I don't get triples if using predicateMaps.
According to the spec this should be doable, if I understand well, but I have not seen an example in the wild yet.
Anyhow if I use them, they do not generate additional triples.
<ActivityMapping>
a rr:TriplesMap;
rr:logicalTable [ rr:tableName "activity" ];
rr:subjectMap [
rr:class org:FormalOrganization;
rr:termType rr:IRI
];
rr:predicateObjectMap [
rr:predicate rov:orgActivity;
rr:objectMap [
rr:termType rr:IRI
]
];
rr:predicateObjectMap [
rr:predicateMap
[
rr:termType rr:IRI
];
rr:objectMap [
rr:termType rr:IRI
]
];
.
