Patent ID: 8769439

Claim:
A method for modifying a hierarchical navigation topology comprising nodes and edges connected between the nodes in a web application environment, in which the hierarchical navigation topology of a web page corresponds to a predetermined topology level and displays one or more applets, the method comprising: defining a user-specific topology based on the navigation topology entered by the user; storing information for recovering the user-specific topology in a database, wherein the information for recovering the user-specific topology comprises difference information between the navigation topology and the user-specific topology; receiving a user login from the user subsequent to the defining of the user-specific topology and the storing of the difference information between the navigation topology and the user-specific topology; initiating rendering of the navigation topology in response to the user login; stopping the rendering of the navigation topology upon detection of a dynamic node therein; performing a dynamic assembly transformation upon detection of the dynamic node to obtain the user-specific topology, the dynamic assembly transformation comprising: detecting an identity of the user; based on the identity of the user, reading the difference information between the navigation topology and the user-specific topology from the database; generating the user-specific topology by combining the navigation topology and the difference information; and generating a user specific context topology for the user from the user-specific topology, the user specific context topology representing a modified topology of the user-specific topology that is configured specifically for display on a type of computer system used by the user to perform the computer login; and displaying one of the user-specific topology and the user specific context topology to the user in response to completing the dynamic assembly transformation.
