what do you do with the .opf?
keep it or dump it?
EDIT: Also, is epubcheck included in caliber? or is it worth it for me to run it afterwards?
I'm getting a bunch of epub files that don't work.

Any idea why they can sometimes be fixed by converting epub->epub again?

Not quite sure what you mean... If you're producing EPUB output, the EPUB file will contain a copy of the source OPF.

Calibre does not include epubcheck, nor does it necessarily produce output which passes epubcheck. For example, epubcheck checks that the HTML content is fully valid XHTML, which calibre does not enforce. If you're producing your own markup, using epubcheck to find errors in your markup is probably a good idea.

Nope -- that really shouldn't happen. You should probably open a ticket about it on the Calibre trac, including an example which produces the bad EPUB.

Or you could pre-process your XHTML flows with Tidy before using Calibre...

sorry I thought the .opf maybe it is oeb. I mean the other file that caliber produces upon saving to a directory. I noticed an error fix in the latest version of caliber talking about the opf file so I assumed it was called an opf file.

what does the error fix do? Should I reconvert books to correct any errors?



I don't have XHTML files, I am usually converting pdf's or lit files depending on what the author offers for download.

Tidy will fix most of the problems with incorrect XHTML.
