Abstract: A web-based application constructor can be used to construct a web display. A specification, for constructing a web display to contain page components that display data from heterogeneous data sources, may be created. The page components may be associated with uniform resource locators. Data from heterogeneous data sources may be retrieved to produce the web display. Display and update of the page components may be controlled using the uniform resource locators. User-selectable options may allow annotation of the page components for a page with comments.

Abstract: A web-based application constructor can be used for constructing a web display. The web-based application constructor can obtain data from heterogeneous data sources to produce the web display. The web display can contain page components and display the data from at least some of the heterogeneous data sources. The page components can be accessible by URLs.

Abstract: A web-based application constructor can be used to construct a web display. The web-based application constructor can obtain data from heterogeneous data sources having Web Services schemas to produce the web display. The web display can contain page components and can display the data from at least some heterogeneous data sources. A versioning system can keep track of changes to page components, page layout, searches, and text to allow users to make changes without administrative approval.

Abstract: One embodiment of the present invention is a method of converting a user interface. A control based class can be extended to produce a Java Server Face. The Java Server Face can be converted to create an ASP.NET user interface.

Abstract: Systems and methods for extending ad hoc information around structured data. The method for one embodiment comprises several steps. One step is creating a web interface for structured data. One step is combining the structured data through the web interface with unstructured data, wherein one or more users can collaborate to combine the structured data through the web interface with the unstructured data without administrative approval. One step is producing groups of pages extending ad hoc information around the structured data, wherein versions of the groups of pages are tracked.
