I'm not completely familiar with how KTE works internally, but do note that the subtitle must be embedded in the EPUB with EPUB3/calibre-style metadata for NickelSeries to see it. Open one of the EPUBs from the KOBOeReader drive as a zip file, and see if it's in the package document (usually a .opf
file) within.
From @jackiew1 on MR:
I don't use NickelSeries myself but I seem to remember, for Subtitle to be populated during the first USB connection, the subtitle text needs to exist in a calibre custom column with lookup name #subtitle. There was some discussion about it in the early parts of this thread.
Changed, and confirmed that still not works. But works after second
This info is embebed in the opf file
"#subtitle": { "#extra#": 2.0, "#value#": "Volume", "category_sort": "value", "colnum": 3, "column": "value", "datatype": "series", "display": { "description": "" }
It looks like calibre saves custom metadata for EPUB3 books in a different way compared to EPUB2, and the reading the code, it seems like that can only handle EPUB2 (or EPUB3 files with native subtitle metadata, which calibre can't write)
If I understand this code correctly, it's looking for a <meta name="calibre:user_metadata:#subtitle"/>
element, with content roughly like this: (ignoring the properties it doesn't read) {"#value#": "subtitle goes here"}
. Opening a random EPUB2 book I have, it matches that exactly, and NickelSeries properly imports the subtitle for this book
However, in an EPUB3 book, calibre saves custom columns like this:
<opf:meta property="calibre:user_metadata">{
"#subtitle": {
"#extra#": null,
"#value#": "subtitle goes here",
"category_sort": "value",
"colnum": 7,
"column": "value",
"datatype": "text",
"display": {
"description": "",
"use_decorations": false
},
"is_category": true,
"is_csp": false,
"is_custom": true,
"is_editable": true,
"is_multiple": null,
"is_multiple2": {},
"kind": "field",
"label": "subtitle",
"link_column": "value",
"name": "Subtitle",
"rec_index": 26,
"search_terms": [
"#subtitle"
],
"table": "custom_column_7"
}
}</opf:meta>
which is completely different from what the code expects, and thus it can't import the subtitle
I installed NickelSeries on a Libra 2 running firmware version 4.38.21908, but after testing, the subtitle isn't passing without connecting a second time to the PC.
Keep in mind that I'm using the template "{#subseries} {#subseries_index}" for the subtitle on KoboTouchExtended. It works if I connect the Kobo a second time.
KoboTouchExtended is set to "update metadata on device" and "sending books to devices" set to "Automatic management"
