A huge milestone was reached yesterday with the relaunch of the U.S. government data portal on a single, open source platform. A joint collaboration between a small UK team at the Open Knowledge Foundation and data.gov, this was an ambitious project to reduce the numerous previous catalogs and repositories into one central portal for serious re-use of government open data.

Catalog.data.gov brings together both geospatial as well as “raw” (tabular or text) data under a single roof in a consistent standardised beautiful interface that can be searched, faceted by fomat, publisher, community or keyword as well as filtered by location.

Users can quickly and easily find relevant or related data (no longer a metadata XML file!), download it directly from the search results page or preview spatial map layers or CSV files in the browser.

Of course, there is still work to do, especially about improving the data quality, but nonetheless a vast amount of effort went into metadata cleanup, hiding records with no working links and adding a flexible distributed approval workflow to allow review of harvested datasets pre-publication.

Szelena Gray is the Executive Director of Rootstrikers, a new generation of activists founded by Lawrence Lessig to take a stand against the corrupting influence of money in politics. Found a good story about corruption? Use #Rootstrikers.

There are many ways to define smart consumerism — including being budget, GMO, organic, or fairtrade conscious. Why not add corruption to the list?

For companies whose products we buy every day, it's business as usual to spend millions of dollars to influence public elections. Yet most Americans don’t shop according to their views on money in politics, and if they would, might not know where to begin. On May 19th, Rootstrikers in fourteen cities across the country will aim to change that with a public education campaign about the money that flows into politics from some of our favorite brands.

Here's the plan: Rootstrikers will head to local consumer haunts and, with the help of a radical new app called BizVizz -- an iPhone app that provides people with data on corporate accountability including taxes, government subsidies and federal campaign contributions -- will shine a light on the connection between our shopping carts and congressional coffers.

BizVizz is powered by Sunlight’s Influence Explorer API with public data from Federal Election Commission filings, IRS filings and other government records.

I've long been obsessed with maps. When I was a kid on road trips, I loved tracking our journey in the road atlas. When I lived in Brooklyn in the 90s, I covered my bedroom walls with AAA state maps with my then-recent three month cross country journey traced out on them. Maps always provided me with a way to locate myself in space and a way to understand my trajectory. In the last couple of years, I've started to see them differently. The maps I'm thinking about don't locate us or help us see a trajectory of growth or journey. They trap us. Specifically, they keep us attached to elected representatives that don't often have our best interests in mind.

Residents of Cleveland, Ohio, were just subjected to a redistricting exercise. I say subjected to because very few of them participated in the exercise. The last census triggered a charter-mandated remapping of ward boundaries, and, given the population decline, city council is to be reduced by two seats. The need for this had been in front of city leaders since census results were released, but there was no comprehensive, strategic public engagement process to discuss what factors ought to be taken into account as new ward configurations were considered, no draft maps shared with the public, no clear process for providing input. Instead, Cleveland's city council president worked with consultants behind closed doors and met with his colleagues on council individually to make deals and divvy up the city's population.

It has been said that we live in a time when voters don't pick their representatives; rather representatives pick their voters. In this case, the council president appears to have picked voters for his colleagues.

I don't actually know if this map will be good for Cleveland or not. Nobody knows. Those who voted for the first version of the map have had to backstep a little when Cleveland's small but significant Hispanic community challenged the map as a possible violation of the Voting Rights Act. Now that that detail has been addressed, for all we know, this could actually be the best map we ever could have hoped for. Here's the problem: we'll never know.

With Sunlight`s growing involvement in the global open government movement, we are introducing some of the innovative and interesting open government tools and projects outside of the U.S. We welcome our first international guest blogger, Eva Vozárová, who works as an IT projects manager at the Slovak watchdog NGO Fair-play Alliance. She worked as a journalist for five years at the largest Slovak economic weekly, Trend, before joining FPA. Currently, she mostly works on open data-related activities. Eva will join us at TransparencyCamp next week, and it’s not too late to register for TCamp!

Slightly over a year ago, an important shift happened in the field of access to information in Slovakia. The government of the Prime Minister Iveta Radičová was due to leave office in a couple of weeks. The involved parties lost elections in March 2012 and were soon to be replaced by their opponents.

But in a final move before going out of business, the Cabinet Office decided to make a push for openness in Slovakia and launched an official governmental data portal at data.gov.sk. The whole process took about a month and was greatly helped by OKFN and their CKAN platform, which was used to power the portal. For the first time, Slovak government made a commitment to publish data proactively, systematically and in machine readable formats.

True, the data was not of very good quality at the beginning. Even now, a year later, it is still lacking in several aspects. The formats are often inconsistent, often linking to plain .html websites. The licensing is not sorted out at all with public licenses not being available under Slovak copyright law. And some of the most interesting datasets are still stuck in the process of being published. But anyway -- the shift happened and the data is slowly being released.

It was to a great extent thanks to the work of Slovak Civil Society Organizations (CSOs) that this shift happened at all. The Fair-play Alliance started working with data 10 years ago. In 2003 we first started requesting public data through FOIA requests, collecting it and analyzing it. Since then, we created an extensive database of public information called Datanest.sk -- a website storing loads of information about flows of public money in Slovakia (subsidies, EU funds, funding of political parties). In short, a website filled with as much corruption-related data as you can possibly get in Slovakia. The data is accessible and searchable through the web and is also available through a simple API. It’s far from perfect and it has been a long time in the making, but it was available long before the state started publishing its own data and even today, Datanest is still the only source to have published several interesting datasets.

