A Product Lifecycle Data Management Framework Based on Resource Meta-model

Integration and unified management of data scattering along the lifecycle chain is the primary problem to be solved in PLM field. In this paper, a framework based on resource meta-model is proposed to integrate and manage product lifecycle data. Firstly, the structure of this framework is presented. Then, the resource meta-model is defined and the functions, structure and generation method of the model are given in detail. To better control resource accessing operations, a resource accessing control mechanism is proposed to make sure that product lifecycle information in different stages is accessed by authorized roles in valid way. Finally, a case study is presented to demonstrate the application of our framework for PLM. The result shows that our proposed method could integrate and manage heterogeneous data during product lifecycle more flexibly.
