  • schema-map: propose a source-column to target-schema crosswalk.
  • schema-refactor: apply a crosswalk, renaming/ dropping columns.
  • schema-crosswalk: map and apply a crosswalk in one call.
  • schema-fill: stamp each row's real depth and cascade hierarchy columns down.
  • schema-join: copy each child's best-overlapping parent's hierarchy columns onto it.
