Simple but cumbersome and exposed to errors. A program like calibre should serve precisely to avoid and automate these procedures
Obviously your opinion on this topic is conclusive, but I would like to know the opinion on this enhancement of someone who works in a publishing house. |
Why do you have library management metadata in the EPUB, it didn't get there unless you put it there wittingly - perhaps with the Polish Tool, or you didn't prevent the editor putting it there. But the tool to remove it is the Modify ePub plugin - I have used it to remove non Dublin Core metadata elements on hundreds of thousands of ePubs.
Why are you so fixated on doing it within calibre, or by unpacking ePub and using a primitive editor and then repacking the ePub. Use the Sigil metadata edit tool, you can see it in the second screen shot in post #5. Select an element, press Ctrl+Del or click the Remove button, Save the ePub
If you want opinion on this issue from people who make ebooks for a living the best place to ask at MR is in the ePub or Workshop forum. Refer them to this thread.
