"We have updated and expanded upon the Sebastopol list and identified ten principles that provide a lens to evaluate the extent to which government data is open and accessible to the public. The list is not exhaustive, and each principle exists along a continuum of openness. The principles are completeness, primacy, timeliness, ease of physical and electronic access, machine readability, non-discrimination, use of commonly owned standards, licensing, permanence and usage costs. "

"More recently, I've used the same data to make my subjects more consistent and up to date. In this post, I'll describe why I need to do this, and why doing it isn't as hard as I feared that it might be."

"But the Library of Congress (LC) has recently made authoritative subject cataloging data freely available on a new website. There, you can query it through standard interfaces, or simply download it all for analysis. I recently downloaded their full data set (38 MB of zipped RDF), processed it, and used it to build new subject maps for The Online Books Page. The resulting maps are substantially richer than what I had before. My collection is fairly small by the standards of mass digitization- just shy of 40,000 items- but still, the new data, after processing, yielded over 20,000 new subject relationships, and over 600 new notes and explanations, for the subjects represented in the collection."

The key issues according Peter Murray-rust: * What is data? * Why should data be open? (and when should it not be?) * Who owns data? * When should data be released? * How and where should data be exposed? * Datamining and textmining. * Reproducibility.

"This article reviews the need for Open Data, shows examples of why Open Data are valuable and summarizes some early initiatives in formalizing the right of access to and re-use of scientific data."

the approach to open and linked data in the context of the UK Government, the emergence data.gov.uk as part of the previous administration's Making Public Data Public initiative; and the subtle change of emphasis accompanying the new administrations name change to the Transparency Programme.

"Clearly data release can reduce fraud and curb unnecessary spending. The MPs' expenses scandal has stimulated more interest in this area but there are already websites dedicated to examining how public money is spent. Releasing full financial breakdown of spend can save millions, as a recent case in Canada proved. A $3.2 billion tax evasion fraud was exposed when financial data was made publicly available."

"In my humble opinion, there are two main reasons to be cautious: 1. Contests so far have generated relatively few ideas, most of which either relate to the realm of politics (e.g. how to map funding to politicians to what they do) or to relatively narrow areas, such as crime-related information. I have not yet seen anything extraordinary that would have a significant impact on service levels. 2. Contestants are necessarily either professional programmers, working for a vendor or self employed, or geeks. My contention is neither category is very likely to be hugely representative of the public at large."

"As I wrote in the past, wearing my typical analyst cynical hat, response to these contests has not been overwhelming. Sure we have seen a handful of original ideas, but often far from being ready for prime time, or difficult to sustain in the longer term."

"The business model we're imposing on top of this two-fold: * Some features of the system, such as personal dashboards, scheduled email reports and API access is only available to paying subscribers. * Access to premium data, such as market research, financial market data and analyst forecasts is sold for a fee. As the company name implies, this is a market for data, even though a lot of the "merchandise" is free of charge."

"We believe it's much better to publish the following five components to provide transparent and auditable disclosure: 1. The raw data 2. The circumstances of its collection 3. The method and assumptions used to process the data (in words and equations) 4. The results of the processing 5. The known limitations on the method and significance of the assumptions"

""Yes, but what do I actually have to do to publish my data?" In an attempt to simplify the answer to that oft unuttered question, I break things down in to three steps. Step 1 Get your Data Out Step 2 Get your Data In Step 3 Link it all about "

"HelMet-kirjastot ja BTJ Finland Oy ovat sopineet pilottihankkeesta, jossa BTJ:n luettelointipalvelun käyttöoikeutta laajennetaan HelMetin avoimen datan hankkeeseen. Vuoden 2011 loppuun jatkuvassa pilottihankkeessa HelMet voi luovuttaa edelleen vapaasti BTJ:n toimittamia tietueita kuuden kuukauden karenssiajan jälkeen."

"One missed opportunity was to shine the spotlight on the principle of "openness" as a guiding principle. In recent years, an open approach has found increasing favour for a broad range of technology policy issues and has been incorporated into many strategy documents. For example, New Zealand identified "openness is a central principle of [its] Digital Strategy 2.0."

"Universities could be adding millions of pounds to the UK economy, according to findings announced this week by JISC at a Universities UK event. A recent JISC report, authored by Alma Swan (Modelling scholarly communication options: costs and benefits for universities) shows that a single large university could contribute around £3 million each year to the research community as a whole simply by sharing knowledge through a more open route."

"Today PSI reuse happens very, very, very seldom and this produces all kinds of paradoxes and waste: there are PAs that pay private companies for packaged versions of the data that they themselves produced and licensed very cheaply to those companies, citizens that cannot see or must pay to see data they paid for with their taxes, small businesses that sometimes can't even start because they'd need data that should be public and free but aren't."

"To help governments open and share their data, the W3C eGov Interest Group has developed the following guidelines. These straightforward steps emphasize standards and methodologies to encourage publication of government data, allowing the public to use this data in new and innovative ways."

"While the Open Data movement has yet to demonstrate its killer app, it shows much promise. It will take commitment from both innovators and the city governments to sustain the momentum over the year, but these early successes suggest that open API's and killer coders may be able to revolutionize the way cities operate and interact with their citizens."

"Using the success of the iPhone project and the increasing number of good open data examples (e.g. http://data.gov.uk) we were able to kick-off our own open data project to create opendata.warwickshire.gov.uk. The business case and main benefits driving the project are: * Transparency for the public * Enhancing public communications * Improving service delivery and enabling citizens to self-serve * Contributing towards new ways of running public services * Improving external contribution to WCC * Enabling mash-ups of disparate sources of information to create new ways of looking at information * Enabling 3rd sector organisations or individuals to develop applications aggregating data across organisational boundaries * Reducing workload in areas like Freedom of Information (FOI), the Observatory and Public Relations * Reinforcing our efforts to resolve data and information issues"

"Apps for the Army is the Army's first application development challenge, and one of the first done by the federal government. Recently, as part of the Open Government Directive, the Obama administration encouraged agencies to involve the public in challenges and contests to develop content and ideas for government and provided guidance for running these challenges."
