Okay here's the complete detail on what we want to achieve.

 

After the user tries to upload their document using the ajax uploader, we will use Microsoft's DSOFile (http://suppot.micosoft.com/kb/224351) that let's you read document properties (Author, Title...etc) to check if the document/file properties has been filled out correctlly.

Our business rule requires that all documents uploaded must have their document properties filled out before uploading.
