Auto-parsing of Python schemas to extrude StructTypes representations in Julia

[kshyatt-aws]

Describe the feature you'd like
It should be possible to use the Smithy representation of the Amazon Braket Schemas to automatically generate JSON versions of all the Braket Schemas, which JSON3.jl and StructTypes.jl can then digest to generate the corresponding Julia types.

Is this feature already present in the Python SDK?
N/A

How would this feature be used? Please describe.
This would make it possible to keep the Braket.jl versions of the schemas up to date automatically.

Describe alternatives you've considered
Currently this must be done by hand.

Additional context
It's necessary to replicate some of the implicit information encoded by the type hierarchy in Python that is currently represented with traits in Julia, e.g. target count. Also, support for the Pydantic restrictions on fields would be helpful.

Are you aware of any examples in other AWS open-source projects that make use of Smithy schemas to support Julia in this way? May be helpful to reference. I will do some research on this myself at some point, so no concerns if you aren't immediately aware of any relevant projects.