The reason why we originally decided to go for data was pretty simple. As a watchdog organization made up of several former journalists, we wanted to focus on anti-corruption advocacy through publishing of corruption-related cases. In order to prepare these stories properly, we needed to look at hard evidence - and getting the data about public finances was simply the best way to go about it.

One of the great challenges for political activism in each of the 50 state legislatures is providing timely information on bills as they move through the legislative process. The data provided by the Sunlight Foundation Open States API is comprehensive, but combing through it to find the limited number of bills that activists have the time to focus on can be overwhelming. I have found over 88,000 bills in the current session alone. We are now developing an early warning system at UniteBlue.com that can assist our volunteers in filtering this information flow down to a manageable level.

While the entire process will take months to complete, in this guest post I’d like to propose a triage model that can be used as a first step. Triage is the medical model used in hospital emergency rooms and during disaster responses. A high flow of patients is screened using certain “signatures” to determine which ones need to be seen first, such as blocked airways or dangerous vital signs. The process of triaging the high flow of bills coming from the Sunlight data will follow a similar model.

Rodney Bent is a U.S. Advisory Committee Member of Publish What You Fund -- a global campaign for aid transparency. He spent most of his career with the US government, including more than 20 years with the Office of Management Budget, as well as time at the State Department and the Millennium Challenge Corporation.

Over the past 18 years, the American public told pollsters they believe the U.S. government spends way too much on foreign aid, reckoning that something like a fifth or a quarter of the federal budget is used for that purpose.

That, of course, is not true. It’s really “just” one percent of the budget, or more than $50 billion. That’s still a lot of money. Senator Everett Dirksen might never have said “a billion here, a billion there, and pretty soon you’re talking real money,” but here we are talking real money. What does the U.S. taxpayer get for that $50 billion?

It’s hard to know. It should not be.

On January 21, 2009, President Obama said his Administration was committed “to creating an unprecedented level of openness in Government.” I’d wager that he has done just that – the frontier of knowledge and the boundaries of available data have been pushed out. It is unprecedented, and for that, two cheers.

The Administration needs to do more to earn that third cheer. Unprecedented doesn’t mean good enough.

Sy Syms, the legendary discounter, had it right: “An educated consumer is our best customer.” Transparency in all government spending is essential but transparency in foreign assistance spending is critical. Foreign aid spending is never popular in Congress. American taxpayers, with respect to foreign aid, are neither educated consumers nor good customers. The executive branch should help in the education by being much more transparent in what it does with foreign assistance.

Pam Selle is a News Apps Developer and Community Evangelist for AxisPhilly, a nonprofit investigative news organization that prioritizes work in the public interest. She is a resident of Philadelphia, speaks at national and regional technical events, and blogs at thewebivore.com. Follow her at @pamasaur.

Philadelphia is known as a leader in the open government movement – the city lays claim to the second Chief Data Officer in the country (Sunlight OpenGov Champion Mark Headd), is a two-time Code for America host city, is home to an active Code for America Brigade and has social good hackathons at least every month, sometimes every week. There’s a strong interest in creating applications to inform and empower citizens with apps such as Lobbying.ph, PhillySNAP and Baldwin using public data for their respective purposes.

In February, the city released the AVI calculator, an online app that helps residents determine real estate taxes under a new policy that went into effect. The city also made the data powering the calculator available as an API. This allowed AxisPhilly, an independent, nonprofit news organization, use the AVI calculator API and transform it from just informational to a discussion tool.

The website appsforphilly.org, which lists open source projects in Philadelphia, lists these two projects side by side. So how did a city government and a news organization end up next to each other on this list of open source projects? What’s the story behind Philadelphia making a web app and releasing the data to enable tools like AxisPhilly’s? For one, both projects are open source and allow for code-sharing. You can access the code for both the City of Philadelphia’s AVI project and AxisPhilly’s map project template on GitHub. AxisPhilly’s project also leverages the property parcels open data set.

Tom Meagher is the co-founder of Hack Jersey and the data editor at Digital First Media's Project Thunderdome in New York City. His team builds interactive news applications, supports computer-assisted reporting projects in local newsrooms and offers training. He served as the data editor for The Star-Ledger in Newark, and he lives with his family in suburban New Jersey. Reach him at @ultracasual or @hackjersey.

Wrapped by the hanging air quotes of New York City and Philadelphia, New Jersey's history of invention and investigative reporting tends to get overlooked. Even within the state, the two disciplines haven't acknowledged each other much. In recent years, there've been hackathons at local colleges or tech groups, but the Garden State's journalists never really mingled with programmers or dipped their toes into building news applications. Until now.

This winter, Hack Jersey held the state's first news hackathon and attracted dozens of journalists and developers to learn from and compete with one another. Sponsored by the NJ News Commons, Knight-Mozilla's OpenNews and many other organizations, the hackathon revolved around a simple (and maybe obvious) idea. By bringing coders and journalists together to use public data and solve problems, we could sow the seeds for an amazing new community here.

On April 20, CityCamp returns to Kansas City for its second year. Based on the popular series created by Code for America alumnus Kevin Curry and inspired by the Sunlight Foundation’s own TransparencyCamp, CityCampKC is a day long unconference at the nexus of community, government and technology in Kansas City.

Last year’s event focused on open source and open data, helping to drive communication and innovation within local government in the Kansas City region. Things will be a bit different than last year, but trust us, that’s a good thing! Instead of a predefined speaker list, sessions will be programmed by attendees and will emphasize the increasing diversity in government, government technology and civic engagement. Specifically, trying to balance gender, race and age cohorts involved in the conversations that shape the city. This year, discussion topics will be chosen the morning of the event and can be suggested by anyone!

Passionate about something in the KC community? Come share it and inspire others to get excited too!
