Details

A summary file contains a number of "logical" tables which are partitioned into 11 types of data files; each file type contains a segment of containing the variables of one or more of the logical tables. Variables within a table are defined as a hierarchical structure where each may be contain one or more child variables.

This dataset enumerates the variables contained within each segment, so that the column names can be overlaid onto the data as headers.

This dataset also provides a mapping from each variable to the logical table to which it belongs. An value of HEAD indicates that the variable is part of the header and does not belong to a logical table.

The hierarchical structure of each table may be accessed via the PARENT_FIELD variable. This variable specifies the parent in the hierarchy, or is NA if it at the top level of the hierarchy.
