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, ...
The superimposed and base layers with marks Superimposed Layer marks Base Layer Information Source1 Information Source2 Information Sourcen … Focus: building generic technology
Styles of Superimposed Applications superimposed application base application1 web browser (with extra functions such as annotation) ... base application2 enhanced base layer application simultaneous use of base and superimposed applications

(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)
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
SLIMPad demobuilt using our architecturesimple applicationminimal interface to base layer (create mark, go to mark)
Outline • introduction to superimposed information • application of our work • SLIMPad (NSF Digital Libraries 2 Program) • our architecture for building superimposed applications
Superimposed Layer Information Manager (SLIM) Architecture:Contributions • Mark Management - to create/resolve marks • SLIM API - for the application developer • TRIM store - for generic storage of superimposed information
Storing Superimposed Information • Provides a level of abstraction above models • Describes the structural features of models Basic Set of Abstractions Metamodel Model Constructs and Relationships Topic Map XML Topic Map Defintions Schema-Level Data DTD Topic Map Instances XML Document Instance-Level Data
Model, Schema, and Instance data - all represented uniformly using triples
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)

Harvesting Information to Sustain our Forests: Creating an Adaptive Management Portal NSF DIGITAL GOVERNMENT PROGRAM Tim Tolle & Lois Delcambre ttolle@fs.fed.us lmd@cse.ogi.edu Co-Project Directors
Project focuses on the: Adaptive Management Areas USDA Forest Service USDI Bureau of Land Management USDI Fish and Wildlife Service
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.

Task 1 – Status • Workshops @ Snoqualmie Pass Adaptive Management Area, Cle Elum, WA (June and July) • Interviews with Forest Service Corvallis Forest Sciences Lab and USGS FRESC, Corvallis (August) • Interviews with Central Cascades Adaptive Management Area, Eugene (August) • Interviews with the Applegate Partnership and its associated agencies (August) • Rainier National Park (planned for October)
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)
