Yes, each object knows its relationships.

Yes, similar to an rdb. To bootstrap, start with root, which is the ancestor parent/class of all objects, and traverse all system-defined and user-defined objects (classes, instances, properties, references, etc). You can simulate this by selecting the root and clicking the navigation buttons (ie Parent, Child, PrevSibling, NextSibling, Class, Instance, PrevSibOfSameCls, NextSibOfSameCls).
