Abstract

Computer-implemented methods, computer systems and computer program products are provided for creating and processing a browser compliant human interface description. A predefined application specific human interface description using application specific layout elements is transformed into a standardized human interface description using basic layout elements. The standardized human interface description is decomposed into a human interface layout template and a data description. A data instance is instantiated from the data description. The data instance is merged with the human interface layout template into an individual browser compliant human interface description, which is then rendered to prompt a user for data input. The received data from the user are stored in the data instance. The status of at least one layout element is either stored in the data instance or in a runtime-copy of the standardized human interface description.
