+## Metadata
+
+This tab displays the `metadata` of the dataset, following the [Geoportal INSPIRE](https://inspire-geoportal.ec.europa.eu/) rules.
+
+## Parent and children datasets
+
+Between datasets can exist a relationship of parents and children. It usually happens when many datasets share the same metadata, and then are separated in multiple datasets for the data.
+From this information page it's possible to navigate throw this relationship as the parent or the children of the dataset are mentionned and linked.
+
+## Licence
+
+There is the possibility to download the licence from this page.
+The way we retrieve it is a bit triclky, as there is no specific metadata properties for the licence.
+We check in the `links` items, and if on of them contains in its name `"Licence"`, then we use the url associated to this `link`.
+So when we click on the licence button in the information page, it uses this url we retrieved for the `link` metadata.
