Subject: Re: Trading Partner Logical Identification based on EDIFACT orX12qualifiers


The repository should contain the TPPs, choreographies, etc,  At least for
long term relationships, this information should be combined into a TPA
between the two parties, which can also be kept in the repository.  The
information would be cached locally when the TPA is installed by the two
parties.  At installation time, the installation software could
authenticate the parties and otherwise validate the TPA information but
there should be no reason to incur the overhead of a query to the
repository on every message.

Note that authentication and nonrepudiation can be applied to the messages
locally, which give some protection against something changing after the
TPA is installed.

We might want to include the repository ID in the TPA so the run-time will
know where to go when it has to go there.

Subject:  Re: Trading Partner Logical Identification based on EDIFACT or

There must be something I'm missing here. Doesn't the repository contain
the TPP for the party plus message choreographies it finds acceptable
(ignoring for a second the factoring of thr two)? If the repository is
optional, where does an ebXML messaging service obtain this vital
ebXML-compliant info? Or does an ebXML message need to understand
several other flavors of this?

If that's the case, and we're not careful to establish over-the-wire
interoperability between ebXML messaging service implementations, remind
me again why we're bothering to do ebXML?

Or are you suggesting that Amazon doesn't need to be ebXML-compliant,
but ebXML providers need to interoperate with whatever they have? That
seems way outside the scope of ebXML, and into the land of vendor
support for multiple eBusiness protocols/frameworks.
