Structured information about nodes may be generated and shared using sub-nodes. A node in a social networking system may be associated with sub-nodes that are definable by the node owner, such as menu items for a restaurant or songs in playlists for an artist. Users of the system may interact with the sub-nodes, and the interactions may be presented back on the page to a user, aggregated according to the user's connections in the social networking system (e.g., which songs your friends listened to the most by the artist, which menu items were consumed the most). Users may associate other sub-nodes to the node, such as identifying other menu items served by a restaurant, and the node owner may confirm these associations. Location awareness functionalities may be used to inform a user of highly recommended sub-nodes nearby as indicated by other users of the social networking system.
