ISO 19778-2:2015规定了协作环境的数据模型。 协作环境数据模型由协作工具组成，并通过指定它们的名称来声明它们的协作功能。这些名称可用作进一步规范或标准详细规定的协作工具和协作功能的参考。如果没有或未确定此类规范或标准，则提供人类解释说明可能有助于协调使用这些名称。

ISO 19778-2:2015 specifies the Data Model for a collaborative environment. The collaborative environment Data Model composes collaborative tools and declares their collaborative functions by specifying their names. These names can be used as references to collaborative tools and collaborative functions specified in detail by further specifications or standards. Where no such specifications or standards are available or identified, the provision of descriptions for human interpretation may support harmonized use of these names.
