Embed series into books

Any idea what happens if you use the Polish function and then instead of using Calibre's send to device button you were to open the folder the book is in (in Calibre's library) and drag it onto the Kobo; does the Kobo pick up the series info, for epub2s since the series info inside the book is Calibre-specific.

The Kobo would not pick up the series info since while calibre's series info is as close to a standard as there is for epub2, it is not a standard nor is it Dublin Core metadata. By the way, when you send an ebook to a Kobo or do a save to disk, the metadata is embedded into the output file.

For comparison, the first spoiler is the content.opf from the ebook in calibre while the second is from the ebook as sent to a Kobo.

Just a FYI, NickelSeries for Kobo reads the series metadata when the device is unplugged, doesn't matter if it was sideloaded.

Ok, thanks. So my and the OP's wishing it was embedded in the book when it's in Calibre's library may make some logical sense but not practical sense.

I tend to treating the calibre library as a black box and I don't worry about what is inside there as long as what comes out meets my needs. I learned a lesson about a decade back about not mucking around with the calibre library.
