Introduction
GB/T 26499 "Mechanical Science Data" is divided into four parts.
Part 1. hierarchical classification method designed by the grading and classification machinery to regulate scientific data, in order to form a good mechanical engineering
Learn the value of data sharing mechanism to protect national security, public interests and the legitimate interests of data producers, and promote scientific data in machine
A wide range of applications and greater play value.
Part 2. Data Element Directory, aims to mechanical properties of scientific data consistency and accuracy of the specification describes, with a guarantee
Have the same concept of data element semantically unified, standardized and unambiguous best to eliminate the confusion of data description.
Part 3. Metadata designed by mechanical science data sources, content, quality, and use other information to provide a standardized description
Said, as researchers, and other users to provide relevant and efficient retrieval, access, use and evaluate services to promote preservation of mechanical scientific data management,
Exchange, share and maintain.
Part 4. Interchange Format. It aims to establish machinery for scientific data sharing activities, structured and predefined data switching node
Structure and format data in the collection, processing a plurality of links, remitted, distribution, services and applications like automatic exchange, so as to promote and facilitate machine
Highly armed shared scientific data.
Four parts mechanical science data standards were standardized four mechanical scientific data sharing management, it constitutes an organic whole
Body, are indispensable.
In recent years, the production machinery industry practice and scientific research in the field of mechanical science has accumulated a large amount of scientific data. But when
Mechanical data sharing activities, the absence of uniform standards, different data sets on the same field, related data sets in different fields
The same concept name, definition, expression data description format often inconsistent, seriously affecting the machinery of scientific data resources
Sharing process.
To ensure mechanical scientific data sharing and service must be in the range of data, semantic and syntactic three levels established by
Mechanical environment for the expression of specific description of scientific data and its associated data, primarily through the development of science in the field of mechanical data element directory standards
to fulfill. Data element is the basic unit of data, the data element standards is on the properties of the object consistency and accuracy standards, in order to
Will be in the cross-system process, by positioning, access and exchange, increase the availability and sharing of scientific data machine.
This part of the selected data elements characterized by their six major categories. personnel, organization, address, contact classes; the date, time, duration class; digital
Resource Description and identity class; Digital Resources Construction and Management; the relationship between digital asset class; digital asset class background. In order to facilitate access and search
Get data element, according to data meta tags and sequence data element name Alphabetical index compiled data element.
The enactment of this section, in order to achieve mechanical scientific data sharing provides a unified data element standards, promote and facilitate the mechanical scientific data
Integration and sharing.
