The Gov2.0 Summit in is on its second and last day in a warm and quite sunny Washington DC. Weather is not of great importance though since the Summit is being held three stories below ground level at the Grand Hyatt Hotel. The event is fully booked and filled with interesting presentations and panels. Expressions like “Government as a platform”, “the cloud”, “Open up the data archives” and Tim O’Reilly’s favorite “Do things that matters” are frequently used. US Government officials as well as entrepreneurs explains how they work with social media components, citizen participation and data visualization together with geodata to provide better service for the citizens as well as creating tools for internal use. The area of accessibility has however not really been touched upon as of yet. The rest of the day will be filled with talks about policies, security, transparency, healthcare and “.gov websites that work”. On thing that was brought up on a number of occasions yesterday was the “Apps for America 2: The challenge” managed by the Sunlight Foundation. A number of web applications were developed on top of the data from the website. The purpose of is to increase public access to high value, machine readable datasets generated by the Executive Branch of the Federal Government and the purpose of the challenge was to see what creative developers might come up with. The result was a very interesting and some very useful apps. Great work and great initiative! What also came out of this was that once again stress the importance for government websites to publish all information and data in machine readable formats (i.e. NOT PDF) to make data collection and mash-ups possible.
