Data communication networks allow data, such as electronic documents, graphical images or audio files, to be retrieved from remote sources for use in local applications, such as synchronization environments. A device may store metadata useable to navigate and locate data stored on the remote source, and an application on the device may use the stored metadata to determine what data to retrieve from the remote server based on the currently accessed data. The metadata may comprise a portion of the data on the remote source that is displayed on the device while the data are being retrieved.
