StudyUnitType (complexType)

Describes the study unit which encompasses specified data collection processes as well as their resultant data products. This includes all of it's associated documentation and metadata. A Study Unit corresponds to the "study" as described in a traditional codebook, although a codebook may relate to only a single data product from the study. Typically, a 2.* or earlier version can have its content marked up in DDI version 3.0 with a single study unit containing the bulk of the documentation and metadata. Multiple data products from the same "study" (typically separate DDI instances in 2.* and earlier) can be combined in a single 3.0 instance. (See "DDI 3.0 Documentation, Part 1: Basic Structures" for more detail regarding the mappings between 2.* and 3.0.)
