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 Corporation for National Research Initiatives

Digital Rights Management (DRM) • DRM: evolving technologies & businesses • Goal - enable content owners to define and possibly control access to and use of content • Digital Management of Rights – Not management of digital rights • Human readable or machine actionable? – Natural language vs machine encoding • Define or Enforce? – Define: policy can be known – Enforce: constrain behavior to follow policy • How to express policy and connect it to content Corporation for National Research Initiatives

Encoding • Rights Expression Language (REL) – State the rights such that they can be ‘understood’ by computers – Standardization is vital – Xr. ML is an emerging standard • Rights Data Dictionary (RDD) – Define the terms used in the REL – Problem - multiple vocabularies – <indecs> project attempts to mediate Corporation for National Research Initiatives

Associate Encoded Policy with Content • 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 Corporation for National Research Initiatives
