description
Successful preservation of content requires sophisticated mechanisms for collecting, tracking and analyzing information about a multitude of relevant aspects. This is not limited to content itself, but also tracking of available software, other organization’s content, usage statistics and trends, format risks, systems operations and many more. Such tracking requires a flexible system that supports evolution over time and provides an extensible platform for scalability. This presentation describes the system design of a novel approach towards automated monitoring of preservation-related information. We discuss the challenges and information sources that need to be covered, and describe the architecture and data model of a novel preservation watch system, currently under development. We discuss how this system addresses critical information needs for informed preservation management and outline next steps ahead.

State of the Art
• Digital Format Registries
• AONS
• Technology watch reports
SCAPE

State of the Art
• Digital Format Registries• Lack of coverage
• Statically-defined generic risks
• Lack of structure in risks
• Focus on format obsolescence
• AONS• Total dependency on format registries
• Technology watch reports• Machine unreadable

What is needed?
• We need data!• From anywhere and everywhere
• Sharing
• Usability & Scalability• Structured data
• Controlled vocabulary

Methodology• Survey practitioners on information to be monitored
• Create structured data model
• Find sources of information (try to automize)
• Define notification triggers
• Frequent monitoring of sources of information
• Frequent assessment of triggers and notification
SCAPE
17
Example questions
• Are there any tools that can render the format X?
• Is my repository the only one that has format Y?
• Are my preservation plans still valid?
• Are my repository policies being enforced?
SCAPE

Information Sources
• Format registries & software catalogues
• Digital repositories & web archives
• Organizational objectives
• Experiments
• Simulation
• Human knowledge
