Extending the Knowledge Discovery Metamodel to Support Tasks and Presentation Behaviors of Design Knowledge

Abstract

Currently, the main objective of all programmers and designers is to render interactive systems usable and effective. So, users can complete their tasks and achieve their goals. To ensure that, programmers and designers require good understanding of system characteristics and functionality. This work focused on an approach to automate the process of extracting the system information. The approach is based on the ADM initiative as the best solution for system's evolution. The OMG ADM Task Force defines a set of standards to facilitate that, like Knowledge Discovery Metamodel, captures design knowledge needed for the construction of future user interfaces. Actually, KDM allows abstract structural and semantical aspect representation. However, no support exists for expressing behavior of system content, interaction, user control, and activities of the front-end applications. The authors hope to alleviate this lack by extending KDM model to fulfill the needs of complete abstract model construction.
