dataset_manifest

io.github.witanmarkets/witan · Verify this server

The manifest of a dataset version (requires auth): schema, totals, and the content-addressed Parquet parts (sha256, bytes, records), each with a download URL valid 15 minutes — the way to fetch a whole version as files. Use it to download or mirror a version; to look at records here, read_dataset pages them and query_dataset aggregates them on the server. Parts are shared across versions: pass have, the sha256s of the parts you already hold, and those come without a URL. The bytes of the parts that get a URL count toward your egress; the rest count nothing. The manifest is signed by the origin (Ed25519, keys at /.well-known/witan-keys) over its content without URLs, so it verifies either way.
