I use a template when creating new ePubs - all the standard Cover/Title/CSS/OPF files already in a "default.epub" file which then gets Saved-As the new title. Everything has been going great until I realized that I've been forgetting to change the UUID in the OPF!
Code:
<dc:identifier id="BookId" opf:scheme="UUID">
urn:uuid:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx</dc:identifier>
Is there some magic formula or scheme that should be followed when creating a new UUID?
And, more importantly, does Sigil have a function for doing that? If not, can it be added??
