Information that is housed in the EF will come from various case processing systems
            used by SSA and DDS offices to process disability case. Information from external
            sources (e.g., medical providers, claimants, representative, third parties, etc.)
            will also be added to the EF. The EF will consist of information that is keyed into
            data entry fields and images of documents that have been scanned/ faxed and electronic
            forms that have been uploaded to the EF as images.
