I just wanted to inform everyone, if you did not already know, that Microsoft is coming out with a new file format call Metro that is suppose to be released with Windows Longhorn. Since Microsoft formats seem to be big seller at Aspose I thought that you may want to get a component out there before the Windows Longhorn release. The following link has some info on the up and coming format: .<o:p></o:p>

Thank you,<o:p></o:p>

Thank you for your sharing and I also noticed this news but I did not find any technical details about this new file format.

If this news finally becomes a product, I assume customers would need to save Word, Excel, PowerPoint to Metro. So we would closely track how Mero will go.

To All,

Another Article on Microsoft's new document format: Metro.

and a link to their beta app Acrylic:

Thank you to share it.

I installed Acrylic but I must say it’s premature. Also I failed to find more info about Metro file format. I even could not save the imgae into pdf documents.

Let’s look forward its RTM version.


Technically, Metro will be part of WinFX, the new application programming interface (API) for Windows Longhorn, although versions of WinFX will be made available to users of Windows XP and above. Since WinFX will be built in to Longhorn, the timeframes are the same, although WinFX’s – and hence, Metro’s – reach will be significantly larger than that of Longhorn itself.

XML Paper Specification

Windows Vista? introduces a modular content framework called XML Paper Specification (XPS-formerly code name “Metro”) that enables end users to manage document security and digital rights, annotate and track document history, and to display or render the documents through multiple technologies, including desktop views, streaming downloads, printers, and Web pages.

The XPS framework supports these functions by allowing document developers to design new self-describing information formats. Windows Vista supplements the power and generality of the XPS framework with a specific document implementation called the reach package (also known as XPS Reach). XPS Reach supports many of the most common user needs by providing an optimized format for working with paginated documents.

XPS Framework

XPS documents are programmatically created and accessed through the Windows Presentation Foundation Document Services (System.Windows.Documents) and also through the package model (System.IO.Packaging). To work with XPS documents, a developer needs to do three things:

  • Use the package model. Under the XPS framework, a package is a logical entity serving as a container for constituents. These constituents are called parts, and each part is defined by a name and a content type. Parts can contain references to other parts in a package, or to external resources. The XPS framework provides a higher-level mechanism to describe these references, called relationships, which make the reference directly discoverable without needing to look at the content in a given part.
  • Map the abstract package to a physical format. A package is an abstraction that represents the structure of a document. The package model may be mapped to an actual entity (referred to as a physical format). A physical format can be almost anything: a file, an archive (such as a ZIP file), as well as various transports (such as network-based protocols). In fact, a single XPS framework format can have expressions in multiple physical formats, such as a ZIP file on disk or a network protocol for a Web service.
  • Supply the XPS framework metadata. The metadata of an XPS framework-based document describes the document’s content and use, and is discoverable (along with its package structure) through the XPS framework APIs. This provides the basis of the portability and device independence of XPS framework-based documents. In addition, the XPS framework provides a well-defined means for including a digital signature, digital rights management information, and other security features in its metadata. The metadata is fully extensible and can be used to contain such items as information in annotations and thumbnails.
XPS Reach

The XPS Reach package provides a specific implementation of an XPS framework designed to address the information worker’s requirements for distributing, archiving, rendering, and processing documents.

A document in XPS Reach format is expressed in a neutral, application-independent way so that the content can be viewed and printed without the application used to create the package.

The XPS Reach format uses a well-defined and fixed-format layout, including pagination for its content, while still allowing for versioning or other expansion.

Effectively, the XPS Reach format defines a default electronic paper object for Windows Vista?, and is used to define the Windows Vista print architecture, as well as the native Windows Presentation Foundation print output.

The WinFX SDK documentation includes many references to the XPS data format, all of which center on the XPS Serialization Manager class (System.Windows.Reach.Serialization in the ReachFramework assembly).
