Microsoft Watch Finally Gets it - It's the Business Applications!- Obla De OBA Da - 0 views

  • To be fair, Microsoft seeks to solve real world problems with respect to helping customers glean more value from their information. But the approach depends on enterprises adopting an end-to-end Microsoft stack—vertically from desktop to server and horizontally across desktop and server products. The development glue is .NET Framework, while the informational glue is OOXML.
    • Gary Edwards
       
      OOXML is the transport - a portable XML document model where the "document" is the interface into content/data/ and media streaming.

      The binding model for OOXML is "Smart Documents", and it is proprietary!

      Smart Documents is how data, streaming media, scripting-routing-workflow intelligence and metadata is added to any document object.

      Think of the ODF binding model using XForms, XML/RDF and RDFA metadata. One could even use Jabber XMP as a binding model, which is how we did the Comcast SOA based Sales and Inventory Management System prototype.

      Interestingly, Smart Documents is based on pre written widgets that can simply be dragged, dropped and bound to any document object. The Infopath applicaiton provides a highly visual means for end users to build intelligent self routing forms. But Visual Studio .NET, which was released with MSOffice 2007 in December of 2006. makes it very easy for application and line of business integration developers to implement very advanced data binding using the Smart Document widgets.

      I would also go as far to say that what separates MSOOXML from Ecma 376 is going to be primarily Smart Documents.

       Yes, there are .NET Framework Libraries and Vista Stack dependencies like XAML that will also provide a proprietary "Vista Stack" only barrier to interoperability, but Smart Documents is a killer.

      One company that will be particularly hurt by Smart Documents is Google. The reason is that the business value of Google Search is based on using advanced and closely held proprietary algorithms to provide metadata structure for unstrucutred documents.

      This was great for a world awash in unstructured documents. By moving the "XML" structuring of documents down to the author - workgroup - workflow application level though, the world will soon enough be awash in highly structured documents that have end user metadata defining document objects and
  • Microsoft seeks to create sales pull along the vertical stack between the desktop and server.
    • Gary Edwards
       
      The vertical stack is actually desktop - server - device - web based.  The idea of a portable XML document is that it must be able to transition across the converged application space of this sweeping stack model.

      Note that ODF is intentionally limited to the desktop by it's OASIS Charter statement.  One of the primary failings of ODF is that it is not able to be fully implemented in this converged space.  OOXML on the other hand was created exactly for this purpose!

      So ODF is limited to the desktop, and remains tightly bound to OpenOffice feature sets.  OOXML differs in that it is tightly bound to the Vista Stack.

      So where is an Open Stack model to turn to?

      Good question, and one that will come to haunt us for years to come.  Because ODF cannot move into the converged space of desktop to server to device to the web information systems connected through portable docuemnt/data transport, it is unfit as a candidate for Universal File Format.

      OOXML is unfi as a UFF becuase it is application - platform and vendor bound.

      For those of us who believe in an open and unencumbered universal file format, it's back to the drawing board.

      XHTML+ (XHTML + CSS3 + RDF) is looking very good.  The challenge is proving that we can build plugins for MSOffice and OpenOffice that can fully implement XHTML+.  Can we conver the billions of binary legacy documents and existing MSOffice bound business processes to XHTML+?

      I think so.  But we can't be sure until the da Vinci proves this conclusively.

      One thign to keep in mind though.  The internal plugins have already shown that it is possible to do multiple file formats.  OOXML, ODF, and XML encoded RTF all have been shown to work, and do so with a level of two way conversion fidelity demanded by existing business processes.

      So why not try it with XHTML+, or ODEF (the eXtended version of ODF en
  • Microsoft's major XML-based format development priority was backward compatibility with its proprietary Office binary file formats.
    • Gary Edwards
       
      This backwards compatibility with the existing binary file formats isn't the big deal Micrsoft makes it out to be.  ODF 1.0 includes a "Conformance Clause", (Section 1.5) that was designed and included in the specification exactly so that the billions of binary legacy documents could be converted into ODF XML.

      The problem with the ODF Conformance Clause is that the leading ODF application, OpenOffice,  does not fully support and implement the Conformance Clause. 

      The only foreign elements supported by OpenOffice are paragraphs and text spans.  Critically important structural document characteristics such as lists, fields, tables, sections and page breaks are not supported!

      This leads to a serious drop in conversion fidelity wherever MS binaries are converted to OpenOffice ODF.

