 Tracking dataset upload progress
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-When an upload request is executed, GeoNode creates an “upload object” and keeps updating its state and progress (it’s a property attribute, calculated on getting the response) attributes as the resource is being created and configured in Geoserver.
-The states used include:
-    - READY
-    - RUNNING
-    - PENDING
-    - WAITING
-    - INCOMPLETE
-    - COMPLETE
-    - INVALID
-    - PROCESSED
-
-When the dataset is successfully uploaded, the final state of the upload is set to ``PROCESSED`` and progress is calculated as ``100.0``.
-
-In order to view ongoing uploads, and their states, you can use the API ``GET /api/v2/uploads`` or ``GET /api/v2/uploads/{id}`` if the upload id is known. You can also filter uploads with state.
-Eg ``GET /api/v2/uploads?filter{state}=PROCESSED``
+When an upload request is executed, GeoNode creates an "Execution request" and keeps updating its state and progress (it’s a property attribute, calculated on getting the response) attributes as the resource is being created and configured in Geoserver.
+An execution can be in one of the following status:
+    - ``ready``
+    - ``running``
+    - ``failed``
+    - ``finished``
+
+When the dataset is successfully uploaded, the final state of the upload is set to ``finished``.
+
+In order to view status of the execution, the API method ``GET /api/v2/executionrequest/{execution_id}`` where ``{execution_id}`` is the value returned by the initial call to the upload API. 
+
+The returned object contains, beyond all the information related to the execution, the inputs that were passed to the execution request, and output params specific to the type of execution.
+In the case of a dataset upload, the output params contain the URL of the catalog page for the new datast.
