ePub version in template function?
Is there any way to identify the ePub version using template programming language (or a plugin) for use in a column?

The answer depends on what you are want to accomplish. What are you trying to do?

To be able to see what version epub it is without opening it and to use that info to decide what other steps I take with the book.

Ahh, sorry I missed the word "version". There is nothing in the template language that can do that. A plugin could open the book's OPF and check, but I don't know any plugin that does that.

This is a manual process that will identify and select epub3 books. You then must use the list to set a column, probably Yes/No.

The steps:
  1. One time: create a column to store the results. I assume it will be a Yes/No column named Is Epub3 (#isepub3)
  2. Use Bulk Metadata Edit to set #isepub3 to false (or empty) for all books
  3. Use Quality Check to search the OPF for
  4. Code:
    xmlns="http://www.idpf.org/2007/opf" version="3.0"
    That is probably safe and won't find any non-epub3 books.
  5. Calibre will show all books that matched. Select them.
  6. Use Bulk Metadata to set #isepub3 to true.
  7. Use #ispub3 in your templates.
You must repeat the above process anytime a book is added or might change from 2 to 3 or vice versa.

Thanks for this recipe.

However, since most of my books are only in an Amazon format or PDF at this point, I created a Text column with 3 values: Yes,No,"" and set default to "".

Then selected all ePub and bulk updated that list to 'No'.

Finally ran the OPF search and set those to 'Yes'.

You could have done this with a yes/no column unless you have changed them from tristate (yes, no, empty) to bistate (yes, no).

Your solution does permit adding more options, as would using a "Text, but with a fixed set of permitted values" column.
