支持柔性机制的元数据驱动模型的研究与应用

以软件体系结构为中心的构件化软件开发方法保证了大型复杂系统构造的稳定性，而稳定框架支撑下的柔性支持力度是维持一个软件系统生命力和活力的关键，通过对元数据驱动模型控制原理的分析，讨论了基于元数据的流程图控制方法对层次化体系架构中各个层交行为控制的柔性机制支持，给出了iCALL系统中基于该元数据驱动机制提供应用支撑层柔性支持的一种元数据标记规则和该规则映射下的具体元数据表示示例。

Research on and the application of the metadata-driven model supporting flexibility

While architecture-centered and component-based software development methodology ensures the stability for constructing large complex systems, the flexibility degree supported by the stable framework is critical to maintaining the vitality of such systems. Based on the analysis of the principles of the metadata-driven model, this paper discusses in detail the flexibility mechanism supported by the metadata-based flowchart control approach for the multi-layer behavior diversification control of layered architectures. Finally, a set of metadata tag rules for the supporting level of iCALL *R systems and an appropriate sample metadata file are established based on this principle.
