The Open Source Initiative (OSI) has expanded its board of directors to include representatives from outside the US.

The organisation best known for deciding what is and what is not open source, has expanded the size of its board from five to nine members and added representatives from the Netherlands, Brazil, Sri Lanka, and Taiwan. Long-time member and former president Eric Raymond has stepped down from the board, but will remain involved with the organisation.

The OSI has been struggling lately with the task of reducing the number of different and often incompatible open source licences it has approved.

To date, the OSI has determined more than 50 software licences to be open source compatible, but critics have said that this large number has left some users confused as to whether or not they are following licensing terms. They have called on the organisation to reduce the number of approved licences.

The volunteer group is now forming a committee to find ways to address this issue, and plans to make it more difficult to add licences to the OSI's approved list, board member Danese Cooper said. "There will be more stringent rules for what is an approvable licence."

By adding non-US members to the board, the group hopes to take an "international perspective" to solving the problem, she added.
