Philosophy Underpinning v Enable trusted systems to interoperate for end-to-end DRM v Single language across all media types, platforms, formats, resources, products & services to facilitate interoperability v Application/domain agnostic structure v Comprehensive to express wide variety of business models v Application to all phases of life cycle v Extensible to allow adaptability and minimize future cost of change v Ease of implementation and deployment 6

What is OASIS? v Standards are created under an open, democratic, vendor-neutral process w Any interested parties may participate, comment w No one organization can dictate the standard w Ensures that standards meet everyone’s needs, not just largest players’ v Open to all interested parties…. . Individual Memberships v All discussion open to public comment v One organization/One vote v Resulting work is guaranteed to be representative of the industry as a whole, not just any one vendor’s view 9

Where OASIS Fits OASIS, industry associations Vertical industry applications OASIS Horizontal, e-business framework W 3 C, ISO XML, XSL, namespace, DOM, etc. IETF Core protocols, messaging; e. g. HTTP 10

What is Xr. ML? v Xr. ML – e. Xtensible rights Markup Language v Originates from Xerox PARC in 1994 v Provides a universal method for securely specifying and managing rights (and associated conditions) for all kinds of resources including digital content and services v Supports content integrity and entity authentication and confidentiality within the specification v Encodes in XML, leverages standard XML schemas, namespaces, digital signatures etc. v Is highly flexible, customizable, and extensible v Is available at www. xrml. org 14
