MIL-STD-3014定义了用于武器系统任务级编程的数字数据文件格式。术语格式适用于文件中数据信息的组织和已批准数据类型的定义。本标准首先定义了一种分层或“嵌套”文件体系结构，它允许将广泛且开放的各种数据类型组合起来，并用于各种目的。其次，该标准得到了在线注册中心的支持，这些注册中心对一些常用数据元素使用的标准格式进行了编目和定义，对于这些数据元素，通用数据格式是有益的。第三，该标准由在线登记处支持，这些登记处对特定采集项目所需的独特数据类型进行编目和识别。作为一种独特的数据类型注册表，本标准支持使用定义为专有、分类或应用非常有限的数据类型。 注册中心用于识别此类数据类型，而无需对其进行定义，并防止不同应用程序为不同类型的数据选择相同标识符时造成的不确定性和混乱。最后，该标准得到了在线注册中心的支持，这些注册中心可以识别产生、传输或处理任务数据文件的组织和采办系统。本标准未对任务数据文件的内容、数据的准确性或其对任何特定武器系统的适用性提出要求。这些特征是生成数据并将其格式化以用于武器系统的组织实体的责任。

MIL-STD-3014 defines a format for digital data files used for mission-level programming of weapon systems. The term format applies to the organization of data information in the file and the definition of approved data types.This standard defines, first, a hierarchical or "nested" file architecture, which allows a broad and open-ended variety of data types to be combined and used for a variety of purposes.Second, this standard is supported by online registries that catalogue and define standard formats to be used for some common-use data elements, for which a common data format is of benefit.Third, this standard is supported by online registries that catalogue and identify unique data types required by specific acquisition programs. As a unique data type registry, this standard supports the use of data types whose definitions are proprietary, classified, or have very limited application. The registry serves to identify such data types without the need to define them, and prevents indeterminacy and confusion caused when different applications choose the same identifier for different types of data.Finally, this standard is supported by online registries that identify organizations and acquisition systems that produce, transfer, or act upon mission data files.This standard does not establish requirements for content of mission data files, accuracy of data, or its applicability for any specific weapon system. Those characteristics are the responsibility of the organizational entity that generates the data and formats it for use in a weapon system.
