com.bigdata.rdf.rules
Class RuleRdfs03

java.lang.Object
  com.bigdata.relation.rule.Rule
      com.bigdata.rdf.rules.RuleRdfs03

All Implemented Interfaces:

IRule, IStep, Serializable

public class RuleRdfs03
extends Rule

rdfs3:

    triple(v rdf:type x) :-
       triple(a rdfs:range x),
       triple(u a v).
 

Note: Literals can be entailed in the subject position by this rule and MUST be explicitly filtered out. That task is handled by the DoNotAddFilter. RuleRdfs04b is the other way that literals can be entailed into the subject position.
