The Public Sector Information Exchange (PSIE)
The Public Sector Information Exchange (PSIE)
The chapter explains the concept of a Public Sector Information Exchange (PSIE). It then presents a detailed case study of a supply-chain PSIE model: the Australian CrimTrac program that was established to streamline information sharing among Australian police organizations. The chapter then explores the potential for an exchange PSIE model to be implemented in a US public sector agency in the environmental domain. Economic, legal and technical challenges to an exchange-model PSIE are outlined in detail. A case study of the deNovis project shows how semantic interoperability challenges could be overcome.
