This talk focuses on the impact of a government agency publishing data in a way that can be easily exported and re-used by others.The EPA began the process of learning about and publishing data as Linked Data about a year ago ... A few pioneers in the Agency started looking at a Linked Data approach starting in 2008.
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 Century
Saturday, April 28, 12
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 to transform how we organize ourselves and how we address some of the world’s most pressing problems in the 21st Century.
These are worthy goals include better communication with citizens, eliciting input to better formulate positions and policies. We have already seen improved response to natural disasters, human rights abuses, environmental and health issues to name but a few.

Semantic technologies, and specifically a Linked Data approach, provide greater computing context. 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 time keeping 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 to transform 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 systems

I’m here in my role as the co-chair of W3C GLD WG as well as an entrepreneur who has successfully competed 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 most widely used Open Source projects for Linked Data, including Mulgara, OpenRDF/Sesame, the PURLs 2.0 and Callimachus. I’ve authored chapters in two of these peer-reviewed books which are available in hardcopy or for free, via the Web.

With 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 to other data to provide context. Publishing data on the Web using W3C standards is closely tied to realizing the benefits associated with Open Government -- to transform how governments serve citizens in the 21st Century.

There is a revolution in data sharing underway. It is taking place inside the enterprise, behind the firewall. It is taking place in software product development. It is taking place on the Web.
WE’VE SEEN THIS BEFORE

Like HTML and RDF, credit cards have a human-readable side and a machine-readable side.
No one vendor owns itIt scales to Web-scaleDoesn’t require a super modelBased on International Data Exchange Standards (RDF, SPARQL)
A BETTER APPROACH ...
Saturday, April 28, 12
Scope: Bigger than any other deployed systemInfinitely adaptable: Changes piecemeal and allows for ad hoc additions & changes.Ownership: Nobody owns it
Saturday, April 28, 12
Who is sharing their data as Linked Data? Small and large commercial and government organizations, NGOs, Non-profits ... plus many universities. Governments in the last few years have been responding to Open Government initiatives that mandate publishing open government data. Some are careful, slow-moving entities who simply needed to find real solutions to real problems.

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 content
FUTURE TRENDS?
Saturday, April 28, 12
What’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 traditional architectures and building Linked Data-driven Web apps. Web apps based on LD are beginning to replace traditional data warehouses.
