I have my ebooks (EPUB3) with the following predefined metadata in it:
Code:
<metadata xmlns:dc="http://purl.org/dc/elements/1.1/">
...
<meta property="schema:wordCount">2123</meta>
<meta property="schema:numberOfPages">10</meta>
...
</metadata>
Would it be possible to import this into Calibre's custom columns, preferably with the same names? Or maybe there is some plugin that does it already?
