16/07/2008: Extending hCard with RDFa
hCard is an HTML-based format for describing contacts (people, organisations, etc) on web pages. It allows you to mark up which elements represent their name, their address, their birthday and so forth.
While hCard offers many useful properties that can be used to describe contacts, some are considered beyond the scope of the hCard specification. This is where RDFa comes in…

09/03/2008: The Semantic Web
One of my current interests is the semantic web — that is, the push to move from publishing text on the Web to publishing structured data, which can actually be understood by computers (in so far as a computer can truly “understand” anything). By publishing information so that computers can understand it, you make the Web into a huge mine of interconnected data, free to be queried by everyone.
As an example of what I mean, searching for the keyword “train” on Google brings up results related to:
- trains, as a form of transport
- the band Train
- IT training courses
- toy trains
In the semantic web, the search engine and my computer would inherently understand the difference between these concepts, so if I wanted to know about the new Train album, I wouldn’t get any result related to locomotives!
What I’m particularly interested in is ways of embedding semantic data in ordinary web pages, so that we have a single web that can be…
