I use this plugin to fix up the metadata on kepub books downloaded from Kobo. What I do is download the plain epub version and add it to Calibre, then connect my Glo so that the epub in Calibre is matched to the kepub on the device, then edit the epub's metadata and use the plugin to update the device. It has been working great, saves a lot of time compared to editing the database manually.

I also have a metadata plugboard in Calibre which transforms the authors names, so that the Calibre {authors} "Arthur C. Clarke & Stephen Baxter" appears as "Arthur C. Clarke and Stephen Baxter" on the device. This is important because the Kobo firmware sorts the name incorrectly if this is not done (it sorts the book under Baxter instead of Clarke).

However I have just noticed that the metadata plugboard is not being applied when I update metadata in the device library with the current plugin. It seems to be just sending the original untransformed {authors} string. I don't know which was the last working version, but I could test them if that would help.

I am using Calibre 0.9.41 with Kobo Utilities plugin 1.2.2.

(Edit: It appears to be the plugin rather than a problem with Calibre or the Kobo driver itself, as books sent using "send to device" have the metadata plugboard applied correctly.)
