Microsoft Corporation plans a formal standard for its Office productivity applications and Ecma International accepted the Microsoft application. Ecma created Technical Committee 45 (TC45) to produce a formal standard of office productivity applications which is compatible with the Office Open XML Formats.
The Open XML standard will make Office compatibility easier for competing desktop application suites such as Sun Microsystems branded StarOffice and OpenOffice.org. Microsoft released Office 2003 schemas in late 2003. In June, 2005 the company said they planned to make the new XML file formats the default in Office "12" and available to anyone under a royalty-free license.
