Fortunately for Microsoft, the DaVinci plugin is coming, which will enable Microsoft office applications to comply with ISO 26300. We all understand the financial issues that prompted the push to make OOXML a standard (see Tim's comment above and http://lnxwalt.wordpress.com/2007/01/21/whose-finances-are-on-the-line/ for more on this) and ensure continued vendor lock-in. However, OOXML is not the answer.

ODF can handle everything and anything Microsoft Office can throw at it. Including the legacy billions of binary documents, years of MSOffice bound business processes, and even tricky low level reaching add-ons represented by assistive technologies.

Opponents to OOXML, which include IBM (Quote) and the Open Document Foundation, have argued that Microsoft's specifications are unwieldy and that the standard application is redundant with the Open Document Format (ODF), which already exists. Microsoft has countered that the OOXML format is valuable because it is closer to Office 2007 and is backwards-compatible with older versions of Office. "Although both ODF and Open XML are document formats, they are designed to address different needs in the marketplace," the company wrote in an open letter published earlier this month.

# re: Office Open XML final draft!!! @ Wednesday, October 11, 2006 1:46 PM The past incarnations of DrawingML have been chaotic. It would be interesting, out of curiosity, to get an accurate history of what changed over time, perhaps to better understand what is supported in what. Here is my take, I am pretty sure I got at least 50% of it wrong :-) - pre-Windows 95 era, Word, Excel and Powerpoint use their own vector drawing layer used to draw shapes, pictures, diagrams, art and charts. Powerpoint, acquired by Microsoft in 1987, has by far the advanced drawing layer (bi-linear gradients, opacity, ...), codenamed Escher (in reference of the famous mathematician). - In Office 95, it is decided to reuse the Powerpoint vector graphics layer in Word and Excel. Migration begins. - Migration ends with Office 97 where both Word, Excel and Powerpoint use the same vector graphics layer, publicly known as MSO (mso97.dll) - In Office 2000, it's all craze about internet and Word tries to export WYSIWYG html. For that end, mark up extensions must be added to account for the MSO drawing layer. Hence the VML (Vector Markup language). Excel and Powerpoint don't support it. Internet Explorer natively supports VML (Internet Explorer's Direct animation vector drawing layer dismissed for performance reasons). - In Office XP, VML migration ends and both Word, Excel and Powerpoint support VML whenever a document is saved as a "Single web page archive" (.mhtml extension). - In Office 2003, nothing changes. - In Office 12, MSO gets rewritten with backwards compatibility in mind. The vector drawing layer uses more sophisticated drawing functionalities which makes it easier to draw themed, 3D realistic  objects. Technically, the differences are akin to the differences between GDI and GDI+. This new shared library is known as E2O and the corresponding mark up language is known as Drawing ML (Ecma TC45 specs). - In Office 14, ??? perhaps the drawing layer is rewritten, again, to 1) use WPF 2) to allow plugins, hence enabling much more sophisticated do-it-yourself scenarios. Use cases : custom charts ; BI analysis tools. Stephane Rodriguez
