+### GEOMETRY
+
+`GEOMETRY` is used for geometry features in the Well-Known Binary (WKB) format
+with linear/planar edges interpolation. It must annotate a `BYTE_ARRAY`
+primitive type. See [Geospatial.md](Geospatial.md) for more detail.
+
+The type has two type parameters:
+- `crs`: An optional string value for CRS. If unset, the CRS defaults to
+ "OGC:CRS84", which means that the geometries must be stored in longitude,
+ latitude based on the WGS84 datum.
+- `crs_encoding`: An optional enum value to describes the encoding used by the
+ `crs` field. Supported values are: `SRID`, `PROJJSON`. If unset, `crs` can be
+ arbitrary string.
+
+The sort order used for `GEOMETRY` is undefined. When writing data, no min/max
+statistics should be saved for this type and if such non-compliant statistics
+are found during reading, they must be ignored.
+
+### GEOGRAPHY
+
+`GEOGRAPHY` is used for geography features in the WKB format with an explicit
+(non-linear/non-planar) edges interpolation algorithm. It must annotate a
+`BYTE_ARRAY` primitive type. See [Geospatial.md](Geospatial.md) for more
detail.
+
+The type has three type parameters:
+- `crs`: An optional string value for CRS. It must be a geographic CRS, where
+ longitudes are bound by [-180, 180] and latitudes are bound by [-90, 90].
+ If unset, the CRS defaults to "OGC:CRS84".
+- `crs_encoding`: Same as `GEOMETRY` type above.
+- `algorithm`: A required enum value to describes the edge interpolation
Review Comment:
Yes, I can follow the same thing on the `algorithm` field.
