摘要 提出一种实时分布元数据管理的软件体系结构。结构基于公共仓库元模型(CWM)规范,以CWM元模型规定元数据集成、交换内容,XML元数据交换(XMI)提供实时元数据交换和共享机制,仅需一个接口驱动程序,即可实现对应分布元数据的动态读取。原型实验已验证了体系结构对元数据互操作和实时分布存取的可行性和有效性。 A software architecture for real-time distributed metadata management is proposed. The architecture is based on common warehouse metamodel (CWM) specification. CWM metamodel identifies the structure and semantics of integrating and exchanging, while XML metadata interchange (XMI) provides real-time metadata exchanges and shared mechanism, and only an adapter is needed to correspond to accessing dynamically metadata of distributed software component, Experiments show the feasibility and validity of this architecture.
