2) Заметим, что автор, таким образом, отождествляет далее термины "характеристический (ассоциативный, стержневой) тип сущностей" и "тип характеристических (ассоциативных, стержневых) сущностей". Поэтому мы будем использовать обе эти группы терминов. – Прим. пер.
3) Имеются в виду измерения многомерного информационного пространства, поддерживаемого RM/T. – Прим. пер.
4) Здесь диграф – ориентированный граф (от англ. digraph=directed graph). – Прим. пер.
