Abstract: Aiming at the highly dynamic opening of manufacturing cloud service's operating environment, the meta-modeling framework for cloud service supporting evolution was put forward based on the analysis of modeling requirements of manufacturing cloud service. The meta-model architecture for cloud service in the semantic representation layer of this framework was studied emphatically. In meta-meta-model layer of cloud service, the formal definition of meta-meta-model and the conceptual model of cloud service were presented. In the meta-model layer of cloud service, the model structure of business master object, business meta object and business meta data as well as model structure of evolution operation object and evolution log object were elaborated. In the model layer of cloud service, cloud service ontology was established based on Web ontology language. Based on the above, the evolution process model of cloud service was presented. A prototype of manufacturing cloud service management platform for mould industry was developed, and a practical case study was provided to demonstrate the feasibility and effectiveness of this modeling method for cloud service.
