DRM Definition

DRM has always had a “security/protection” emphasis

Broader definition “Digital Rights Management (DRM)

involves the description, identification, trading, protection, monitoring and tracking of all forms of rights usages over both tangible and intangible assets including management of Rights Holders relationships”

W3C DRM Workshop

DRM Workshop, January 2001 <http://www.w3.org/2000/12/drm-ws/> 65 Attendees, Position Papers, Minutes,

Reports, Presentations Outcomes:

Concerns over Privacy and Accessibility Balance needed between Protection and

Access W3C should investigate a “Rights

Management Framework” for Interoperability Start some smaller Working Groups (eg

Language) Bring work of other groups together


Conclusion

DRM is emerging as a new way to Enable innovative new business models Foster more Content online

Everyone wants DRM solved but its not an easy solution to generalise

DRM technologies are “embryonic” but evolving fast… DRM technologies need to meet all the

needs of Rights Holders and Consumers (Web Users)

W3C: “Leading the Web to its Full Potential” DRM is that potential . . .
