The IETF (Internet Engineering Task Force) is the international community of network experts who have been designing the main Internet “standards” for the past 30 years or so. These include such landmark standards as RFC822 (email) and RFCs2045-2047 (MIME). New standards continue to be published and implemented today.
Two IETF contributions may be especially helpful for our current issues at work in transferring data between two isolated systems. For the published IETF documents, see:

Of special note: RFC1149 has been implemented in Bergen, Norway: http://www.blug.linux.no/rfc1149/
