| [目的/意义]国内民用飞机装配工艺规范数字化建设相对国外缓慢，实践过程中存在很多阻滞。目前鲜有从数字化需求对标准元数据质量进行测评的研究，相关研究既能从内容层面对元数据描述提出建设性意见，提高标准信息资源的数字化质量，又能推进民用飞机装配工艺数字化进程，助力智能制造。[方法/过程]对工艺规范与标准信息资源概念进行对比，分析民用飞机装配工艺规范数字化及标准元数据进展；理清民用飞机装配工艺规范数字化需求，基于调整后的BruceHillmann测评指标确定了工艺规范数字化需求下的标准元数据质量测评方案；以国家军用标准全文服务系统为例，对标最新版国家《标准文献元数据》，分析元数据对标准内容的揭示程度与数字化需求之间的差距，提出建议。[局限]单案例研究，典型性和全面性仍有待验证。[结果/结论]分析民用飞机装配工艺规范数字化进展和需求发现：数字化质量亟待提高，面向航空工艺规范的元数据标准是学界及业界需要共同解决的问题；通过测评数据发现：在描述上，元数据类型划分针对性不强，内容描述粗粒度，具体对象需求数据分散化，图表数字化程度低。因此建议：建立行业工艺规范元数据标准，提升工艺规范数据描述精度，以对象为中心推进工艺规范数据模块化，协调标准界、数据库商、业界共同推进工艺规范制定与同步数字化。 |

| [Objective/Significance] The digital construction of domestic civil aircraft assembly process specification is relatively slow, and there are a lot of hindrances in the process of practice.At present, the research of measuring the quality of standard metadata from the digital demand is relatively lacking.Its analysis can not only put forward constructive opinions on the description of metadata from the content level to improve the digitized quality of the standard information resources, but also promote the digitization process of civil aircraft assembly process and assist the intelligent manufacturing. [Methods/Processes] Compare the concepts of process specification and standard information resources, analyze the progress of digitization of civil aircraft assembly process specification and standard metadata; clarify the digitization demand of civil aircraft assembly process specification, on the basis of the adjusted Bruce Hillmann assessment indicators, a programme for assessing the quality of standards metadata based on the digitization needs of process specifications was identified; using the national military standard full-text service system as an assessment case, benchmarking against the latest version of the national “Standard Literature Metadata”, analyzing the gaps between the degree of metadata revelation of standard content and digitization needs, and putting forward suggestions. [Limitations] Single case study, its typicality and comprehensiveness still need to be verified. [Results/Conclusions] Analysis of the progress and demand for digitization of civil aircraft assembly process specifications found that the quality of digitization needs to be improved urgently, and metadata standards for aviation process specifications is a problem that needs to be solved jointly by the academia and the industry; through the measurement data, it is found that in the description, the division of metadata categories is not targeted, the description of the content presents coarse-grained, the data of the specific object demand is diffused and the digitization of charts and diagrams is low, etc. Therefore, it is suggested that the establishment of industry process specification metadata standards, improve the accuracy requirements of process specification data description, promote the modularization of process specification data with the object as the center, and coordinate the industry, standardization community, and database vendors to jointly promote the formulation and synchronization of process specification and synchronous digitization. |
