Is that the intent? So a column reference in a mapping cannot be "EMP.JOB", it must be "JOB"? > > Yes, in rr:column, rr:template etc only "JOB" should be allowed. But this is more tricky than I thought. I raised ISSUE-70 for this, we'll discuss and resolve it within the WG. > http://www.w3.org/2001/sw/rdb2rdf/track/issues/70 I clarified the wording and examples of Section 5 to make clearer that it is ok to have a query like this: SELECT EMP.EMPID, EMP.JOB FROM EMP but regardless, in an rr:column you'd still have to refer to JOB, not EMP.JOB. I take it that it addresses your comment above. If not, then please let me know. For now I'll mark ISSUE-70 as pending review. Best, Richard