      Note that OpenOffice ODF is very different from MSOffice ODF, as implemented by internal conversion plugins like da Vinci.  KOffice ODF and Googel Docs ODF are all different ODF implementations.  Because there are so many different ways to implement ODF, and still have "conforming" ODF documents, there is much truth to the statement that ODF has zero interoperabiltiy.

      It's also true that OOXML has optional implementation areas.  With ODF we call these "optional" implementation areas "interoperabiltiy break points" because this is exactly where the document exchange  presentation fidelity breaks down, leaving the dominant market ODF applicaiton as the only means of sustaining interoperabiltiy.

      With OOXML, the entire Vista Stack - Win32 dependency layer is "optional".  No doubt, all MSOffice - Exchange/SharePoint Hub applications will implement the full sweep of proprietary dependencies.    This includes the legacy Win32 API dependencies (like VML, EMF, EMF +), and the emerging Vista Stack dependencies that include Smart Documents, XAML, .NET 3.0 Libraries, and DrawingML.

  • Microsoft's backwards compatibility priority means the company made XML-based format decisions that compromise the open objectives of XML. Open Office XML is neither open nor XML.
    • Gary Edwards
       
      True, but a tricky statement given that the proprietary OOXML implementation is "optional".  It is theoretically possible to implement Ecma 376 without the prorpietary dependencies of MSOffice - Exchange/SharePoint Hub - Vista Stack "OOXML".

      In fact, this was first demonstrated by the legendary document processing - plugin architecture expert, Florian Reuter.

      Florian has the unique distinction of being the primary architect for two major plugins: the da Vinci ODF plugin for MSOffice, and, the Novell OOXML Translator plugin for OpenOffice!

      It is the Novell OOXML Translator Plugin for OpenOffice that first demonstrated that Ecma 376 could be cleanly implemented without the MSOffice application-platform-vendor specific dependencies we find in every MSOffice OOXML document.

      So while Joe is technically correct here, that OOXML is neither open nor XML, there is a caveat.  For 95% of all desktops and near 100% of all desktops in a workgroup, Joe's statment holds true.  For all practical concerns, that's enough.  For Microsoft's vaunted marketing spin machine though, they will make it sound as though OOXML is actually open and application-platform-vendor independent.


  • Microsoft got there first to protect Office.
    • Gary Edwards
       
      No. I disagree. Microsoft needs to move to XML structured documents regardless of what others are doing. The binary document model is simply unable to be useful to any desktop- to server- to device- to the web- transport!

      Many wonder what Microsoft's SOA strategy is. Well, it's this: the Vista Stack based on OOXML-Smart Documents-.NET.

      The thing is, Microsoft could not afford to market a SOA solution until all the proprietary solutions of the Vista Stack were in place.

      The Vista Stack looks like this:

      ..... The core :: MSOffice <> OOXML <> IE <> The Exchange/SharePoint Hub

      ..... The services :: E/S HUb <> MS SQL Server <> MS Dynamics <> MS Live <> MS Active Directory Server <> MSOffice RC Front End

      The key to the stack is the OOXML-Smart Documents capture of EXISTING MSOffice bound business processes and documents.

      The trick for Microsoft is to migrate these existing business processes and documents to the E/S Hub where line of business developers can re engineer aging desktop LOB apps.

      The productivity gains that can be had through this migration to the E/S Hub are extraordinary.

      A little over a year ago an E/S Hub verticle market application called "Agent Achieve" came out for the real estate industry. AA competed against a legacy of twenty years of contact management based - MLS data connected desktop shrinkware applications. (MLS-Multiple Listing Service)

      These traditional desktop client/server productivity apps defined the real estate business process as far as it could be said to be "digital".  For the most part, the real estate transaction industry remains a paper driven process. The desktop stuff was only useful for managing clients and lead prospecting. No one could crack the electronic documents - electonic business transaction model.  This will no doubt change with the emer

      Okay, now Joe has the Micrsoft SOA bull by the horns.  Why doesn't he wrestle the monster down?
  • By adapting XML
    • Gary Edwards
       
      The requirements of these E/S Hub systems are XP, XP MSOffice 2003 Professional, Exchange Server with OWL (Outlook on the Web) , SharePoint Server, Active Directory Server, and at least four MS SQL Servers!

      In Arpil of 2006, Microsoft issued a harsh and sudden End-of-Life for all Windows 2000 - MSOffice 2000 systems in the real estate industry (although many industries were similarly impacted). What happened is that on a Friday afternoon, just prior to a big open house weekend, Microsoft issued a security patch for all Exchange systems. Once the patch was installed, end users needed IE 7.0 to connect to the Exchange Server Systems.

      Since there is no IE 7.0 made for Windows 2000, those users relying on E/S Hub applications, which was the entire industry, suddenly found themselves disconnected and near out of business.

      Amazingly, not a single user complained! Rather than getting pissed at Microsoft for the sudden and very disruptive EOL, the real estate users simply ran out to buy new XP-MSOffice 2003 systems. It was all done under the rational that to be competitive, you have to keep up with technology systems.

      Amazing. But it also goes to show how powerfully productive the E/S Hub applications can be. This wouldn't have happened if the E/S Hub applications didn't have a very high productivity value.

      When we visited Massachusetts in June of 2006, to demonstrate and test the da Vinci ODF plugin for MSOffice, we found them purchasing en mass E/S Hubs! These are ODF killers! Yet Microsoft sales people had convinced Massachusetts ITD that Exchange/SahrePoint was a simple to use eMail-calendar-portal system. Not a threat to anyone!

      The truth is that in the E/S Hub ecosystem, OOXML is THE TRANSPORT. ODF is a poor, second class attachment of no use at the application - document processing chain level.

      Even if Massachusetts had mandated ODF, they were only one E/S Hub Court Doc

      What Joe isn't watching is the way the Exchange/SharePoint Server connects to MS SQL Server, Active Directory Server, MS LIve and MS Dynamics.

      Also, Joe does not see the connection between OOXML as the portable XML document/data transport, and the insidiously proprietary Smart Documents metadata - data binding system that totally separates MSOOXML from Ecma 376 OOXML!
  • I'm convinced that Office as a platform is an eventual dead end. But Microsoft is going to lead lots of customers and partners down that platform path.
    • Gary Edwards
       
      Yes, but the new platform for busines process development is that of MSOffice <> Exchange/SharePoint Hub.

      The OOXML-Smart Docs transport replaces the old binary document with OLE and VBA Scripts and Macros functionality.  Which, for the sake of brevity we can call the lead Win32 API dependencies.

      One substantial difference is that OOXML-Smart Docs is Vista Stack ready, while the Win32 API dependencies were desktop bound.

      Another way of looking at this is to see that the old MSOffice platform was great for desktop application integration.  As long as the complete Win32 API was available (Windows + MSOffice + VBA run times), this platform was great for workgroups.  The Line of Business integrated apps were among the most brittle of all client/server efforts, bu they were the best for that generation.

      The Internet offers everyone a new way of integrating data, content and streaming media.  Web applications are capable of loosly coupled serving and consuming of other application services.  Back end systems can serve up data in a number of ways: web services as SOAP, web services as AJAX/REST, or XML data streams as in HTTPXMLRequest or Jabber P2P model.

      On the web services consumption side, it looks like AJAX/REST will be the block buster choice, if the governance and security issues can be managed.

      Into this SOA mash Microsoft will push with a sweeping integrated stack model.  Since the Smart Docs part of the OOXML-Samrt Docs transport equation is totally proprietary, but used throughout the Vista Stack, it will provide Microsoft with an effective customer lockin - OSS lockout point.

      Sounds like the core of a 1992 Windows Desktop Productivity "Compound Document" model.  Applications need to message, exchange and link data.  In 1992, the key technologies embedded in a compound document were DDE, OLE, ODBC, scripts and macros.  Later on, ActiveX and COM was added.  Today the MSOffice desktop productivity environment links into the MS-Live Productivity Cloud or the BPOS - SharePoint private cloud with a raft of WPF-SilverlightX stuff.  Good to see the Open Web fighting back with their own compound document model.

But can money buy love? :: Another Microsoft Sponsored OOXML Study - 0 views

  •  
    Joe Wilson of Microsoft Watch knocks another one out of the park. Why is it that so few in the media get it? Or anyone else for that matter? Matt Assay gets it. But few understand the Vista Stack and the importance of OOXML in the transition of the monopoly base from MSOffice to the Vista Stack. No doubt the arrogance of those who dare challenge Microsoft is both a necessary blessing and guaranteed curse. Take for instance the widely held assumption that Microsoft invented MS-XML (OfficeOpenXML) in response to OpenDocument (ODf). This is false, misleading and will inevitably result in a FOSS death spiral in the face of a Vista Stack juggernaut. But it sure does feel good.

