## Digital Data in Networked Environments

- Current Model
- Information assumed to be transient
- Web pages - CNN, Google, etc.
- Information assumed to be semi-permanent
- PDF, Word, email, etc.
- But it is all bits - easily kept, altered, replicated, re-disseminated, etc. --- hard to manage
- And it all exists in some IPR context

## DRM: evolving technologies & businesses
Goal - enable content owners to define and possibly control access to and use of content
Digital Management of Rights

## Rights Expression Language (REL)
State the rights such that they can be ‘understood’ by computers
Standardization is vital
XrML is an emerging standard

Define the terms used in the REL
Problem - multiple vocabularies
<indecs> project attempts to mediate

## XrML

- Corporation for National Reserch Initiatives

## Simple pointer in content to a fixed location for encoded policy
Problem - things move (404)
Persistent identifiers linking content and encoded policy
Requires resolution system and more standards
Tight binding of content and policy
Can’t have one without the other
Problem - can never change the policy
