Does Google's 'Define:' Use Schema.org Markup?

[triggerfinger]

Hi All,

I remember sometime last year I read about a way to markup definitions on your website so that Google would use it in its Define: function.

I believe this took the form of Schema.org markup, but I could be wrong.

I've been trying to track it down, but terms like "schema.org definition markup" just lead to definitions of markup and schema, not useful information.

Anybody have any idea where I could find the specs for this markup?

Thanks,

I would be surprised if it exists: you should not need extra markup for something that exists in HTML: the definition list.

There is a list of all schemas on schema.org, ad there does not seem to be anything there.

It surely at least existed, but I'm not sure if its supported anymore.

It has been changed in HTML5:

[w3.org ]

but it still looks like the official way to mark up definitions.

The issue that bothers me is whether search engines still recognise it due to wide abuse - a lot of designers treat it as a "spare" tag. I notice that some terms on a DL on my site do not appear in a Google definition search, even though they rank well for the same term for an ordinary search.
