Conceptual Design and Development of Information Services

Due to the development of the internet and cable nets information services are going to be widely used. On the basis of projects for the development of information services like regional information services or shopping services we develop a method for the creation of information systems and services to be used through different nets. The approach is based on the codesign of data, dialogues and presentations. The main concepts are information units and information containers. These basic concepts for information services are presented in this paper. Information units are defined by generalized views with enabled functions for retrieving, summarizing and restructuring of information. Information containers are used for transfering information to users according to their current needs and the corresponding dialogue step. Size and presentation of information containers depend on the restrictions of the users environment
