Drawing from my inter-industry standardization experiences then it seems
unlikely that there will be a common ontology in the domain of international
commerce.
One simple reason is that different legal systems require different conformance
for enterprise within their jurisdiction. (03)
On the other hand, most industries start out by saying that they have different
requirements but after a while , the "shared" percentage starts growing
significantly. And patterns of Variablity aspects start appearing. Some aspects
are similar and some different. Commerce has established a set of agreed
patterns over the year, some even agreed to by UNIDROIT, UN/CITRAL etc. (04)
Managing Variablity is IMHO a useful modeling practice. As well as managing
conflicts and disagreements. (05)

Im not sure neutral is the quality to look for. Neutrality is often ascribed to
the caretaker of an ontology, and interoperabilty includes a process of
agreeing in order to reduce risk and costs for involved parties. (07)
