Apps for Democracy: District CTO Vivek Kundra “While the immediate goal of the Applications for Democracy contest is to develop innovative software to present District data, its long-term goals are broader,” said District CTO Vivek Kundra. “By making government data easy for everyone to access and use, the District hopes to foster citizen participation in government, drive private-sector technology innovation and growth, and build a new model for government-private sector collaboration that can help all governments address the technology challenges of today and tomorrow.” Saturday, March 7, 2009

“Just” Open Have to download / import data Pure robot food - still needs programmers to make it play nice with humans Saturday, March 7, 2009

Amazon gives away free TB Amazon is storing public datasets - over 1 TB of data It actually saves them money, but it also makes their customers’ applications faster (processing next to data) Trevor O: if other hosting companies did this, then if even 2 people used it, they would save money - moving data across the LAN is cheaper than across the WAN Saturday, March 7, 2009

Read Write Web on Amazon Public Data Sets You've read, or can imagine, the impact that the ﬁrst Public Libraries had on human culture. Now imagine the opening up of not just this, but other libraries of data, so huge that economies of scale blast the project off beyond any analogy that could be drawn with our everyday experience or historical memories. It won't just be Amazon that offers up this kind of data - it will be relatively commonplace soon, we imagine. It will be like a network of libraries - for robots. Robots that go to the library frequently, read very fast and make serious use of what they've learned. Saturday, March 7, 2009

Where does Drupal come in? Saturday, March 7, 2009

Drupal is getting semantic Looks to be the ﬁrst general purpose CMS that has signiﬁcant semantic data out of the box If we ship Drupal 7 with semantic data turned on out of the box (i.e. content you create is automatically marked up), will probably be the most widely deployed semantic platform 200K downloads / month plus lots of people creating content = lots of semantic data from the bottom up Saturday, March 7, 2009

Linking Open Data …the data sets consist of over two billion RDF triples, which are interlinked by around 3 million RDF links (Oct. 2007) Saturday, March 7, 2009

Why should you care? Saturday, March 7, 2009

Views across the Web Remember the ﬁrst time you had your mind blown when building views? What if you could operate on any data, anywhere on the web, with a similar interface? That’s why you should care about the Semantic Web - it enables this This is where I mention SPARQL Saturday, March 7, 2009
