t seems we’ve arrived upon Microsoft open source. In the last couple of years, whenever there was discussion of Microsoft’s open source projects and efforts such as CodePlex or Port25, there was typically the standard open source response: it’s not OSI-approved; it’s not real open source.

Today, we reached another milestone with the decision to submit our open licenses to the OSI approval process, which, if the licenses are approved, should give the community additional confidence that the code we’re sharing is truly Open Source.

"The head of the open-source group that will decide whether to certify Microsoft Corp.'s "shared source" software licenses as open-source licenses said that more than half of Redmond's licenses appear to automatically fail the group's rules."

With a bid underway to obtain the blessing of the Open Source Initiative for two of its software licenses, Microsoft is working to burnish its open source credentials.

Industry standards may not be open (e.g., Microsoft Word file formats) so there are reverse-engineering risks with any OSS dependent upon those standards. The MoJ preference for open standards (e.g., Open Document Format, which is now supported even by Microsoft) lessens this risk.

Will Microsoft become more open to open source with the departure of Bill Gates? It’s a tough call. Observers from both the open and closed source worlds say the exit of Microsoft’s longtime leader won’t usher in a GPL era at the company but it will likely accelerate what is already a changing attitude in Redmond.

This week the Dutch government will discuss a proposal to switch as much as possible to open standards and open source software. The Microsoft director for the Netherlands, Theo Rinsema, responded that Microsoft is not objecting to open standards, but the proposal excludes too many not open standards, like PDF, MP3 and GSM, which are widely accepted standards.

"The Open Source Initiative has announced that the OSI Board has approved the Microsoft Public License (Ms-PL) and the Microsoft Reciprocal License (Ms-RL) as satisfying the criteria of the Open Source Definition, following their submission in August..."
