Like I said:

> There are dedicated consumers for some of these vocabularies -- in particular the schema.org and data-vocabulary.org vocabularies are used for rich snippets in search engines. But there are also generic consumers of the data which use the types to aid people's searches. For instance, Sindice [1] enables you to search for pages that contain information about things of particular types. For example, you can search for foaf:Documents on "HTML5":

>  http://sindice.com/search?q=HTML5&nq=&fq=class%3Ahttp%3A%2F%2Fschema.org%2FNewsArticle

I expect that the sites are aiming to support both the dedicated consumers that recognise a single vocabulary and the general-purpose consumers that support users' search across multiple unconstrained vocabularies.
