Hi Steve,
I agree with discussion group members that XML won't make much of a
difference in transmisson time,because XML means just a syntax/format
change.Adding information about the data itself (meta data) anyways flows
with conventional EDI as well, in terms of tags/codes.XML is a means to
provide easy and efficienct data processing capabilities.
Just an insight, how Internet EDI is different from conventional EDI is
summarized as below :
1.Traditional EDI :-* VAN based. Uses proprietary protocols.
Internet EDI :- Internet based. Uses TCP/IP protocol
2.Traditional EDI :-* Offline - Delay in delivery
Internet EDI :- Online - Instant delivery
3.Traditional EDI :-* Expensive if VAN is not local.May have invest in
ISDN,Dialup,Leased Line,etc. to reach the VAN network
Internet EDI :- Can be reached through normal Internet connection.
4.Traditional EDI :-* Billing is generally by character or transaction.
Internet EDI :- Flat monthly fee (based on pipe bandwidth or connect time).
5.Traditional EDI :-* EDI Softwares are not Platform independent. There has
to be a different version for installation on different OS e.g., Unix,
windows etc.
Internet EDI :- Platform independent
6.Traditional EDI :-* EDIFACT, ANSI X.12, TRADACOMS, etc are conventional
EDI standards
Internet EDI :- XML is Internet oriented. Other conventional EDI standards
can be easily wrapped in XML.
