Harmonization Wars : Is it jetlag? | Brian Jones: Open XML- Open Document Formats - 0 views

  • if you actually read the Ecma response, you'll see that TC45's position is actually quite the opposite. Harmonization is not as simple as just adding a few tags here and there. It's going to be a lot of hard work, and the German Standard Body (DIN) is already working on the first step, which is to identify the differences. This isn't something to take lightly. Here is Ecma's full response to this issue (emphasis added): There are currently several XML-based document formats in use, each designed to address a different set of goals or requirements. These include ISO/IEC IS 26300 (ODF), China's UOF, and ECMA-376 (DIS 29500 – Open XML). All these formats have numerous implementations in multiple tools and multiple platforms (Linux, Windows, Mac OS, hand-held devices). The Ecma Response Document from the Fast Track 30-Day contradiction phase for DIS29500 addressed the question of harmonization by explaining the differences between the ODF and Open XML formats as follows:

    Brian Jones responds to Rob Weir's very strange demand that he be put in charge of any harmonization effort involving ODF and OOXML.
    In his response, Brian points to the Ecma official statement in support of harmonization provided in February of 2007. The harmonization response was directed at ISO National Body members objecting to the proposed fast tracking of OOXML.
    In late February -early March of 2007, the EU held an "interoeprability Workshop" in Berlin, Germany.The session was attended by IBM, Sun and Microsoft, as well as Ecma and OASIS.
    The EU took a very hard line position on "harmonization", embracing a position put forward by the French ISO NB group known as AFNOR. The WorkShop was followed by the EU establishment of DIN Workgroup NIA-01-34, headed by the Fraunhoffer Fokus Institute.
    The DIN WG sent out invites to all the major players, with Microsoft and Novell accepting the invitation to particpate in the harmonizatioon effort. IBM and Sun refused the invitation.
    Recently DIN invited the OASIS ODF Technical Committee to join the harmonization effort. The OASIS TC responded by asking Novell developer (and DIN participant) Florian Reuter to act as liaison to DIN. ODF grand puba Rob Weir himself put forward this request.
    Here's the thread: http://www.oasis-open.org/archives/office/200801/msg00040.html
    Now it looks like the grand puba is backtracking! Rob Weir wants to put himself in charge of harmonization. And we all know where that would lead.
    Harmonization will be difficult. It might even be impossible. As indicated by the Ecma statement Brian copiies in his post.
    The dynamics of harmonization are fairly simple to understand; you can't harmonize two application specific formats without also harmonizing the applications. This problem is further complicated by the fact that the presentation layers (styles) of both ODF

The ODF Alliance puckers up and gets smacked with the great CSS question - Where is it?... - 0 views

  • Harmonisation It is interesting that the ODF Alliance quotes Tim Bray that the world doesn’t need another way to express basic typesetting features. If it is so important, why didn’t ODF just adopt W3C CSS or ISO DSSSL conventions? Why did they adopt the odd automatic styles mechanism which no other standard uses? Now I think the ODF formating conventions are fine, and automatic styles are a good idea. But there is more than one way to make an omlette, and a good solution space is good for users. My perspective is that harmonisation (which will take multiple forms: modularity, pluralism, base sets, extensions, mappings, round-trippability, feature-matching, convergence of component vocabularies, etc, not just the simplistic common use of a common syntax) will be best achieved by continued user pressure, both on MS and the ODF side, within a forum where neither side can stymie the legitimate needs of other.

    MS-OOXML supporter Rick Jellife discusses the ODF Alliance response to Ecma's proposed disposition of ISO NB comments on OOXML. The Allaince response has recieved quite a bit of ink, wtih waves of ODF jihadists pointing to it as incontroverible evidence that they are right. Rick provides a lengthy response, most of which presents the ODF jihadis with some difficult issues they must now explain. More importantly though, RJ uncovers one of the more glaring examples proving that ODF is application specific to the core, and bound to OpenOffice. He points out that OpenOffice ODF could have chosen the W3C's highly portable and infinitely interoeprable CSS as the ODF presentation layer. This would have been a great reuse of existing standards. But that's not what happened! Instead of the widely used CSS, OpenOffice chose an incredibly application specific presentation model with the unique innovation of "automatic-styles". And with this choice came years of problematic zero interop as application after application try to exchange ODF documents with little success. Take for example KDE-KOffice. They've been a member of the OASIS ODF TC for near five years now, almost since the beginning. Yet it's impossible to exchange all but the most basic of documents with any of the OpenOffice derivaties (OpenOffice, StarOffice, Novell Office, and Lotus Symphony - OOo 1.1.4). If after five years of active particpation and cooperative efforts, KOffice is unable to exchange ODF docuemnts with OpenOffice, how is it that somehow Microsoft Office would be able to implement ODF without similar zero interop results? Isn't the purpose of standardized formats that end users of different applications could effectively exchange documents? The truth is that both ODF and OOXML are application specific formats. And you can't harmonize, merge, map, or translate between two application specific formats without also having harmonized the appli

  • Most (quality) specifications provide clear instructions using those magic words SHALL, SHALL NOT, and MAY where those words have a defined meaning for an implementor. Paragraphs are clearly identified as either normative or informative. That way an implementor knows what they must and may implement to claim conformance against a specification. This approach has been well established over time as a sensible way for spec writers and implementors to work That is the way quality specifications are written. For example, ISO/IEC's JTC 1 Directives (link to PDF) requires that international standards designed for interoperability "specify clearly and unambiguously the conformity requirements that are essential to achieve the interoperability." With that clarity, conformance is testable and can provide confidence of interoperability. A suite of tests may be developed and applied to an implementation to determine which tests pass, which fail, and hence arrive at an objective pronouncement on conformance of an implementation against the entirety of the specification.
  • In a quality specification, it should be feasible to select a normative paragraph, identify a conformance test for it, and make a clear statement that this test proves that an implementation meets (or fails to meet) that requirement. Call it a test plan: define the tests (test specification), define the expected set of results, and define what constitutes a "pass" of each test that establishes conformance. The plan then provides the matrix of test spec against requirement. Simple.

