2. How those data are copied to an .epub by convert/polish->update metada is another question.
There, I would like as well to delete the user information, AFTER having employed some of my <meta name="calibre:user_metadata:#customized"... . For instance:
<meta name="calibre:user_metadata:#ordate"...content... &quot;__value__&quot;: &quot{date}&quot; -> <dc:date opf:event="creation">{date}</dc:date>
I suspect this would require a plug-in, but I don't know where to begin--a template to get started?
My fault: (1) was about metadata.opf. (2) Is what I would wish done (automatically) to the .opf file in the epub: doing it (and more) by hand every time.
