Schema.org “Consumer” Apps
Though Google, Bing, Yahoo and Yandex are quick to point out the search engine optimization benefits of SCHEMA.ORG markup, we have yet to see applications that consume Schema markup and use it in interesting and useful ways. One possible exception: a Custom Search Application provided by Google that enables a webmaster (such as Thematix) to provide an on-site search engine, constrained by Schema.org types.
In this case, we specified that the pages had to have “Event” related markup. Is this of any use to you in spotting events, by say, subject matter (“Autos” or “banking”) or location (“Pittsburgh” or “London”)? The search is of the whole web, but emphasizes those with markup.
Type in a term and hit “Search” — what turns up?
