规范概念
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
如开发者指南中所述，数据集可以引用其他数据集中定义的概念。尤其是 Google，已经创建了一组适用于各种用例的“规范概念”数据集。除了享受上述好处外，您还可以获得以下好处：
- 控制数据的可视化方式（例如颜色、单位等）
- 指定数据注解
- 以一致的方式定义时间点
- 使概念可映射
- 在使用常见的地理概念（例如，国家/地区）
下表汇总了这些数据集：

注意：此处记录的某些规范概念（目前）在 Public Data Explorer 中不可见。如需了解详情，请参阅此常见问题解答内容。
概念关系图
下图总结了已记录的规范概念。每个节点代表一个概念（按数据集进行颜色编码），而概念之间的箭头表示继承关系（例如，quantity:count 扩展了 quantity:quantity）。点击图中的节点即可转到相应概念的文档。
