Calibre puts entries into the metadata of an ePub's OPF.

For example:

<dc:contributor opf:file-as="calibre" opf:role="bkp">calibre (0.7.28) [http://calibre-ebook.com]</dc:contributor>

<meta content="2010-12-07T07:18:36.758000+00:00" name="calibre:timestamp"/>
<meta content="Pride and Prejudice" name="calibre:title_sort"/>

This is quite an old conversion so things might have been changed in 0.8. I usually edit out the <meta content ... > lines but keep the <dc:contributor ...>

Update: There's also an entry in the OPF's XML namespace section -

xmlns:calibre="http://calibre.kovidgoyal.net/2009/metadata"
