 ## Creating discovery metadata

 Update the following values in the discovery metadata configuration:
 
-- `wis2box.topic_hierarchy`: the topic hierarchy that categorizes the data (this value should be the same as the definition in your newly created data mapping).
-- `wis2box.country`: 3-letter country code in lower case
-- `wis2box.centre_id`: your centre id as defined in the previous exercise
-- `metadata.identifier`: a unique identifier consisting of `urn:x-wmo:md:[country]:[centre_id]:[dataset_name]`, where `[dataset-name]` can be any name of your choosing.  Remember this value for API validation later on in this exercise
 - `identification.title`: a human readable title describing your data
 - `identification.abstract`: a human readable description describing your data
-- `identification.dates.creation`: when the discovery metadata was created (today's date)
-- `identification.extents.spatial (bbox)`: the bounding box coordinates of your data (minimum longitude, minimum latitude, maximum longitude, maximum latitude), in decimal degrees
-- `identification.extents.temporal (begin)`: the begin and end time of your data (keeping the end time to `null` is suitable to ongoing observations)
+- `identification.extents.temporal (begin)`: the begin (`BEGIN_DATE`) (`YYYY-MM-DD`) and end time of your data (keeping the end time to `null` is suitable to ongoing observations)
 - `contact.pointOfContact`: your organization's point of contact information
 
+!!! note
+    Many values have been pre-populated as part of the [Initializing wis2box](../initializing-wis2box) practical session, however you will want to ensure they are correct / accurate for your dataset.
+
 !!! tip
     The configuration is based on the YAML format.  Consult the [YAML cheatsheet](../cheatsheets/yaml.md) for more information.
 
 !!! tip
-    Ensure that bbox values are correctly signed (for example, use the minus sign [`-`] for southern or western hemispheres.
+    As the `identification.extents.spatial.bbox` coordinates are pre-populated, you may want to update the coordinates if the dataset coordinates are not based on your country's administrative boundaries.  Feel free to update this value accordingly, ensuring that values are correctly signed (for example, use the minus sign [`-`] for southern or western hemispheres.
