Easy As Abc: Categorizing Open Source Licenses
EASY AS ABC: CATEGORIZING OPEN SOURCE LICENSES Andrew T. Pham1, Matthew B. Weinstein2, Jamie L. Ryerson3 With more than 180,000 open source projects available and its more than 1400 unique licenses, the complexity of deciding how to manage open source usage within “closed-source” commercial enterprises have dramatically increased.4 Because of the complexity and risks associated with open source—where source code is made freely available for all to review, edit, and use—many closed-source commercial enterprises discourage or prohibit use of open source; a common and short-sighted practice. With a proper open source management framework, open source can be an invaluable resource, and its risks can be understood, managed and controlled. This article proposes a simple, consistent and effective open source categorization and management system to enable a peaceful coexistence between open source and closed-source codes. Free and open source software (“FOSS” or collectively “open source”) is a valuable tool, but one that must be understood to be used effectively. The litany of risks associated with use of open source include: having to release a derivative product incorporating open source under the same open source license; incorporating code that infringes a patent; violating an open source license’s attribution requirements; and a lack of warranties and indemnities. Given the extensive investment of time, money and resources that goes into product development, it comes as no This article is an edited version of the original, which dealt not only with categorizing open source licenses but also a wider array of issues associated with implementing an open source policy. -

It provides historical and contextual background for the development of the vidding community, and explores the role of agency among this specialised audience community. Utilising semiotic theory, it offers a theoretical language for understanding the structure and function of remix videos. -
The Economic Evaluation Alternatives to Digital
THE ECONOMIC EVALUATION of ALTERNATIVES TO DIGITAL COPYRIGHT Peter Eckersley Department of Computer Science & Software Engineering and Intellectual Property Research Institute of Australia, The University of Melbourne SERCIAC 2003 (Preliminary Version) 1 ABSTRACT A certain air of controversy has arisen around copyright law, as a result of its interactions with digital technology. The body of literature claiming that existing copyright laws are economically sub-optimal is growing rapidly. Some authors are even claiming that it would be better to have no copyright system at all, while others argue that alternatives, such as various forms of public funding, would be preferable to exclusive rights in literary and artistic works. This paper explores the economic differences between a system of consumer-regulating copyright based on “digital rights management”, and alternatives based on public funding. I argue that the distinctions are sufficiently intricate that they elude any simple modelling technique. Instead, this paper attempts a semi-analytic comparison which weighs a set of different factors which may favour either copyright or the alternatives. When these are summed, it is concluded that well-designed systems of public funding are almost certain to produce better social welfare outcomes than DRM-based copyright. 2 1 Introduction The infrastructure for purely digital information economies is only beginning to crystallise1. As this occurs, it has become apparent that some of the central assumptions which have defined information industries in the past are in danger of unravelling. Perhaps the most prominent assumption of this kind is that states of artificial scarcity will be maintained by the exclusive rights of copyright law (in combination with “digital rights management”). -

Primavera De Filippi & Peter Troxler [4] From material scarcity to arti8cial abundance – The case of FabLabs and 3D printing technologies Primavera De Filippi & Peter Troxler 1. Introduction Digital media allowed for the emergence of new artistic practices and innovative modes of production. In particular, the advent of Internet and digital technologies drastically enhanced the ability for multiple au- thors to collaborate towards the creation of large-scale collaborative works, which stand in contrast to the traditional understanding that artistic production is essentially an individual activity. The signi6cance of these practices in the physical world is illustrated by the recent deployment of FabLabs (Fabrication Laboratories), that employ innovative technologies – such as, most notably, 3D printing, which is recently gaining the most interest – to encourage the development of new methods of artistic production based on participation and interaction between peers. -

Panayiota Georgopoulou* Abstract: At a time when private companies are inventing methods of “locking information” and when neo-liberal governments are imposing strict sanctions on those who violate intellectual property rights, the Free/Open Source Software (FOSS) movement has been countering neo-liberalism and general privatization: it defies ownership regulations in a key area of growth in contemporary capitalistic societies, namely, the construction and use of information. At the end of the ‘90s, FOSS seemed to be a disruptive and destabilizing force in terms of intellectual property and neo- liberalism, yet as open software, it has evolved into a singular economic phenomenon indicating that commercialization -
