nmdc-lakehouse-schema
The NMDC flattened-schema product. It owns the definition of the flat, tabular shape the NMDC lakehouse writes to Parquet, independent of the data-generation, publication, and validation code that consumes it:
transforms.schema_generator— generates the flat LinkML target schema from a source schema (e.g.nmdc-schema).transforms.flatteners— the schema-driven flattener that turns nested LinkML records into flat rows, mirroring the generator's decision tree one-to-one.transforms.schema_diff— diffs two generated flat schemas so "what changed and why" is answerable.
Downstream ETL (the nmdc-lakehouse repo) depends on this package rather than defining the engine itself.
