4.0 术语组件

4.0.1 介绍

术语组件提供了FHIR资源、操作、编码数据类型和外部定义的标准以及FHIR定义的术语的概述和指南，这些术语用于表示和解释FHIR核心规范和配置中的编码结构化数据。 总的来说，上述能力用于提供功能性术语服务，以支持在整个规范中使用FHIR资源中的编码数据，在FHIR规范的其他组件也会对其有所描述。

术语相关体系结构及其组成关系如下所示：

此图展示术语资源及其相互关系

上图使用的例子：对诊断进行配置，将其中的Condition.code 切片绑定到“SNOMED CT 骨折编码”值集。

[注：ElementDefinition类型（用虚线框展示部分）将在本规范别处另行介绍,详见 基础组件 and 符合性组件]

4.0.5 开发路线图

The following terminology resources have been tested and are being used in production tooling and now are normative or are expected soon to progress to normative.

Other terminology resources are still in earlier stages of development. We intend to continue to develop and test these resources and advance them through the Maturity Levels at Connectathons and elsewhere.
