The use of logic for routing data. Metadata that is associated with data residing on a first computing system is sent to at least a second computing system. The metadata is structured so that when interpreted by the second system, the second system provides an appearance that the data is local. The first system then receives a communication from the second computing system, demonstrating that a user has interacted with the appearance of data on the second system. Logic may be applied to determine how and when to send the data to the second system. Based on the determination made by applying logic, the data is sent to the second system in a manner that is associated with the identifier for the entire data.
