How does ebBP relate to BPSS?
Briefly and simply, ebBP is a short name, or alias, for the technical specification that realizes business collaboration, ebXML BPSS. They are one and the same. The objective is to define business processes in a standard way to allow interoperability between systems, organizations, business partners and collaborating parties. This will enable eBusiness. Labeling the latest and more substantive version ebBP focuses on the objective rather than the mechanism for achieving the objective which is the technical specification.
