APPLICATION DESCRIPTION LANGUAGE

摘要

A method and system for creating and modifying computer applications (206) using an application description language (202) based on a markup language is provided. An engine (204) creates, connects, and initializes objects corresponding to entities, and specified by entity tags. A factory may be specified by an entity tag and used to create a plurality of entities. Applications (206) are specified in a plaintext descriptive language using a markup language such as XML, enabling applications (206) to be easily developed using object oriented techniques and abstraction. Altering preexisting applications is also simplified. Finally, an application (206) may be dynamically reconfigured when the application's data (208) changes. Type checking and conditional creation of entities is supported.
