For the past three years, through the Health Data Initiative, the Department of Health and Human Services (HHS) has focused on the liberation of health data.  This effort has focused on making data from HHS holdings more easily available without affecting privacy or confidentiality of individuals.  The intention is that entrepreneurs, developers, researchers and policy makers will take the newly liberated data and create web or mobile applications, products and services to help improve health for consumers, communities and service providers. Since 2010, over 300 data sets have been uploaded to and in addition to the many events and examples of health data being leveraged than ever before. Read more »

Earlier this summer, the U.S. Chief Information Officer, Steven VanRoekel released the federal government’s new digital strategy which aims to shift the way government information is accessed and consumed.  Instead of focusing on producing a final product, which has been common practice for years, the government will now be making content more accurate, available and secure.  One major tool in the information technology tool box being used to achieve this goal is the use of Application Programming Interfaces (APIs). 
An API is a set of tools for building software applications.  But more importantly, an API makes information more accessible.  This is important for two reasons.
First, the use of APIs make it easier to replicate government information across more places than ever before.  APIs enable automatic updates of information when content is syndicated on other websites, while reducing actual person hours currently spent manually updating content.  Read more »

The first of three rounds of’s developer challenges are currently open for submission! Health is hosting three rounds of challenges that focus on one of two areas, domain or platform. The first round features two challenges that are putting developers to the test; the first to focus on data integration and liquidity is the Metadata Domain Challenge
The Metadata Domain Challenge requests the application of existing voluntary consensus data standards for metadata common to all types of government data, and invites new designs for health domain specific metadata to classify datasets in our growing catalog, creating entities, attributes and relations that form the foundations for better discovery, integration and liquidity. Open to submission until October 2, 2012, the winner will demonstrate the application of voluntary consensus and de facto cross domain and domain specific standards to as many of the U.S. Department of Health and Human Services datasets available on  The two objectives are to: Read more »

This presentation is an overview of new features, upcoming capabilities and related developer challenges given at the 2012 HDI III Forum day 1 afternoon breakout session from 1-2:30pm on Tuesday, June 5 in room 103B. In it we describe how our platform architecture goals align with complementary IT trends like Linked Data and Big Data. The slides are often screenshots that link to what's depicted, so (after focusing your cursor in the iframe) you may want to use your arrow keys to step forward and backward, and only click the slides when you want to link through to and other sites being referenced. If you find the screenshots in the embedded widget on this page a bit blurry, you can download the high resolution presentation (~13M).  Read more »
