Let me piggyback on this. In Calibre, I made multiple copies of a compendium:
https://www.mobileread.com/forums/sh...d.php?t=364235
and deleted the files I didn't want in each one to split them. I made no changes to Unique Identifiers. But, I get no errors when I check and all seems good to me. Could you be more specific about that Unique Identifier?
In the .opf, the top line includes:
unique-identifier="uuid_id"
a few lines below that, there are various identifiers For instance:
Code:
<dc:identifier>amazon:0765320665</dc:identifier>
<dc:identifier>isbn:9781466831032</dc:identifier>
<dc:identifier>mobi-asin:B009WUGASU</dc:identifier>
<dc:identifier>calibre:2164</dc:identifier>
<dc:identifier>uuid:bf2d8a56-b379-4614-a9ac-59396cff3480</dc:identifier>
<dc:identifier id="uuid_id">uuid:fb7d84d9-5199-40b2-bf69-c36722777f61</dc:identifier>
I did change the isbn id in each book, so those are unique across the split books (though the amazon and mobi-asin identifiers are not unique (the calibre identifier is unique, though)). And, the uuid identifier (5th line of the above) seems to have been generated on its own, so it looks unique. But the id="uuid_id" identifier (last line, just below the before-mentioned uuid identifier) that looks to be what the top line references is non-unique. Ditto for the <meta name="dtb:uid" content=... line in the .ncx (which is the non-actually-unique uuid_id).
Is that bad? Should I replace the uuid_id with what's in the uuid line just above it and then delete that uuid line (and copy the string to the .ncx)?
