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 triples

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;
      ];
