The Operating system is very complicated software and its size is very large. The challenges managing operating systems services have huge number of services and operating systems updates software. In this paper we concerned about Exokernel operating system structure for more generalization and reusability. For facilitate knowledge sharing and reusability the ontology based has been developed in artificial intelligence. Also semantic character in ontology based will reduce the number of services instead to keep all of them. In this paper, ontology refers to a layer of interfaces and services that resides between the application and the operating system is proposed. The proposed services ontology based facilitates the development, deployment and management of embedded system. Also The proposed ontology based suitable for any operating system. This paper will use Service-Oriented ontology architecture to management the operating system services development.
