From Kim Cameron:
"Microsoft announced a new initiative that I hope goes a long way towards making life easier for all of us working together on identity cross-industry.
It’s called the Open Specification Promise (OSP). The goal was to find the simplest, clearest way of assuring that the broadest possible audience of developers could implement specifications without worrying about intellectual property issues - in other words a simplified method of sharing “technical assets”. It’s still a legal document, although a very simple one"
This is an important move on the identity architecture front. Kim subsequently points to the range of reactions to the move on his blog.
