Hi, Coming a bit late to the discussion, I'm not aware of any article on the matter, but from experience I have found that sharing surrogate keys across BCs is a bad idea. The reason is, such keys are internal details of the BC that you might decide to change at any point in time. If you have shared this key with other BCs then any change will have a lot of impacts. On the other hand, natural keys are business concepts that rarely change and when they do, they impact everything anyway.
