In this paper, we take the interoperability and collaborative problems among various objects belong to different smart space into account and propose the features for object service provision in smart space. On the basis of the above features, we give a semantic and automatic framework for objects service in smart space. In the framework, techniques of object service provision, context-aware, semantic reasoning, and pervasive service management are smoothly synthesized. A conceptual architecture is introduced in the light of functional characteristics of framework. It enables objects in smart space to interact spontaneously, provides semantic-integration context awareness, and supports meta-service based adaptability and scalability. Several technical challenges to develop Internet of Things need to be addressed is introduced in the last section.
