First of all, I am new to the forum. Big thanks to the development of Calibre. I have been an active user and really love it. It's an excellent tool, which I use for tagging.

My ebooks (largely epub, some pdf) are all tagged using Calibre. I use the goodreads plugin and my metadata is complete.

I only use Calibre for metadata scraping, but a different tool to serve the ebooks via opdf to my IOS devices. That's my preferred workflow.

I have a few questions:

1) Is it possible to embed the metadata within the epub file rather than in a separate opf file (or both)? I did quite some googling and it seems that the "Polish books" plugin is supposed to do so? I installed this, but doesn't seem to work (getting an error message that epub not supported). Any thoughts how I can embed the metadata within an epub file?

2) It seems that Calibre uses a a custom tag for series (<meta content="xxx" name="calibre:series"/>). This does not seem to be the official tag per epub specification (should be "belongs-to-collection"). Is there a way to add the epub tag "belongs-to-collection". This will be better supported as it is in line with official specification.

3) I'd like to change the "title" tag to combine "calibre:series" and "calibre:series_index" (i.e., Title tag reads "series name [series number]". Is there a way for me to create / override this tag and embed it in the epub file?
