Abstract: An electronic commerce protocol stack includes a connectivity layer that receives business data from a first entity. The business data indicates that the destination of the business data is a second entity. The protocol stack also includes a translation layer that receives the business data and that translates the business data as appropriate for the second entity using one or more translation rules. The protocol stack also includes a semantic routing layer that receives the translated business data, determines the semantic meaning of at least a portion of the business data using one or more semantics rules, determines one or more appropriate destinations for the business data based on the semantic meaning, and communicates the business data the determined destinations to the connectivity layer. The connectivity layer communicates the business data to the determined destinations.
