Uh Oh. Microsoft and Novell joined the EU's call to harmonize ODF and OOXML, but Sun and IBM refused the invite. Now we have the invite in front of the OASIS ODF TC!. Is there any rock big enough for them to hide under if they also refuse?
And if the OASIS ODF does join the EU-DIN-ISO effort, where doe stha tleave IBM, Sun and their inistance on a politically mandated "rip out and replace" as the only acceptable solution?

That there is no specific display for <Cruller> and, especially,
not as distinct from <DonutHole> has been readily understood to
demonstrate the separation of data structure expressed in XML from its display,
which requires the application of styling to accomodate the fixed expectations
of the browser. What has not been so readily accepted is that there should not
be a standard expectation for how a data element, as identified by its markup,
should be processed by programs doing something other than simple
display.

ODF and OOXML are contending to become the Standard Data Vocabulary for desktop office suite XML markup. Sun and Microsoft are proposing the standardization of OpenOffice and MSOffice custom defined XML tags for which there are no standard display expectations. The display expectations must therefore be very carefully described: i.e. the semantics of display fully provided.
In this article Walter Perry is pointing out the dangers of SDV's being standardized for specific purposes without also having well thought out and fully specified display semantics. In ODF - OOXML speak, we would call display presentation, or layout, or "styles".
The separation of content and
Given that the presnetation layers of both ODF and OOXML is directly related to how OpenOffice and MSOffice layout engines work, the semantics of display become even more important. For MSOffice to implement an "interoperable" version of OpenOffice ODF, MSOffice must be able to mimic the OpenOffice layout engine methods. Methods which are of course quite differeent from the internal layout model of MSOffice. This differential results in a break down of conversion fidelity, And therein lies the core of the ODF interoeprability dilemma!

Exactly! When governments mandate a specific SDV, they also are mandating inherent concepts and methods unique to the provider of the SDV. In the case of ODF and OOXML, where the presentation layers are application specific and woefully underspecified, interoperability becomes an insurmountable challenge. Interop remains stubbornly application bound.
Furthermore, there is no way to "harmonize" or "map" from one format to another without somehow resolving the application specific presentation differences.

"in the nature of the SDV's themselves is the problem of misstatement, of misdirection of naive interpretation, and potential for fraud.
Semantics matter! The presentation apsects of a document are just as important as the content.

Walter: "I have argued for years that, on the basis of their mechanism for elaborating semantics, SDVs are inherently unreliable for the transmission or repository of information. They become geometrically less reliable when the types or roles of either the sources or consumers of that information increase, ending at a nightmarish worst case of a third-order diminution of the reliability of information. And what is the means by which SDVs convey meaning? By simple assertion against the expected semantic interpretations hard-coded into a process consuming the data in question.
At this point in the article i'm hopign Walter has a solution. How do we demand, insist and then verify that SDV's have fully specifed the semantics, and not jus tpassed along the syntax?
With ODF and OOXML, this is the core of the interoperability problem. Yet, there really is no way to separate the presentation layers from the uniquely different OpenOffice and MSOffice layout engine models.

Interesting concept here: "the bulk of expertise is in understanding the detail of connections between data and the processes which produced it or must consume it ........ it is these expert connections which SDV's are intended to sever.
Not quite sure what to make of that statement? When an SDV is standardized by ISO, the expectation is that the connections between data and processes would be fully understood, and implementations consistent across the board.
Sadly, ODF is ISO approved, but doesn't come close to meeting these expectations. ODF interop might as well be ZERO. And the only way to fix it is to go into the presentation layer of ODF, strip out all the application specific bindings, and fully specifiy the ssemantics of layout.

XML expert, consultant and Microsoft MVP Don Demsak argues that both technologies share a fundamental flaw-they're not really striving to be standards at all.
"I think this whole OOXML versus ODF thing is a non-issue. Both formats are just serialization formats for the object models they're associated with, and are not designed as impartial, interoperable formats," Demsak writes in an e-mail.
Gary Edwards, president of the OpenDocument Foundation, which drives ODF development, believes codified document standards should not carry forward old flaws and application nuances.
"The world is not a clean slate, but it's going to somehow make that transition of existing documents, applications and processes to XML," he says in an e-mail.
"To us, that is an open XML file format consistent with the continuing work of the W3C that also meets the following criteria: open, unencumbered, universally interoperable, totally application-platform-vendor independent, with an acceptable citizen-driven governance," Edwards writes.

