I am a new comer to this group. Can anyone kindly point to me some useful sources to study how XML influences the development of Internet EDI? In various places, I see mentioning that EDI is dead because of the proliferation of XML. I don't understand this. Conventional EDI requires translators to integrate with backend applications. XML will not do away with this, but will perhaps make it easier for organizations to write their own translators.
Is XML a hype or really a catalyst for next generation of EDI?

GISB has been using PGP to encrypt and sign EDI data since 1997 so this will
remain their "crypto" standard. GISB REQUIRES the use of RSA public key
algorithms to process EDI data. RSA algorithms are supported in PGP.
The GISB/AS2 interoperability profile packages "PGP processed" data inside a
multipart/signed or multipart/encrypted MIME envelope, in accordance with
AS2 specifications. The entire multipart/* MIME envelope and encrypted data
is then placed inside a multipart/form-data package. Here is what the entire
package looks like when it's all put together (indention used to indicate
Content-Type: multipart/form-data; boundary="foo"
message headers are packaged here (To=XXX, From=YYY, etc.)
Content-Type: multipart/encrypted; boundary="foo2";
Content-Type: application/EDI-X12 (signed/encrypted using PGP)
ISA*.....X12 data (signed/encrypted using PGP)
With regard to an earlier reference to the AS1 packaging style within AS2; I
believe the new AS2-To and AS2-From header fields are incompatible with AS1
so we might want to refer to this "new packaging style" as the AS2/email
packaging style in the next version of the AS2 spec and remove references to
AS1. Would you agree?
