I just looked through a few of my purchased books.
I recently purchased
Wheel of Time Books #1-#6. #1 had an ISBN as the ID. The others used UUIDs.
And
The Expanse Book #5 had mismatching:
content.opf:
Quote:
<package version="3.0" unique-identifier="pub-id" xml:lang="en" xmlns="http://www.idpf.org/2007/opf">
[...]
<dc:identifier id="pub-id">urn:uuid:0b1a10e6-1feb-4d17-8695-8bbe5c18dacf</dc:identifier>
|
toc.ncx:
Quote:
|
<meta content="9780316217590" name="dtb:uid"/>
|
... tisk tisk!
And another Tor book had:
content.opf:
Quote:
<package version="3.0" unique-identifier="pub-identifier" xmlns="http://www.idpf.org/2007/opf" xmlns:dc="http://purl.org/dc/elements/1.1/" prefix="ibooks: http://vocabulary.itunes.apple.com/rdf/ibooks/vocabulary-extensions-1.0/" xml:lang="en" xmlns:dcterms="http://purl.org/dc/terms/">
<metadata>
<dc:identifier id="pub-identifier">randomid-d13</dc:identifier>
|
lol. Good ID, good ID.

I
think it may be used by some reading systems for highlights.
(Because I've had books where I've cleaned up/converted, forgot to change UUID, and the highlights carry over in all the wrong locations. After copying/pasting in new info, the old highlights disappeared.)

Where did you read this?
I just insert it exactly as it looks as ISBN-10 or ISBN-13.
