Following up from the discussion at w3c/epub-specs#326, the EPUB Package Metadata Guide should include a complete example of series metadata. For instance, this seems to me the correct way to indicate that the book Princess in Training is #6 in the Princess Diaries series:
<meta property="schema:isPartOf">Princess Diaries</meta>
<meta property="schema:position">4</meta>
or (following Calibre’s convention) that the book The Princess Present is between Books 6 & 7 in that series:
<meta property="schema:isPartOf">Princess Diaries</meta>
<meta property="schema:position">6.5</meta>
… but of course the actual provided example should be checked for correctness by people more familiar with the arcana of schema.org records than myself.
