Introduction
Soil science data is widely used in agriculture, forestry, ecology, environmental protection and other fields, is an important strategic resource for scientific and technological innovation and economic development.
Due to the lack of standardized metadata description of the characteristics of soil science data such as content, quality, soil classification and data generation methods, data
Difficult to find, manage and use, it is difficult to give full play to its role in data sharing and interdisciplinary applications.
Metadata is data about the data, the main role, including the description and management of data, to provide data query and retrieval methods to help data
Change and transfer, is to achieve data standardization and data sharing, exchange and integration of one of the main means.
This standard is based on the domestic and international standards, according to the soil science data collection, management and use of the characteristics of the development, is the soil science data set
Metadata content standards. By providing a scalable, conceptual model for describing and archiving management data, the group of normalized metadata
Management, promotion of soil science data sharing and exchange, protection of intellectual property rights.
Soil Science Data Metadata
1 Scope
This standard defines the requirements, technical content, and conceptual models of soil science data metadata, specifying the minimum required for metadata application
Data element sets (core metadata), and rules and methods for selecting, extending, and developing metadata-specific standards for metadata.
This standard applies to the cataloging and description of soil science data sets, organization and management, and data services for data exchange websites.
