本文件确立了定义施工中使用的属性的规则，以及编写和维护这些属性的方法，以便在BIM流程之后，利益相关者之间进行自信、无缝的数字共享。 关于财产和财产组的定义，本文件规定: -属性定义和属性组作为属性列表； -所有提供属性的定义。 关于创作和维护过程，本文件提供: -申请人的定义和角色； -专家和专家委员会的定义和作用； -请求属性的定义； -专家属性的定义； -要求建立管理规则，通过属性和属性组的映射过程互连数据字典。 为应用本文件的方法，前提是: -为数据字典建立治理模型； -数据字典网络的框架。 提供互联数据字典的内容不在本文件的范围内。

This document establishes the rules for defining properties used in construction and a methodology for authoring and maintaining them, for a confident and seamless digital share among stakeholders following a BIM process. Regarding the definition of properties and groups of properties, this document provides: — definitions of properties and groups of properties as a list of attributes; — definitions of all the provided attributes. Regarding the authoring and maintaining process, this document provides: — definitions and roles of applicants; — definitions and roles of experts and the commission of experts; — definitions of request's attributes; — definitions of expert's attributes; — requirements to establish the management rules to interconnect data dictionaries through the mapping process for properties and groups of properties. To apply the methodology of this document, it is presupposed that the following are in place: — an established governance model for a data dictionary; — a framework for a network of data dictionaries. It is not in the scope of this document to provide the content of the interconnected data dictionaries.
