    Predicate Mapping by template in R2RML


      Is it possible to map predicate with template in R2RML? For example, I have a relational table with column call "RelationType". I want the value of the column to be the predicate, so I try something like below,


      rr:predicateMap [rr:template "http://example.org/{RelationType}"];


      Loading into staging table and create RDF view has no issue. But Query select ?s ?p ?o returns partial results with error saying, invlid RDF term syntax (value: null).


      I am wondering if ORCLE RDF view support this kind of mapping?
