The OpenDocument Foundation has designed a plug-in that will add full support for its OpenDocument Format (ODF) from within the Microsoft Office productivity suite.
ODF is an open-source document format which recently achieved ISO accreditation.
The plug-in, which is not yet publicly available, will soon be submitted to the US state of Massachusetts, which is planning to use ODF as a standard file format.
Massachusetts is gradually migrating away from the proprietary file formats found in the Microsoft Office.
It wants to make sure its data is not locked into such applications, and that it can freely distribute information without having to re-negotiate software licences.
Microsoft, concerned that other organisations may follow Massachusetts, is making some of its application file formats more open to help convince users it has no intention of locking anyone in.
