We hear a lot about how "semantic web" is "Web 3.0". We're using Semantic MediaWiki over at Centiare.com
. Anyone else familiar with this extension? We love it because it allows for multi-layered ASK queries (e.g., find me a home heating oil company, in business for 50 years or more, in New Jersey), and it automatically produces these RDF fields within articles that (we surmise) are making Google go ga-ga for our articles in search results.
Anyway, I'd be curious to know if anyone else is deploying this extension?
