Presentation Transcript
  • Why Open XML?
  • Controversy!
  • Current status of Ecma 376 at ISO
  • Why are standards important?
  • What are the different standards bodies for?
  • Introduction to Ecma 376
  • Adoption issues
importance of interoperability

Achieve industry alignment using standardized technologies.

Enable data interoperability between documents, applications and systems.

Capture and reuse information to and from many data sources.

Build intelligent applications that improve data context and quality.

Importance of Interoperability

Shared service oriented architecture

(fx http, XML, SOAP, WSDL, UDDI)


Interoperability for DocumentsThe role of XML-based document formats in the Microsoft® Office system

Business Process Efficiency

Improved Data Access

Business requirements

Company standards

Customer details, Costs

Web service


intelligent receipt

Efficient capture

Validated information

Query & extract





Document Assembly

Searching &



Auto-creating a

polished document


XML structure

Data and presentation



RFP Content


Document Archival

Archived & consumed long into the future

without vendor-specific clients or applications

xml based formats enable you to do things you couldn t before
XML-based formats enable you to do things you couldn’t before
  • Better value from existing infrastructure
    • Information security
    • Regulatory and process compliance
    • Information integration
    • Retention, discovery and content management
    • Documents as digital assets – what are you worth?
    • Legacy documents & archives
    • Lifecycle cost vs. Implementation cost

Documents that manage themselves

Managing documents with systems

  • Understanding IT impact of XML-based formats
    • Application compatibility
    • Layout and rendering fidelity
    • Deployment & migration
    • Existing solutions / integrations
    • Storage & bandwidth

Enabling the future

Preserving Legacy

different scenarios of xml based formats
Different scenarios of XML-based formats
  • Past
    • preservation and archiving
  • Present
    • fidelity versus interchange
  • Future
    • document engineering and systems integration
  • Open XML developed (too fast, too recently) to stop ODF adoption
  • Ecma is a second-rate “rent-a-standard” organization
  • Not open standard
  • Three month review too little time
  • Open XML contradicts other ISO standards
  • ISO officials bribed or pressured
why i support open xml
Why I support Open XML
  • Document processing systems need published, stable standards
  • Plurality: spectrum of interoperability
  • Technical excellence
  • Engaging Microsoft
  • Pro-Open XML does not = anti-ODF!
  • Cross-breeding
four phases of standards
Four Phases of Standards

Standards for:

  • Character sets
  • Data and connection protocols
  • Web locations and resource metadata
  • Media: HTML, XML, JPEG, etc
  • Web services
  • Vocabularies
what is a technical standard
What is a technical standard?
  • An agreement
  • Between participating stakeholders and experts
  • With a market requirement
  • In a particular form
  • Developed with a fair process
  • With appropriate licensing and IP status
  • Suitable for public adoption
  • Periodically reviewed for maintenance or withdrawal
what are they for
What are they for?
  • Library of technologies
  • Niche and major markets
  • Corporate and regulatory adoption
win win
  • ISO processes
  • Secretariat tasked to keep process in order, not to do the work of committees or usurp the votes of NBs
are standards laws
Are standards laws?
  • Contrast with technical standards for health and safety
  • Legislators may adopt voluntary standards
  • Governments may be under treaty obligations, to promote standards, but need economic proof
  • With overlapping standards, no obligation to allow all of them
  • Standard as barrier to trade ?
can standards overlap
Can standards overlap?
  • ISO 8879 example?
    • Morphs into HTML at IETF the W3C
  • ISO Book 12083?
    • Replaced by OASIS Docbook
    • Morphed into XSL at W3C
    • From Adobe

Open XML Formats Architecture Modular format improves developer capabilities with minimal user impact

Office “file”

Operates identically to any other Windows desktop file. User sees and interacts with the desktop file exactly as they do with today.

Internal operation

Different types of data within each file stored as discreet, ZIP-compressed XML components

Users would not see these components unless they un-ZIP the file to view the document parts

Applications and systems could modify and extract individual parts without using Office applications

The corruption or absence of any part would not prohibit the file from being opened

  • 2007 Microsoft Office system - Default Save Format is Open XML (+ free updates for Office 2000, XP, 2003) – Dec 2006/Jan 2007
  • Open Office – Novell announcement of support of Open XML in Open Office – Novell edition
  • Corel announcement of support of Open XML - Availability mid 2007
file format compatibility ensuring free document exchange with prior office releases
Office XP, 2003 will open, edit and save new Office formats

Will recognize new Word, Excel and PowerPoint file format extensions

Enables users to Open XML Formats across multiple versions

Windows 2000 SP4 and later can convert between binary and Open XML Formats

Office 2007 users can change the default file format if desired

Current .doc, .xls, .ppt file formats will be supported in 2007 Office system

Default file format can be set by users during deployment or after

Advanced policy controls for enabling and disabling the use of specific formats
