本文件: -基于ISO/IEC 19944中的数据分类法，描述了用于云计算环境中数据相关策略和实践的结构化表达的框架； -根据数据子类别和分类，提供应用分类法处理数据的指南； -涵盖数据相关政策和实践的表达，包括但不限于数据地理位置、数据跨境流动、数据访问和数据可移植性、数据使用、数据管理和数据治理； -说明如何将该框架用于静态和过境数据的行为守则，包括跨境数据传输以及远程访问数据； -提供数据处理挑战的用例，即根据ISO/IEC 19944数据类别控制、访问和定位数据。本文档主要适用于云服务提供商、云服务客户（CSC）和云服务用户，但也适用于参与云服务中基于分类法的数据管理的法律、政策、技术或其他影响的任何个人或组织。

This document:
- describes a framework for the structured expression of data-related policies and practices in the cloud computing environment, based on the data taxonomy in ISO/IEC 19944;
- provides guidelines on application of the taxonomy for handling of data based on data subcategory and classification;
- covers expression of data-related policies and practices including, but not limited to data geolocation, cross border flow of data, data access and data portability, data use, data management, and data governance;
- describes how the framework can be used in codes of conduct for practices regarding data at rest and in transit, including cross border data transfer, as well as remote access to data;
- provides use cases for data handling challenges, i.e. control, access and location of data according to ISO/IEC 19944 data categories.
This document is applicable primarily to cloud service providers, cloud service customers (CSCs) and cloud service users, but also to any person or organization involved in legal, policy, technical or other implications of taxonomy-based data management in cloud services.
