Packaging Provides foundation of a file format Described in the Open Packaging Conventions Specification v0.9 Usable by any application Multiple implementations underway XPS Document Office 2007 Open XML formats

More than just Zip Allows for related collections of files Provides means to identify file types Provides Digital Signing Provides a basis for Rights Management

Custom File Formats Data can be logically separated into files Relationship tree organizes data Content Types identify data types

Custom File Formats Take advantage of common package services E.g. core properties, digital signatures Packages can contain multiple formats Interleaving provides simultaneous production and consumption

XML Paper Specification (XPS) Interoperability of independently created software and hardware systems. Usable by any application Human Readable Can be developed with access to common PKZIP and XML libraries

Developer Scenarios Any.NET 3.0 Visual tree can be serialized as XPS Any application that can print can generate Xps using the Xps Document Writer Packaging can be used to generate multi- format documents

Conclusions Printing-Traditional means to distribute data We empower developers by allowing more hooks into the printing process. Other Developers can cooperatively extend printing functionality Allow better user experience by providing better methods to communicate with the driver Packaging – Improve on traditional methods of electronic distribution Relationships allow for file association Digital Signatures and Rights Management improve security File Content types allow for type identification for easier consumption Publishing – XPS provides easy way to electronically distribute paginated data Wide distribution of viewing software (XPS Viewer ) Ease of production with.NET 3.0 and legacy applications] Open specification makes XPS available to everyone
