There is very little support for kepubs in the base calibre. The only things I can think of is to allow the viewer to open them and the server to send them with the extension "kepub.epub" to Kobo ereaders. The other support is via an optional plugin.

For the metadata plugboard to work for kepubs, a metadata writer plugin is needed. And ideally a metadata reader plugin to complete the function. It is not hard as it is basically sub-classing the epub code. The only different bit is the cover as that is specified in the OPF using an attribute that isn't used with epub2.

I know I did either the reader or writer sometime in the past, but I haven't released them. Or maybe I posted it in the extended driver thread. I'll try and finish them in the near future. I'll also discuss with Kovid whether they should be integrated into calibre or released as separate plugins. I have a feeling there was something I couldn't see how to do if they were separate, but I can't think of what it was.
