Why do the metadata files I am trying to submit fail to validate?

Submitted by Anonymous on

The GDC Data Submission Portal checks XML, JSON, and TSV metadata files for validity at the time they are submitted. If your files fail to validate, please check the error report and review the GDC Data Dictionary for troubleshooting these errors. Additional information on supported files and formats can be found on the GDC Data Model and File Formats pages, and in the GDC Data Submission Portal User's Guide.
