Abstract: A platform for device-independent business application development, based on XML-based type instructions and associated parameters, is described. The platform supports the hierarchical mapping of business needs onto business processes, action steps and OS and device-independent application descriptions to be interpreted, build, and executed on client devices. Upon receipt of the application description by a client device, the latter being configured to read and interpret the XML-based instructions and parameters of the application description, it creates a local application. The operating system selection, user interface, driver, hardware and firmware specific functionalities and control are taken care of by the client device.
