sealed abstract class RelationExp extends AnyRef

binary relations between paths, i.e., relation in the MMT ontology

The semantics of a RelationExp is a binary relation on Paths with the usual operations for the calculus of binary endorelations. For example,

val relstore:RelStore
val doc: DPath
val deps = relstore.querySet(doc, +Declares * HasType(IsTheory) * (Imports | Reflexive) * -Declares)

could be used as a dependency relation between documents.
