DDI Instance¶
DDIInstance is the top-level publication wrapper for any DDI document. All DDI content published as XML (with the exception of a Fragment intended for transmission) has DDIInstance as its top level structure. In addition to a citation and coverage statement for the instance, the DDIInstance can contain a Group, ResourcePackage, LocalHoldingPackage or StudyUnit.
