title: Store metadata into Jackrabbit repository
body: <p>can anybody explain to me, how to proceed in following scenario ?</p>
  
  <ol>
  <li><p>receiving documents (MS docs, ODS, PDF)</p></li>
  <li><p>Dublic core metadata extraction via Apache Tika + content extraction via jackrabbit-content-extractors</p></li>
  <li><p><strong>using Jackrabbit to store documents (content) into repository together with their metadata</strong> ?</p></li>
  <li><p><strong>retrieving documents + metadata</strong> </p></li>
  </ol>
  
  <p>I'm interested in points 3 and 4 ...</p>
  
  <p>DETAILS:
  The application is processing documents interactively (some analysis - language detection, word count etc. + gather as many details possible - Dublin core + parsing the content/events handling) so that it returns results of the processing to the user and then the extracted content and metadata(extracted and custom user metadata) stores into JCR repository  </p>
  
  <p>Appreciate any helps, thank you</p>
