Improve CoverageJSON Ecosystem 1: Python Validator

[chris-little]

1. To improve the CoverageJSON ecosystem, a python validation tool to validate values and aspects that the JSON Schema cannot would be useful.

(In the longer term, if CoverageJSON becomes a full OGC Standard, the validator would be written in Java.)

This comment is a note-to-self to define the requirements for this, with a view to defining a project. Could include requirements for validation and conversion between xarray, pandas, etc.

Would need to build on existing work with the schema.

I think one exists at covjson-validator although not for conversions

[jonblower]

Yes, that one validates against the schema, but there are other rules that the schema can't cover, which we would have to validate some other way. And you're right, it doesn't do conversions
