metadata & OPF files

u238110 · 11-19-2014, 11:12 AM

I created an epub by using a web page that someone had made out of the book, however when I went to create metadata for the book, it seems like it put it in an OPF file (book saved as EPUB plus an OPF). Isn't there a way to have metadata stored in just the EPUB?

Metadata.OPF file is the Calibre(DB record) backup

BTW new users (take the time to learn what can be done,very carefully) should really treat calibre folders as a Black Box. Making changes can damage your Library
Calibre GUI and Plugins do most everything a user could want (except refill your

)

Does that include not storing it in a DB (as in, metadata.db)?

Yes, of course. Don't import it into calibre.

calibre saves a backup of all metadata, in the metadata.opf -- which shouldn't bother you unless you are looking up calibre's skirt. It takes up hardly any room, and you will be exceedingly grateful it is there if you ever have to restore a corrupt database.

I am also confused about editing metadata.
It appears to me that the only way of really changing the stuff is to convert the book (again).

Or, um, doing anything with the book.

Send to device, Save to disk, Polish books, Embed Metadata...

There are 2 basic paths:

Path 1, the Library copies are unchanged, but the destination is made current: Send to (Device or Folder) or Save to disk <<< This is NOT the Library

Path 2, Refresh the Library contents (when the format supports):
Polish, Embed Metadata, Conversion (only the target format) Modify EPUB PI

Is there a way to edit/view metadata outside of Calibre?

mobi2mobi, Java Mobi Metadata Editor.

Neither can view and edit more than one book at a time, and you have to manually select the book's location...

The names suggest MOBI not EPUB.

Editing the exth fields in dual-MOBIs recently came up, and my mind was in a loop. I lost track of what this thread was about.
