OpenXPS - OpenXML Paper Specification
At the 97th General Assembly held in Budapest, June 16, 2009, Ecma International approved Open XML Paper Specification (OpenXPS) as an Ecma standard (ECMA-388).
This Standard defines OpenXPS, the Open XML Paper Specification. OpenXPS describes a set of conventions for the use of XML and other widely available technologies to describe the content and appearance of paginated documents. It is written for developers who are building systems that process OpenXPS content.
A primary goal is to ensure the interoperability of independently created software and hardware systems that produce or consume OpenXPS content. This Standard defines the requirements that systems processing OpenXPS Documents must satisfy in order to achieve interoperability.
This Standard describes a paginated-document format called the OpenXPS Document. The format requirements are an extension of the packaging requirements described in the Open Packaging Conventions (OPC) Standard. That Standard describes packaging and physical format conventions for the use of XML, Unicode, ZIP, and other technologies and specifications, to organize the content and resources that make up any document. They are an integral part of the OpenXPS Standard, and are included by reference.
Many XML-based building blocks within OpenXPS make use of the conventions described in the Markup Compatibility and Extensibility Standard that is relied upon by the OPC Standard to facilitate future enhancement and extension of OpenXPS markup. As such, that Markup Compatibility and Extensibility Standard is included by reference.
It’s about time the world had a XML based non-revisable document standard. A White Paper is also available here in PDF format and here in XPS format
