Conventions Used in the Tables

The names of key variables are appended with two asterisks (**). Some data sets do not have a key.

Foreign key variable names are prepended with two carat characters (^^). Foreign key variable names reference, in brackets [ ], the name of the data set for which it is a foreign key.

Required fields are marked with an X between brackets [X]. Required fields are fields for which a non-nil and non-whitespace-only value must be supplied in any observation for that data set.

All data set names and column names are case sensitive. They must be specified exactly as shown.

Only the DefineDocument data set, which contains valid values for the FileOID and FileType variables, is needed to create a minimal, but valid, CDISC CRT-DDS-compliant XML document. This is based on the CDISC CRT-DDS standard, which is very flexible.
