SEMbySEM in action: Domain Name Registry Service through a semantic middleware

摘要

The use of sensor networks and embedding these sensory environments into the legacy systems increase the complexity and advances the level of existing integration and interoperability problems. Apart from handling the massive data produced by each component in that kind of systems, adding more heterogeneity to the already heterogeneous architectures creates a great deal on the management side of the overall system. The purpose of the SEMbySEM project is to provide an open and generic framework for the management of mixed systems, which are made of thousands of elementary software and hardware components, using semantic representations. SEMbySEM is a EUREKA ITEA2 project, which is currently under development. This paper introduces how SEMbySEM architecture is generic enough to enable administration and management of completely software based IT systems. As the use case, management of a Domain Name Registration system is chosen and how such a system can be realized by the SEMbySEM arhcitecture through a semantic middle-ware with several viewpoints is shown. Implementing a management and supervision system on the Domain Name Registry Service (DNS) through SEMbySEM puts the wheels in action and presents a good example of the applicability of the semantic middle-ware to an IT domain. The already running DNS services with the corresponding functions and data structures are considered as the Manageable Objects of the architecture. The systems are wrapped as Web Services and published to the use of the SEMbySEM core layer conforming to the Facade specifications. The core of the architecture includes the MicroConcept implementations of the corresponding structures of the DNS system. On top of the core layer, the visualization layer of the architecture provides several powerful viewpoints for each possible user, namely the administrator, the operator, and the customer of the DNS system. Each country has its own rules for registering a domain name and those rules are subject t--o change. Even, DNS registrars may need semantic integration with other DNS systems. The management of the system is done through the semantic rules and a powerful middle-ware.
