Shift the context against an arc. Shift from the set of resources, along each predicates, filter the results with the filter The predicates get evaluated with the shifted context The filter is applied to each result set with the resource that created it as context

Optimization for traversals where the predicate does not change in any of the possibilities

Base class for all Traversals

http://www.w3.org/TR/rdf-mt/#RDFRules (7.3 RDFS Entailment Rules) OWL usage of rdfs:domain, rdfs:range, and Extensional Entailment Rules *could* provide some optimizations via inference, when evaluating traversal expressions, they could also implement *some* RDFS entailment rules by providing additional checks when evaluating traversals.
