How space hierarchy is interpreted?
Lower (physical) levels are responsible for implementation of RA functionality used in higher (logical) levels where this functions are used to call BM functionality. Thus each level’s role is relative: it uses lower levels to represent and access BM of its own objects and implements RA functions for higher levels. Actually this hierarchy spreads down till the lowest levels of elementary physical interactions. The hierarchy can be similarly interpreted if each level implements relations for higher levels and on the other hand itself relies on relations implemented by lower levels. Here we use the principle ‘relations as objects at lower level’.
