HTML Browsers

• RDF can be serialized in RDFa• Have you heard of– Yahoo’s Search Monkey– Google Rich Snippets?

• They are consuming RDFa• But WHY?

Because there is life beyond ten blue links

Google and Yahoo are starting to crawl RDFa!

The Semantic Web is a reality!

The Reality

• Yahoo is crawling data that is in RDFa and Microformats under a specific vocabularies – FOAF– GoodRelations– …

• Google is crawling RDFa and Microformats that use the Google vocabulary

• How much of this is Linked Data– I don’t know

Linked Data Browsers

Linked Data Browsers

• Not actually separate browsers. Run inside of HTML browsers

• View the data that is returned after looking up a URI in tabular form

• (IMO) UI lacks usability
