Hi
Auf der Seite zu den TV-Episoden fand ich leider nichts, zum durch nummerieren^^
Also episodeNumber sieht eigentlich wie dafür geschaffen aus um Episoden durchzunummerieren.
Wie auch in den Beispielen (Microdata) ersichtlich:
<div itemscope itemtype="http://schema.org/TVSeries">
<span itemprop="name">Greys Anatomy</span> is a medical drama television series created by
<div itemprop="author" itemscope itemtype="http://schema.org/Person">
<span itemprop="name">Shonda Rimes</span>
</div>
Starring:
<div itemprop="actor" itemscope itemtype="http://schema.org/Person">
<span itemprop="name">Justin Chambers</span>
</div>
<div itemprop="actor" itemscope itemtype="http://schema.org/Person">
<span itemprop="name">Jessica Capshaw</span>
</div>
<div itemprop="season" itemscope itemtype="http://schema.org/TVSeason">
<span itemprop="name">Season 1</span> -
<meta itemprop="numberOfEpisodes" content="14"/>
<meta itemprop="datePublished" content="2005-05-22">May 22, 2005
</div>
<div itemprop="season" itemscope itemtype="http://schema.org/TVSeason">
<span itemprop="name">Season 2</span> -
<meta itemprop="numberOfEpisodes" content="27"/>
<meta itemprop="datePublished" content="2006-05-14">May 14, 2006
<div itemprop="episode" itemscope itemtype="http://schema.org/TVEpisode">
<span itemprop="name">Episode 1</span> -
<meta itemprop="episodeNumber" content="1"/>
</div>
</div>
</div>
Alternativ gibt es "position" innerhalb des itemscopes von "episode", wie man es im zweischen Beispiel (Microdata) sieht:
<div itemscope itemtype="http://schema.org/TVSeries">
<a itemprop="url" href="http://www.bbc.co.uk/programmes/b006q2x0">
<span itemprop="name">Doctor Who</span></a>,
<div itemprop="season" itemscope itemtype="http://schema.org/TVSeason">
<a itemprop="url" href="http://www.bbc.co.uk/programmes/b00rs69w">
<span itemprop="name">Series 5</span></a>,
<div itemprop="episode" itemscope itemtype="http://schema.org/TVEpisode">
<a itemprop="url" href="http://www.bbc.co.uk/programmes/b00sj9sq">
<span itemprop="name">The Hungry Earth</span></a>,
episode <span itemprop="position">8</span>, broadcast on
<div itemprop="publication" itemscope itemtype="http://schema.org/BroadcastEvent">
<div itemprop="publishedOn" itemscope itemtype="http://schema.org/BroadcastService">
<a itemprop="url" href="http://www.bbc.co.uk/bbcone"><span itemprop="name">BBC One</span></a>
</div> at
<span itemprop="startDate"
content="2010-05-22T18:15:00+01:00">18:15, 22nd of May 2010</span>
</div>,
available on
<div itemprop="video" itemscope itemtype="http://schema.org/VideoObject">
<a itemprop="url" href="http://www.bbc.co.uk/iplayer/episode/b00sj9sq">BBC iPlayer</a>
</div> from
<div itemprop="publication" itemscope itemtype="http://schema.org/OnDemandEvent">
<span itemprop="startDate"
content="2012-06-02T19:45:00+01:00">19:45 on the 2nd of June</span> until the
<span itemprop="endDate" content="2012-06-09T19:44:00+01:00">9th</span>.
