An additional side note on "Distribution". DDI does not have a
"distribution module". Distribution and access are supported by DDI
content generally from the following sets of metadata:
conceptualcomponent.xsd Concepts, Universe, Geography (structure,
location)
studyunit.xsd, group.xsd, physicalinstance.xsd Coverage (topical,
temporal, spatial)
datacollection.xsd QuestionScheme/QuestionItem
logicalproduct.xsd CategoryScheme, VariableScheme, NCubeScheme
physicalinstance.xsd Summary and Category Statistics
For physical distribution:
physicaldataproduct.xsd PhysicalStructureScheme, RecordLayoutScheme
physicalinstance.xsd provides location of the data file itself
