Systems and techniques to provide a unifying navigation model with a navigation service that provides an interface to information sources. In general, in one implementation, the technique includes: uniting navigation hierarchies from different application sources, and providing a unified navigation area based on the united navigation hierarchy. Uniting the navigation hierarchies can involve supplying a navigation service with a navigation object model that provides, to a presentation layer, a homogeneous view of navigation information from the different application sources. Providing the unified navigation area can involve displaying a navigation window in a portal presentation, the navigation window including navigation links to resources of the different application sources, and the navigation links being organized according to the united navigation hierarchy.

Unifying navigation model

Systems and techniques to preserve state information in a client-server environment. In general, in one implementation, the technique includes: storing, in a shared memory of a client, a scripting object that retains state information for an original document, and cloning the stored scripting object to a newly loaded document. Storing the scripting object can involve copying a scripting object reference to the shared memory to cause retention of the scripting object by the client during document loading. Cloning the stored scripting object to the newly loaded document can be performed recursively, and can involve creating a new scripting object in the new document and copying data from the stored scripting object to the new scripting object. The state information retained in the scripting object can be navigation information associated with the loaded document, and the loaded document can be a portal page in a portal system.