    Joe Wilson at Microsoft Watch points out the real reason for MS-XML, and why ISO approval of OOXML is so important. Microsoft needs OOXML approved as an international standard because OOXML is the binding model for the emerging Vista Stack of loosely coupled but information integrated applications.

    The Vista Stack model converges desktop, server, device and web information systems using OOXML-Smart Documents, .NET 3.0 and the XAML presentation layer as the binding components.

    The challenge for Microsoft is to migrate existing MSOffice bound business processes, line of business integrated apps, and advanced add-ons to the Exchange/SharePoint Hub. Once the existing documents, applications (MSOffice) and processes are migrated to the E/S Hub, they can be bound tightly to the rest of the Vista Stack.

    Others see OOXML as some sort of surrender or late recognition that the salad days of MSOffice are over. They jubilantly point to Web 2.0, Office 2.0 and rise of the LiNUX Desktop as having ushered in this end of monopoly for MSOffice. Like the ODf champions, these people are similarly sadly mistaken!

    There must be something in the air.  The end user inspired idea that applications should be able to exchange documents perfectly preserving the presentation (man percieved appearance as opposed to machine interpreted layout-rendering) is gaining a rabid momentum.

    Yesterday it was the Intel ODF Test Suite results falling into the hands of Microsoft, who is now using the results to argue that OpenOffice doesn't fully support - implement ODF.  The Intel ODF Test Suite is notable in that the test is near 100% about comparative  "presentation" :: an object to object ocmparison of a KOffice document to an OpenOffice rendering of that document and vice versa.

    Today we have the EU IDABC hosting a continent wide conference discussing the same  issue :: the "exchange" of ODF documents.  They've even gone so far as to coin a new term; ODEF - OpenDocument Exchange Format!

    This morning i also recieved an invite to join a new OASIS discussion list, "The DocStandards Interoperability List".  The issue?  The converision and exchange of documents between different standards.

    And then there is the cry for help from Sophie Gautier.  This is an eMail that has worked it's way up to both the OASIS ODF Adoption TC and OASIS ODF Mainline TC discussion lists.  The problem is that Microsoft is presenting the Intel ODF Test Results to EU govenrments.  Sophie needs a response, and finds the truth hard to fathom.

    Now that's what i'm talking about!  Business documents published in an advanced Web Productivity RIA format.  Roambi Flow targets the iPAD with business reports based on SalesForce.com and other business productivity platforms hosting basic business intelligence and information.  Roambi packages the reports in the increasingly popular visually immersive webzine style similar to FlipBoard, Zite, TreeSaver, OnSwipe, Push Pop, Instapaper, Readability, Pulse, PressJack, TweetMag, Sports Illustrated and the NYTimes iOS editions.  Beautifully done.   My guess is that the underlying format is the visually rich and interactive HTML+ (HTML5-CSS3-JSON-JavaScript-Canvas/SVG). excerpt:  After revolutionizing the way companies can interact with their business data on the go with its Roambi app, San Diego-based startup Mellmo is now aiming to let you use that data to create gorgeous interactive reports and presentations with its new iPad app and publishing platform Roambi Flow. The move is the next step in Mellmo's plan to make business intelligence (BI) more accessible, and dare I say it, sexy. Mellmo's initial Roambi app integrates with existing BI systems, including Salesforce and SAP, letting business owners and executives easily make sense of their data with interactive charts, graphs and more. Now with Roambi Flow, that data can be used to create magazine-quality reports and presentations that can be shared more easily with any iPad user.

Official Google Blog: Pagination comes to Google Docs - 0 views

    Although you need Chrome for the new Google Docs pagination feature, the key here is that gDocs now supports the CSS3 pagination module!   excerpt: Today, we're doing another first for web browsers by adding a classic word processing feature-pagination, the ability to see visual pages on your screen. We're also using pagination and some of Chrome's capabilities to improve how printing works in Google Docs. Native Printing: Pagination also changes what's possible with printing in modern browsers. We've worked closely with the Chrome team to implement a recent web standard, CSS3, so we can support a feature called native printing. Before, if you wanted to print your document we'd need to first convert it into a PDF, which you would then need to open and print yourself. With native printing, you can print directly from your browser and the printed document will always exactly match what you see on your screen.

Microsoft Will Support ODF! But Only If It 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.
