Formats

rustac "speaks" three forms of STAC:

• JSON: STAC is derived from GeoJSON
• Newline-delimited JSON (ndjson): One JSON item per line, often used for bulk item loading and storage
• stac-geoparquet: A newer specification for storing STAC items, and optionally collections

We also have interfaces to other storage backends, e.g. Postgres via pgstac.
