At the heart of the battle were two document formats, one called ODF, developed by OASIS, a standards development consortium, and Open XML, a specification developed by Microsoft. Both were submitted to, and adopted by, global standards groups ISO/IEC. But then Microsoft never fully adopted its own standard. Instead, it implemented what it called "Transitional Open XML," which was better adapted for use in connection with documents created using older versions of Office. Yesterday, Microsoft announced In a blog entry — http://tinyurl.com/c5ppkwz — that it will finally make it possible for Office users to open, edit and save documents in the format that ISO/IEC approved."
