The submitted data will go through a three-step review process before archived (Figure 1). The first step is the online validation during the metadata submission. In this step, both the structure and vocabulary of the metadata will be checked automatically. The second step is the manual review, namely, the expert review. In this step, the data administrator will double-check the metadata to ensure the accuracy of the information. The last step is the quality control for the sequence files. In this step, both the format and content of the files will be checked, and the quality of the files will be evaluated.
