Table E.1 presents some of the EDCS dictionary entry fields for EDCS organizational schema. The contents of these fields are defined in Table 8.5. The EDCS dictionary entries are grouped alphabetically first by the EOL and then by the EGL. The EO is then not repeated for each of its EGs and instead the presentation of the EOL field is grey. The group label, reference type, reference, and supplemental references fields in the horizontal row that contains each EOL are presented in grey because these fields do not apply to the EO.
