Abstract: In an online marketplace environment, a seller of items can provide information relating to items for sale on one or more online sales channels to a connection provider. In one implementation, a method describes receiving a product data file (PDF) from a seller, in which the product data file includes information relating to one or more items for sale by the seller. The method also includes facilitating a sale of the one or more items through one or more online sales channels, in which the product data file further includes one or more data fields for enhanced selling features. The enhanced selling features include selling features in addition to baseline features. The baseline features include providing online listing capabilities for the one or more items being sold.
