It involves sideloaded books and calibre is involved.
An example is a series in which father & son both have written (stand alone) books. So it is per book registered in their respective OPF as:
Code:
Father book 1
<dc:creator opf:role="aut" opf:file-as="Lastname, J">J Lastname</dc:creator>
<meta content="HOT Serie" name="calibre:series"/>
<meta name="calibre:series_index" content="1.0"/>
Son book 2
<dc:creator opf:role="aut" opf:file-as="Lastname, K">K Lastname</dc:creator>
<meta content="HOT Serie" name="calibre:series"/>
<meta name="calibre:series_index" content="2.0"/>
To get rid off possible additional metadata author entries (like J Lastname & F Othername & P Yetanother), I'm using the metadata plugboard per default like:
Code:
any format:KOBOTOUCH {authors:list_item(0,&)}
That gets me always the first registered author per book. In my library system first entry is always the REAL author name: the others can be aliases or supporting authors.
After sending to KOBO ereader, I expect to see on series something like:
Code:
HOT Serie
J Lastname, K Lastname
Some times it does, but sometimes all I get is:
Code:
HOT Serie
J Lastname
When I reboot the KOBO, in 1 out of 3 reboots I'm indeed able so see again:
Code:
HOT Serie
J Lastname, K Lastname
No idea why, hence my question.
I figured that KOBO creates the Series info on-the-fly as it is not present in the DB, and it seems to do that after disconnection (from calibre) and after a reboot. Only the latter is more thorough (I assume) and succeeds more often.
BTW: I'm using the latest FW 4.20.14622 and have seen the same issue on a KA2 with the same FW, so it is not device dependend.
