While design patterns such the Participant pattern can yield a similar effect without actually requiring metadata support, they are somewhat abstruse to use.
虽然像Participant模式这样的设计模式可能不真正需要元数据支持就能得到类似的结果，但是它们并不容易使用。
Metadata Centralization facilitates discovery and therefore relates to other patterns that rely on design-time awareness in order to be consistently applied.
元数据集中方便了服务发现，因此它关系到其他模式，为了实现模式应用一致性，在设计时就应考虑它。