  • Rob Weir of IBM chaired (apology for the misuse of that last word) the formation list and then simply announced what the charter would be rather than seeking consensus among the list participants. As part of this process before that charter was produced and while I still naively believed that consensus was a goal, I sat down with ODF 1.1 and did a paragraph-by-paragraph review for testability. The numbers were quite revealing. I completely reviewed only the first four major sections and found very few clear requirements. The majority were mere statements with no normative language used to identify what was required or optional. Implementors would have to make their own interpretation.
  • It's ironic that the chair viewed as good news the fact that there were far fewer testable paragraphs than he had predicted. But his prediction of 10,000 test cases is probably far closer to how many testable paragraphs there should be; my counts were actually bad news.
  • All of the above leads to the interesting question of just how the chair expects to accomplish much that is useful in regard to ODF conformance testing before the specification is amended to tighten up the language and add clear requirements. The syntax conformity is already handled by validation against the schema, but the semantics are woefully under-specified.
  • Summary: ODF 1.1 isn't verifiable as a specification. From a fairly cursory review of the latest draft, ODF 1.2 will follow the same path. With OASIS now being more demanding regarding conformance requirements on every specification and with ISO/IEC taking a closer interest in liaison with the ODF TC, I find it hard to see how the ODF TC co-chairs can maintain this view toward verification.

Slamming the door shut on MS OOXML - 0 views

  • So your goal is a networked world where metadata is routinely trashed by apps developed by those who are too dumb or otherwise disabled to preserve metadata and only the big boys get to do interoperability, right? So if I send you a document for your editing, I can't count on getting it back with xml:id attributes intact. No thanks, Patrick. That sounds way too much like how things have worked ever since office productivity software first came on the market. In your world, interoperability belongs only to those who can map features 1:1 with the most featureful apps. And that is precisely why OpenDocument never should have been approved as a standard. Your kind of interoperability makes ODF a de facto Sun Microsystems standard wearing the clothing of a de jure standard. Why not just standardize the whole world on Microsoft apps and be done with it? Are two monopolies maintained by an interoperability barrier between them better than one? Fortunately, we don't have to debate the issue because the Directives resolve the issue. You lose under the rules of the game.

    Marbux on metadata and the language of universal interoperability: Few people are aware of the raging debate that has pushed ODF to the edge. The OASIS ODF TC is split between those who support Universal Interoperability, and those who insist on continuing with limited ODF interoperability.

    ODF (OpenDocument), formally known as Open Office XML, began it's standards life in the fall of 2002 when Sun submitted the OpenOffice file format to OASIS for consideration as a office suite XML fiel format standard. The work on ODF did not start off as a clean slate in that there were near 600 pages of application specific specification from day one of the standards work. The forces of universal interop have sought for years to separate ODF from the application specific features and implementation model of OpenOffice that began with those early specification volumes, and continues through the undue influence Sun continues to have over the ODF specification work.

    Many mistakenly believed that submission of ODF to ISO and subsequent approval as an international standard would provide an effective separation, putting ODF on the track of a truly universal file format.

    Marbux is one of those Universal Interop soldiers who has dug in his heels, cried to the heavens that enough is enough, and demanded the necessary changes to ODF interoperability language.

    This post he recently submitted to the OASIS ODF Metadata SC is a devastating rebuttal to the arguments of those who support the status quo of limited interoperability.

    In prior posts, marbux argues that ISO directives demand without compromise universal interoperability. This demand is also shared by the World Trade Organization directives regarding international trade laws and agreements. Here he brings those arguments together with the technical issues for achieving universal interop.

    It's a devastating argument.

Independent study advises IT planners to go OOXML | All about Microsoft | ZDNet.com - 0 views

  • “ODF represents laudable design and standards work. It’s a clean and useful design, but it’s appropriate mostly for relatively unusual scenarios in which full Microsoft Office file format fidelity isn’t a requirement. Overall, ODF addresses only a subset of what most organizations do with productivity applications today.” The report continues: “ODF is insufficient for complex real-world enterprise requirements, and it is indirectly controlled by Sun Microsystems, despite also being an ISO standard. It’s possible that IBM, Novell, and other vendors may be able to put ODF on a more customer-oriented trajectory in the future and more completely integrate it with the W3C content model, but for now ODF should be seen as more of an anti-Microsoft political statement than an objective technology selection.”
    • Gary Edwards
       
