== Interoperability Specification == | |||
In all networks that combines information from different systems over business and technology borders the crucial thing is to get interoperability. And there is no other way to do this than creating specifications that adds the "common good practices" to make things speak the same language. The interoperability spec will be a moving target with constant elaboration to enable true interoperability between systems | |||
