Industry Trends

  • Increasingly complex documents
    • Documents are assembled from multiple applications
    • Digital colour components rely on multi-vendor system-wide colour fidelity
    • Blended overlaid content layers (transparency / alpha blending)
  • Print related costs are significant for Fortune 500
    • Benefit from an efficient bridge between electronic form and paper – a simple enough to validate, complete enough as both an electronic record and paper
  • Peripherals becoming more intelligent
    • Participate on networks without a host
    • Hardware costs drive the need for an efficient print format
  • Increasing use of 3D in displays, printing, document exchange
    • Standardized 3D object format is available to be included in electronic paper format

document life cycle requirements
Document Life Cycle Requirements

Authoring document formats

Information content is the primary value

Full editability and round-trip capability must be retained

Document format intimately tied to document usage to maximise retention of semantics

Often advantageous to allow re-flow for reading devices with different form factors, e.g., computer screens, mobile devices and printed output

Distribution document formats

Information content and appearance are both valuable

Appearance must often be guaranteed between screen and printed views

Confidence in fidelity and trustworthiness is more important than editability

Document format not tied to semantics, allowing broader application in more use cases

Format should be self-contained

using xml for file formats
Using XML for file formats …
  • Simplifies low-level file creation and reading
    • A wide variety of tool-sets are available
    • Increases choice of applications because of lower cost of entry for vendors
  • Increases robustness
    • Schema validation allows more frequent and more complete testing of created files
    • Allows easy diagnosis of faults in document workflows
    • Schema validation can be enhanced by grammar-specific test tools
  • Enables cross-application functionality
    • XML is now widely used in information transfer
    • XSL-T (and other tools) can be used to translate between different grammars
    • Data can therefore be extracted or inserted into XML documents
  • Standardising XML grammars moves innovation to user-visible issues
    • Differentiation no longer focused on file format handling, but on real user benefits in application functionality
tc46 objectives
TC46 Objectives
  • Program of work addressing the industry trends:

1. Produce a standard for an XML-based electronic paper format and XML-based page description language based on existing implementations of the format called the XML Paper Specification, including:

      • Produce a fully documented and unambiguous standard for an XML-based electronic paper format and page description language
      • Produce appropriate W3C XML Schemas to enable automatic verification of files written to the standard

2. Assume responsibility for the ongoing maintenance and evolution of the OpenXPS Ecma International Standard

3. Develop standards while keeping compatibility with applications, devices, tools and platforms implementations based on prior XML Paper Specifications in mind

4. Evaluate and consider proposals for complementary or related additional technologies

5. Establish and maintain liaisons with other Ecma TCs and with other Standards Setting Organizations (SSOs) as appropriate to facilitate and promulgate the work of the TC

6. Evaluate and consider contributing the Ecma standard to an ISO and/or IEC TC for approval and adoption

tc46 terms of reference
TC46 Terms of Reference
  • Scope:
    • The goal of the Technical Committee is to 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 (XPS)
    • The Technical Committee will use the format called the XML Paper Specification (XPS) as a starting point with the aim to provide a standard, secure, and highly trustworthy format that enables a wide set of applications, devices, tools and platforms to implement compatible paginated-document workflows
    • An additional goal will be to enable the interoperability of independently created software and hardware systems that produce, consume or otherwise process OpenXPS content
    • The Technical Committee will be responsible for the ongoing maintenance and evolution of the standard

overview of openxps
Overview of OpenXPS

A standard for a document & print-stream format

  • Bridges electronic and physical paper
  • Addresses scanning, sharing, publication, printing & archiving phases of document lifecycle
  • Accurately represents the physical page
    • Content doesn’t change
    • Layout is fixed
    • Format contains all resources
  • Trustworthy by design
  • Simple implementation
  • Platform independent
openxps is based on standards
OpenXPS is based on a number of other standard (de facto or de jure) technologies:

Open Packaging Conventions & Markup Compatibility (ECMA-376)

ZIP (Physical Package as defined in OPC)

Simplifies aggregation of XML and binary content

OpenType and Unicode

Open Font Format (ISO/IEC 14496-22:2007)

The Unicode Standard, Version 4.0

Unicode Character Database, Revision 4.0.0

International Color Consortium (ICC) colour profiles

Colour transform data format, ICC.1:2001-04,ISO 15076-1

Standardized colour encodings

IEC 61966-2-1, IEC 61966-2-2

TIFF, PNG, JPEG

Widely used image formats, supporting a variety of colour spaces, bit depths and compression algorithms (lossless and lossy)

JPEG XR

Standardized in ITU-T Rec. T.832 and ISO/IEC 29199-2

OpenXPS is Based on Standards
openxps implementation benefits
OpenXPS Implementation Benefits

Defined for trustworthy document communication and high fidelity reproduction

Validation against defined XML schema (no DTD)

Non-programmatic

No subsetting (one format, not a family of formats with different requirements subsets (‘profiles’))

Feature set limited to electronic paper (2D and 3D)

Rely on pre-existing standards and broadly-based specifications

Developers can utilize hardened codec

Workflow interoperability support

Clear delineation of producer and consumer responsibilities

Enables both streaming and random access

Widely used image formats, supporting a variety of defined colour spaces, bit depths and compression algorithms (lossless and lossy)

Intentionally IP royalty free, “OpenXPS” trademarked by Ecma

Easy progression from existing XPS implementations

XPS and OpenXPS content can be easily distinguished

Existing XPS consuming implementations can be updated to support OpenXPS content with only minor modifications

minimal incremental development tool costs
Minimal Incremental Development Tool Costs

OpenXPS use of standard components enables use of a broad range of existing tools, including open source:

XML

ZIP

OpenType/Open Font Format fonts

ICC colour management

TIFF, PNG, JPEG

Tools written chiefly in C, C++ and/or Java

Minimal cross-platform portability issues

Tools for OPC rapidly emerging
