The Comprehensive Knowledge Archive Network ( CKAN ) is an open-source open data portal for the storage and distribution of open data . Initially inspired by the package management capabilities of Debian Linux, CKAN has developed into a powerful data catalogue system that is mainly used by public institutions seeking to share their data with the general public.
25-537: Since its inception, CKAN has evolved and is the leading open data platform software in the world, used by governments including the US and UK, to publish millions of public datasets. Rufus Pollock developed its first version in 2005-2006. CKAN's codebase is maintained by the Open Knowledge Foundation . The system is used both as a public platform on Datahub and in various government data catalogues , such as

On 24 May 2004 Pollock founded in Cambridge , UK the Open Knowledge Foundation as a global non-profit network that promotes and shares open knowledge including open data and open content - information that is openly and freely available. In 2007 and 2009, Pollock published two important papers regarding

For instance, scholar Neil Netanel argued that Copyright Term Extension Act 1998 prevented the entering of works central to cultural heritage of the US into the public domain. He argued, culturally important dissemination, recasting, or incorporation into new expression is prevented due "to the copyright holder's veto". As examples he gave the adaption of the plot from novels such as The Great Gatsby and Peter Pan ,

In appointing joint stewardship put up jointly by Link Digital and Datopian, the Board felt there was a clear practical path with strong leadership and committed funding to see CKAN grow and prosper in the years to come. The Open Knowledge Foundation will remain the ‘purpose trustee’ to ensure the Stewards remain true to the purpose and ethos of the CKAN project. Rufus Pollock Rufus Pollock (born 1980)

One of the earlier and often cited positions is from the British politician Thomas Babington Macaulay who argued in an 1841 speech in the House of Commons that copyright is a monopoly and as such has generally negative effects on society. Although Macaulay's speech

#1733084907566300-432: The early 20th century there have been a number of adjustments made in various countries, which can make determining the copyright duration in a given country difficult. For example, the United States used to require copyrights to be renewed after 28 years to stay in force, and formerly required a copyright notice upon first publication to gain coverage. In Italy and France, there were post-wartime extensions that could increase

In 2005 he created The Open Definition which provided the first formal definition of open content and open data , and which has remained
350-593: The least objectionable way of remunerating them is by means of copyright. Liebowitz describes use of the term monopoly in relation to copyright as misleading, but "rhetorically effective"; while Towse writes that a more appropriate term is ' monopolistic competition '. In 2009, a paper by Rufus Pollock of University of Cambridge scientifically quantified the optimal copyright term length at 15 years, significantly shorter than any currently existing copyright term, via an economical model with empirically-estimable parameters . In 2013 scholar Petra Moser concluded in
375-546: The optimal copyright term , where he proposed based on an economical model with empirically-estimable parameters an optimal duration of 15 years, significantly shorter than any currently existing copyright term. He has held the Mead Research Fellowship in economics at Emmanuel College , Cambridge . In 2009, he was credited by web inventor Tim Berners-Lee for starting the Raw Data Now meme . In 2010 he

For the millions of older copyrighted works of less enduring popularity, it is difficult, or impossible, to trace the copyright ownership and determine who holds the particular rights that would have to be licensed for the use of
425-459: The right thing and allowed reprinting, however much they abhorred their ancestors' works! It is also worth noting that Macaulay is arguing here against term extension, he is not arguing against copyright. This point is well made by Macaulay himself: The advantages arising from a system of copyright are obvious. It is desirable that we should have a supply of good books: we cannot have such a supply unless men of letters are liberally remunerated; and

A paper published in March 2015 in the Journal of Artificial Societies and Social Simulation analysed with a simulated model the relationship of scientific knowledge creation to copyright term length and concluded
500-613: The term by approximately six years in Italy and up to about 14 in France. Many countries have extended the length of their copyright terms (sometimes retroactively ). International treaties, like the Berne Convention , establish minimum terms for copyrights, but these only apply to the signatory countries, and individual countries may grant longer terms than those set out in a treaty. The extension of copyright term imposes tangible restrictions on
525-412: The work. The problem of such orphan works stems from the extension of copyright term and the lack of requirement for the copyright owner to renew or register their copyright . In order to tackle this perceived problem some jurisdictions have revised their copyright laws to allow use of orphaned works, after diligent searches. Discussions about the optimal length of the copyright term (e.g. regarding

In the United States, the term for most existing works is a fixed number of years after the date of creation or publication. In most countries (for example, the United States and the United Kingdom ) copyright expires at the end of the calendar year in question. The length and requirements for copyright duration are subject to change by legislation, and since
