I mentioned in an earlier blog that I would dig deeper into some of the Web 2:0 Architectural patterns. Well I came across a very good web site whichI think shows very simply a web 2:0 mashup.
They are essentially mashing together a database of information (prices of houses sold from the UK Land Registry) with a map, not hard really but very useful as it adds a new dimension to the understanding of the data by visualising it, and comparing it to places near by (something that is harder to do by looking at a list of addresses).
