Technologies to Support
• FTP
• SMTP with MIME
• Encryption (PGP) or ‘in the clear’
Constituencies
• Low Tech– Paper-based systems– Access to a Web Browser– DOS based translator - Quick ‘N Easy
• High(er) Tech– Integrated Admin systems– Unix, FTP support
Registration/Repository
• Institution Name
• Contact Information
• Current Status: Testing, Production etc.
• Sending, Receiving, Both?
Registration/Repository cont.
• Delivery method (FTP, email)
• Time of delivery
• Server Address (IP)
• Technical requirements (EOL character etc.)
Daily EDI Activities
• FTP to Northwest U. before 9 a.m.
