Changing the Zotero plugin mapping

I would like to make some small changes to how the Zotero import plugin maps data from the Zotero element set to Dublin Core. It seems pretty simple - I would like to map the Zotero 'Note' field to the Dublin Core 'Description' field.

I thought I would do this by editing the plugins\ZoteroImport\models\ZoteroImport\Improcess.php file (following the example of the other Zotero-Dublin Core mappings) but haven't been able to do this yet.

Suggestions/tips would be appreciated!
