An approach provides machine and a human user interaction in support of dialog flows. A first state file is generated and specifies a plurality of states of a dialog with the human user. The first state file includes logic for transitioning among the states. A second state file is also generated. The second state file specifies a plurality of states of the dialog and includes logic for transitioning among the states, wherein a common process is utilized to interpret the first state file and the second state file. The common process loads one of the state files and determines an appropriate one of a plurality of resources to populate with data associated with the dialog.
