Introduction

GB/T 26499 "Mechanical Science Data" is divided into four parts. 1) - Part 1. hierarchical classification method designed by the grading and classification machinery to regulate scientific data, in order to form a good machine Mechanical science data sharing mechanism to protect national security, public interests and the legitimate rights and interests of data producers, and promote scientific machinery The greater the value of the data and to play in a wide range of value-added applications. Part 2) 2. Data Element Directory, aims to mechanical properties of scientific data consistency and accuracy of the specification describes, Paul Data card with the same concept of meta semantically unified, standardized and unambiguous best to eliminate the confusion of data description. Part 3) 3. metadata, it aims to mechanical scientific data sources, content, quality, and use of a set of specifications and other information provided Description for researchers, and other users to provide relevant and efficient retrieval, access, use and evaluation services, and promote mechanical scientific data Preservation, management, communication, sharing and maintenance. 4) - Part 4. Interchange Format. It aims to establish machinery for scientific data sharing activities, structured and predefined data exchange Change the structure and format data in the collection, processing a plurality of links, remitted, distribution, services and applications like automatic switching, thereby Promote and facilitate the sharing of highly mechanical scientific data. Four parts mechanical science data standards were standardized four mechanical scientific data sharing management, it constitutes an organic whole Body, are indispensable. Entering the 21st century, in the new economic and technological conditions, support the machinery industry as an important part of national economic development, more and more social Attention will all walks of life, become popular in the field of scientific research. Machinery industry research process requires a lot of scientific data as a support, only Reliable, accurate scientific data systems in order to meet the needs of scientific and technological progress and technological innovation. However, in fact, the machinery industry research on subjects The use of school data is not ideal, the main reason for this phenomenon is that the scientific data have not been widely shared, so that although a large number of Data exist, but it is difficult to obtain, difficult to dig, this situation greatly hampered the machinery industry, as well as the development of science and technology and the economy. Metadata irregularities and the lack of uniform standards is the main reason for restricting the sharing of scientific data, so the establishment of a unified, standardized metadata standard Quasi share of great significance for the promotion and strengthening of data management data specification. --- Unified, standardized metadata standards can clearly describe the data production unit of data classification, data content, data quality, and Data management information; --- Unified, metadata standards can help data producers effectively manage and maintain data, a data document, ensure machine Investment structure of the data even if the personnel changes or loss of time from happening, it will not cause the loss of data files; --- Unified, standardized metadata standards can provide online data query, retrieval and exchange service for users, and user-friendly collection Information processing resources required. This section draws on data relevant metadata standards at home and abroad, and developed according to the characteristics of China's machinery industry scientific data, the number of mechanical science According metadata content standards. The enactment of this section will provide researchers, users and other relevant and efficient retrieval, access, use and evaluate services to promote the number of mechanical science According to the preservation, management, communication, sharing and maintenance. Mechanical Science Data Part 3. Metadata

1 Scope

This section GB/T 26499 specifies the content metadata mechanical scientific data, including resource collection metadata content and resource objects Metadata content. This section applies to cataloging the machinery industry scientific data, describe, manage and share. By using metadata standard specifications for use Households provided data retrieval services, dynamic data directory services, dynamic resource of relevant information services for data sharing and mechanical engineering Science data producers, data managers, data users and all stakeholders to help. Principles of this section may be extended to other areas of science Metadata standards and applications to go.
