Using an instantiated model to generate an application-specific document

摘要

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 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. A transformer and application logic are used to generate an instantiated application-specific model. The instantiated application-specific model and the document renderer are used to generate an application-specific document.
