The ResearchChannel Consortium
An intellectual community, we make knowledge available to all by sharing our developments,insights and discoveries with a global audience.
We bring together ideas from many of the world’s premier academic and research institutions and disseminate those ideas to the public directly,without interference.
We are committed to technological innovation toenable leading-edge exchanges of our resources.

Why?
To advance global networking technologies
To explore new methods of media distribution and sharing for teaching learning and research
To further multidisciplinary multinational scientific collaboration
Because the consortium is uniquely qualified to do so
Think Forward. Think ResearchChannel.
ResearchChannel is a collaboration among experts in Internet networking, storage/search infrastructure development, emerging streaming media and interactive technologies, digital television engineering, and video production.
On the Leading Edge

DigitalWell: HD Storage
Project Focus
• Easy way to acquire, collect, classify, store ,deliver large collections of digital media over IP networks.
• Proxy for any type of large data sets but initially focused on video and audio assets
• Includes broadcast/Internet Integration
• Exploits next generation networking to ensure high quality – Deliver Realism
• Easy-to-use Web services-based interface compatible with current Web browsers and computing platforms.
• Uses pluggable authentication to ensure security and control access to collections.
• Scalable architecture ensures that collections can be built, accessed, searched and shared between disparate networked communities.
• Middleware – integrates easilyMetadata, DRM/IP, AAI, API, Grid
• Automation – End to EndCapture, Describe, Preserve, Deliver

SRB being layered underneath DigitalWell to allow sharing of content
Enables digital library systems to communicate using their metadata
Examples of libraries that can communicate using SRB: MIT’s DSpace, Cornell’s Fedora
Important step in being part of BIG science

Neptune – “a fiber optic cable to inner space”
http://www.neptune.washington.edu/pub/whats_neptune/whats_neptune.htmlGoals:• to establish a regional cabled observatory in the northeast
Pacific Ocean 2,500-km network of fiber-optic/power To be built across the Juan de Fuca tectonic plate in the northeast
Pacific Ocean • Locate between 15 and 20 experimental sites at nodes
along the cable. sites will be instrumented to interact with Sensor networks will fill in the volume between nodes Multipurpose robotic underwater vehicles will reside at depth,
recharge at nodes, and respond to events • Via the Internet, provide real-time information and
command-and-control capabilities to shore-based users.
