---------------------------------------------------------

I have run into the same issue. Margus IIgner's suggestion is correct. But applying a fix exposes a side-effect.

Using PdfBox 1.8.8, I create a PDF/A-3B document from a PDF/A-1 one. Adding a title to a DublinCoreSchema, leads to a validation error. The issue is restricted to the XmpBox library. The AbstractStructureType.createTextType picks up the namespace prefix defined for the DublinCoreSchema (let's say the predefined one, "dc") instead of using "rdf" (XmpConstants.DEFAULT_RDF_PREFIX). The fix is straight forward, adding a method that allows a prefix argument and using it wherever a XmpConstants.LIST_NAME TextType is used.

Side-effect: the title element after the fix still fails validation. The dc:title, rdf:Alt, rdf:li must also include a xml:lang attribute. But the field created for rdf:li is of type AbstractSimpleProperty. Attributes for such fields are not writen into the stream by the XmpSerializer unlike atrributes for fields of type ArrayProperty. The XmpSerializer.fillElementWithAttributes method also seems to be ignoring the namespace entries for attributes. The method also includes an "else if" clause that does the exact same thing as the else clause.

Having applied the necessary changes to overcome this issue, a valid PDF/A-3 containing a DublinCoreSchema element of tyoe title can be generated (the tests pass too). How can I help you guys out?

>          Issue Type: Bug
>          Components: Preflight
>    Affects Versions: 1.8.8
>            Reporter: Marcus Ilgner

> Validating a PDF for A1 compatibility, I get an error:
> {quote}
> Error on MetaData, Title present in the document catalog dictionary can't be found in XMP information (Property is not defined)
> {quote}
> Yet when I look at the file, the property is defined as such:
> {code}
>       <dc:title>
>         <rdf:Alt>
>           <dc:li>Rechnung 14512-14-001</dc:li>
>         </rdf:Alt>
>       </dc:title>
> {code}
> The code that sets the title (in order to make sure it's the same as the one from the document information):
> {code}
>         DublinCoreSchema dublinCore = xmp.createAndAddDublinCoreSchema();
>         dublinCore.setTitle("x-default", docInfo.getTitle());
> {code}
> Setting the creator via DublinCoreSchema seems to work as it doesn't raise the error anymore after calling {code}dublinCore.addCreator(docInfo.getAuthor());{code}.
