Store Front Rights Clearing User Interface Digital Rights Meta Data Digital Identification 3. DRM 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

4. What is?

  • XrML eXtensible rightsMarkupLanguage
  • 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 highlyflexible, customizable, and extensible
  • Is available atwww.xrml.org

5. 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

6. 2.0 Is Built On Standards

  • XML 1.0 Specification
  • XML Schema
  • Namespaces in XML
  • Uniform Resource Identifiers (URI): Generic Syntax
  • Digital Object Identifier (DOI)
  • ISO 3166 Codes for representing names of countries
  • ISO 4217 Codes for representing currencies and funds
  • XML Path Language (XPath) Version 1.0

7. 2.0 Supports or May Utilize Additional Industry Standards

  • Dublin Core Metadata Initiative
  • Resource Description Framework (RDF)
  • Universal Description, Discovery and Integration (UDDI)
  • Web Services Definition Language (WSDL)
  • XML-Encryption Syntax and Processing
  • XML-Signature Syntax and Processing


  • Granting Mechanisms
    • Grant
    • License

2.0 Core Structure Right(view, play,print, copy, forward, etc.) Resource (work, service, name, etc.) Condition(fee, time,geography, etc.) Principal (person, Device, application, etc.)

  • Four Key Components

9. Business Models Supported in

10. 2.0 Highlights

  • Mathematical Precision no ambiguity
  • Expressiveness advanced business models, life-cycle management, usage state tracking, pattern matching
  • Well defined core and extensions architecture
    • Compact: Use of only those terms needed
    • Applications based on equality & pattern matching enable extensions without the need to upgrade
  • Comprehensive Security
    • Entity authentication (Users, software, hardware,Digital Items, etc. )
    • Integrity and confidentiality of rights expressions
  • Up-to-date Standards and Technologies

18. Summary

  • Progress beginning on interoperable DRM standards
  • DRMs 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
