Everything changes over time, from the constitutions of nations to political theories. Should the Open Source Software Definition be any different? Earlier this week the Board of Directors of the Open Source Initiative issued an Affirmation of the Open Source Definition, inviting others to endorse the same position. The stated purpose of the release was to underline the importance of maintaining the open source software (OSS) definition in response to what the directors see as efforts to ???undermine the integrity of open source.??? Certainly, that definition has stood the test of time, and OSI has ably served as the faithful custodian of the definition of what can and cannot be referred to as OSS. That said, while well-intentioned, the statement goes too far. It also suggests that the directors would do well to reflect on what their true role as custodians of the OSS definition should be.
