My guess is that there are so few business-oriented object models or standards that there is no way to design a diffing model of those domains.
Anyone doing work in this space?
The company went under because of accumulated technical debt and a business model that didn't make a lot of sense and I jumped ship to the company that was getting the contracts we weren't getting and he jumped ship a year later but at that point I had moved on to a real job (mostly) working on products for a single company, that had health insurance, etc.
