see conversion:predicate.

Example 1

Input:

Alabama,Tobacco Price/Tax/Funding,Government,1991,State excise tax per pack,0.17,US Dollars,1990,1991
Alabama,Tobacco Price/Tax/Funding,Government,1991,Total cigarette tax per pack,0.345,US Dollars,1990,1991

Enhancement parameters:

<http://logd.tw.rpi.edu/source/twc-rpi-edu/dataset/iogds-upstream/version/2012-Jan-07/conversion/enhancement/1>
   a conversion:LayerDataset, void:Dataset;

   ...

   conversion:conversion_process [
      a conversion:EnhancementConversionProcess;
      conversion:enhancement_identifier "1";

      ...

      conversion:enhance [
         a conversion:SubjectAnnotation;
         conversion:predicate  dcterms:description;
         conversion:object     "This is an awesome description!";
      ];

The output will have a dcterms:description on each subject:

:thing_2 
   dcterms:isReferencedBy <http://logd.tw.rpi.edu/source/lebot/dataset/templated-subject-annotations/version/2012-Jul-12> ;
   void:inDataset <http://logd.tw.rpi.edu/source/lebot/dataset/templated-subject-annotations/version/2012-Jul-12> ;

   dcterms:description "This is an awesome description!" ;

   e1:state     "Alabama" ;
   e1:category   value_of_category:Tobacco_Price_Tax_Funding ;
   e1:entity     "Government" ;
   e1:start_year "1991" ;
   e1:measure    "State excise tax per pack" ;
   e1:value      "0.17" ;
   e1:unit       "US Dollars" ;
   e1:succeeds   "1990" ;
   e1:end_year   "1991" ;
   ov:csvRow "2"^^xsd:integer .

...

:thing_3
   dcterms:description "This is an awesome description!" ;

...

:thing_4
   dcterms:description "This is an awesome description!" ;

Example 2

The object string can include a [template](Using template variables to construct new values):

      conversion:enhance [
         a conversion:SubjectAnnotation;
         conversion:predicate  dcterms:description;
         conversion:object     "I love the great state of [#1]!";
      ];

that will include a cell value in the annotation:

:thing_2
   dcterms:description "I love the great state of Alabama!" ;

Example 3

If the object looks like a URI, it'll become one:

      conversion:enhance [
         a conversion:SubjectAnnotation;
         conversion:predicate  dcterms:description;
         conversion:object     "http://dbpedia.org/resource/[#1]";
      ];

@prefix dbpedia: <http://dbpedia.org/resource/> .

:thing_2 
   dcterms:description dbpedia:Alabama ;

Example 4

TODO:

      conversion:enhance [
         a conversion:SubjectAnnotation;
         conversion:predicate  "description";
         conversion:object     "http://dbpedia.org/resource/[#1]";
      ];

Example 5

Multiple objects is fine, too:

      conversion:enhance [
         a conversion:SubjectAnnotation;
         conversion:predicate  dcterms:description;
         conversion:object     "http://dbpedia.org/resource/[#1]", 
                               "[#4] was a great year.";
      ];

:thing_2
   dcterms:description "1991 was a great year." , dbpedia:Alabama ;

Example 6

      conversion:enhance [
         a conversion:SubjectAnnotation;
         conversion:predicate  "[#5]";
         conversion:object     "[#6]";
      ];

:thing_2
   e1:state_excise_tax_per_pack "0.17" ;

Example 7

      conversion:enhance [
         a conversion:SubjectAnnotation;
         conversion:predicate  "[#5]";
         conversion:object     "xsd:decimal([#6])";
      ];

:thing_3
   e1:total_cigarette_tax_per_pack "0.17"^^xsd:decimal ;

Historical note

Used to be (but was deprecated and replaced; no longer works):

ov:csvCol 0; 
conversion:predicate "p"; 
conversion:object "o"
