Update on the progress of two Linked Data projects, including one from US EPA and another from a Virginia based regional healthcare company using anonymized EMR and Linked Data for personalized healthcare.
UPDATE ON US GOVERNMENT LINKED DATA PROJECTS IN THE WILD Bernadette Hyland co-chair, W3C Gov Linked Data WG & CEO, 3 Round Stones, Inc. 28-April 2012 Alexandria VASaturday, April 28, 12This talk focuses on the impact of a government agency publishing data in a way that can beeasily exported and re-used by others.The EPA began the process of learning about and publishing data as Linked Data about a yearago ... A few pioneers in the Agency started looking at a Linked Data approach starting in2008.
THE PROMISE ... The Web is the natural place to publish information for public dissemination Transforming how we organize ourselves & how we’ll address the world’s most pressing problems in the 21st CenturySaturday, April 28, 12The Web is owned by no one and yet open to vendors, governments and private citizens.People in this eGov focused form would agree that Open Government Data initiatives and partnerships have thepotential to transform how we organize ourselves and how we address some of the world’s most pressingproblems in the 21st Century.These are worthy goals include better communication with citizens, eliciting input to better formulatepositions and policies.We have already seen improved response to natural disasters, human rights abuses, environmental andhealth issues to name but a few.

The good news is that we are living in a golden age. The bad news is that many or even most are having a difﬁcult timekeeping up.The Web is owned by no one and yet open to vendors, governments and private citizens.People in this eGov focused form would agree that Open Government Data initiatives and partnerships have the potential totransform how we organize ourselves and how we address some of the world’s most pressing problems in the 21st Century.These are worthy goals and include better communication with citizens, elicit input to better formulate positions and policies.
• Linked Data is about publishing and consuming data using international data standards • Based on 20 year old idea • A system of linked information systemsSaturday, April 28, 12I’m here in my role as the co-chair of W3C GLD WG as well as an entrepreneur who has successfullycompeted on the basis of both producing Open Source software & commercially supporting it.I’m a serial entrepreneur in this space & founded 3 different companies that led to several of the mostwidely used Open Source projects for Linked Data, including Mulgara, OpenRDF/Sesame, the PURLs2.0 and Callimachus.I’ve authored chapters in two of these peer-reviewed books which are available in hardcopy or for free,via the Web.
Saturday, April 28, 12With my W3C hat on this morning, I’m be talking about 4 and 5 star linked data.This means -- use URIs to identify things so that people can point at your stuff and link your data toother data to provide context.Publishing data on the Web using W3C standards is closely tied to realizing the beneﬁts associated withOpen Government -- to transform how governments serve citizens in the 21st Century.
Saturday, April 28, 12There is a revolution in data sharing underway. It is taking place inside the enterprise, behind thefirewall. It is taking place in software product development.It is taking place on the Web.
WE’VE SEEN THIS BEFORESaturday, April 28, 12Like HTML and RDF, credit cards have a human-readable side and a machine-readable side.
A BETTER APPROACH ... No one vendor owns it It scales to Web-scale Doesn’t require a super model Based on International Data Exchange Standards (RDF, SPARQL)Saturday, April 28, 12Scope: Bigger than any other deployed systemInﬁnitely adaptable: Changes piecemeal and allows for ad hoc additions & changes.Ownership: Nobody owns it
Saturday, April 28, 12Who is sharing their data as Linked Data? Small and large commercial and governmentorganizations, NGOs, Non-proﬁts ... plus many universities.Governments in the last few years have been responding to Open Government initiatives that mandatepublishing open government data.Some are careful, slow-moving entities who simply needed to ﬁnd real solutions to real problems.

FUTURE TRENDS? What is next for Open Gov Data on the Web We’re already seeing signs of things to come. Structured data on the Web is quickly becoming mainstream Authorities starting to appreciate a new way to publish and consume contentSaturday, April 28, 12What’s next? We are already seeing signs of the things to come.Structured data on the Web is quickly becoming mainstream.There have been many well-publicized triple challenges, hack-a-thons, apps challenges -- they are popping up everywhere.Organizations with mission critical applications based on relational technologies are creating a layer above their traditionalarchitectures and building Linked Data-driven Web apps.Web apps based on LD are beginning to replace traditional data warehouses.
