Method and device utilizing polymorphic data in E-commerce

A non-transitory memory with computer program instructions to be executed on an e-commerce routing hub that includes a processor, memory and at least one network adapter, the computer program instructions including:

• first logic adapted to run on the processor to receives a first request from a first computer to start a supplier service session with a service running on a second computer identified by a unique name that is not a routing address;
• second logic adapted to run on the processor that looks up the unique name in a directory and matches the unique name to a routing address;
• third logic adapted to run on the processor that sends an additional request to start the supplier service session via the network adapter to the second computer, whereby the first and second computers are able to engage in the supplier service session by communicating directly between themselves, without routing a message exchange through the e-commerce routing hub;
• fourth logic adapted to run on the processor that, responsive to first and second service session end messages from the first and second computers, matches the first and second service session end messages and records results of the session.

A method of conveying data during an e-commerce session with a polymorphic response, the method including:

• initiating a session with a first message from a first party application to a broker application and a second message from the broker application to a second party application;
• conducting the session between the first and second party applications;
• and
• during the session between the first and second party applications, exchanging an additional message including:
• a schema identifier for the additional message, resolvable in a context of a system identifier;
• and
• a polymorphic response including a message type and version that, in combination with the schema identifier, define one or more additional data elements of the message type and version.
