The OSS governance within the big Korean companies significantly developed since several years after 2009. But the level and of governance system thereof is still in ambiguity, because they keep the relevant information on such system confidential and we have few cases that could verify the function and structure of such system. Otherwise, the governmental assistance for OSS governance with the small-medium companies is staying only on the beginning stage.While the technical consulting for OSS governance has been well developed by the compliance tool companies, the legal consulting for it has only three year short history after the setup of KOSS Law Center. The Center has been confronted with two problems; firstly, the passive policy of such big companies not to open their governance, and secondly, lack of legal specialists in OSS area. It may take a little more time to change such policy of big company, while we can get now many fellow candidates from the new beginner lawyers armored with technical background. The government has a very progressive policy to promote OSS with a vision. We have just started to deliberate on establishment of the “KOSS Foundation” as the center of OSS in Korea and Asia, to organize and manage all the technical and legal affairs originated from OSS. In the near future, we wish to have a very well organized governance system to contribute to OSS eco-system world-wide as well as national-wide.
