 # Information
 
+This tab shows metadata related to the visited dataset.

 ![Information](../../../../assets/webapp/info.png)
 
-## Metadata
+Let us note that metadata:
+
+* are originally filled in by the back-office team via the [GeoNetwork](https://www.geonetwork-opensource.org/) off-the-shelf application;
+* comply to two different templates: 
+    * ISO19139 for geographical datasets;
+    * Dublin Core for non-geographical datesets;
+* are indexed in Elasticsearch by a [custom indexer](https://forge.grandlyon.com/web-et-numerique/web-et-numerique-internet/data.grandlyon.com/web-portal/components/indexers/metadata-and-data), in order to enable full-text searches.
+ 
+This Web Application retrieves metadata from Elasticsearch, by applying a filter on the `slug` field.
 
-This tab displays the `metadata` of the dataset, following the [Geoportal INSPIRE](https://inspire-geoportal.ec.europa.eu/) rules.
+*QUESTION: do you confirm that such a filter is the right one?*
