ESG Appendix G: AS2 Header Attributes

{Previous Appendix} {Table of Contents} {Next Appendix}



In order to communicate the filename to the FDA, the FDA requires the FileName Preserve on all AS2 submissions. In addition to tarring/gzipping the actual documents, AS2 submissions must include the following attributes in their AS2 headers. The additional information is comprised of:

  • FDA submissions Type
    • FdaSubmissionType: Abbreviated New Drug (add submission type information)
  • Center Name-
    • FdaCenter: CDER (add Center information)

    The Mime Headers are to be located in the outermost MIME wrapper and will appear as follows:

    • X-Cyclone-Metadata-FdaSubmissionType: ENDA
    • X-Cyclone-Metadata-FdaCenter: CDER

    The following example represents how the standard AS2 mime header should appear after appending the Center and SubmissionType attributes and upon and presented at the FDA ESG.
