Outline
• introduction to superimposed information
• application of our work– SLIMPad: NSF Digital Libraries 2 Program
• our architecture for building superimposed applications

What is Superimposed Information?
data “placed over” existing information sources to:
highlight annotate elaborate select collect organize connect reuse
information elements
often to support new applications, beyond the original

Examples of Superimposed Information
Non-electronic examples:
Commentaries on religious texts, law, literature Concordances, citation indexes
Electronic examples:
Your bookmark file in your web browser RDF metadata

Why work on it now?
• Broadening range of digital information
• Accessibility/addressability to base information
– Reference (e.g., URL) can be resolved quickly– Addressing at various levels of granularity
• Emerging Standards: RDF, Topic Maps, Xlink
• Emerging Applications: – Third Voice, Multi-Valent Documents, ...

Superimposed Information - ICDE 2001 - Heidelberg 27
Adaptive Management Portal: a value-added, Internet-based service
• Provide multiple access paths to forest information.
• Preserve local autonomy and local focus of each site.
• Support diverse users and types of information.
• Use proposed, existing, and de facto standards for content, classification, and technology.
• Be low-cost, scalable, extensible.
