The table below contains a list of additional standard reserved fragments to use as a guide when naming variables in ADaM datasets. This list should be used in addition to the list of timing fragments defined in Variable Naming Fragments and the fragments defined in the TIG Appendix x, CDISC Variable-naming Fragments. It should be noted that some concepts have slightly different fragments in ADaM than in the SDTMIGTIG; the ADaM fragment takes precedence when creating an ADaM variable. When using fragments, the general rule is to use the fragment(s) that best conveys the meaning of the variable within the 8-character limit. This list of fragments is provided as a guideline, not as a requirement.
