A method and a scripting paradigm for automatically integrating disparate information systems (e.g., web services and databases) within a given enterprise into a service-oriented architecture. A script writer generates a script using a scripting paradigm, and the resulting script automatically derives new data models, new ontological structures, new mappings, and a new web service that integrates disparate information systems. In addition to integrating disparate information systems, the scripts may be harvested to automate the metadata discovery and retrieval process. The scripting paradigm builds upon existing open-source scripting languages and is compatible with existing internet browsers, thus encouraging mass participation in the integration process.
