Libraries based on linked data cataloging will provide strong data support for the transformation of digital libraries to smart libraries, and will effectively improve the visibility and usefulness of libraries in the network environment. This paper focuses on sorting out the main content of the international cataloguing standard system, especially summarizing the development and evolution characteristics and development laws in recent ten years, in order to provide useful reference for the research on resource cataloging standards and the practice of datafication for China.
