<xs:documentation>
Groups are used to document related data. They may contain subgroups or individual study items, and may also contain metadata which is applicable to all members of the group, and is subject to over-rides at the lower levels. Thus, metadata is inherited down the grouping structure. The purpose of groups is described using the attributes which summarize relationships along the dimensions of time, panel, geography, instrument and language. These attributes allow the purpose to be machine-actionable, while the group also includes an element for describing the purpose in human-readable format.

<xs:element name="ResourcePackage" type="ResourcePackageType">
<xs:annotation>

The Resource is a specialized type of Group which is intended to hold re-usable metadata such as Category Schemes, Variables, etc. It is placed in the Resource construct for the purposes of being included by reference in other Groups and StudyUnits which describe studies, but does not directly describe existing studies itself.

<xs:annotation>

The Resource Package is a specialized structure which is intended to hold reusable metadata such as Category Schemes, Variable Schemes, etc. These are placed in the Resource Package for the purpose of being included by reference in Groups and StudyUnits.
