Abstract: Techniques for providing blocks of data to a remote computer system for insertion into a computer-generated document residing on the remote computer system. The techniques include identifying, in the central network-accessible computer system, a plurality of blocks of data, a source for obtaining current data for each of the blocks of data, and an identifier that uniquely identifies each of the blocks of data In response to a request from the remote computer system received by the central network-accessible computer system for current data for a specified one of the plurality of blocks of data, the central network-accessible computer system transmits the requested current data for the block of data from the central network-accessible computer system to the remote computer system for insertion into a computer-generated document residing on the remote computer system.
