Abstract: Background: Information management play very important role in cloud manufacturing, it provides the basic service for the coordination of distributed manufacturing resources and is the central position in the entire cloud manufacturing. Materials and Methods: The information in the cloud manufacturing has the characteristics of variety, quantity and change frequently, the traditional information management system is difficult to meet the needs of cloud manufacturing environment information management. This study proposes an effective method to solve this contradiction, that is, use XML format to express resource information to eliminate ambiguity caused by different understanding. Results: Our solutions use cloud manufacturing resources in a transparent way and provide information storage, collection, query and update management. Conclusion: The practical results show that the method has good usability and efficiency.
