    Merging annotations in PDF using Assembler Service

      Hi all,

       

      I want to merge Annotations in pdf. For that, I am using Assembler service. DDx is as below:

       

      <DDX xmlns="http://ns.adobe.com/DDX/1.0/">

        <PDF result="resultDoc">

          <PDF source="originalPDF"/>

          <Comments source="commentsXFDF"/>

        </PDF>

        <?ddx-source-hint name="originalPDF"?>

        <?ddx-source-hint name="commentsXFDF"?>

      </DDX>

       

      Above DDX is not working for pdfs, which are not created by Adobe(related products).  Sample Input pdf producer is "Dalim Software Applications"

       

      Error logs are as below:

       

      2013-10-01 00:14:21,675 WARN  [com.adobe.internal.ddxm.ddx.pdf.PDFResult] (http-0.0.0.0-8080-4) DDXM_W10001: Could not update metadata on resultDoc.pdf.

      I tried to validate metadata of the input pdf using http://www.pdflib.com/knowledge-base/xmp-metadata/free-xmp-validator/,  and the result is as follows:

       

      XMP data is  invalid

      Reason: XMP metadata: Description of extended property 'xmpMM:OriginalDocumentID' missing in embedded extension schema 'xmpMM' description

       

       

      Now, if actual cause of the issue is invalid xmp data, then How can I deal this types of pdfs.

       

      Is there any tool to repair xmp data or any thrid party library to merge all types of annotations (like text comments, stamps, file attachments , ..)  in pdf.

       

      Please suggest
