3. Superimposed Information - ICDE 2001 - Heidelberg3 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

4. Superimposed Information - ICDE 2001 - Heidelberg4 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

5. Superimposed Information - ICDE 2001 - Heidelberg5 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,...

12. Superimposed Information - ICDE 2001 - Heidelberg12 (Wild) Bundles

13. Superimposed Information - ICDE 2001 - Heidelberg13 (Wild) Bundles There is benefit in creating (active processing of information) There is benefit in reusing (trigger memory) There is benefit in sharing (establish collective, situated awareness)

14. Superimposed Information - ICDE 2001 - Heidelberg14 Given…. bundles are everywhere! access to bundles provides access to important information information in bundles is often copied from other information sources we can keep copied/referenced information linked through the use of marks

23. Superimposed Information - ICDE 2001 - Heidelberg23 Future Work Field trial of SLIMPad (e.g., Saturday rounds) Validate bundles/SLIMPad results in 2nd application Extend SLIMPad, perhaps suited for a medical task Extend architecture Extend the metamodel (to accommodate more data models) Formalize the metamodel Develop addressing mechanisms to accompany structural constructs (to support canonical marks)

27. Superimposed Information - ICDE 2001 - Heidelberg27 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.

34. Superimposed Information - ICDE 2001 - Heidelberg34 Things we’ve learned from Task 1 NSF Digital Government work is project-based primary product is information: assessments, studies, surveys, environmental impact statements multiple agencies are involved each agency serves as information gatherer; information broker; information consumer even though information is a primary product, information technology is secondary (stewardship of the land is the primary mission)
