Crisis, Tragedy, and Recovery Network (CTRnet)
• Build a networked digital library relating to CTR
• Integrate community, content, and services relating to CTR, making it accessible, and preserving it for long-term reuse
• Support information exploration
• Aided by an ontology

• Help affected communities to recover more quickly and effectively– Global network– Easy accessibility– Relevant information and resources
• Support classes of stakeholders in reacting to and recovering from crises– Researchers– Scholars– Emergency personnel– Decision makers– Public
Potential impact

A key part of the CTRnet would be an ontology to help make sense of information as well as connect content, community, and services.
