At WPC 2010, Microsoft said that “”Dallas” Information arketplace, which provides developers and other information workers the ability to find, purchase and manage datasets from one online resource, powered by Windows Azure platform, will go live in the fourth quarter of this year.”Some datasets on the service are “premium,” meaning available for a fee, but many are free of charge and will continue to be free, even after launch. It’s up to the dataset providers whether or not to charge. Currently, in its pre-launch state, Dallas offers datasets from AP, InfoUSA, the FDA, NASA, WHO and others.
Already, over 3000 developers have set up accounts on Dallas and are using the datasets to run app that can run on Silverlight on web as well as on mobile devices like iPhone. For e.g., one of the companies using Dallas is Tableau, which was featured during a keynote at WPC this week where their visualization of UNESCO data (a heatmap) was showcased.
