| Those *Metadata* can be filled out through a three-steps *Wizard* in which you have to provide all mandatory information to complete the process. Those three steps are described below.

* *Basic Metadata*

  In the first step the system asks you to insert the following metadata (required fields are highlighted with red outlines):

  * The *Thumbnail* of the map (click :guilabel:`Edit` to change it);
  * The *Title* of the map, which should be clear and understandable;
  * An *Abstract*;
  * The *Creation/Publication/Revision Dates*  which define the time period that is covered by the map;
  * The *Keywords*, which should be chosen within the available list;

  No further mandatory metadata are required in the next step so, once the required fields have been filled out, a green :guilabel:`Done` button will be visible in the screen.
