RDF, RDFa and the Semantic Web
The Semantic Web seems elusive both as a reality, and even as a concept. But at webBackplane we see it as central to the next generation of web applications. We understand RDF in a way that very few companies do, to the extent that it was our Managing Director Mark Birbeck, who devised and proposed RDFa as part of his work at the W3C. He has remained central to the initiative ever since, being the lead author of the RDFa in XHTML: Syntax and Processing document, and joint author of the RDFa Primer (with Ben Adida from Creative Commons).
At webBackplane we're also familiar with various open source tools that are part of the semantic web family, such as Jena and Sesame, and we've also created some of our own software, such as a JavaScript RDFa parser.
