DRM RequirementsDRM Requirements

Trusted Systems that … Secure and protect digital contents and services

across the value chain Persistently honor usage rights, conditions and

obligations specified for digital contents and services

A Common Language that … Provides a uniform mechanism to describe

specifications of rights and their conditions and obligations for distributing and using digital contents and services

Enables trusted systems to exchange digital contents and interoperate for end-to-end DRM

What is ?

XrML – eXtensible rights Markup Language Originates from Xerox PARC in 1994 Provides a universal method for securely specifying

and managing rights (and associated conditions) for all kinds of resources including digital content and services

Supports content integrity and entity authentication and confidentiality within the specification

Encodes in XML, leverages standard XML schemas, namespaces, digital signatures etc.

Is highly flexible, customizable, and extensible

Is available at www.xrml.org

Philosophy Underpinning

Enable trusted systems to interoperate for end-to-end DRM Single language across all media types, platforms,

formats, resources, products & services to facilitate interoperability

Application/domain agnostic structure Comprehensive to express wide variety of business

models Application to all phases of life cycle Extensible to allow adaptability and minimize future cost

of change Ease of implementation and deployment

SummarySummary

Progress beginning on interoperable DRM standards DRM’s full potential requires applicability across

Content centric businesses Enterprise applications Web services

A dynamic standard (e.g. XrML) can facilitate required extensibility Adapt to a changing future Reduce possibility of standards fragmentation

Digital Rights Language is an essential but only one of several initiatives needed
