-orchestrator will be updated much more than this repo, so perhaps they need to be versioned separately?

We're getting into a proliferation of versions here! Is there some way we can uniform/harmonize versioning across:

• pangeo-forge-recipes
• pangeo-forge-runner
• meta-yaml-schema
• pangeo-forge-orchestrator

?

How do other modular platforms manage this?
