stdyInfo specific child nodes

• ddi_abstract() is an unformatted summary describing the purpose, nature, and scope of the data collection, special characteristics of its contents, major subject areas covered, and what questions the PIs attempted to answer when they conducted the study. A listing of major variables in the study is important here. In cases where a codebook contains more than one abstract (for example, one might be supplied by the data producer and another prepared by the data archive where the data are deposited), the "source" and "date" attributes may be used to distinguish the abstract versions. Maps to Dublin Core Description element. Inclusion of this element in the codebook is recommended. The "date" attribute should follow ISO convention of YYYY-MM-DD.

• ddi_studyBudget()is used to describe the budget of the project in as much detail as needed.

Value

A ddi_node object.
