Conceptual Basis Introduction
ADEPT Information Landscape Concept Prototype

• ADEPT
• prototype systems, extending the functionality
  of the ADL (Alexandria Digital Library)
• core set of InterLib services
• initial focus of supporting learning in a
  variety of contexts

• Information Landscapes (Iscapes)
• digital environments based on the Earth Metaphor
• information service layers with diverse
  information resources
• important attributes include
• easy, on-demand creation
• support for specific contexts, tasks, or
  requirements and
• support for collaborative use.

Introduction

Challenging applications Learning in the
context of the Digital Earth

• Sample information requests
• How does El Niño affect sea animals? Look for
  broadcast videos of less than 2 minutes.
• Look for all media sources on volcanoes in
  Hawaii and Italy. Also
  find how they cause/affect landslides and
  tsunamis.
• How do alluvial, high plains and Dakota
  aquifers affect plants? Look for all media
  sources.
• Find a new landfill site near the main source
  of a municipal refuse. The earthquakes
  impacts must be evaluated.
• Identify prospective 10 new shopping mall
  branches locations in the San Francisco Bay
  Area, from a simulation over the next 20
  years, all regions having a population
  greater than 25000 inhabitants and area greater
  than 1250sqft, having an urban land cover
  and moderate relief and also considering the
  transportation network.

ADEPT Information Landscape Concept Prototype

• Multimedia Collaboration supported by
• Synchronous DeskTop Conferencing
  (Video/Data/App) over a variety of media
• Asynchronous Web based shared XML/RDF/Iscape
  objects/components, and incremental building
• Integrated Multimedia
• Shared context based interaction support
• Adaptation of collaboration system CaTCH for
  Web- based collaboration (currently being used
  for healthcare)

Introduction

• Critical new value is to leverage currently
  independent information management, coordination
  and collaboration technologies for managing and
  exploiting the digital earth information and
  knowledge by multiple collaborators separated by
  space and time
• this will require increasing domain focus to
  solve more complex problems then attempted before
