Advanced Conceptual Modeling of Web Applications: Embedding Operation Interfaces in Navigation Design

In the last years the integration of operation calls in the context of dynamic, personalized interfaces has become a ’must’ for Web Applications. However, existing conceptual modeling proposals have just tangentially tackled the conceptual definition of its corresponding operation interfaces, which many times involve concepts far more complex than those related to text field input. This paper presents the OO-H modeling proposal for the seamless integration of both single and multi-step operation interfaces in the context of its interface navigational model. The notation and semantics provided by OO-H allow the reuse of context information and/or navigation paths for the assignment of values to operation parameters and the visualization of operation results.
