Merely importing a book into Calibre adds the metadata. As I understand it, that's a prerequisite to being able to use Calibre's TOC Editor on it...

EDIT: As for an example, I just added an EPUB into my Calibre library, did nothing to it, and used Save to Disk to make a copy. It made the following OPF changes that I consider "dirtying it up":
  • Removed the BOM from the file, making it an improper UTF-8 file.
  • Moved the title below the author, removing the indentation in the process.
  • Modified the date/time.
  • Removed the (empty) subject field.
  • Inserted Calibre-specific metadata: title_sort, user_categories, and author_link_map (also with botched indentation)
  • Inserted a contributor credit for itself.
  • Inserted a second, Calibre-specific, identifier field.
You may be fine with those changes. I am not.
