title: .NET and Documentum 5.3 Integration
body: <p>I need to implement integration of a custom .NET application with Documentum 5.3. .NET application should provide functionality of managing folders, documents, metadata and search in configured Documentum 5.3.</p>
  
  <p>I've found the following integration options are available in Documentum 5.3:</p>
  
  <ul>
  <li>Documentum ADO.NET Services</li>
  <li>Documentum Foundation Classes (including PIA &amp; Web Services support)</li>
  <li>WDK</li>
  </ul>
  
  <p>I guess for .NET application preferable variant is DFC PIA. But here - <a href="http://forums.contology.com/index.php?showtopic=23639" rel="nofollow">http://forums.contology.com/index.php?showtopic=23639</a> - guys are discussing that DFC PIA is deprecated and will not be supported soon (I understand that it is sufficient for 5.3 - but I guess it'll require to overwrite the integration part if customer upgrades its Documentum).</p>
  
  <p>As for ADO.NET Services and "Web Services Framework for accessing Business Objects" - could you please provide more information to me - will I be able to perform tasks above (manage folders, documents, metadata, search) using these options? Could I access document content using ADO.NET Services or only document metadata?</p>
  
  <p>The final question is are there any other options I missed?
  And do you think the best option here is writing custom web service in java using DFC and then integrate .NET application with this web service? (approach similar to "Web Services Framework for accessing Business Objects" - but I'm not sure if this framework could provide all the abilities I need)</p>
