Methods, systems and computer program products for performing interactive applications in a client-server based dialog system

Page setup and page information content for documents are used to represent interactive applications in client-server communications. Accordingly, interactive applications are performed in a client-server based dialog system, including a client and a server which communicate with one another, by transmitting documents from the server to the client which represent the interactive applications and which are independent of the client system resources. At the client, the received documents are mapped to the client system resources to thereby perform interactive applications using the client system resources. Accordingly, client-server communications may take place for many different types of clients in a device independent and transfer optimized manner. Changes to the applications may be provided on the server only.
