Abstract: A method of sharing data between a sender application and a receiver application. The sender application and the receiver application execute on a computer system. The method comprises the following steps. The receiver application generates a receiver interface. The receiver application registers receiver data tokens in a registry. The data tokens correspond to the data. The sender application generates a sender interface. The sender application generates sender data tokens corresponding to the sender interface. A first token, of the sender data tokens, corresponds to one of the receiver data tokens. The sender interface receives the data and determines that the first token is registered by the receiver interface. The sender interface transmits the data to the receiver application.
