Wes Williams - Ramblings on software development
I was blown away a couple of months ago by Facebook's announcements at F8 . Timeline got a lot of attention, but I thought the addition of actions to the open graph protocol was equally interesting.
Last updated March 25, 2011. RDF/RDFa is major new functionality in Drupal 7 which describes Drupal entities (nodes, user, comments, terms) and their relationship in a format machines can understand. Mappings are defined between local Drupal entities and widely used vocabularies like Dublin Core, FOAF, SIOC, SKOS, etc.

For client using this stylesheet internally there is a "url" parameter you can set in your XSLT transformer to pass the URL of the XHTML document being transformed to the extractor. e.g. in Java: transformer.setParameter("url", "http://example.org/mydoc");

I initially associated RDF to data within XML documents that referenced data within other XML documents. Similar to how a XML document has associated XSD(s) that can reference other XSD(s). The difference is that RDF is interested in the meaning and relationships of the data instead of the data's structure.

RDF is a directed, labeled graph data format for representing information in the Web. This specification defines the syntax and semantics of the SPARQL query language for RDF. SPARQL can be used to express queries across diverse data sources, whether the data is stored natively as RDF or viewed as RDF via middleware.
