9. The computer-implemented method of claim 8 and further comprising: generating a representation of a dialog definition user interface display comprising a dialog type selection user input mechanism; receiving an indication of user actuation of the dialog type selection user input mechanism; based on the indication of user actuation of the dialog type selection user input mechanism, define a dialog type for the dialog; and generate the metadata definition based on the dialog type.
9. The computer-implemented method of claim 8 and further comprising: generating a representation of a dialog definition user interface display comprising a dialog type selection user input mechanism; receiving an indication of user actuation of the dialog type selection user input mechanism; based on the indication of user actuation of the dialog type selection user input mechanism, define a dialog type for the dialog; and generate the metadata definition based on the dialog type. 10. The computer-implemented method of claim 9 wherein generating a representation of a dialog definition user interface display comprises: generating a representation of a set of dialog type selection user input mechanisms; receiving an indication of user actuation of a particular one of dialog type selection user input mechanisms; in response to the indication of user actuation of the particular dialog type selection user input mechanism, selecting a particular dialog type and generating a representation of a configuration display with a configuration user input mechanism; receiving an indication of user actuation of the configuration user input mechanism; and based on the indication of user actuation of the configuration user input mechanism, configuring a dialog of a type corresponding to the particular dialog type.
