	abstract = {Many open source software projects are not very open to third party developers. The point of open source is to enable anyone to fix bugs or add desired capabilities without holding them hostage to the original developers. This principle is important because an open source project{\textquoteright}s developers may be unresponsive or unable to meet third party needs, even if funding support for requested improvements is offered.This paper presents a simple rating system for evaluating the openness of software distributions. The rating system considers factors such as platform portability, documentation, licensing, and contribution policy. Several popular open source products are rated in order to illustrate the efficacy of the rating system.},

	abstract = {The FreeBSD, GNU/Linux, Solaris, and Windows operating systems have kernels that provide comparable facilities. Interestingly, their code bases share almost no common parts, while their development processes vary dramatically. We analyze the source code of the four systems by collecting metrics in the areas of file organization, code structure, code style, the use of the C preprocessor, and data organization. The aggregate results indicate that across various areas and many different metrics, four systems developed using wildly different processes score comparably. This allows us to posit that the structure and internal quality attributes of a working, non-trivial software artifact will represent first and foremost the engineering requirements of its construction, with the influence of process being marginal, if any.},
