Abstract: Users are matched to items and recommended friends in a social merchandising system. During registration, a user profile is created for a user among a plurality of users in the peer-to-peer marketplace. To calculate a compatibility score, a social genome is determined for the user based on social networking characteristics associated with the user. Also, a merchandise genome is determined for the user based on item characteristics associated with the user. Results are organized into a feed for the user based on the compatibility score and time. Feeds display items of friends, or as influenced by social connections and interactions.

Abstract: A digital item tracking system drives e-commerce with an order state that is determined based on processing events, shipping events and payment events. When a transaction occurs in a peer-to-peer marketplace the order state is updated as events occur through the point that an order is accepted by a buyer. The order can also cause an exception in which reverse digital item tracking is needed.
