A framework is presented that can be used to create and execute software applications that include a user interview. The framework includes run-time engines and a data repository. The run-time engines include an interview driver. The data repository includes interview instructions and model information. The interview driver generates or modifies an instantiated data model by using the interview instructions and model information to obtain information from a user. The interview instructions include flow control information, prompts, and user interface (UI) information. The model information includes a meta-model, a data model, and an instantiated model. Once an instantiated model has been created, it can be used to generate an application-specific document, such as a tax form. Since the application is executed based on the contents of the repository, the application can be modified by changing the contents of the repository. |
