Format for Listing Description

As for as I remember the Descriptioninformation will be just one text in blockchain and then by the wallet/API decheifered. Now I wonder which other fields than description text and picture are there and if there is a field for countries the product will be shipped to and if it is Physical or digital to enable filters to hide all products I can’t receive anyhow?

Is there any place the information for this format is visiable or is it?

The stagenet wallets showed all sorts of fields. All of those fields form part of the Description field text string, formatted for TWM.
