Resources may have multiple occurrences, as subjects, predicates and
objects. Regarding Kinds, for example for a given Subject, it SubjectKinds
will be the set of all Predicate attributes and Object values according
their occurrences in triples where there is that Subject (the set with
kinds attrs/values intersection is populated from source triples
correspondingly). Then aggregation is done for class / metaclass inference.

Maybe yes. I use the term metaclass to aggregate possible states of a given
class instance.
