“…Similarly, it suggests the possibility of developing computational tools or interactive architecture development environments that can be used to specify, model, and analyze a software system's security architecture at different times in its developmentdesign-time, build-time, and run-time. The approach we have been developing for the past few years for modeling and analyzing software system IP license architectures for OA systems (Alspaugh, Asuncion, & Scacchi, 2009bScacchi & Alspaugh, 2008) may therefore be extendable to also being able to address OA systems with heterogeneous "software security license" rights and obligations. Furthermore, the idea of common or reusable software security licenses may be analogous to the reusable security requirements templates proposed by Firesmith (2004) at the Software Engineering Institute.…”

“…With this information and definitions of the licenses involved, we believe it is possible to automatically calculate rights and obligations for individual components or for the entire system, as well as guide/assess system design and evolution, using an automated environment of the kind that we have previously demonstrated (Alspaugh, 2009a(Alspaugh, , 2009b.…”

“…Due to the complexity of license architecture analysis, and the need to re-analyze every time a component evolves, a component's security license changes, a component is substituted, or the system architecture changes, OA integrators really need an automated license architecture analysis environment. We have developed a prototype of such an environment for analogous calculations for software copyright licenses (Alspaugh, Asuncion, & Scacchi, 2009b;, and are extending this approach to security licenses.…”

The research presented at the symposium was supported by the Acquisition Chair of the Graduate School of Business & Public Policy at the Naval Postgraduate School. in its first seven years. The sheer volume of research products-almost 600 published papers (e.g., technical reports, journal articles, theses)-indicates the extent to which the depth and breadth of acquisition research has increased during these years. Over 300 authors contributed to these works, which means that the pool of those who have had significant intellectual engagement with acquisition issues has increased substantially. The broad range of research topics includes acquisition reform, defense industry, fielding, contracting, interoperability, organizational behavior, risk management, cost estimating, and many others. Approaches range from conceptual and exploratory studies to develop propositions about various aspects of acquisition, to applied and statistical analyses to test specific hypotheses. Methodologies include case studies, modeling, surveys, and experiments. On the whole, such findings make us both grateful for the ARP's progress to date, and hopeful that this progress in research will lead to substantive improvements in the DoD's acquisition outcomes.As pragmatists, we of course recognize that such change can only occur to the extent that the potential knowledge wrapped up in these products is put to use and tested to determine its value. We take seriously the pernicious effects of the so-called "theorypractice" gap, which would separate the acquisition scholar from the acquisition practitioner, and relegate the scholar's work to mere academic "shelfware." Some design features of our program that we believe help avoid these effects include the following: connecting researchers with practitioners on specific projects; requiring researchers to brief sponsors on project findings as a condition of funding award; "pushing" potentially high-impact research reports (e.g., via overnight shipping) to selected practitioners and policy-makers; and most notably, sponsoring this symposium, which we craft intentionally as an opportunity for fruitful, lasting connections between scholars and practitioners.A former Defense Acquisition Executive, responding to a comment that academic research was not generally useful in acquisition practice, opined, "That's not their [the academics'] problem-it's ours [the practitioners']. They can only perform research; it's up to us to use it." While we certainly agree with this sentiment, we also recognize that any research, however theoretical, must point to some termination in action; academics have a responsibility to make their work intelligible to practitioners. Thus we continue to seek projects that both comport with solid standards of scholarship, and address relevant acquisition issues. These years of experience have shown us the difficulty in attempting to balance these two objectives, but we are convinced that the attempt is absolutely essential if any real improvement is to be realized.We gratefully ...

“…Mods tend to be licensed using OSS or freeware licenses that allow for access, study, modification, and redistribution, rather than using free software licenses (e.g., GPLv2 or GPLv3). Software extensions that might be subject to a reciprocal GPL style license require that the base/original software system incorporate an explicit software architectural design that requires the propagation of reciprocal rights across an open interface, except through an LGPL software shim [1]. Otherwise, the scope of effectiveness and copyright protections of either free or nonfree software (or related media assets) cannot be readily determined, and thus may be subject to copyright infringement or licenses non-compliance allegations.…”

Abstract. This paper examines what is known so far about the role of open source software development within the world of game mods and modding practices. Game modding has become a leading method for developing games by customizing or creating OSS extensions to game software in general, and to proprietary closed source software games in particular. What, why, and how OSS and CSS come together within an application system is the subject for this study. The research method is observational and qualitative, so as to highlight current practices and issues that can be associated with software engineering and game studies foundations. Numerous examples of different game mods and modding practices are identified throughout.

Thomas Alspaugh-Thomas Alspaugh is adjunct professor of computer science at GeorgetownUniversity and visiting researcher at the Institute for Software Research at UC Irvine. His research interests are in software engineering and software requirements. Before completing his PhD, he worked as a software developer, team lead, and manager in industry and as a computer scientist at the Naval Research Laboratory on the Software Cost Reduction project, also known as the A-7E project.Hazel Asuncion-Hazel Asuncion is a postdoctoral scholar at the Institute for Software Research.Starting Fall 2010, she will be an assistant professor in the Department of Computer Science at the University of Washington, Bothell. Her research interests focus on traceability, process workflows, software system architectures, and their interrelationships. AbstractThe role of software ecosystems in the development and evolution of open architecture systems has received insufficient consideration. Such systems are composed of heterogeneously licensed components, open source or proprietary or both, in an architecture in which evolution can occur by evolving existing components or by replacing them. But this may result in possible license conflicts and organizational liability for failure to fulfill license obligations. We have developed an approach for understanding and modeling software licenses, as well as for analyzing conflicts among groups of licenses in realistic system contexts and for guiding the acquisition, integration, or development of systems with open-source components in such an environment. This work is based on empirical analysis of representative software licenses and heterogeneously licensed systems, and collaboration with researchers in the legal world. Our approach provides guidance for achieving a "best-of-breed" component strategy while obtaining desired license rights in exchange for acceptable obligations.
