The high-competitive mobile devices market, where several players such as Apple, Google, Nokia and Microsoft run a platforms- war with constant shifts in their technological strategies, is gaining increasing attention from scholars. It matters, then, to review previous literature on past platforms-wars, such as the ones from the PC and game-console industries, and assess its implications to the current mobile devices platforms-war. The paper starts by justifying the purpose and rationale behind this literature review on open-source platforms. The concepts of open-source software and computer-based platforms were then discussed both individually and in unison, in order to clarify the core-concept of {\textquotedblleft}open-source platform{\textquotedblright} that guides this literature review. The detailed design of the employed methodological strategy is then presented as the central part of this paper. The paper concludes with preliminary findings organizing previous literature on open-source platforms for the purpose of guiding future research in this area. }, keywords = {Ecosystems, FLOSS, open-source, Platforms, R\&D Management}, isbn = {978-3-642-55127-7}, doi = {10.1007/978-3-642-55128-4_16}, url = {http://dx.doi.org/10.1007/978-3-642-55128-4_16}, author = {Teixeira, Jose and Baiyere, Abayomi}, editor = {Corral, Luis and Sillitti, Alberto and Succi, Giancarlo and Vlasenko, Jelena and Wasserman, AnthonyI.} } @inbook {1615, title = {An Exploration of Code Quality in FOSS Projects}, booktitle = {Open Source Software: Mobile Open Source Technologies}, series = {IFIP Advances in Information and Communication Technology}, volume = {427}, year = {2014}, pages = {181-190}, publisher = {Springer Berlin Heidelberg}, organization = {Springer Berlin Heidelberg}, abstract = { It is a widely held belief that Free/Open Source Software (FOSS) development leads to the creation of software with the same, if not higher quality compared to that created using proprietary software development models. However there is little research on evaluating the quality of FOSS code, and the impact of project characteristics such as age, number of core developers, code-base size, etc. In this exploratory study, we examined 110 FOSS projects, measuring the quality of the code and architectural design using code smells. We found that, contrary to our expectations, the overall quality of the code is not affected by the size of the code base, but that it was negatively impacted by the growth of the number of code contributors. Our results also show that projects with more core developers don{\textquoteright}t necessarily have better code quality. }, keywords = {Code Quality, FOSS, open source software, success metrics}, isbn = {978-3-642-55127-7}, doi = {10.1007/978-3-642-55128-4_26}, url = {http://dx.doi.org/10.1007/978-3-642-55128-4_26}, author = {Ahmed, Iftekhar and Ghorashi, Soroush and Jensen, Carlos}, editor = {Corral, Luis and Sillitti, Alberto and Succi, Giancarlo and Vlasenko, Jelena and Wasserman, AnthonyI.} } @inbook {1598, title = {FOSS Service Management and Incidences}, booktitle = {Open Source Software: Mobile Open Source Technologies}, series = {IFIP Advances in Information and Communication Technology}, volume = {427}, year = {2014}, pages = {76-79}, publisher = {Springer Berlin Heidelberg}, organization = {Springer Berlin Heidelberg}, abstract = { The Free Open Source Software (FOSS) solutions have been reaching a high demand, usage and global recognition, not only in the development of applications for companies and institutions also in the management of services and incidents.
