Duo Qin, Lei Huang, Ying Wang · 2018
The large number of systems of the railway in China produced much complex and diverse data which are in various formats, scattered storage, and have a big difficulty in data sharing. Existing researches indicate that metadata management is useful to solve these problems. This paper by analyzing the types of metadata, makes a metadata content model and creates a standard for metadata standardization and exchange based on the CWM for the metadata of railway. Besides, we build the architecture and functions of the metadata system, and successfully designed a metadata management system which is beneficial to the data management for the railway systems.
