[Mister L]

Hello, thanks for this plugin.

I am converting some epub2 files to epub3 and cleaning them up a bit.

The original epub2 files have a BookID in the form of a url. I want to replace them with a standard urn:uuid. This plugin seems like it could perfectly do that but when I tried it on a test file (open epub2 file, run plugin, no other actions), this problem is found and the log says it has been replaced, but in fact the uuid is not added to the opf and instead almost all the metadata has been removed.

Here is an example using a Project Gutenberg file.

IDErrorCheck Log:

Spoiler:

***** IDErrorCheck Log *****

toc.ncx(Book ID) ** line 6 **
Bad format: "http://www.gutenberg.org/19657"
Replaced with: "urn:uuid:4c6c0f8b-6fbe-4f91-97b9-3351409d4f5a

Original metadata in the opf:

Am I missing something? Is there different way I should do this?
