Abstract: Method, system, and computer program product for instantiating a template in a composite application infrastructure. A template that describes a composite application having a plurality of application components is created. The template includes a composite application component assembly descriptor which lists each application component of the composite application. The template is stored in a template library. The composite application is instantiated using the template for creating at least one composite application instance. In an application instance registry, composite application instance(s) and instance information related to the composite application instance(s) is/are registered. The composite application instances are transiently represented in the application instance registry by a respective table entry without creating a real object. The real object that is dynamically created represents a particular composite application instance during a composite application usage session.

Abstract: There is provided a method and data processing system for restructuring web content which consists of a plurality of web pages. The method comprises the steps of generating a log file which comprises a history of web pages. The history of web pages comprises all web pages that have been selected by a user from the plurality of web pages. An access frequency is determined for each of the selected web pages by use of the history of web pages. A subset of web pages is determined which comprises the web pages that have been accessed by the user with the largest access frequency. This subset is limited to a maximum number of web pages. The plurality of web pages is generally arranged in a tree structure. The tree structure is rooted at the starting webpage.

Abstract: A predetermined business task of a composite application can be fulfilled. The composite application can include a set of components. The composite application is instantiated by a template means and a predefined collaborative context module controls the interaction of the set of components during the runtime of the composite application. A set of components fulfilling individual services on individual different server systems is leveraged by the composite application. During the instantiation of the composite application from a template, the referenced components (as types) are instantiated leading to runtime instances of these components. The interaction of the different components is controlled on individual different server systems utilizing a primary context module.

Abstract: The present invention relates to the field of network portals and in particular to a method and system for exchanging data between components of one or more composite applications implemented on a portal server, wherein the components are programmed independently from each other. An embodiment of the invention includes: automatically intercepting I/O data being input or output respectively to or from the components or a browser; extracting data objects from the I/O data; determining for a source component, which of the data objects match input requirements of which other potential target components; selecting matching data objects for a matching target component; and transferring the matching data objects to the matching target component.

Abstract: This application explores the value of Web 2.0 techniques to perform adaptation based on semantic annotations. Semantic annotations are used to derive user and context models which in turn are used for performing the re-ordering of page layouts or the dynamic transformation of navigation topologies to provide a more user specific portal user interface. The semantic annotations also allow similarities and relationships to be calculated between resources and users so that additional relevant annotations and/or resources can be recommend to the user.

Abstract: The invention relates to a method of providing a composite portal application for a portal server application environment. In accordance with an embodiment of the invention, the method comprises: providing application components in machine readable code for forming the portal application; providing an application assembly descriptor in machine readable code, wherein the application assembly descriptor comprises meta-data, wherein the meta-data specifies how the application components have to be assembled to provide the composite portal application on the portal server application environment; providing a set of functions; using the functions of the set of functions as points of variability in the meta-data, wherein the functions are adapted to be evaluated by the portal server application environment.

Abstract: The invention provides a system and program product for caching dynamic portal pages without changing the existing caching proxy infrastructure or the transportation protocol used by providing an advanced caching component. An advanced caching component provides the functionality that additional dynamic page specific cache information is provided as part of the response including the portal page. Each component in the portal that dynamically contributes page fragments to be aggregated to a portal page provides dynamic component specific cache information which includes component specific cache scope and expiration values.

Each component in the portal that dynamically contributes page fragments to be aggregated to a portal page provides dynamic component specific cache information which includes component specific cache scope and expiration values. The component specific cache scope and cache expiration values are used to calculate dynamic page specific cache information resulting in a common minimum cache scope and a common minimum cache expiration values for a portal page to be aggregated.

Abstract: A portal server comprises memory, a profile manager, a profile selector, and a profile initiator. The profile manager is configured to manage a plurality of profile records in a profile database. The profile selector is configured to select at least one of the plurality of profile records based on context data collected at a client and context data collected at the portal server. The collected context data corresponds to particular user interaction activity with the portal server. The profile initiator is configured to adapt a user interface based on the profile selected by the profile selector.

Abstract: A method and respective system for adapting the user-visible structure of a portal to the needs of a user, wherein the portal structure is stored in a content model, wherein a user interface component is provided for controlling the layout of the plurality of pages rendered at said portal, and wherein a model management component comprises the functionality for performing persistent content model modifications.

Abstract: The disclosed system relates to the field of network computing, and in particular to method and system for designing a Web Portal including a hierarchical structure of portal pages and portlets for accessing Web contents accessible via the Portal. The disclosed system operates to improve Web application user navigation. During navigation by a user in the topology of the Web portal, the disclosed system automatically senses information about the navigational behaviour of the user for each page visited during said navigation. The disclosed system derives page hits and page target hits from the sensed information, wherein page hits are defined when pages are clicked on for reaching another page, and page target hits are defined when a user clicks on pages in order to perform a page-specific task or to receive some page-specific information.

Abstract: A method for differential rendering a portal page that includes a plurality of page elements (10, 12, 14) and refreshing the portal page. The method includes providing a complete portal page (20, 22). A request for the portal page is then sent and/or received (28). The request can represent user events. In a next step, page elements (10, 12, 14) of the portal page to be updated are identified (30, 31) on the basis of the user events. A page delta is then calculated (32), wherein each page element (10, 12, 14) is associated with a refresh policy depending on the semantics of the respective page element (10, 12, 14). The page delta can include the markup elements of the page elements to be updated. Next the page delta is transferred (34) to the existing portal page and merged (40) with the existing portal page.
