API expectations for file_paths

[elray1]

The documentation for file_path arguments here says that file paths are relative to the hub's model-output directory. When validating a model metadata file, I'm not sure what I should expect for the file_path:

• It might be nice if it included the model-metadata folder, e.g. "model-metadata/hub-baseline.yml". This would allow me to check that it is correctly located inside of the model-metadata folder.
• But this would be inconsistent with what's done for file paths to model output submissions, where the first hub-specific part of the path is removed. That is, if we remove model-output from the file path for model output submissions, it seems like we should similarly remove model-metadata from the file path for model metadata submissions.

Related question: maybe the idea is that the whole reason we know to call the validation functions for a model metadata or model output file is that it is located within that folder of the hub? So that actually, the check that a metadata file that's being validated is located inside of model-metadata is irrelevant, because we would only be validating it as a metadata file if it's in that folder? And any file that is in a submission that's not in either model-output or model-metadata will just get a generic error thrown saying the file is not in an expected location?

FWIW, I'm going with the second option -- we do not include model_metadata as part of the file_path.
