Meanwhile, six companies including both mobile phone carriers and manufacturers started the LiMo Foundation in 2007, defined the API specifications and published the Beta version of the specifications in February 2008. The LiMo Foundation plans to continue its efforts in promoting construction of Linux OS-based platform for mobile terminals and in building so-called “ecosystem.” Keywords mobile terminal, software platform, Linux, LiMo Foundation, ecosystem vice software platforms. 1.

Open Source, Modular Platforms, and the Challenge of Fragmentation Christopher S. Yoo* Abstract Open source and modular platforms represent two powerful conceptual paradigms that have fundamentally transformed the software industry. While generally regarded complementary, the freedom inherent in open source rests in uneasy tension with the strict structural requirements required by modularity theory. In particular, third party providers can produce noncompliant components, and excessive experimentation can fragment the platform in ways that reduce its economic benefits for end users and app providers and force app providers to spend resources customizing their code for each variant. -

Open Source, Modular Platforms, and the Challenge of Fragmentation
THE C RITERION J OURNAL ON I NNOVAT I ON Vol. 1 E E E 2016 Open Source, Modular Platforms, and the Challenge of Fragmentation Christopher S. Yoo* Open source and modular platforms represent two powerful conceptual para- digms that have fundamentally transformed the software industry. Although generally considered complementary, the freedom inherent in open source rests in uneasy tension with the strict structural requirements of modular- ity theory. In particular, third-party providers can produce noncompliant components, and excessive experimentation can fragment the platform in ways that reduce its economic benefits for end users and app providers and force app providers to spend resources customizing their code for each variant. The classic solutions to these problems are to rely on some form of testing to ensure that the components provided by third parties comply with a compatibility standard and to subject the overall system to some form of governance. The history of the three leading open source operat- ing systems (Unix, Symbian, and Linux) confirms this insight. The question is thus not whether some constraints will apply, but rather how restrictive those constraints will be. Finally, the governance regimes range from very restrictive to relatively open and permissive. Competition policy authorities should take into account where certain practices fall along that spectrum when enforcing competition law. Exposing the more permissive practices to demanding scrutiny runs the risk of causing operating systems to turn to more restrictive approaches. * John H.
