Linking superEvent property in Microdata with itemref

问题

I'm adding Microdata to a page and I'm trying to associate a list of events to a superEvent, but I don't manage to make it work when checking at: http://www.google.com/webmasters/tools/richsnippets?q=

Here the concept code:

<div id="main" itemscope="main" itemtype="http://schema.org/Event">
<span itemprop="name">Main
</div>
<div itemscope="event" itemtype="http://schema.org/Event">
<span itemprop="name">Event
<span itemprop="superEvent" itemref="main">
</div>

Any idea?

Problems with your Microdata:

itemscope is a boolean attribute, so you should not give it values like "main" or "event".
The itemref attribute can only be used on elements with itemscope, so you can’t use it like that.

To link events via the subEvent/superEvent properties, you could either use the itemref attribute or nest the items.

With itemref and superEvent, it could look like:

<div itemprop="superEvent" itemscope itemtype="http://schema.org/Event" id="main">
  <span itemprop="name">Main</span>
</div>

<div itemscope itemtype="http://schema.org/Event" itemref="main">
  <span itemprop="name">Event</span>
</div>

With itemref and subEvent, it could look like:

<div itemscope itemtype="http://schema.org/Event" itemref="secondary">
  <span itemprop="name">Main</span>
</div>

<div itemprop="subEvent" itemscope itemtype="http://schema.org/Event" id="secondary">
  <span itemprop="name">Event</span>
</div>

Nesting (without using itemref) could look like:

<div itemscope itemtype="http://schema.org/Event">
  <span itemprop="name">Main</span>

  <div itemprop="subEvent" itemscope itemtype="http://schema.org/Event">
    <span itemprop="name">Event</span>
  </div>

</div>

I managed to do this in the end:

<div id="main" itemprop="superEvent" itemscope="main" itemtype="http://schema.org/Event">
<span itemprop="name">Main
</div>
<div itemscope="event" itemtype="http://schema.org/Event" itemref="main">
<span itemprop="name">Event
</div>
