Hi Ajeeb,


Thanks for your inquiry. I am afraid currently Aspose.Pdf does not support metadata namespace with prefix. However we have logged a new feature request as PDFNEWNET-36439 in our issue tracking system for further investigation and implementation. We will notify you via this forum thread as soon it is implemented.

We are sorry for the inconvenience caused.

Best Regards,

Hi Ajeeb,


Thanks for your patience. We have further investigated the issue and found that you should use namespace name without prefix. Please
take a look on following code snippet. Hopefully it will help you to accomplish the requirements.


pdfDocument.Metadata.RegisterNamespaceUri(“xmp”,“http://ns.adobe.com/xap/1.0/”);
// xmlns prefix removed<o:p></o:p>

pdfDocument.Metadata[“xmp:ModifyDate”] = DateTime.Now;<o:p></o:p>

Please feel free to contact us for any further assistance.


Best Regards,

Hi Ajeeb,

Thanks for contacting support.

I am afraid currently Aspose.Pdf for .NET does not support the feature to convert PDF file to PDF/A-3 format. For the sake of implementation, I have logged this requirement as PDFNEWNET-36686 in our issue tracking system.
