Partly right. The MS plan is actually much bigger than Brian Profitt suggests. The MSOffice 2007 SDK is fille dwith new API's, the most interesting of which are the ones connecting MSOffice to XAML and the Windows Presentation Foundation layer. The killer component though is the OOXML <> fixed/flow translator component with related API's.

fixed/flow is a new web format that is 100% proprietary. It's at the heart of the Microsoft cloud, enabling developers to easily transition between OOXML and IE browsers able to serve fixed/flow pages to devices, desktops and just about any kind re purposing publication - content management system imaginable.

If ISO approves OOXML, then they've standardized MSOffice as a legitamate Web editor - enterprise publication, content management, archive management front end. Instead of producing W3C compliant (X)HTML - CSS web pages though, the MSOffice Web editor will produce the proprietary fixed/flow format via the OOXML translation component we can now see in the SDK.

What we don't see in the MSOffice SDK is the use of W3C technologies such as (X)HTML, CSS, SVG, XForms, SMiL, XSL, XSL-FO. Instead of Mozilla XUL or Adobe Flex, we find XAML and Silverlight.

IMHO, Microsoft is making their run for the Web. Key to this run is ISO approval of OOXML. Once that happens, there will be no need for MS product compliance with W3C standards. The break will be complete. The We forever split into the Windows Web, and the Firefox - Apache Tomcat Web. And never the twain shall meet.

OOXML, or to put it more accurately "O12X" as Tim suggests, is designed to capture the exact semantics of MSOffice 12. In fact, OOXML is an XML encoding of the MSOffice 12 in-memory-binary-representation dump. When it comes to representing older versions of MSOffice documents, OOXML must use legacy compatibility settings" to capture the semantics. And it's not an exacting science to say the least.

The thing is, OpenOffice ODF uses the same technique resulting in application specific ODF documents with over 150 un docuemnted, unspecified "compatibility settings". After years of requests from the OASIS ODF Technical Committee to document these application specific settings, Sun has yet to provide any kind of response. And this kills ODF interoperability. Especially concerning KOffice.

There is also the issue of OASIS ODF high-jacked namespaces. When ODF applications reference a namespace, the actual URL is high-jacked with http://oasis-open.org/???? replacing the proper namespace of http://W3C.org/????

This high-jacking impacts the oDF reuse of important W3C technologies such as XForms, SVG, MathML, and SMiL.

So where's the problem you ask? Well, when a developer imports or tries to process an OpenOffice ODF document, they rely on say the W3C XForms specification for their understanding. OpenOffice however seriously constrains the implementation of XForms, SVG, MathML, RDFa and RDF/XML. This should be reflected in the new namespace. However, if you follow the high-jacked URL, you'll find that there is nothing there. There is no specification describing how OpenOffice implements XForms in ODF! This breaks developer libraries, breaks ODF interoperability between ODF applications, and, offends the W3C to no end.

So i think it might be fair to say that at this point, neither ODF or OOXML have come close to fulfilling their design objectives.

Exactly!! Except for one thing that Tim misses: the presentation layers of both ODF and OOXML are application specific. It is also the application specific nature of OpenOffice ODF presnetation layer that prevents interoperability with KOffice ODF!

There is near zero interop between OpenOffice and KOffice, and KOffice has been a contributing member of the OASIS ODF TC for FIVE YEARS!

It's the presentation layer Tim. ODF and OOXML are application specific formats because their presentation layers are woefully applicaiton specific and entirely reflective of each applications layout engine and feature set implementation model.

I often imagine what ODF would be like if back in 2001, Sun had chosen to implement CSS as the OpenOffice presentation layer instead of the quirky but innovative, and 100% application specific automatic-styles presentation layer we now see in ODF.

Unlike ODF's "automatic-styles", CSS is a totally application independent presentation model prized exactly for it's universal interoperability!

Bingo! ODF and OOXML should strip off the application specific complexities and seek a neutral generic XML representation of basic document structures common to ALL documents. Then, use the XML NameSpace mechanism to extend (with proper descriptions) the generic to include the volumes of application specific features that now fill each format.

One thing i disagree with Tim about. And that's that the interop of ODF and OOXML is hopelessly broken. The OpenDocument Foundation tried for over a year to close the compatibility gap between ODF and MSOffice binary - xml documents. The OASIS ODF TC would have none of it. IBM and Sun are set on a harsh course of highly disruptive and costly rip-out-and-replace of MSOffice based on government mandates for ODF. There is no offer of compromise to be had.

On the Microsoft side, even if they did want to compromise (a big IF), there is that problem of over 550 million MSOffice workgroup-workflow desktops to contend with. The thing is, the only way to harmonize, merge, convert or translate between two application specific formats is to actually harmonize the applications themselves. While the generic subset is a worthy goal, the process would be fraught with real world concerns that the existing application workflows are not disrupted.

My proposal? Demand that ODF and OOXML application vendors provide format options for PDF, and the W3C's family of formats: (X)HTML5, (X)HTML - CSS, and CDF (XHTML-CSS-XForms-SVG-SMil-MathML). That will do it.

We might never see the quality of interoperability we had hoped for in a desktop application to application scenario. But we can and should fully expect high quality interop at the higher level of the Web. You can convert an application specific format to a generic like CDF. By setting up conversion channels to the same CDF profile within MSOffice, OpenOffice, KOffice, Symphony, and Google Docs, we can achieve the universal interoperability we had hoped to see but will never get from ODF and OOXML.

Works for me!
