LionShare Origins
• Visual Image User Study (VIUS)• Hosted in University Libraries at Penn State• A two-year user study sponsored by Mellon
Foundation• Looking at how fac/staff/students use digital
images in teaching, research and service• Several prototypes identified
– Peer-to-Peer was identified as one possible solution - LionShare prototype

VIUS Identified These Problems
• Need for tools to manage personal collections
• Rapid movement from analog to digital
• Difficulty in finding appropriate resources
• Difficulty merging public/private collections
• Need for faculty/student/dept’s to manage large collections
• Need for copyright and access control

Why Use P2P for LionShare?
• Encourages collaboration– Student, faculty members and departments
• Helps manage the digital media explosion– Digital consumer devices
• Provides common organizational structure– Metadata and standards
• Flexible and Scalable– Customizable for different needs

LionShare Design Goals
• Media management
• Simple, intuitive interface
• User-defined sharing
• Authenticated access to the network
• Standard descriptive metadata structure
• Leverage open source and open standards

LionShare PrinciplesThe Three A’s
• Authentication Agnostic– Federated Identity
• Authorization– Access Control
• Accountability– Non-anonymous network
• UserID associated with shared files• Activity logging

LionShare Basics
• Based on Limewire Open Source project
• Modified version of the Gnutella protocol– P2P + Client/Server Architecture– Decentralized + Centralized Topology
• AuthN/AuthZ – using Shibboleth Phase II
