[Pocketbook][epub2][Metadata] Attributes order

[sirtao]

Hello! I haven't find anything searching, so I'm writing this post.

In short: sometimes Calibre adds the Series metadata to ePub2 files as

  <meta content="Series Title" name="calibre:series"/>
  <meta content="1.0" name="calibre:series_index"/>

instead of

  <meta name="calibre:series" content="Series Title"/>
  <meta name="calibre:series_index" content="1.0"/>

This makes the Series metadata of the affected books be unable to be read by Pocketbook devices.

As I haven't yet managed to find the trigger, and since apparently this is a very old issue Pocketbook never bothered to deal with, there is a way to force Calibre to write the Nema attribute first and the Content attribute next?

Thanks you for the attention.

Not really attribute order in XML is arbitrary. You could add some code to calibre to force it, similar to what is done with <meta name="cover" content="xxx">

calibre uses lxml and that de-facto preserver attribute order. so you first delete the existing attributes and then reset them in the proper order.

Modifying the source code you mean?

or there is some configuration file I can edit?

source code.

I'll have to study the code, find where is the cover code and develop a way to replicate it for the series metadata, then.

Wish I was still in quarantine lol

Thanks

Admittedly I'm not using the latest version of calibre, but by adding an empty epub book to a series produces such series metadata for me. No big deal.

Sorry if I'm dumb: Do you mean adding an empty book in a series automatically updates the metadata on the other books in the series changing the order of the attributes to "name" and then "content"?


That said, to be fair this is more a Pocketbook firmware issue than a Calibre one.
I should pester them


still thank you a lot

There are a fair number of places metadata is written to epubs, but assuming you are using the send to device button in calibre, you would probably only need to change it in opf2.py
