Getting the dc:identifier #1

Hello Richard,

First of all, congratulations for this useful library.

I've succesully checked in items with your sword java client. But I have a questions:

How can I recover de dc:identifier field (dublin core). I mean, I need the following:
<record>
<header>
<identifier>oai:localhost:123456789/21</identifier>
...
</header>
<metadata>
<oai_dc:dc xmlns:oai_dc=".....">
<dc:title>Picnic at Hanging Rock</dc:title>
...
<dc:description>Misteriosa historia ¿basada en hechos reales?</dc:description>
...
<dc:identifier>http://hdl.handle.net/123456789/21&lt;/dc:identifier>
...
</oai_dc:dc>
</metadata>
</record>

I know it's dublin core field, but I need exactly that http://hdl.handle.net/123456789/21, or at least the 21.

Looking at the atom feed output obtained with:
Content content = client.getContent(resp.getLocation(),
"application/atom+xml;type=feed", null, auth);

content.getFeed().writeTo(System.out);

After inserting the item, the most similar i found is:
...
<entry>
<id>http://localhost:8080/xmlui/bitstream/123456789/21/2/testPDF.pdf&lt;/id>
<title type="text">Original Deposit http://localhost:8080/xmlui/bitstream/123456789/21/2/testPDF.pdf&lt;/title>
...
</entry>

<id>http://localhost:8080/xmlui/bitstream/123456789/21/3/sword-2012-11-13T20:49:59.original.xml&lt;/id>
<title type="text">Original Deposit http://localhost:8080/xmlui/bitstream/123456789/21/3/sword-2012-11-13T20:49:59.original.xml&lt;/title>
...
<content type="application/octet-stream" src="http://localhost:8080/xmlui/bitstream/123456789/21/3/sword-2012-11-13T20:49:59.original.xml" />
...
</entry>
...

Is there a way to obtain it more directly?

Thanks in advance!
