A listing is a marketing object that exists in the HERE Marketplace to advertize a data catalog you offer to Marketplace consumers. A listing can contain production-ready data or sample data to test market demand.
You can create a listing to be immediately available to consumers or on a request basis. In the former case, consumers get access to your data as soon as they purchase it; in the latter one, they need to request it first.
