- All terms in one concept record must be exact equivalents
of the descriptor, and also exact equivalents of each other
- Except for lexical variation and historical usage, all terms
should be interchangeable with each other
- This applies to terms in English and also terms in other
language, which must have cross-language equivalence
- That means terms in French or Chinese should have
the same meaning as the English record-preferred descriptor
