Btw, i get validation error on zf2 from an online validator:

 All properties specified in XMP form shall use either the predefined schemas defined in the XMP Specification, ISO 19005-1 or this part of ISO 19005, or any extension schemas that comply with 6.6.2.3.2.   
 XMPProperty

Seems like metadata isr wrong.

Hi Paul,   
  
Thank you for contacting Syncfusion support.   
  
is there any plans to make ZUGFeRD 2.1.1 available for creation?   
At present we do not have any immediate plans to implement this feature. We usually have an interval of at least three months between releases and at the planning stage for every release cycle, we review all open features. We will consider this feature and update the details once it is implemented. The status of the implementation can be tracked through our Feature Management System,  
  
Btw, i get validation error on zf2 from an online validator:

We have analyzed the reported issue “ZUGFeRD validation failed while generated ZUGFeRD PDF document” and we did not face any issue related to XMP metadata in Adobe Acrobat preflight. Could you please share us the below details, so that it will helpful for us to provide the precise solution on this.   
  
  • Online validator link
  • Code snippet /Sample
  • Output document

Hello Sowmiya,
thank you for your fast answer.

  • Online validator link:
https://www.zugferd-community.net/de/dashboard/validation
  • Code snippet /Sample:
            PdfDocument document = new PdfDocument(PdfConformanceLevel.Pdf_A3B);
            document.ZugferdVersion = ZugferdVersion.ZugferdVersion2_0;
            document.ZugferdConformanceLevel = ZugferdConformanceLevel.Minimum;
            document.Compression = PdfCompressionLevel.Best;

            document.PageSettings.SetMargins(1);

            foreach (PdfTemplate temp in templateList)
            {
                PdfPage page = document.Pages.Add();
                PdfGraphics graphics = page.Graphics;
                graphics.DrawPdfTemplate(temp, PointF.Empty, new SizeF(page.Size.Width, page.Size.Height));
            }
            for (int i = 0; i < annotationList.Count; i++)
            {
                foreach (PdfLoadedAnnotation ant in annotationList[i])
                {
                    document.Pages[i].Annotations.Add(ant);

Hi Paul, 

Thank you for your patience. 
    
We have tried to reproduce the reported issue on our end, but it is working properly. We have created a sample with the provided code snippet and ensured the XMP metadata in Adobe Acrobat preflight and online validator, it passes the compliance. We suspect that the issue occurs only in a particular input document. We were not able to reproduce the issue on our end and we have shared the sample and output document for your reference. Kindly please run the sample on your end and let us know the result.   
  
 
Please refer to this below link for more information, 
 
If still, you are facing the same issue, kindly provide more details such as input XML file, modified sample, and product version to reproduce the issue on our end. So, that it will be helpful for us to analyze and assist you further on this.

I can confirm the loss of XMP-data:

By adding an existing pdf to an ZUGFeRD-pdf the XMP-data is lost (besides the pdfA3-confomance which can be restored by .ConvertToPDFA(..)):

       public void BuildZugferdPdf(Stream pdfZugferdOutStream, Stream pdfBillA3Stream, Stream xmlZugferdStream)
        {
            var zugferdPdf = new PdfDocument(PdfConformanceLevel.Pdf_A3B)
            {
                ZugferdVersion = ZugferdVersion.ZugferdVersion2_1,
                ZugferdConformanceLevel = ZugferdConformanceLevel.EN16931,
                Compression = PdfCompressionLevel.Best
            };

            var attachment = new PdfAttachment("ZUGFeRD-invoice.xml", xmlZugferdStream)
            {
                Relationship = PdfAttachmentRelationship.Alternative,
                ModificationDate = DateTime.Now,
                Description = "zugferd-invoice",
                MimeType = "application/xml"
            };
            zugferdPdf.Attachments.Add(attachment);

// this looses conformance and XMP-data:
            var pdfBillA3 = new PdfLoadedDocument(pdfBillA3Stream);
            zugferdPdf.ImportPageRange(pdfBillA3, 0, pdfBillA3.Pages.Count - 1);

            var ms = new MemoryStream();  
            zugferdPdf.Save(ms);  
            zugferdPdf.Close();

            var loadedDocument = new PdfLoadedDocument(ms);
            loadedDocument.SubstituteFont += LoadedDocument_SubstituteFont;  
            loadedDocument.ConvertToPDFA(PdfConformanceLevel.Pdf_A3B);  
            loadedDocument.Save(pdfZugferdOutStream);  
            loadedDocument.Close();  
        }

Hi Gowthamraj,

XMP data is now available, but pdf-validation fails on https://www.pdf-online.com/osa/validate.aspx for ZUGFeRD-Version 2.0 and 2.1:


            var zugferdPdf = new PdfDocument(PdfConformanceLevel.Pdf_A3B)
            {
               ZugferdVersion = ZugferdVersion.ZugferdVersion2_1,   // ZugferdVersion1_0 passes
               ZugferdConformanceLevel = ZugferdConformanceLevel.Basic,
               Compression = PdfCompressionLevel.Normal
            };
            zugferdPdf.Save(pdfZugferdOutStream);  

Is ths a bug in the lib or in the validator?

Best regards
Manuel

Hi Gowthamraj,

This is probabely a problem with the ZUGFeRD-metadata, which seems not to conform with the PDF/A-standard:: 

Version 2.1:

Version 1.0:


The xml-data is not part of this test.