There is nothing open about MOOXML, and it should have never made it to consideration as an international standard.
But one has to ask, what is up with Sun? The John Bosak comment is just as much cause for concern as the fact that the nations of the world would dare consider OOXML as an international standard. All i can say is that we've been had. Sun and Microsoft have worked us royally, and only now, at the last moment, does the fog of confusion clear and we can see it all.

It's beyond important that perople understand the nature of the MSOffice lock-in barriers that ODF and PDF must overcome. If our only problem was that of converting legacy MSOffice binary docuemnts to ODF or PDF, we would have broken the monopolist grip years ago.
What people have to realize is that it is the MSOffice bound workgroup-workflow business process barrier that is near impossible to overcome!
Let's go one step further and admit that Micrsoft's plugin approach for installing OOXML and XML-PDF in MSOffice is the only way to "realistically" overcome this business process barrier.
Which means there is an interesting corrollary for ODF. Only the internal ODF-PDF plugins for MSOffice will be able to similarly overcome the business process barrier. Rip out and replace approaches are too costly and disruptive. So much so that even in governments like Massachusetts, where they had mandated ODF, it has proved impossible to implement ODF.
One way of looking at this problem is to take the OASIS ODF big vendor blinders off and see clearly that the way Microsoft deals with the problem of converting existing documents and bound business processes to XML, is to provide their own OOXML :: XML-PDF plugin for existing MSOffice desktops.
Note well one other phenomenon confirming the efficacy of the plugin approach. The Microsoft - Novell deal resulted in a OOXML plugin for OpenOffice! Subsequent Micrsoft deals feature this highly controlled and directed version of "interoperability" through agreements with prominent LiNUX vendors tha tthey distribute the Novell OpenOffice version with the OOXML plugin set as the default file format!
The same ODF vendors who opposed an internal ODF Plugin for MSOffice, are now shipping an OpenOffice with the OOXML plugin set as default.
(With Sun is not far behind - from the document, "Interoperability Wars", we have this collection of gems:
.... Yes, Sun will, but not as a return favor. Sun is cooperating with
Novell on the OfficeOpenXML Translator plugin for OpenOffice, even
though they virulently opposed Novell's much needed "Interoperability
Enhancement" proposals on the OpenDocument Technical Committee. Sun
will focus on a high fidelity import of OfficeOpenXML into OpenOffice,
but most likely will put little if any effort into export. The old
one-way street trap that helped Microsoft to fame and fortune. Novell
is working on OOo export to OOXML.

