12. A network system comprising: a storage that holds a web service comprising at least one source code with a plurality of web service operations arranged in a logical succession, wherein the server performs the operations of: analyzing the web service; inferring annotations based on the analysis to define inferred annotations, each inferred annotation referencing at least one of the web service operations, the storage holding the inferred annotations; adding the inferred annotations to the web service to define an annotated web service; and a modeling tool running on a processing unit and configured to automatically read the inferred annotations and generate a dynamic state chart diagram of the annotated web service based on the inferred annotations by arranging the inferred annotations according to the logical succession of the web service operations, the dynamic state chart diagram representing behavior pattern and being configured to be represented using a representing unit.
13. The network system according claim 12 , wherein the modeling tool generates a superior dynamic state chart diagram using the dynamic state chart diagram of the respective local web services of the respective servers.
