my main question is here in calibre forum:
https://www.mobileread.com/forums/sho...91#post2957091
this is a supplementary.
when I download a book, CC shows me what tags it found in calibre metadata.
it does not tell me about tags lurking within <dc:subject elements of opf, which also appear as tags when I import the book to mantano
mantano treats entries like these as tags:
<dc:subject>Science Fiction</dc:subject>
<dc:subject>Short Fiction</dc:subject>
<dc:subject>Fantasy</dc:subject>
<dc:subject>Suspense</dc:subject>
<dc:subject>Thriller</dc:subject>
<dc:subject>Mystery</dc:subject>
<dc:subject>Adventure</dc:subject>
but I've not tested other reader apps. is it wrong for Mantano to show these as tags, & if the answer to that is NO then is is right for CC to NOT show them as tags.
what mantano is doing may actually be more complex.. When a book has tags within calibre/ within CC , they seem to appear correctly in mantano, without having been written into the epub opf, The books that go "wrong", in my limited testing, are books with no tags in calibre / CC - mantano seems to then use the dc subject data, rather than show "no tags". I have not yet seen a combination of the calibre tags AND the dc subject tags show up in mantano bookshelves
I am a tad confused, as to what is supposed to be best practice here , but I suspect that other folks understand this well & there's no need for me to be testing all sorts of download routes/apps combos ?
i did test & observe that if I use
save to disc then calibre updates the tags in those dc fields with it's own data. I guess ideally it would be good if that also happened when CC downloaded a book from the content server?
I have not checked what CC does with tags when book is moved via the wireless device route.
