A Configurable WoT Application Platform Based on Spatiotemporal Semantic Scenarios
针对物联网向Web of Things转型中数据语义弱、与场景结合松散的问题，提出一种基于时空语义场景元模型的可配置平台，通过数据、事件流和服务封装来抽象描述场景，并支持按需调整业务规则。
With the transformation of Internet of Things to Web of Things (WoT), a variety of applications are required to deal with huge volumes of real-time and heterogeneous data. However, in most applications, due to the weak semantics of data itself and the loose combination with specific scenarios, it is sometimes difficult to depict the spatiotemporal feature of the scenario in an application only through the data. In this paper, a spatiotemporal semantic scenario meta-model-based configurable platform is proposed for the development of WoT applications to address this issue, based on the data configuration, event stream configuration, and service encapsulation, the entire WoT scenario can be depicted with an abstract data model and related rules, and the business process can be changed by redefining corresponding rules when requirements change. A case study is given to verify the feasibility of our platform. The result shows that the platform can provide background support for WoT applications in a promising way.