      Mary Jo takes on the recently released Burton Group Report comparing OOXML and ODF. Peter O'Kelly, one of the Burton Group authors, once famously said, "ODF is a great format if you live in an alternative universe where MSOffice doesn't exist!" This observation speaks to the core problem facing ODF and those who seek to implement the ODF standard: ODF was not designed for the conversion of MSOffice documents. Nor was ODF designed to work with MSOffice applications. Another way of saying this is to state that ODF was not designed to be interoperable with MSOffice documents, applications and bound processes. The truth is that ODF was designed for OpenOffice/StarOffice. It is an application specific format. Both OOXML and ODF do a good job of separating content from presentation (style). The problem is that the presentation - layout layers of both ODF and OOXML remains bound to specific applications producing it. While the content layers are entirely portable and can be exchanged without information loss, the presentation layers can not. Microsoft makes no bones about the application specific design and purpose of OOXML. It's stated right in the Ecma 376 charter that OOXML was designed to be compatible with MSOffice and the billions of binary documents in MSOffice specific binary formats. The situation however is much more confusing with ODF. ODF is often promoted as being application, platform and vendor independent. After five years of development though, the OASIS ODF TC has been unable to strip ODF of it's OpenOffice/StarOffice specific aspects. ODF 1.0 - ISO 26300 had three areas that were under specified; meaning these areas were described in syntax only, and lacked the full semantics demanded by interoperable implementations. Only OpenOffice and StarOffice code base applications are able to exchange documents with an acceptable fidelity. The three under specified areas of ODF are: Lists (numbered), F

XML.com: Standard Data Vocabularies Unquestionably Harmful - 0 views

  • At the onset of XML four long years ago, I commenced a jeremiad against Standard Data Vocabularies (SDVs), to little effect. Almost immediately after the light bulb moment -- you mean, I can get all the cool benefits of web in HTML and create my own tags? I can call the price of my crullers <PricePerCruller>, right beside beside <PricePerDonutHole> in my menu? -- new users realized the problem: a browser knows how to display a heading marked as <h1> bigger and more prominently than a lowlier <h3>. Yet there are no standard display expectations or semantics for the XML tags which users themselves create. 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.
    • Gary Edwards
       
      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 presentation layer of each is woefully underspecified!
      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!
  • There have also emerged a few "horizontal" data vocabularies, intended for expressing business communication in more general terms. One of these is the eXtensible Business Reporting Language (XBRL), about which more below. Most recently, governments and governmental organizations have begun to suggest and eventually mandate particular SDVs for required filings, a development which expands what troubles me about these vocabularies by an order of magnitude.

      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.
    • Gary Edwards
       
      "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.
    • Gary Edwards
       
      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.
    • Gary Edwards
       
      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.
  • In short, 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 precisely these expert connections which standard data vocabularies are intended to sever.

An Antic Disposition: Cracks in the Foundation - IBM takes over ODF - 0 views

  • You must admire their tenacity. Gary Edwards and the pseudonymous "Marbux". The mythology of Silicon Valley is filled with stories of two guys and a garage founding great enterprises. And here we have two guys, and through blogs, interviews, and constant attendance at conferences, they have become some of the most-heard voices on ODF. Maybe it is partly due to the power of the name? The "OpenDocument Foundation" sounds so official. Although it has no official role in the ODF standard, this name opens doors. The ODF Alliance , the ODF Fellowship, the OASIS ODF TC, ODF Adoption TC (and many other groups without "ODF" in their name) have done far more to promote and improve ODF, yet the OpenDocument Foundation, Inc. seems to score the panel invites. Not bad for two guys without a garage.
  •  
    An eMail went out today, October 24th, 2007, nominating IBM's Rob "Show me your garage!" Weir to be the new Co Chairman of OASIS ODF TC.  So it's looks like it's true; IBM is moving to take over ODF and OpenOffice.

    Not that that's bad.  In the long run this is perhaps the best thing that ever happened to ODF and OpenOffice.  There is no way IBM's Lotus Notes business plan for ODF-OOo could be any worse than Sun's plan has turned out to be.

    So, South Africa was watching closely the failed effort in Massachusetts to implement ODF?  And now they are determined to make it work? Good thing they left themselves a "pragmatic" out; "there are standards which we are obliged to adopt for pragmatic reasons which do not necessarily fully conform to being open in all respects."

    Massachusetts spent a full year on an ODF implementation Pilot Study only to come to the inescapable conclusion that they couldn't implement ODF without a high fidelity "round trip" capable ODF plug-in for MSOffice.  In May of 2006, Pilot Study in hand, Massachusetts issued their now infamous RFi, "the Request for Information" concerning the feasibility of an ODF plug-in clone of the MS-OOXML Compatibility Pack plug-in for MSOffice applications. At the time there was much gnashing of teeth and grinding of knuckles in the ODf Community, but the facts were clear. The lead dog hauling the ODf legislative mandate sleigh could not make it without ODf interoperability with MSOffice. Meaning, the rip out and replace of MSOffice was no longer an option. For Massachusetts to successfully implement ODf, there had to be a high level of ODf compatibility with existing MS documents, and ODf application interoperability with existing MS applications. Although ODf was not designed to meet these requirements, the challenge could not have been any more clear. Changes in ODf would have to be made. So what happened?

ODF and OOXML - The Final Act - 0 views

  • The format war between Microsoft’s Open Office XML (OOXML) and the open source OpenDocument Format (ODF) has flared up again, right before the looming second OOXML ISO vote in March.
  • “ISO has a policy that, wherever possible, there should only be one standard to maximise interoperability and functionality. We have an international standard for digital documentation, ODF,” IBM’s local government programs executive Kaaren Koomen told AustralianIT.
  • ODF has garnered some criticism for being a touch limited in scope, however, one of its strengths is that it has already been accepted as a worldwide ISO standard. Microsoft’s format on the other hand, has been criticised for being partially proprietary, and even a sly attempt by the software giant to hedge its bets and get in on open standards while keeping as many customers locked into its solutions as possible.
    • Gary Edwards
       
      A "touch limited in scope"? Youv'e got to be kidding. ODF was not defined to be compatible with the billions of MSOffice binary (BIN) documents. Nor was it designed to further interoperability with MSOffice.
      Given that there are over 550 million MSOffice desktops, representing upwards of 95% of all desktop productivity environments, this discrepancy of design would seem to be a bit more than a touch limited in scope!
      Many would claim that this limitation was due to to factors: first that Microsoft refused to join the OASIS ODF TC, which would have resulted in an expanded ODF designed to meet the interoperability needs of the great herd of 550 million users; and second, that Microsoft refused to release the secret binary blueprints.
      Since it turns out that both IBM and Sun have had access to the secret binary blueprints since early 2006, and in the two years since have done nothing to imptove ODF interop and conversion fidelity, this second claim doesn't seem to hold much water.
      The first claim that Microsoft didn't participate in the OASIS ODF process is a bit more interesting. If you go back to the first OASIS ODF Technical Committee meeting, December 16th, 2002, you'll find that there was a proposal to ammend the proposed charter to include the statemnt that ODF (then known as Open Office XML) be compatible with existing file formats, including those of MSOffice. The "MSOffice" reference was of course not included because ODF sought to be application, platform and vendor independent. But make no mistake, the discussion that day in 2002 was about compatibility and the conversion of the legacy BIN's into ODF.
      The proposal to ammend the charter was tabled. Sun objected, claiming that people would interpret the statement as a direct reference to the BIN's, clouding the charter's purpose of application, platform and vendor independence. They proposed that the charter ammendment b

      Will harmonization work? I don't think so. The problem is that the DIN group is trying to harmonize two application specific formats. OpenOffice has one way of implementing basic document structures, and MSOffice another. These differences are directly reflected in the related formats, ODF and OOXML. Any attempts to harmonize ODF and OOXML will require that the applications, OpenOffice and MSOffice, be harmonized! There is no other way of doing this unless the harmonized spec has two different methods for implementing basic structures like lists, tables, fields, sections and page dynamics. Not to mention the problems of feature disparities. If the harmonized spec has two different implementation models for basic structures, interoeprability will suffer enormously. And interoperability is after all the prupose of the standardization effort. That brings us to a difficult compromise. Should OpenOffice compromise it's "innovative" features and methods in favor of greater interoperability with MSOffice and billions of binary documents? Let me see, 100 million OpenOffice installs vs. 550 MSOffice installs bound to workgroup-workflow business processes - many of which are critical to day to day business operations? Sun and IBM have provided the anser to this question. They are not about to compromise on OpenOffice innovation! They believe that since their applications are free, the cost of ODF mandated "rip out and replace" is adequately offset. Events in Massachusetts prove otherwise! On July 2nd, 2007, Sun delivered to Massachusetts the final version of their ODF plug-in for MSOffice. That night, after reviewing and testing the 135 critical documents, Massachusetts made a major change to their ETRM web site. They ammended the ETRM to fully recognize OOXML as an acceptable format standard going forward. The Massachusetts decision to overturn th

      The Burton Group did not recommend that ISO recognize OOXML as a standard! They pointed out that the marketplace is going to implement OOXML by default simply because it's impossible to implement ODF in situations where MSOffice dominates. ISO should not go down the slippery slope of recognizing application-platform-vendor specific standards. They already made that mistake with ODF, and recognizing OOXML is hardly the fix. What ISO should be doign is demanding that ODF fully conform with ISO Interoeprability Requirements, as identified in the May 2006 directive! Forget OOXML. Clean up ODF first.
  •  
    Correcto mundo! There should be only one standard to maximise interoeprability and functionality. But ODF is application specific to the way OpenOffice works. It was not designed from a clean slate. Nor was the original 2002 OpenOffice XML spec designed as an open source effort! Check the OOo source code if you doubt this claim. The ONLY contributors to Open Office XML were Sun employees! What the world needs is in fact a format standard designed to maximise interoperability and functionality. This requires a total application-platofrm-vendor independence that neither ODF or OOXML can claim. The only format that meets these requirements is the W3C's family of HTML-XML formats. These include advancing Compound Docuemnt Framework format components such as (X)HTML-5, CSS-3, XForms, SVG and SMiL.. The W3C's CDF does in fact meet the markeplace needs of a universal format that is open, unencumbered and totally application, platform and vendor independent. The only trick left for CDF is proving that legacy desktop applications can actually implement conversions from existing in-memory-binary-representations to CDF without loss of information.

  • What’s distinctive about the goals of OOXML? Primarily, to have full fidelity with pre-existing binary documents created in Microsoft Office. “What people want is to make sure that their billions of important documents can be saved in a format where they don’t lose any information. As a design goal, we said that those formats have to represent all the information that enables high-fidelity migration from the binary formats”, says Paoli. He mentions work with institutions including the British Library and the US Library of Congress, concerned to preserve the information in their electronic archive. I asked Paoli if such users could get equally good fidelity by converting their documents to ODF. “Absolutely not,” he says. “I am very clear on that. Those two formats are done for different reasons.” What can go wrong? Paoli gives as an example the myriad ways borders can be drawn round tables in Microsoft Office and all its legacy versions. “There are 100 ways to draw the lines around a table,” he says. “The Open XML format has them all, but ODF which has not been designed for backward compatibility, does not have them. It’s really the tip of the iceberg. So if someone translates a binary document with a table to ODF, you will lose the framing details. That is just a very small example.”
  • “Open Document Format and Office Open XML have very different goals”, says Paoli, responding to the claim that the world needs only one standard XML format for office documents. “Both of them are formats for documents … both are good.”

      The door should have been slammed shut on OOXML near five years ago when, on December 14th, 2006, at the very first OASIS ODF TC meeting, Stellent's Phil Boutros proposed that the charter include, "compatibility with existing file formats and interoperability with existing applications" as a priority objective.
  • Another benefit Paoli claims for OOXML is performance. “A lot of things are designed differently because we believe it will work faster. The spreadsheet format has been designed for very big spreadsheets because we know our users, especially in the finance industry, use very large spreadsheets.
    • Gary Edwards
       
      Wrong. The da Vinci plug-in prototype we demonstrated to Massachusetts on June 19th, 2006 proved that there is little or no difference in spreadsheet performance between a OOXML file, and an ODF file.

      In fact, ODF version of the extremely large test file beat the OOXML load by 12 seconds.

      Where the performance difference comes in is at the application level. MS Excel can load a OOXML version of a large spreadsheet faster than OpenOffice can load an ODF version of that same spreadsheet.

      If you eliminate the application differential, and load the OOXML file and the ODF version of that same spreadsheet into a plug-in enabled Excel, the performance differences are negligible.

      The reason for this is that the OOXML plug-in for Excel has a conversion overhead identical to the da Vinci plug-in for Excel. It has nothing to do with the file format, and everythign to do with the application.

The donnybrook resulted i a total breakdown of the ODF consensus process. But, it ensured that never again would anyone be stupid enough to challenge Sun's authority and control of the OASIS ODF TC.

      Sun made it clear that they would viciously oppose any other efforts to establish interoperability with existing Microsoft documents, applications, processes effort.

      Point taken.

  • the idea that Sun is preparing a reference implementation of OOXML is laughable.
    • Gary Edwards
       
      Sorry Tim. It's true. Sun and Novell are working together to develop native OOXML file support in OpenOffice. You can find this clearly stated in the Gullfoss Planet OpenOffice blogs.

      The funny thing is that Sun will have to implement and support the November 20th iX enhancements submitted by Novell!! (Or, the interoperability frameworks also submitted by Novell in February of 2007). There is simply no other way for OpenOffice to implement OOXML with the needed fidelity.

      ~ge~
  • One of new scenarios enabled by the “custom xml parts” (again, if you read their blogs, you must have heard of this stuff) is the ability to bind xml sources and a control+layout so that it enables the equivalent of data queries (we’ve had in Excel for many years already), just with a source which is part of the package, contrary to the typical external data source connection. Well this stuff, besides the declaration (which includes, big surprise, GUIDs and stuff like that) requires the actual Office 2007 run-time to work. So whenever MS says this stuff is interoperable, they cannot mean you can take this stuff away in another application. Because you can’t. This binding is more or less the same than the embedding of VBA macros. It’s all application-specific, and only Microsoft’s own suite knows how to instantiate this stuff.
    • Gary Edwards
       
      Stephan whacks this one out of the park! Smart Documents will replace VBa scripts, macros and OLE functionality going forward. It's also the data binding - workflow and metadata model of the future. And it's all proprietary!

      It's the combination of OOXML plus the MSOffice- Vista Stack specific Smart Documents that will lock end users into the Vista Stack for years to come.

      Watch out Google!

      ~ge~
  • Has Microsoft published the .doc spec publicly? Then why should ODF worry about the past? It’s not ODF’s concern to worry about Microsoft’s past formats. (Understand that the .doc format alone changed six times in the last eight versions of Office!) That’s Microsoft’s legacy problem, not ODF’s.
    • Gary Edwards
       
      There really is no need to access the secret binary blueprints. The ACME 376 plug-in demonstration proves this conclusively. The only thing the ACME 376 demo lacks is that we didn't throw the switch on the magic key to release all VBa scripts, macros and OLE bindings to ACME. But that can be done if someone is serious about converting the whole shebang of documents, applications and processes.

      The real problem is that although ACME 376 proves we can hit the high fidelity required, it is impossible to effectively capture that fidelity in ODF without the iX interoperability enhancements. The world expects ODF interoperability. But as long as Sun opposes iX, we can't pipe from ACME 376 to ODF.

      ~ge~
  • I put it to Paoli that OOXML is hard to implement because of all its legacy support, some of which is currently not well documented. “I don’t believe that at all. It’s actually the opposite,” he says. He make the point that third parties like Corel, which have previously implemented support for binary formats like .doc and .xls, should find it easy to transition to OOXML. “We believe Open XML adoption by vendors like Corel will be very easy because they have already been doing 90% of the work, doing the binary formats. The features are already there.”
    • Gary Edwards
       
      WordPerfect does an excellent import of MSWord .doc documents. But there is no conversion! It's a read only rendering. Once you start editing the document in WP, all kinds of funny things happen, and the perfect fidelity melts away like the wicked witch of west in a bucket full of water.

    Tim Anderson interviews Microsoft's Jean Paoli about MOOXML and ODF.    Jean Paoli of course has the predictable set of answers.  But Tim anderson provides us with some interesting insights and comments of his own.  There is also a gem of a comment from Stephane Rodriquez, the reknown spreadsheet expert.

    The bottom line for Microsoft has not changed.  MOOXML exists because of the need for an XML file format compatible with the legacy of existing MSOffic ebinary documents.  He claims that ODF is not compatible, and offers the "page borders" issue as an example.

    Page borders?  What's that got to do with the ODF file format?   These are application specific, application bound proprietary graphics that can not be ported to any other application - like OpenOffice.  The reason has nothign whatsoever to do with ODF and everything to do with the fact that the page border library is bound to MSOffice and not available to other applications like OpenOffice. 

    So here is an application specific feature tha tJean Paoli claims can not be expressed in ODF, but can in MOOXML.  But when are running the da Vinci ODF plugin in MSWord, there is no problem whatsoever in capturing the page borders in ODF!!!!!!!!!!!!!!!!!!!!!!!!!!!  No problem!!!!!!!!!!

    The problem is opening up that same da Vinci MSWord document in OpenOffice.  That's where the page borders are dropped.  The issue is based entirely on the fact that OpenOffice is unable to render these MSWord specific graphics bound to an MSOffice only library.

    If however we take that same page border loaded da Vinci MSWord document, and send it half way across the world to another MSWord desktop running da Vinci, the da Vinci plugin easily loads the ODF document into MSWord where it is perfectly rendered, page borders and all!!!!!!!!

    Now i will admit that this is one very difficult issue to understand.  If not f

Microsoft Will Support ODF! But Only If ISO Doesn't 'Restrict Choice Among Formats' - 0 views

  • By Marbux posted Jun 19, 2007 - 3:16 PM Asellus sez: "I will not say OOXML is easy to implement, but saying ODF is easier to implement just by looking at the ISO specification is a fallacy." I shouldn't respond to trolls, but I will this time. Asellus is simply wrong. Large hunks of Ecma 376 are simply undocumented. And what's more, absolutely no vendor has a featureful app that writes to that format. Not even Microsoft. There's a myth that Ecma 376 is the same as the Office Open XML used by Microsoft. It is not. I've spend a few hundred hours comparing the Ecma 376 specification (the version of OOXML being considered at ISO) to the information about the undocumented APIs used by MS Office 2007 that recently sprung loose in litigation. See http://www.groklaw.net/p...Rpt_Andrew_Schulman.pdf Each of those APIs *should* have corresponding metadata in the formats, but are not in the Ecma 376 specification.
  •  
    Incredible comment by Marbux!  With one swipe he takes out both Ecma 376 and ODF. 

    Microsoft has written a letter claiming that they will support ODF in MSOffice, but only if ISO approves Ecma 376 as a second office suite XML file format standard.  ODF was approved by ISO nearly a year ago.

    Criticizing Ecma 376 is easy.  It was designed to meet the needs of  a proprietary application, MSOffice, and, to meet the needs of the emerging MS Vista Stack of applications that spans desktop to server to device to web platforms.  It's filled with MS platform dependencies that make it impossibly non interoperable with anything not fully compliant with Microsoft owned API's.

    Criticizing ODF however is another matter entirely.  Marbux points to the extremely poor ODF interoperability record.  If MOOXML (not Ecma 376 - since that is a read only file format) is tied to vendor-application specific MSOffice, then ODF is similarly tied to the many vendor versions of OpenOffice/StarOffice.

    The "many vendor" aspect of OpenOffice is somewhat of a scam.  The interoperability that ODF shares across Novell Office, StarOffice, IBM WorkPlace, Red Office, and NeoOffice is entirely based on the fact that these iterations of OpenOffice are based on a single code base controlled 100% by Sun.  Which is exactly the case with MSOffice.  With this important exception - MOOXML (not Ecma 376) is interoperable across the entire Vista Stack!

    The Vista Stack is comprised of Exchange/SharePoint, MS Live, MS Dynamics, MS SQL Server, MS Internet Server, MS Grove, MS Collaboration Server, and MS Active Directory.   Behind these applications sits a an important foundation of shared assets: MOOXML, Smart Documents, XAML and .NET 3.0.  All of which can be worked into third party, Stack dependent applications through the Visual Studio .NET IDE.

Can a file be ODF and Open XML at the same time? (and HTML? and a Java servlet? and a P... - 0 views

  • The recent bomb in the ODF world from Gary Edward’s claims that Sun successfully blocked the addition of features to ODF that would be needed for full interchange with Office are explosive not only because they demonstrate how ODF was (properly, in my view) developed to cope with the particular features of the participants, not really as a universal format, but also because the prop up Microsoft’s position that Open XML is required because it exposes particular features that ISO ODF is not capable of exposing. Both because ODF is still in progress and because sometimes the features are simply incompatible in the details.
  • Actually, ODF is about to get a new manifest along with the new metadata stuff. Because we base that on RDF, the manifest will also be RDF-based. It gives us the extensibility we want to provide (extension developers, for example, can add extra metadata they may need), without having to worry about breaking compatibility. The primary addition we've made is a mechanism to bind a stable URI to in-document content node ids and files. This is conceptually not all that different than what I see in OPC; it's just that the unique IDs are in fact URIs. Among other things, in the RDF context that allows further statements to be bound to those URIs. Bruce D'Arcus | July 29, 2007 01:02 PM
  •  
    What Bruce doesn't explain in this highlighted clip is that Sun decided to limit the "extra metadata" developer might need to just a handful of elements Sun and IBM needed to use in OpenOffice. The original OpenDocument Foundation metadata proposal was to open up the use of metadata to the extent that metadata could be used for all aspects of presentation (formatting AND layout!).
  •  
    This vendor specific - application specific limiting ended the last hope we had for ODF interoperability and backwards compatibility with the billions of "in-process" MSOffice documents known to be populating business processes the world over. In fact, the problem ODF adoption faces is primarily that of MSOffice bound business processes, reflected in these billions of workgroup-workflow documents.

The End of ODF & OpenXML - Hello ODEF! - 0 views

  •  
    Short slide deck of Barbara Held's February 28th, 2007 EU IDABC presentation. She introduces ODEF, the "Open Document Exchange Format" which is designed to replace both ODF and OpenOfficeXML. ComputerWorld recently ran a story about the end of ODF, as they covered the failure of six "legislative" initiatives designed to mandate ODF as the official file format. While the political treachery surrounding these initiatives is a story in and of itself, the larger story, the one that has world wide reverberations, wasn't mentioned. The larger ODF story is that ODF vendors are losing the political battles because they are unable to provide government CIO's with real world solutions. Here are three quotes from the California discussion that really say it all: "Interoperability isn't just a feature. It's the basic requirement for getting your XML file format and applications considered"..... "The challenge is that of migrating our existing documents and business processes to XML. The question is which XML? OpenDocument or OpenXML?" ....... "Under those conditions, is it even possible to implement OpenDocument?" ....... Bill Welty, CIO California Air Resource Board wondering if there was a way to support California legislative proposal AB-1668. This is hardly the first time the compatibility-interoperability issue has challenged ODf. Massachusetts spent a full year on a pilot study testing the top tier of ODF solutions: OpenOffice, StarOffice, Novell Office and IBM's WorkPlace (prototype). The results were a disaster for ODF. So much so that the 300 page pilot study report and accompanying comments wiki have never seen the light of day. In response to the disastrous pilot study, Massachusetts issued their now infamous RFi; a "request for information" about whether it's possible or not to write an ODF plugin for MSOffice applications. The OpenDocument Foundation responded to the RFi with our da Vinci plugin. The quick descriptio

Is It Game Over? - ODF Advocate Andy UpDegrove is Worried. Very Worried - 0 views

  • This 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.
  •  
    Andy UpDegrove takes on the issue of Microsoft submitting their proprietary "XML alternative to PDF" proposal to Ecma for consideration as an international standard.  MS XML-PDF will compliment ECMA 376 (OOXML - OfficeOpenXML) which is scheduled for ISO vote in September of 2007.  Just a bit over 60 days from today.

    Andy points out some interesting things; such as the "Charter" similarities between MS XML-PDF and MS OOXML submisssions to Ecma:

    MS XML-PDF Scope: The goal of the Technical Committee is to produce a formal standard for office productivity applications within the Ecma International standards process which is fully compatible with the Office Open XML Formats. The aim is to enable the implementation of the Office Open XML Formats by a wide set of tools and platforms in order to foster interoperability across office productivity applications and with line-of-business systems. The Technical Committee will also be responsible for the ongoing maintenance and evolution of the standard.   Programme of Work: Produce a formal standard for an XML-based electronic paper format and XML-based page description language which is consistent with existing implementations of the format called the XML Paper Specification,…[in each case, emphasis added]

    If that sounds familiar, it should, because it echoes the absolute directive of the original OOXML technical committee charter, wh

Open Malaysia: Rick Jelliffe - myths debunked? - 0 views

  • Additionally, ODF was not ratified with SVG, MathML, XLink, Zip and other W3C standards all together at the same time. Instead the prior W3C standards were already well established and approved in their own right and in their own time with the relevant experts of their specific domains vetting it. MSOOXML also incorporates proposed "standards" which failed in the marketplace and now is offered a "backdoor" to standardisation process by piggy backing this nebulous specification. (See VML vs SVG, and MathML vs Microsoft Office MathML) So there is a myth being built that ODF and its constituent parts are just as large as MSOOXML, and therefore MSOOXML is OK. I for one would rather MSOOXML be even larger; to cater for unknown tags like "lineWrapLikeWord6" or a Macro specification. However what troubles me is that the special relationship between Ecma and ISO should be abused with the fast tracking of this large specification.
  •  
    Yoon Kit brings up an interesting point about the ISO consideration of MSOOXML (Ecma 376);  ISO approval of MSOOXML would backdoor a good many MS proprietary technologies that compete directly with W3C XML standards.

    YK gives the example of MS VML, which competes with the W3C SVG standard used by ODF.  He could have also cited that legacy versions of MSOffice (98-2003) make use of VML as the default graphic format, while MSOffice 2003 9with XML plugin) and MSOffice 2007 (by default) implements DrawingML as the replacement for VML. 

    So, would ISO approval of Ecma 376 backdoor VML and DrawingML in as "standards"?  Or MSOffice MathML?   One has to wonder since they are essential to MSOOXML.

Between a rock and a hard place: ODF & CIO's - Where's the Love? - 0 views

  • So I'm disappointed. And not just on behalf of open documents, but on behalf of the CIOs of this country, who are now caught between a rock and a hard place, without a paddle to defend themselves with if they won't to do anything new, innovative and necessary, if a major vendor's ox might be gored in consequence. After the impressive lobbying assault mounted over the past six months against open document format legislation, I expect you won't be hearing of many state IT departments taking the baton back from their legislators.    And who can blame them? If they tried, it wouldn't be likely to be anything as harmless as an open document format that would bite them in the butt.

    Andy Updegrove weighs in on the wave of ODF legislative failures first decribed by Eric Lai and Gregg Keizer compiled the grim data in a story they posted at ComputerWorld last week titled  Microsoft trounces pro-ODF forces in state battles over open document formats.


