infermap is a schema-mapping engine. Give it any two field collections (CSVs, DataFrames, database tables, in-memory records) and it figures out which source field corresponds to which target field, with confidence scores and human-readable reasoning. Available as a Python package on PyPI and a TypeScript package on npm, with mapping decisions verified bit-for-bit by a shared golden-test parity suite.
