We are creating more and more references between resources, resource fragments and services. The creation of these references is very costly and often is essential for the interpretation of a resource. Therefore we need a proper mechanism to ensure that these references survive despite all the changes that happen (e.g. in repositories): Persistent Identifiers provide such a mechanism.
