The Resource Package is a specialized structure which is intended to hold reusable metadata outside of the structures of a single StudyUnit or Group. This may be common methodological approaches bound in a DataCollection module, DataRelationship information bound in a LogicalProduct, or any maintainable scheme. The ResourcePackage is often used to manage and publish metadata that is used by StudyUnits or Groups by reference. Any maintainable object with the exception of a Group, StudyUnit or LocalHoldingPackage may be published in a Resource Package.
