Background Formed in spring 2001 Spent some time naming and scoping Critical insight and momentum from ViDe & Mace & Shibb leaders Focus now on videoconferencing and video-on-demand for their middleware requirements Component of NSF Middleware Initiative (NMI) NMI-EDIT http://www.nmi-edit.org/ 5/5/2019 CAMP2002, http://middleware.internet2.edu/video/

Vidmid VoD VidMid Video-on-Demand Chair, Mairead Martin, The University of Tennessee Goals: Enable effective and secure access to digitalvideo resources Ensure judicious use of digital video resources Coordinate with international metadata efforts Engage industry players 5/5/2019 CAMP2002, http://middleware.internet2.edu/video/
Vidmid VoD status Draft of VoD scenarios online http://www.ait.utk.edu/VidMid/VoD/scenarios/scenarios.html White paper on role of directories in VoD Will be included in NMI 1.0 release (April 2002) Exploring use of Shibboleth in Digital Rights Management. 5/5/2019 CAMP2002, http://middleware.internet2.edu/video/
Access to Digital Materials Digital Rights Management is about content control Several ways to use digital materials: personal use typically purchased by individuals on a subscription or per-use basis. professional use typically acquired (for fee or legal agreement) by an organization or university on a bulk basis, with access redistributed freely to members of the organization. public use as a citizen, entitled to an information commons, and other basic information rights, such as Fair Use and Freedom of Information 5/5/2019 CAMP2002, http://middleware.internet2.edu/video/
Digital rights technologies The different uses of on-line materials have different requirements they will likely require different technologies. Requirements vary about the needs and controls for privacy, the economic recovery model, the needs and controls for security, etc. e.g. ability to snip fair use clips Who is developing the digital rights technologies for professional and public use? 5/5/2019 CAMP2002, http://middleware.internet2.edu/video/
