Let me clarify

The following mapping is correct:

<TriplesMap1>
    a rr:TriplesMap;
    rr:logicalTable [ rr:tableName "Employees" ];
 rr:subjectMap [ rr:column "FirstName"; rr:termType rr:BlankNode ];
rr:predicateObjectMap
    [
      rr:predicate foaf:name;
      rr:objectMap    [ rr:column "FirstName" ]
    ]
    .

The following mapping should fail:

<TriplesMap1>
    a rr:TriplesMap;
    rr:logicalTable [ rr:tableName "Employees" ];
rr:subjectMap [ rr:column "FirstName" ];
 rr:predicateObjectMap
    [
      rr:predicate foaf:name;
      rr:objectMap    [ rr:column "FirstName" ]
    ]
    .

right?
