Generic Screen Representations for Future Proof Systems - Is It Possible? Two-model approach to a generic GUI

Semantic interoperability should not only cover system interpretation of incoming information, but should be extended to include screen representation. This article describes a two-model approach to generate a screen representation for archetype-based information, which is inspired by the two-model approach used by openEHR for their archetypes. It provides a separation between software-related display knowledge and domain-related display knowledge and is designed with reuse of components in mind. This approach leads to a flexible GUI that can adapt not only to information structures that are not predefined within the receiving system and display them in a meaningful way, but also to novel ways of displaying the information. We are working on a proof of concept implementation to validate the approach.
