Open Document Format War

This is a good time for me to write again in my blog. Today I read the news about ODF-OOXML that was issued together by Novell and Microsoft. OOXML (Open Office XML) was the product from Novell and Microsoft, whereas ODF (OpenDocument Format) from the OpenOffice community. The two fortifications also issued each other converter for the two formats. Novell officials said late last year that they planned to create a version of OpenOffice that would include Office Open XML (OOXML) file-format compatibility. The other side, Sun was releasing a plug-in for Microsoft Office 2003 that will allow two-way compatibility with the OpenDocument Format, the company announced on Wednesday. This that made confused the user. Why must make separately the format for the document be open?
