Pocketbook 626: Metadata Info not correctly displayed

[KoopaOne]

Hi,

there is a know problem, that the Pocketbook Devices (at least the Lux2) doesn't correctly show the correct book info, if the metadata isn't organized in a special way. It seems, that the Pocketbooks stop to read data from the series_info onwards.

Metadata that works:

<dc:subject>Versuch</dc:subject>
    <dc:language>de</dc:language>
    <dc:identifier opf:scheme="calibre">0587642b-2b94-4384-a79a-49541fa8a24d</dc:identifier>
    <meta content="0.7.2" name="Sigil version"/>
    <meta content="Metadaten-Test" name="calibre:title_sort"/>
    <meta content="{&quot;Klecks&quot;: &quot;&quot;}" name="calibre:author_link_map"/>
    <meta content="2014-10-26T10:28:34.540000+00:00" name="calibre:timestamp"/>
    <meta name="calibre:series" content="eBook Testdateien"/>
    <meta name="calibre:series_index" content="1.0"/>
    <meta name="cover" content="cover"/>

Metadat that does't work:

<dc:subject>Versuch</dc:subject>
    <dc:language>de</dc:language>
    <dc:identifier opf:scheme="calibre">928e1c34-32f7-497d-9437-b91765614d10</dc:identifier>
    <meta content="0.7.2" name="Sigil version"/>
    <meta name="calibre:series" content="eBook Testdateien"/>
    <meta name="calibre:series_index" content="1.0"/>
    <meta content="Metadaten-Test" name="calibre:title_sort"/>
    <meta content="{&quot;Klecks&quot;: &quot;&quot;}" name="calibre:author_link_map"/>
    <meta content="2014-10-26T10:28:34.540000+00:00" name="calibre:timestamp"/>
    <meta name="cover" content="cover"/>

As you can see, the only difference is the position of the calibre:series related information.

I already tried to edit the file \calibre-master\src\calibre\ebooks\metadata\opf2.py, but my python and knowledge of the calibre source isn't good enough to recognize where i have to change the source to get calibre to write the medadata in a format the Lux2 can recognize.

I already tried to change the smart_update, but that didn't work ...

    def smart_update(self, mi, replace_metadata=False, apply_null=False):
        for attr in ('title', 'authors', 'author_sort', 'title_sort', 'publisher', 'rating', 'isbn', 'tags', 'category', 'comments', 'book_producer', 'pubdate', 'user_categories', 'author_link_map', 'series', 'series_index'):
            val = getattr(mi, attr, None)
            is_null = val is None or val in ((), [], (None, None), {})
            if is_null:
                if apply_null and attr in {'series', 'tags', 'isbn', 'comments', 'publisher'}:
                    setattr(self, attr, ([] if attr == 'tags' else None))
            else:
                setattr(self, attr, val)

Can someone help?

You want to modify the render() method. You'd have to re-arrange the child elements of the metadata element before rendering. Something like this:

for child in tuple(self.metadata):
if child is to be moved to end:
self.metadata.append(child)

Currently the method looks like this:

   def render(self, encoding='utf-8'):
        for meta in self.raster_cover_path(self.metadata):
            # Ensure that the name attribute occurs before the content
            # attribute. Needed for Nooks.
            a = meta.attrib
            c = a.get('content', None)
            if c is not None:
                del a['content']
                a['content'] = c

The above code switches just "name" and "content" within one metadata line, right? So how would i delete a metadata line and move it to the end?

I simply want these two lines to be at the end:

  <meta name="calibre:series" content="eBook Testdateien"/>
  <meta name="calibre:series_index" content="1.0"/>

how would that code look like? I tried this, but nothing happens ...

   def render(self, encoding='utf-8'):
        for meta in self.raster_cover_path(self.metadata):
            # Ensure that the name attribute occurs before the content
            # attribute. Needed for Nooks.
            a = meta.attrib
            c = a.get('content', None)
            if c is not None:
                del a['content']
                a['content'] = c
			#Ensure that the Series Stuff is at the end of the metadata
			# Needed for Pocketbooks
			d = a.get('name', None)
			if d == 'calibre:series' or d == 'calibre:series_index':
				self.metadata.append(meta)

for child in tuple(self.metadata):
  if 'calibre:' in child.get('name', ''):
     self.metadata.append(child)

Hi, I have the same problem with metadata for PB 626 TL3. For some books to me everything is displayed correctly, and for some it omits the series and serial number. Please instruction on where to find the file where you paste the above code. Thank you.

Are you using the latest version of calibre? There was a recent fix for this, I believe.
