SherpaDataset Foundation

SherpaDataset is the common data object passed through workflow nodes.

What It Carries

  • numeric data matrix
  • sample and feature axes
  • data role such as spectra or features
  • units and labels when known
  • metadata and provenance
  • target values when available

Why It Matters

Chemometrics depends on shape, axis, and target meaning. A dataset is not just an array; it also carries the scientific contract that lets nodes decide whether an operation is appropriate.
