 This document explains the ML AOI Extension to the [SpatioTemporal Asset Catalog](https://github.com/radiantearth/stac-spec) (STAC) specification.
 
 An Item and Collection extension to provide labeled training data for machine learning models.
-This extension relies on but is distinct from existing `label` extension.
-STAC items using `label` extension link label assets with the source imagery for which they are valid, often as result of human labelling effort.
-By contrast STAC items using `ml-aoi` extension link label assets with raster items for each specific machine learning model is being trained.

 In addition to linking labels with feature items the `ml-aoi` extension addresses some of the common configurations for ML workflows.
-The use of this extension is intended to make model training process reproducible as well as providing model provenance once the model is trained.
