+           address:      'Address',
+           city:         'City',
+           postcode:     'Postcode',
+           country_code: 'Normalized country code (ex: FR)'
+         },
+         (Date.today + 5.days).strftime('%d/%m/%Y'), # Estimated departure date of the package
+         1000 # Computed weight of the package (in grams)
