conversion:null

Occurrences of conversion:null within enhancement parameters means that no triple should be asserted in the conversion results.

Used as a value for the predicates conversion:interpretation and conversion:source_identifier.

Appropriate conversion:null use

conversion:null should only appear as values in enhancement parameters; occurrence of conversion:null in conversion results is nonsensical.

Omit ov:csvCol, dcterms:isReferencedBy, or void:inDataset subject annotations

ov:csvCol is asserted, e.g.:

vivo2doi:thing_2 ov:csvRow "2"^^xsd:integer .

This can be omitted by specifying the following:

      conversion:enhance [
         ov:csvRow conversion:null;
      ];

Similar for:

      conversion:enhance [
         dcterms:isReferencedBy conversion:null;
      ];
      conversion:enhance [
         void:inDataset conversion:null;
      ];

Avoid dcterms:isReferencedBy and/or void:inDataset on each row

                     conversion:enhance [
                        dcterms:isReferencedBy conversion:null;
                     ];
                     conversion:enhance [
                        void:inDataset conversion:null;
                     ];
