conversion:object_label_property

a conversion:Enhancement.

When a URI is created from a literal, the converter annotates it with rdfs:label and dcterms:identifier. In the case where you need to use a re-invented label property that is not one of these, conversion:object_label_property is used to indicate additional label properties to assert (in addition to rdfs:label and dcterms:identifier).

So, the cell value:

Channel Morphology,Dam Removal,Erosional Systems,Stream Restoration

becomes

@prefix tag: <http://www.holygoat.co.uk/owl/redwood/0.1/tags/> .

<tag:cet.ncsa.uiuc.edu,2008:/tag#Desktop_Watersheds>
   dcterms:identifier "Desktop Watersheds" ;
   rdfs:label "Desktop Watersheds" .

with

      conversion:enhance [
         ov:csvCol    7;
         ov:csvHeader "all_keywords";
         conversion:eg                 "Channel Morphology,Dam Removal,Erosional Systems,Stream Restoration";
         conversion:delimits_object     ",\\s*";
         conversion:equivalent_property tag:taggedWithTag;
         conversion:range               rdfs:Resource;
         conversion:range_template     "tag:cet.ncsa.uiuc.edu,2008:/tag#[>.<]";
         conversion:range_name         "Tag";
      ];

adding conversion:object_label_property tag:name; to the above will result in:
