  1. An IT Research View on SDI futures Dave Abel CSIRO Enterprise Distributed Systems Technology CRC

  2. Roadmap • SDIs and purposes; • Research agendas; • Interoperability goals; • The IMP architecture; • The IAW project.

  3. SDIs Many interpretations, goals differ significantly. An SDI is a collection of data sources and geoprocessing facilities, contributed by many autonomous units, with infrastructural support and standards.

  4. Layered Objectives An SDI should enable: • advising availability of data sets; • on-line access to data sets; • applications integrating data from several sources; • applications integrating data with use of geoprocessing services.

  5. Research Agendas A rich, interwoven mix of issues: • organisational; • informational; • technical; • exploitation.

  6. Distinctive Aspects • Immense collections of resources; • High rate of technical change; • Forms of exploitation that are still largely “to be determined”; • High (and continuing?) heterogeneity; • Federated model.

  7. Tests of Interoperability • a low cost of infrastructure to enable interoperability; • a high degree of provider autonomy; • the ease for a provider of participation; • the ease of accessing services and deriving data products; • the breadth of tasks supported; • scaleability in the number of data services present.

  8. The Internet Marketplace Model APPLICATIONS (customers) The Internet SERVICES (providers)

  9. The Glue • Two types of services: data supply and geoprocessing; • a common language (the RSL) to request supply of data or processing; • XML for delivery of data (but …); • Internet protocols for connection and interaction.
