How to Create Evolving Information Models by a Layered Information Architecture

Flexibility and adaptability of information systems has become increasingly important especially in Internet-based distributed applications. Class-based methods that are efficient in object-oriented programming tend to become too rigid in Internet environments. A twolayered architecture is here analysed as an alternative approach. The paper attempts to show in what sense Internet and the WWW are two-layered architectures and how the evolving “Internet of Things” can be conceived in order to maintain the flexibility of Internet. The Internet of Things provides new and unforeseen innovations also for how industrial enterprises can co-operate and exchange information. The DIALOG implementation of the Internet of Things presented in the paper has been used in such applications and also follows the principles of the two-layered architecture.
