It's not incompetency just incomplete knowledge of PDF. Since PDF
1.4 (Acrobat 5), Adobe has moved away from the classic "DocInfo" type
of metadata to an XML-based metadata called XMP - though PDF/A was the
first subset of PDF to REQUIRE XMP.
So what you need to do is read up on XMP and then update your
software. iText supports XMP.

Hi all
I use iText for extract PDF text and PDF-file metadata.
In last case code is simple
PdfReader reader = new PdfReader(is,"".getBytes());
//Read the file metadata
HashMap info = reader.getInfo();
reader.close();
String author = (String)info.get("Author");
//etc.
It works well with ordinary pdf-files. But returns nothing from PDF/A.
-Is there a bug, or my incompetency?
-How can I read metadata from PDF/A?
- If there no any solution, recommend me another tool for read pdf
(PdfBox nice, but there is a problem with metadata extraction too).
Thanks
