Research on the Quality Evaluation of Standard Metadata for the Digital Construction of Civil Aircraft Assembly Process Specifications
[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.