The OpenDocument Foundation's da Vinci pllugin for MSOffice is simply a clone of the Microsoft OOXML plugin (which is also called the XML Compatibility Kit :).
Interstingly, when Massachusetts was evaluating da Vinci, one of the priorities they asked for was that we focus on the PDF-ODF digital signature package. This is a design concept we presented to Massachusetts to include in da Vinci a PDF conversion. But not just any PDF conversion. What we proposed was to embed the ODF markup with the PDF file, implementing a digital signature to protect the ODF markup.
The PDF-ODF file could be opened in any Acrobat reader. This is a "static" view of the content. Or, if one had access to the digitally signed ODF markup, one could "interactively" access the contents using an ODF application. Including any da Vinci converted MSOffice workgroup-workflow bound desktop.
Now it appears that Microsoft is about to do the same thing with their OOXML :: XML-PDF plugin. Very cool, and much needed. But not something that can't also be done in ODF.
One area in his commentary where Andy makes a grave mistake is where he states:
#1This
seems to me to be a turning point for the creation of global
standards. Microsoft was invited to be part of the original ODF
Technical Committee in OASIS, and chose to stand aside. That committee
tried to do its best to make the standard work well with Office, but
was naturally limited in that endeavor by Microsoft's unwillingness to
cooperate. This, of course, made it easier for Microsoft to later claim
a need for OOXML to be adopted as a standard, in order to "better serve
its customers." The refusal by an incumbent to participate in an open
standards process is certainly its right, but it is hardly conduct that
should be rewarded by a global standards body charged with watching out
for the best interests of all.
This statement is absolutely true of the original OASIS ODF TC (Technical Committee) that first met in December of 2002. In fact, it was true throughout the first fifteen months of ODF TC activity. Everyone on that first TC group supported full interoperability with Microsoft applications and documents, except for one company - Sun.
There are three areas of "interoperability" that Sun opposed then, and continues to oppose today. The only difference being that after their 2004 deal with Microsoft, Sun has been uncompromisingly determined to block the interoperability the marketplace demands.
Prior to the 2004 deal, there is much evidence of interop flexibility that made it's way past Sun and into the ODF specification. It's not without good reason that the ODF 1.0 Conformance Section is also called the "universal generic".
The problem is that these interop holes in the ODF spec are "optional", and subsequently not supported or implemented by Sun's OpenOffice/StarOffice code base. In fact, almost anywhere you find "optional" implementation choices in ODF, most likely your starring at an interoperability break point.
Since the 2004 deal, the binding of ODF to Sun's OpenOffice/StarOffice feature set has hardened. So much so that after the failure of ODF in Massachusetts, CIO's across the nation started refering to ODF as having zero interop; a nice XML format that is impossible to implement in real world situations. A real world filled with situations dominated by MSOffice bound workgroup-workflow business processes.
Today the OASIS ODF TC is completly 180 degrees opposite the one that met in December of 2002.
There are three categories that define the "interoperability" problem:The CIO's who must deal with 15 years of MSOffice line of business development, need XML document solutions that can meet all three of the above interope criteria. The over riding problem for CIO's is that of migrating their documents and business processes to XML. The only question is, "Which XML, ODF or OOXML?
- Compatibility with existing file formats and documents
- Interoperability at the Application layer
- Convergence - the portability of an XML document across desktop, server, device and web information systems
So far ODF has been a no show. The only thing big ODF vendors have to offer is rip out and replace desktop alternatives to MSOffice. These are too costly and disruptive in terms of the bound business proceses to ever be considered, as evidenced by a year long ODF Pilot Study conducted by the Commonwealth of Massachusetts. A study that resulted in the Massachusetts Request for Information about the possibility of an ODF plugin for MSOffice. The Pilot Study was such a disaster for ODF that it was burried forever, never to see the light of day.
That leaves the entire future of ODF with the internal ODF plugins for MSOffice. An approach the big ODF do not support in either the marketplace, or, perhaps most importantly, at the level of the OASIS ODF TC - where "compatibility, interoperability and convergence" capabilites either go into the spec, or not.
Since 2004, it's been 100% NOT!
The proof of this can be seen in any number of OASIS ODF TC proposals and discussions. The most recent examples being threads having to deal with List Enhancement Proposals and Metadata XML/RDF.
The current membership of the OASIS ODF TC is clearly and unequivocably on record as opposed to the interoperability the marketplace is screaming for. The issues of "compatibility, interoperability, and convergence", as described above have been called by current TC members: "out of bounds", "out of scope", "not our problem", "let the converters and transformers deal with it", and "talk to Microsoft".
If Micrsoft were to join the OASIS ODF TC today, seeking to adapt ODF to meet the legacy document-MSOffice features-line of business integration needs of their monopoly base, the TC would have to deal with the exact same issues as they have summarily rejected with current compatibility-interoeprability-convergence disussions!
There is no possible way anyone can claim that today's OASIS ODF TC would welcome Microsoft and make accomodating changes to the specification! No way! And the proof of this hostility can be seen in the actual disussions and rejections of Micrsoft specific interoperability proposals.
Andy is out of touch and clearly drinking the kool-aid.

"ECMA 376" is a set of file formats subject to ECMA and now to ISO.
"Office 2007" is a set of file formats which extend "ECMA 376" file formats.
Office 2007 file formats are undocumented per se. ECMA 376 are.
ECMA 376 file formats are documented but only at a syntactic level. To realize the true meaning of every single attribute is to realize that the documentation is more like 600,000 pages, not 6,000. Of particular difficulty is to keep some kind of control over the virtually infinite combinations of such attributes.
Quick analysis of the underlying schemas reveals that simple concepts such as text formatting is expressed in no less than 6 different and incompatible ways. This leads to thinking that the file formats were only designed to comply with existing legacy formats that themselves are the result of 15 years of inside/outside library aggregation (some of the libraries were bought from non-Microsoft vendors). In fact, the truth is, ask any reverse engineer third-party who worked with legacy formats, they'll tell you Microsoft essentially added angle brackets around the binary serialization in legacy formats. This makes for a very cool XML-based file format, not an international standard.
