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.} } @conference {Teixeira:2014:UCO:2641580.2641627, title = {Understanding Coopetition in the Open-Source Arena: The Cases of WebKit and OpenStack}, booktitle = {Proceedings of The International Symposium on Open Collaboration}, series = {OpenSym {\textquoteright}14}, year = {2014}, pages = {39:1{\textendash}39:5}, publisher = {ACM}, organization = {ACM}, address = {New York, NY, USA}, abstract = {In an era of software crisis, the move of firms towards distributed software development teams is being challenged by emerging collaboration issues. On this matter, the open-source phenomenon may shed some light, as successful cases on distributed collaboration in the open-source community have been recurrently reported. In our research we explore collaboration networks in the WebKit and OpenStack high-networked open-source projects, by mining their source-code version-control-systems data with Social Network Analysis (SNA). Our approach allows us to observe how key events in the industry affect open-source collaboration networks over time. With our findings, we highlight the explanatory power from network visualizations capturing the collaborative dynamics of high-networked software projects over time. Moreover, we argue that competing companies that sell similar products in the same market, can collaborate in the open-source community while publicly manifesting intense rivalry (e.g. Apple vs Samsung patent-wars). After integrating our findings with the current body of theoretical knowledge in management strategy, economics, strategic alliances and coopetition, we propose the novel notion of open-coopetition, where rival firms collaborate with competitors in the open-source community. We argue that classical coopetition management theories do not fully explain the competitive and collaborative issues that are simultaneously present and interconnected in the WebKit and OpenStack open-source communities. We propose the development of the novel open-coopetition theory for a better understanding on how rival-firms collaborate with competitors by open-source manners. }, keywords = {COLLABORATION, Competition, Coopetition, Ecosystems, FLOSS, Open-Coopetition, open-source, OSS, Strategic Alliances}, isbn = {978-1-4503-3016-9}, doi = {10.1145/2641580.2641627}, url = {http://doi.acm.org/10.1145/2641580.2641627}, author = {Teixeira, Jose} } @proceedings {1455, title = {Open-Source Technologies Realizing Social Networks: A Multiple Descriptive Case-Study}, volume = {378}, year = {2012}, month = {09/2012}, pages = {250-255}, publisher = {IFIP AICT, Springer}, abstract = {This article aims at describing the role of the open-source software phenomenon within high-tech corporations providing social networks and applications.

Our findings, based on a population of three commercial providers of social networks a suggest that open-source plays an important role on the technological development of their social networking platforms. An open-source technological stack for realizing social networks is proposed and several managerial issues dealing with collaboration with open-source communities are explored.}, keywords = {entrepreneurship, facebook, netlog, social networks, spotify}, author = {Teixeira, Jose} }
