api.models

This module is a collection of pydantic models, which siibra instances will serialize into.

This is a deliberate design decision, since this could provide the type hinting with the least amount of dependency.

Processes import from this module must not require siibra installed.

Similar to MIME types This can allow clients to decide on which level of specificity to stop on parsing the data.

Additionally, fastapi response model type infer is not perfect.

e.g.

class B(BaseModel): pass

Fastapi will reduce the above will be reduced to B.

To circumvent the problem, all super classes must start with _.

Since we cannot directly control openminds, we ignore openminds types.
