开源许可证合规性研究

Study of Open-source Software License Compliance

随着开源概念的逐步深入,开源软件成为软件发展的潮流.同时,开源软件的使用受各类开源许可证约束.开源参与者在开发过程中该如何为自己的开源软件选择合适的许可证,确保高效合理地使用社区群体智慧劳动成果,仍是一个亟需解决的问题.为此,首先分析和解读了开放源代码促进会认证的常用开源许可证,通过对许可证条款内容和结构的研究,得到开源许可证框架及许可证兼容性推导模型,并将该模型应用于对我国自主研发的木兰宽松许可证的分析和解读.最后,基于上述工作研发了开源许可证选择工具,为开源开发者对许可证的理解和合规使用提供了参考和决策支持.

With the progresses of open source concept,open source software has become the trend of software development,and the use of open source software is subject to various open source licenses.How open source participants can correctly choose open source software licenses in their development to ensure the efficient and reasonable use of the collaborative results of community groups is still an urgent issue to be solved.To this end,commonly used open source licenses are firstly analyzed and interpreted for OSI certification in the paper.Furthermore,with the studies of the license terms and structure,the open source license framework,and compatibility derivation models are deduced.The model is applied to the analysis and interpretation of Mulan permissive software license independently developed in China.Finally,based on the above work,a license choosing tool for open source license is developed,which provides references and decision support for open source developers to understand and use licenses.
