Kontinuation opened a new pull request, #14856:
URL: https://github.com/apache/iceberg/pull/14856

   This PR updates the REST Catalog OpenAPI specification to support spatial 
predicate operators and bounding box literals. This change aligns the REST spec 
with the core Iceberg expression updates proposed in 
https://github.com/apache/iceberg/pull/14101.
   
   **Changes**:
   
   * Added `st-intersects` and `st-disjoint` to the allowed `ExpressionType` 
enum.
   * Added new schemas for bounding box literal.
   
   Here is an example of proposed JSON representation of spatial filter:
   
   ```json
   {
     "type": "st-intersects",
     "term": "column-name",
     "value": {
       "x": {
         "min": 1.0,
         "max": 3.0
       },
       "y": {
         "min": 2.0,
         "max": 4.0
       },
       "z": {
         "min": 3.0,
         "max": 5.0
       },
       "m": {
         "min": 4.0,
         "max": 6.0
       }
     }
   }
   ```
