A metadata standard is a high level document that establishes a common way of structuring and understanding data, and includes principles and implementation issues for utilizing the standard. It helps to record their collections and processes and to structure this information, and can be used to validate data integrity and quality. Metadata standards improve the quality and interoperability of information across information technology platforms by increasing compatibility, improving the consistency and efficiency of information collection, and reducing redundancy. This article introduced the progress and features of metadata standards of clinical research, and aimed to promote the standardization of clinical research and scientific process of therapeutic evaluation.
