Minutes from the EDIINT WG Session at the IETF December 1997 Meeting

Rik Drummond, WG Chair, and Dale Moberg, Editor for the Secure EDI over 
HTTP Applicability Statement Draft, made presentations during the meeting.

Rik Drummond welcomed everyone and reviewed the WG status. Approximately 
20% of the 30 attendees had read the three WG Drafts.  We will submit the 
first two drafts to the Experimental RFC track as a holding action until 
the S/MIME issue is resolved one way or the other, since both drafts 
reference S/MIME.  There are three Internet Drafts now available.  A 
fourth, specific to the healthcare industry (HL7), is expected in January. 
The current drafts are: Requirements, Applicability Statement for Secure 
EDI over SMTP, and Applicability Statement for Secure EDI over HTTP.

Rik noted that Microsoft Exchange is still causing problems because or the 
way MIME / MAPI translations take place. It is not know if Exchange version 
5.5 fixes the problem.

Dale Moberg presented the status of the Secure EDI over HTTP Draft.  It 
follows closely the SMTP Draft, making only changes necessary to convert 
the SMTP-based recommendations to the HTTP protocol.  Dale noted that one 
of the problems he found in a test implementation of Secure EDI over HTTP 
is that the servers timeout if the response takes to long. Einar Stefferud 
noted that maybe this makes the HTTP protocol inappropriate for this 
application and we should look for other transport technologies.

Several general comments were made during the meeting:

Keith Moore commented that we could modify the MDN and make it specific to 
EDI usage. This may help us in the definition of the MDN for the Healthcare 
HL7 Draft. This would allow a single message that contains the signed 
receipt and the transaction response data to be returned in response to an 
HL7 transaction.

Einar Stefferud noted that Content-ID was available as a MIME level header 
for identifying separate MIME parts for use in more complex receipts.

Finally we discussed the possible need for time-stamping of EDI 
transactions.
