Extended web infrastructure for business applications

Abstract

A method and system for refreshing client-data is provided. A client provides a predefined layout document and predetermined client-data stored in a client-data cache. The layout document uses the client-data via predefined client-side application independent functions. The client receives a sync-request to synchronize the client-data with corresponding server-data of a server. The client creates a client-data descriptor. The server generates a server-data descriptor that is dependent on the client-data descriptor, a server-side copy of predefined client-data and the server-data. The client updates the predetermined client-data in the client-data cache according to the server-data descriptor. The client-data, the client-data descriptor and the server-data descriptor have a browser independent format.
