Is series information (name of series and number of this work in that series, at least) handled in some standard or consistent way in epub-land? That is, is there something I can put in the epub that many or most readers will recognize and use?

Calibre puts something like this in a "write to disk" epub:

<meta name="calibre:series" content="Bresden Files"/>
<meta name="calibre:series_index" content="14.0"/>

but that doesn't look like something most readers would recognize.
