A metadata standard construction method based on intelligent mine data classification and coding standards

Abstract

Currently, the construction of intelligent mines is facing problems such as incomplete data standards, difficulty in integrating heterogeneous data from multiple sources, and the need to improve sharing mechanisms. Establishing a unified intelligent mine metadata standard is of great significance for forming a multi-source heterogeneous data fusion and sharing mechanism. Based on the intelligent mine data classification and coding standards, the construction method of intelligent mine metadata standards is studied. It is clarified that metadata standard construction is an extended research and value mining of data classification and coding. This paper defines the connotations of metadata entities and metadata attributes. This paper designs an intelligent mine metadata description framework that includes a basic description framework and an extended description framework. This paper provides basic metadata attribute description items that reflect the features of intelligent mine business scenarios, as well as extended metadata attribute description items for the four major thematic domain groups of basic, production, safety, and management in the intelligent mine data classification and coding standards, thus forming a metadata standard. Taking the inertial sensor of the shearer inertial navigation system in the production theme domain group as an example, the construction process of metadata standards is introduced. Building metadata standards based on intelligent mine data classification and coding standards can solve the problem of fusion and sharing of multi-source heterogeneous data, promote mine enterprises to manage, analyze, and apply data more efficiently, and improve the intelligence level of mine data governance.
