Hello.

 

I'm very pleased that iText have started to support PDF/A.

 

By the way, I found a small point to improve compatibility to PDF/A.

 

PDF/A forces that the info dictionary of PDF have to match with the XMP metadata embedded to PDF.

 

But, the subject of info dictionary of PDF must match with the dc:description of XMP metadata.

 

 

If you handle info dictionary directly, you will have to change the constructor of XmpWriter that has a stream and a hashtable for input in XmpWriter class,

 

you can add a line to match subject of hashtable with dc:description of XMP metadata as followings; ( following codes are for iTextSharp.)

 

         public XmpWriter(Stream os, Hashtable info) : this(os) {
            if (info != null) {
                DublinCoreSchema dc = new DublinCoreSchema();
                PdfSchema p = new PdfSchema();
                XmpBasicSchema basic = new XmpBasicSchema();
                String value;
                foreach (DictionaryEntry entry in info) {
                    String key = (String)entry.Key;
                    value = (String)entry.Value;
                    if (value == null)
                        continue;
                    if ("Title".Equals(key)) {
                        dc.AddTitle(value);
                    }
                    if ("Author".Equals(key)) {
                        dc.AddAuthor(value);
                    }
                    if ("Subject".Equals(key)) {
                       dc.AddSubject(value);
                       dc.AddDescription (value);      //add to comply with PDF/A-1
                    }
                    if ("Keywords".Equals(key)) {
                        p.AddKeywords(value);

 

                    ...
