• 3 State Government
agencies
• Without constraining the
decisions of partner
agencies w.r.t. the
implementation and
development of their own
systems

– reduce costs and improve
quality of data available to
local and state government
– streamline information
sharing among councils and
relevant government
agencies
– improve access to and value
of information for councils,
government agencies and
the public

Conclusion
• New styles of
information system
require new design
approaches based on
information
infrastructure
• Developing workflow,
wrapper kits, resource
discovery and query
planning
