judyni - For EPUBS
I don't see any of my custom columns in the embedded opf (content.opf), nor do I see 'Producer', although I do see contributor. I suspect only the metadata items defined by EPUB 2.0 are written to the EPUB.
Code:
<dc:contributor opf:role="bkp">calibre (1.37.0) [http://calibre-ebook.com]</dc:contributor>
But I do see all my custom columns in the metadata.opf file - if they have a value; if they're undefined then they are not there.
Ah-ha - according to the LoC that
role="bkp" in
contributor is Book Producer see ==>>

Are you implying that you get a chain of these contributor items ?
