复杂重型装备设计、工艺、制造、运维阶段元数据及数据字典

本数据集分别描述了复杂重型装备定制生产中设计、工艺、制造、运维四个阶段的元数据及相应的数据字典。主要从类名、属性名称、定义、数据类型、值域、约束/条件、最大出现次数七个数据项对数据集进行描述。其中，类名指的是元数据所属类别；属性名称指的是元数据的名称；定义指的是对元数据的具体解释；数据类型指的是元数据所属的数据类型；值域指的是元数据的可取值范围；约束/条件指的是不能为空，是必填字段，M即为Must的缩写；最大出现次数指的是在实体与实体之间关系中，该元数据可以出现的最大次数，有1次和N次两种取值。

This dataset describes the metadata and corresponding data dictionaries for the four stages of design, process planning, manufacturing, and operation & maintenance in the customized production of complex heavy-duty equipment. It primarily characterizes the dataset via seven data items: class name, attribute name, definition, data type, value range, constraint/condition, and maximum occurrence count. Specifically, the class name refers to the category that the metadata belongs to; the attribute name refers to the name of the metadata; the definition refers to the specific explanation of the metadata; the data type refers to the data type of the metadata; the value range refers to the range of allowable values of the metadata; the constraint/condition indicates that the field cannot be empty and is a required one, where M is the abbreviation for "Must"; the maximum occurrence count refers to the maximum number of times this metadata can appear in the inter-entity relationship, with two available values: 1 time and N times.
