Developer Hub, Software Challenges, the Developer Apps Showcase, and the Developers forums are just four of the sections that are worthy of your attention on Data.gov.
My inner geek find the large quantity and type of data available on Data.gov fascinating. The site’s expanded offerings were announced on the one year anniversary of the U.S. government’s digital strategy directive, which has a big focus on mobility.
The variety of data on Data.gov is overwhelming, so it helps to have an idea of what you want or need before you start perusing the site. I wasted a lot of time trolling Data.gov and finding so much that was interesting but had no real application for my development work (the White House visitor records is a great example). Data.gov includes everything a developer needs to utilize its massive amount of data.
