组件元数据生命周期需要一个全面的基础架构，该基础架构中的系统能够很好地协同工作。为了实现这种级别的合作，本文档提供了CMDI记录、组件及其XML表示形式的深入描述和定义。 本文档描述了这些XML表示，它们支持灵活构建适用于但不限于描述语言资源的可互操作元数据模式。基于这些表示的元数据模式可用于描述不同粒度级别的资源（例如，集合级别或单个资源级别的描述）。

The component metadata lifecycle needs a comprehensive infrastructure with systems that cooperate well together. To enable this level of cooperation this document provides in depth descriptions and definitions of what CMDI records, components and their representations in XML look like. This document describes these XML representations, which enable the flexible construction of interoperable metadata schemas suitable for, but not limited to, describing language resources. The metadata schemas based on these representations can be used to describe resources at different levels of granularity (e.g. descriptions on the collection level or on the level of individual resources).
