GridDoc: A End-User-Oriented Presentation Model for Resource Integration

In face of the mass data resources in the Web, end users want to be able to access and use them conveniently. GridDoc is an end-user-oriented presentation model, which enables end users to design and implement customized resource integration in a simple and consistent way. GridDoc model is proposed, which comprises the layout, controls set, XML schema, data source, virtual data services set and convergent data services set. The service virtualization mechanism is used to support late binding between GridDoc and the underlying data services. GridDoc is standard- based, loose-coupled and coarse-grained in nature, thus it allows the individual components to evolve independently. The effectiveness is evaluated using some real cases.
