Interesting blog post w/video on RDFa and Drupal by Drupal‘s project lead.

RDF Extracted Attributes from Styled Elements (RDF-EASE)
CSS is an external file that specifies how your document should look; RDF-EASE is an external file that specifies what your document means.
…
.vcard { -rdf-typeof: "foaf:Person"; } .vcard .fn { -rdf-property: "foaf:name"; -rdf-datatype: "xsd:string"; } .vcard .url { -rdf-rel: "foaf:page"; } /* This scopes everything within the hCard as applying to the * hCard as a whole. */ .vcard, .vcard * { -rdf-about: nearest-ancestor(".vcard"); } <div class="vcard"><a class="fn url" href="http://example.com">Joe Bloggs</a></div> <div class="vcard"><span class="fn"><a class="url" href="http://example.com">Joe Bloggs</a></span></div> <div class="vcard"><a class="url" href="http://example.com"><span class="fn">Joe Bloggs</span></a></div>
Now, that’s an intriguing idea — which could of course also be applied to Topic Maps.
The Semantic Web in Action?
This month’s Scientific American (Dec 2007, 297:6) features an 8 pages long article entitled The Semantic Web in Action by Feigenbaum, L. et.al.
The authors basically discuss the Semantic Web vision as laid out by Tim Berners-Lee, et.al. in the famous 2001 The Semantic Web article, and how some steps towards such a Semantic Web have been made.
In it, they define the semantic web as
A set of formats and languages that find and analyze data on the World Wide Web, allowing consumers and businesses to understand all kinds of useful online information.
A tad general perhaps, but anyways… On the technology front, RDF/OWL and some uses and applications of these technologies, like FAOF, is mentioned, while a few use cases are discussed.
Although the use cases are interesting, the authors fail to even mention Topic Maps as a semantic web technology, and limit the technological discussion to RDF/OWL alone, stating that “The data language, called Resource Description Language (RDF)…” (emphasis added). Read the full post »
