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

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 …
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 uservisible issues
•
Differentiation no longer focused on file format handling, but on real
user benefits in application functionality
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 XMLbased 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
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
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
Addresses Industry Trends
Trend
Key OpenXPS Features
Increasingly complex documents
assembled from diverse applications
Complete graphics model, defined colour,
clarified for consistent rendering
Increasing financial and
environmental costs of unmanaged
printing
Bridge between physical and electronic
paper supports workflows that use
streaming
More intelligent document peripherals
are moving to become 1st class
citizens in a document workflow
A format that enables rich document
handling efficiently without requiring
programmatic resources
Increasing use of 3D models and 3D
prototyping, expanding the need for
an electronic format to physical
output bridge from 2D to 3D
Optional extension for 3D content uses X3D
Specification Web3D, streamable and XML
based, conforming to the X3D
“Interoperability” conformance level:
ISO/IEC FCD 19775-1r1:200x, ISO/IEC
19776-1:2005, or ISO/IEC 19776-3:2007
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
•
•
•

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
•
•

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
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
