@davidfor or jgoguen

Did anyone of you tried using Epub3 serie information to auto update Kobo's database ?

I tried it without any luck so far. I also tried with latest beta firmware but again it was not working.

davidfor suggested that I try it in my plugin, but I haven't gotten to it yet. Could you post here (inside a code block) the metadata section of your packaging file (it has a .opf extension, frequently named "content.opf" from what I've seen) so I can see if it matches what I had in mind to test?

I copy pasted the example (lord of the ring) here : http://idpf.org/epub/30/spec/epub30-...itles-examples

I tried it with a real EPUB3 file.

That's unfortunate, that's the same example I was going to base my attempt on.

If you want to post the entire metadata section of your packaging file I can at least tell you if it looks like what I'm expecting based on my reading of the specification.

For those who are missing the covers when the use ".kepub.epub" books, there is a "simple" fix. For a couple of reason, today I loaded some ePub3 books. These had to be .kepub.epub to use the kepub reader. I was surprised when the books turned up in the library with a cover. I opened up the files to see how the cover was specified. The OPF file, in the <manifest> section, had the following line:

Code:
<item media-type="image/jpeg" id="cover" href="cover.jpg" properties="cover-image"></item>
When I looked at an ePub2, the equivalent line didn't have the "properties". I added this to the epub, copied it to the device, changed the extension and disconnected. The cover image was extracted and displayed correctly.

An interesting thing is that the cover image is used directly. For epubs, the device generates the first page of the book and uses that as the cover image. With the above, the it seems the image is extracted from the file and used.

With the usual "don't try this at home", "make sure you know what you are doing", "it's not my fault if you mess it up", to add this in calibre:

- Select the book
- Right click on it and select "Tweak Book"
- On the dialog that opens, press "Explode book". A window will open with the contents of the book.
- Find the OPF file. It is usually called "package.opf" or "content.opf". This file contains XML.
- Edit the OPF file. In Windows I use Notepad++ but Notepad should be OK.
- Find the "<manifest>" section.
- Somewhere before the "<manifest>" line, should be a line similar to above or the following.
Code:
<item href="Images/cover.jpg" id="cover.jpg" media-type="image/jpeg" />
- Add properties="cover-image" within the tag. THe above would then look like:

Code:
<item href="Images/cover.jpg" id="cover.jpg" media-type="image/jpeg" properties="cover-image" />
- Save the changes and close the window with the files in it.
- On the calibre window, press the "Rebuild Book" button.

The epub is now ready to be put on your Kobo device with the appropriate extension.
I have tried very hard, but I am afraid this does not work for me - I've even tried to rename the image file to "cover" just in case it made any difference, but I am afraid it does not. Frustratingly, the correct cover image is there as the first page of the book when I open it, but it does not show anywhere else: not when shutting off the device, nor in the home screen, nor in the shelves. Any ideas? I am attaching the specific book as it is in the public domain, but I cannot make this work with other epub files, either.

When I used Sigil to open the book you posted I found the following line in the content.opf file:

<item content="cover-image" href="Images/cover.jpg" id="cover.jpg" media-type="image/jpeg"/>

What I did not see was a line with the properties="cover-image" item as in the example below:

<item href="Images/cover.jpg" id="cover.jpg" media-type="image/jpeg" properties="cover-image" />

I would suspect that changing the content= to properties= in the line quoted might allow the cover to work. OTOH, Sigil was unhappy with either content or properties in that line which is more or less to be expected.

Regards,
David

mmh - actually the line
Quote:
<item href="Images/cover.jpg" id="cover.jpg" media-type="image/jpeg" content="cover-image"/>
is the last one before the </manifest> tag, while I cannot find the one you quote: could it be because I did not edit with Sigil? this is really bizarre!

After changing content= to properties= and the file type to .kepub.epub, the cover does display on my Glo either in sleep mode or power off mode.

David, this is so weird: if I open the opf with Sigil I see what you see, while with Wordpad I don't! Anyhow, I edited with Sigil, and now it works - so thanks a lot (though I cannot understand while with the Calibre tweaking I see something else!!!) Grateful for your help!
