+This document explains the COCOJSON Extension to the [SpatioTemporal Asset Catalog](https://github.com/radiantearth/stac-spec) (STAC) specification.
+
+The COCOJSON format (Common Objects in Context JSON) is a standardized format used to represent object annotations along with metadata including 
+segmentations masks, pixel bounding boxes, and annotation categories commonly used in computer vision. This extension integrates the standarized 
+COCOJSON fields into the STAC Item spec, enabling a practitioner to embed COCOJSON annotations within STAC Items.
