True object identifiers are abstract, i.e., the user never gets to see them.
So you don't need a global mechanism and there is no reconciliation
problem. You have to think of them as for example the nodes in a graph. A
directed graph is a binary relation but how the nodes are exactly
represented is immaterial.
