       Metadata Scoring Plugin
     </p>
     <p>
       Propagates Metadata from an injected or outlink url in the crawldb to the url's different procecssed objects. In moving any metadata item, you need to copy metadata in three steps:
     <ul>
       <li>Crawldb to content: Copy a metadata entry stored in the crawldb record of the url to the url's fetched content object. You need to specify the entry in the <b>scoring.db.md</b> property</li>
       <li>Content to parsedData: Copy a metadata entry stored in the Content object of a crawled url to its parsedData.  You need to specify the entry in the <b>scoring.content.md</b> property</li>
       <li>ParsedData to outlink objects: Copy a metadata entry stored in the parsedData of a crawl item to the crawldb records of the url's outlinks. You need to specify the entry in the <b>scoring.parse.md</b> property</li>
     </ul>

     Note that you can not move data directly from a crawldb record to parseData or outlink objects. The sequence of moving the metadata should be crawldb -> content -> parsedData -> outlink objects.