    Andy believes that it is the failure of state legislators to do their job that accounts for these failures.  He provides three reasons for this being a a failure of legislative duty.  The most interesting of which is claim that legislators should be protecting CIO's from the ravages of aggressve vendors. 


    The sad truth is that state CIO's are not going to put their careers on the line for a file format after what happened in Massachusetts.


    Andy puts it this way, "
      

    And second, in a situation like this, it is a cop out for legislatures to claim that they should defer to their IT departments to make decisions on open formats.  You don't have to have that good a memory to recall why these bills were introduced in the first place: not because state IT departments aren't a good place to make such decisions, but because successive State CIOs in Massachusetts had been so roughly handled in trying to make these very decisions that no state CIO in his or her right mind was likely to volunteer to be the next sacrificial victim.

Wizard of ODF: The Foundation on Interop and the List Proposal Vote Deadline - 0 views

  • Oh, my. Both IBM and Sun voted for the proposal that broke the Foundation's plugin that was going to add full-fidelity native ODF file support to Microsoft Office. So it's sounding to me like at least two of the TC members who voted for the Sun/KOffice proposal didn't check in with the ECIS lawyer before they broke interoperability with Microsoft Office. Do you think Microsoft won't use this evidence in the DG Competition antitrust proceeding, Michael? Let's see, you guys are prosecuting Microsoft for not supporting ODF in Microsoft Office while you block Microsoft Office from supporting ODF. Yeah, I think DG Competition is going to hear about this one from Microsoft. They'll probably hear about what you said about compatibility being a trade off too. Oh, yeah. Microsoft's lawyers are going to love this. Look at the ECIS public statement about interoperability's importance.
  •  
    If ever there was a discussion thread of consequence at the OASIS ODF TC, this is it. This is where the ODF interoperability nightmare burst into the daylight of a showdown vote. The interop issues were clear. OpenDocument TC members voted between interoperability and/or application specific innovation. Application specific innovation trumped interoperability. Again. And wha ta sad day it was. The thing is, the recent ECIS antit trust action against Microsoft comes at the request of IBM and Sun. They allege that Microsoft is violating standards requirements for interoeprability, and has launched a series of corrupt activities to push through a non interoperable standard. They are right. Microsoft is guilty. The problem is that Microsof tcan easily point to Sun and IBM activities at OASIS ODF, and make the same allegation! Using this thread as evidence! Furthermore, this thread is evidence that if Microsoft had tried to implement ODF, their efforts to establish interop would have been met with the same response from IBM and Sun that the OpenDocument Foundation recieved. Or so they could argue. Houston, we have a problem. IBM and Sun could have fixed the ODF interop problems at any time during the past five years. Yet, the world is waiting. Meanwhile, this willfull negligence and lack of desire to address pressing market needs for full interop has served to hold the door open for OOXML. And now these negligent acts llook to be the basis of a Microsoft counter claim. Oh well ..

  • The Case for Harmonization (that IBM will vote against anyway) In my recent post, I discussed the case for harmonization, mainly due to trying to portray a more kindly, conciliatory face in the “standards krieg” that I was enjoying so much. I have been forced to take a different tack, in light of being hung out to dry by my more business-focused IBM comrades and the work that the enemy has done in sprucing up the spec. However, as my closest friends know, for me, there are no half-victories, so you can rest assured that I will not settle for this weak “harmonization” compromise. I set out my (and IBM’s) stall some time ago on this, and as those on the Open Document Foundation know, any attempt at harmonization shall be met with swift and final retribution.  They were ejected from the odf-coven just days after their impudence. I have baited my trap, inviting this “harmonization” in my lair (the OASIS ODF TC) where I can bog them down in a morass of incompetence, bickering and politicking, so no new standard is ever ratified.  I have already been practicing for this, as you can see, by the ODF 1.1 and 1.2 specs.

    This very funny satire builds on some harsh realities. The ODF chickens have come home to roost, and it isn't pretty. Very funny, yes. But not pretty for those who continue to believe that somehow ODF is a standard worthy of their support. The flip side of the coin is that using the same critieria of interoperability, OOXML is worthless. The sad truth is that both ODF and OOXML are applicaiton specific formats that will continue to defy and defeat all efforts at interoperability. Inparticular, it's the presentation layers of ODF and OOXML that remain bound to the layout engines and feature sets of their originating applications. Just as the presentation layers defy interoperability, they will also defeat harmonization. The only way to harmonize two application specific formats is to harmonize the originating applications. And Microsoft, Sun and IBM are not about to do that. The links in this satire are stunning!!! They shout loudly as to how Microsoft is going to respond to the ECIS anti trust allegations. So when you stop laughing, make certain you track down the links and read through the various OASIS ODF archive threads. IBM and Sun had their chance to fix ODF interoperability. Now it may be too late.

Harmonization and Interop: The dizzying dance of ODF, OOXML, and CDF - 0 views

    Will the real universal document format please stand up! Comments on the recent article posted by the Universal Interoperability Council: "Putting Andy Updegrove to bed without his supper". The UIC article is well worth your time. It is extremely well referenced and researched. The arguments put forth counter claims by IBM and OASIS that the W3C's CDF format can not be used to represent desktop productivity environment documents. Not surprisingly, IBM and OASIS argue that the OpenOffice specific ODF is the only alternative to Microsoft Office specific OOXML. The UIC argues that the full range of MSOffice legacy binary documents and emerging XML documents can fully be represented in CDF - something that not even the most ardent of ODF jihadists would claim as an ODF capabilitiy. The truth is that ODF was not designed for the conversion of MSOffice binary and xml documents.
