Ivan Herman
just posted another nice example of practical RDFa usage in a blog post
titled:
Yet Another RDFa Proccessor. In his post, Ivan exposes a
URI
for his FOAF-in-RDFa
file.
Since I am
aggressively tracking RDFa developments, I decided to quickly
view
Ivan's FOAF-in-RDFa file via the OpenLink RDF Browser. The full
implications are best understood when you click on each of the
Browser's Tabs -- each providing a different perspective on this
interesting addition to the Semantic Data Web (note: the Fresnel Tab which
demonstrates declarative UI templating using N3).
What's Going on Here?
The OpenLink
RDF Browser is a Rich
Internet Application built using OAT (OpenLink Ajax Toolkit). In my case,
I am deploying the RDF Browser from a Virtuoso instance, which
implies that the Browser is able to use the Virtuoso
Sponger Middleware (exposed as a REST Service at the Virtuoso
instance endpoint: /proxy); which includes an RDFa Cartridge
comprised of a metadata extractor and an RDF Schema / OWL
Ontology mapper. That's it!
