The government needs to make sure that they post actual data in a portable format like XML. The EPA publishes emissions data http://camddataandmaps.epa.gov/gdm/ in portable XML formats for scientist and the public to use the data as they need. For example, http://www.govtrack.us/ uses publicly published data to deliver a complete service. Having the data available as a feed or a series of published data files instead of some static website enables everyone else to see the details and deliver meaningful content.

'cause I can.
